Text messages




There is a display for text messages etc in the center of the upper section of the driver information module (DIM) (5/1). This provides the driver with supplementary information about the various warning symbols. This is to reduces the number of different symbols in the combined instrument panel. Other types of messages, such as the functions of the trip computer, are also displayed.
If the vehicle is equipped with the function automatic start/stop of engine guiding information is shown about the function.
For more information about the function, see Design and Function, Automatic start/stop of engine.
Depending on the situation, request for these messages may come from Central electronic module (CEM) (4/56) or Steering wheel module (SWM) (3/254).
There is an order of priority where all warning messages have precedence.

Outside temperature




The outside temperature gauge is integrated in the upper display. This function displays the outside temperature. If there is a risk of icy road conditions, a snow flake symbol is displayed to warn the driver. The snowflake is displayed in a range of -5 to +2 °C.
A sensor which detects the outside temperature is mounted in the left-hand door mirror (6/62). The temperature sensor is directly connected to the central electronic module (CEM) (4/56) which then forwards the signal to the driver information module (DIM) (5/1). The temperature is displayed in Celsius or Fahrenheit, depending on the market, in increments of one degree. The unit for temperature display is a programmable customer parameter.

Clock




The only function of the clock is to display the time in hours and minutes. The clock is in the upper display.
Information is transmitted from the central electronic module (CEM) (4/56) to the driver information module (DIM) (5/1) via the controller area network (CAN).
The customer can adjust the time using a knob at the bottom of the driver information module (DIM). During adjustment, the driver information module (DIM) transmits the new time to the central electronic module (CEM). The central electronic module (CEM) registers the change and updates its clock accordingly.
The customer can select the way in which the time is displayed:
- 12 hour clock. The time is automatically displayed with AM or PM
- 24 hours clock.

Seat belt reminder




The seat belt reminder reminds the driver to put on the seat belt. There are two versions of the seat belt reminder:
- European
- American.
The difference between the two is described below. The signals which indicate the variant (European or American) are transmitted by the central electronic module (CEM) (4/56) via the control area network (CAN). Two small symbols light by the lamp in the roof to indicate that the seat belt is not fastened. The driver information module (DIM) (5/1) emits an audible signal to warn the driver that the seat belt is not fastened.

European version (applies up to and incl. structure week 200650)
All the seats in the vehicle are monitored.
The light symbols will light in the Driver information module (DIM) and in the lamp module in the roof if the belt is not fastened when the ignition is switched on. There is an audible signal from the driver information module (DIM) when the vehicle speed exceeds 10 km/h. This continues for 6 seconds until either the seat belt is fastened or reverse gear is selected or the audible signal is switched off using the Read button on the control stalk. The audible signal's frequency increases at speeds exceeding 25 km/h and at speeds exceeding 40 km/h the volume also increases.
For the backseat there is status monitoring that generates various text messages depending on which belts are used. These messages are turned off 30 seconds after the vehicle has reached speed above 10 km/h.

European version (applies from and incl. structure week 200651)
All the seats in the vehicle are monitored.
Front seats:
The light symbols will light in the Driver information module (DIM) and in the lamp module in the roof if the belt is not fastened when the ignition is switched on. There is an audible signal from the driver information module (DIM) when the vehicle speed exceeds 10 km/h. This continues until the belt is fastened or reverse engaged. The audible signal's frequency increases at speeds exceeding 25 km/h and at speeds exceeding 40 km/h the volume also increases. If the loudest volume is activated, above 40 km/h, it will continue for 90 seconds even if the speed drops below 40 km/h.
Backseat:
For the rear seat there is a status monitor that generates different text messages depending on which seat belt is used. These messages go out 30 seconds after the vehicle has reached a speed greater than 10 km/h if a belt is fastened. If a belt is unfastened, the driver is alerted via text message as well as light and audible signals. The signals follow the front seat.

All messages can be switched off using the Read button on the control stalk.

American version (-2004)
When the ignition is switched on, the symbols light continuously for 6 seconds, or until the driver's seat belt is fastened. At the same time there will be a ringing sound from the driver information module (DIM) for the same period of time. If the driver then undoes the seat belt, the audible signal will not resume if more than 6 seconds have passed since the ignition was switched on.

American version (2005-2008)
When the ignition is switched on, the symbols light continuously for 6 seconds, or until the driver's seat belt is fastened. At the same time there will be a ringing sound from the driver information module (DIM) for the same period of time. The seat belt reminder for the front passenger will also be activated after 1 minute. There will then be a 6-second signal every 30 seconds should either the driver or the front passenger not have their seat belt fastened. Once 6 seconds have passed since the ignition was switched on, the seat belt reminder is deactivated and there is no audible signal.

American version (2009-)
All the seats in the vehicle are monitored.
Front seats:
The light symbols will light in the Driver information module (DIM) and in the lamp module in the roof if the belt is not fastened when the ignition is switched on. There is an audible signal from the driver information module (DIM) when the vehicle speed exceeds 10 km/h. This continues for 6 seconds until either the seat belt is fastened or reverse gear is selected.
Backseat:
For the rear seat there is a status monitor that generates different text messages depending on which seat belt is used. These messages go out 6 seconds after the vehicle has reached a speed greater than 10 km/h if a belt is fastened. If a belt is unfastened, the driver is alerted via text message as well as light and audible signals. The signals follow the front seat.

All messages can be switched off using the Read button on the control stalk.

Trip odometer / odometer




The function of the trip odometers and the odometer is to display the three available odometer modes. The two settings are the total mileage of the car and the mileage since the two trip odometers were last set to zero. The trip odometers can be reset individually. The odometer and one of the two trip odometers are always displayed. Press the button briefly to switch between the two trip odometers. Hold the button in longer to reset the trip odometer. The driver information module (DIM) must also be powered.
The central electronic module (CEM)(4/56) receives a speed signal from the brake control module (BCM) (4/16) which is transmitted on the high speed section of the control area network (CAN). The central electronic module (CEM) then transmits the signal on to the driver information module (DIM) (5/1) via the low speed section of the control area network (CAN). The distance traveled is saved every fourth kilometer and the value is stored in the central electronic module (CEM).

Service message





The following information applies to vehicles of model year 2008 and earlier
The service message appears the first time the ignition is switched on after the condition for servicing has been fulfilled. The service message is shown every 120 seconds (model year 2006- 240 seconds) each time the ignition is switched on until it is reset. The service message also appears 1 minute after the ignition is switched off (applies to model year 2006-). The service message consists of the text "Time for service". The condition for the service message to appear can be programmed based on three different parameters:
- mileage
- time
- engine hours.
The quality of the engine oil also has an impact on when the message is displayed. However this parameter cannot be programmed.

The following information applies to vehicles of model year 2009 and later
In order to give the car owner greater possibility of having maintenance service done at the right time, the driver is informed when it is time to book a time for maintenance service. The service message is shown before the actual conditions for the service interval are fulfilled, to avoid exceeding the service interval.

The service message is shown as a text message in the Driver information module (DIM) in the following steps:
1. Book time for service
The text message "Book time for service" is shown when any of the following conditions is fulfilled:
- 1,250 km (777 miles) before distance condition for service interval.
- 1 month before time condition for service interval.
- 100 hours before engine time condition for service interval.
1. time for service
The text message "Time for service" is shown when any of the conditions for service interval is fulfilled. The service interval is dependent on model, engine, and market, and thus it varies.
An example of condition for a service interval may be:
- Distance condition - 15,000 km.
- Time condition - 12 months.
- Engine time condition - 750 hours.
1. Time for service exceeded
The text message "Time for service exceeded" is shown when any or several of the conditions for service interval are fulfilled, and any of the following conditions is fulfilled:
- 1,250 km (777 miles) after distance condition for service interval.
- 1 month after time condition for service interval.
- 100 hours after engine time condition for service interval.
The service message continues to be shown every time the ignition is turned on, until maintenance service is done and the service message has been erased.

The conditions for showing the service message can be programmed according to three different parameters:
- Distance condition - Driving distance.
- Time condition - Number of months since last service.
- Engine time condition- Number of hours engine has been running.
The engine oil's quality also has an impact on when the service message is shown. However, this parameter cannot be programmed.

Note! The service message may vary depending on market and/or language.

Resetting the service message
The service message can be reset using VIDA or as follows:
- Turn the key to position I
- Press the reset button for the trip odometer. Turn the key to position II within two seconds
- Hold the button pressed down until the information lamp begins to flash
- Release the button.

Engine temperature gauge




The engine control module (ECM), (4/46) processes the value it receives from the engine coolant temperature (ECT) sensor. The processed value is then transmitted to the central electronic module (CEM) (4/56) on the high speed section of the control area network (CAN). The central electronic module (CEM) receives the signal and generates a corresponding signal on the low speed section of the control area network (CAN). The driver information module (5/1) reads the signal from the low speed section of the control area network (CAN). The driver receives information about the temperature from the engine coolant temperature gauge in the combined instrument panel. A red lamp lights if the value is too high. A text message with explanatory information is also displayed.

Parking brake




The sensor for the parking brake is directly connected to the central electronic module (CEM). A signal which indicates whether the parking brake is applied or not is transmitted from the sensor to the central electronic module (CEM) (4/56). The central electronic module (CEM) sends the signal on to the driver information module (DIM) (5/1) via the controller area network (CAN). When the parking brake is applied (activated) the lamp lights.
The driver information module (DIM) can be programmed so that the driver is also warned by an audible signal that the parking brake is activated.

SRS warning lamp




The supplementary restraint system (SRS) (4/9) contacts the driver information module (DIM) (5/1) if there is a problem in the system. A signal is transmitted via the control area network (CAN) and the driver information module (DIM) lights the SRS lamp and displays a text message. The driver information module (DIM) also informs the supplemental restraint system module (SRS) whether the indicator lamp is working or not. A text message is displayed and the red warning lamp lights if the SRS warning lamp is not working.

Brake warning lamp




The brake control module (BCM) (4/16) informs the driver information module (DIM) (5/1) if there is a fault in the brake system. The driver information module (DIM) informs the driver by lighting warning lamps and also displaying a text message. The signal is transmitted from the brake control module (BCM) (4/56) to the central electronic module (CEM) on the high speed section of the control area network (CAN). The central electronic module (CEM) transmits the signal onwards on the low speed section of the controller area network (CAN) to the driver information module (DIM).
The brake fluid level sensor detects the level of the brake fluid in the reservoir. The switch in the sensor closes again when the level is low. A signal is then transmitted on the controller area network (CAN) to the driver information module (DIM) which lights the red warning lamp and the brake warning lamp. The driver information module (DIM) also displays a text message.

Fuel gauge




There is sensor in the fuel tank, in some cases two. These transmit signals about the actual fuel level to the central electronic module (CEM) (4/56). The central electronic module (CEM) sends the signals on to the driver information module (DIM) (5/1). The driver information module (DIM) receives the signals, interprets them and displays the actual fuel level in the fuel gauge.
The low fuel level warning lamp lights when the fuel level is low. The warning lamp informs the driver that the fuel level is low. The warning lamp lights when there has been less than nine liters of fuel in the tank for 45 seconds.
The fuel gauge is not sensitive to rapid change. This is to prevent incorrect values being displayed when cornering or driving on slopes for example.

Speedometer




The speedometer displays the actual speed the car is traveling at.
Information about speed comes from the speed sensor which is connected to the brake control module (BCM) (4/16) and the transmission control module (TCM) (4/28). The brake control module (BCM) and the transmission control module (TCM) calculate an average speed based on the signals sent from the two front wheels by the speed sensors. The calculated speed signals are then sent to the central electronic module (CEM) (4/56) from the brake control module (BCM) and the transmission control module (TCM) on the high speed section of the controller area network (CAN). Depending on the quality of the signal, the central electronic module (CEM) uses the signal from the brake control module (BCM) or the transmission control module (TCM). The central electronic module (CEM) then sends this information on to the driver information module (DIM) (5/1) which displays the speed.
Transmission control modules (TCM) are only installed in cars with automatic transmissions. In cars with manual transmissions, the speed signal is sent to the central electronic module (CEM) only by the brake control module (BCM).

Tachometer




A flywheel sensor is connected to the engine control module (ECM) (4/46). The engine control module (ECM) transmits the engine speed on the high speed section of the control area network (CAN). The central electronic module (CEM) (4/56) receives the signal and generates a corresponding signal on the low speed section of the control area network (CAN). The driver information module (DIM) (5/1) reads the signal and displays the engine speed for the driver.

Gear Selection Indicator (GSI) (only Drive vehicles)




Engine control module (ECM) (4/46) checks the vehicle speed in relation to the current gear. The value is sent to the Central electronic module (CEM) (4/56) and on to Driver information module (DIM) (5/1).
In the lower information display in the Driver information module (DIM), an arrow appears at the most appropriate time to change up or down.

Warning lamp for low oil pressure (only applies to versions with oil pressure sensor)
The oil pressure sensor is connected to the engine control module (ECM) (4/46). The engine control module (ECM) transmits the oil pressure signal onwards via the high speed section of the control area network (CAN). The central electronic module (CEM) (4/56) receives the signal and generates a corresponding signal on the low speed section of the control area network (CAN). The driver information module (DIM) (5/1) receives the signal. If the oil pressure is low, the driver information module (DIM) lights a red warning lamp to warn the driver. Explanatory information is also displayed as a text string.

Hint: In vehicles with an oil level sensor, the general warning lamp comes on and a text message appears when the oil level is too low.
For information about whether the vehicle is equipped with an oil pressure or oil level sensor, see Design and Function, Engine control module (ECM).

General red warning lamp
This function displays different "faults" in the car. When a lamp lights this is followed by a text message that presents the driver with additional information about why the lamp has lit. The red warning lamp lights in the event of serious faults that affect driveability.

Yellow information lamp
This function displays information. When a lamp lights this is followed by a text message that presents the driver with additional information about why the lamp has lit. The yellow information lamp lights when there is information of a less serious nature.

Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) only lights in the driver information module (DIM) (5/1) if certain specific emissions related diagnostic trouble codes (DTCs) are stored in the engine control module (ECM) (4/46) or transmission control module (TCM) (4/28). A text message is also displayed when the lamp lights. The signal between the driver information module (DIM) and engine control module (ECM) is directly connected.
