Driver/Vehicle Information Display: Description and Operation

OVERHEAD TRAVEL INFORMATION SYSTEM (OTIS)/HOMELINK
The Overhead Travel Information System (OTIS) gives the driver information that supplements the primary gauge instrumentation. OTIS displays this information on a Vacuum Fluorescent Display (VFD). The OTIS module has four switch inputs. The buttons for these switches are integral to the OTIS housing. There are two buttons on each side of the OTIS. The buttons are labeled US/M, C/T; STEP and RESET. The driver selects and resets display functions through the use of these four buttons. The OTIS will display these functions:
Compass/Temperature
AVE ECO Average Fuel Economy
ECO Instantaneous Fuel Economy
DTE Distance to Empty
ET Elapsed Time
ODO Trip Odometer

If the vehicle is equipped with the optional Homelink feature, the OTIS will have three buttons located in the center of the OTIS module. The OTIS module receives all of its information over the PCI bus except compass, which is internal to the OTIS module. The OTIS powers up when it recognizes vehicle voltage on the ignition input circuit. OTIS blanks the display, then illuminates all segments of the VFD. It then blanks the display again. During this time, the OTIS sends and receives information over the PCI bus to determine what to display after the two-second initialization. The OTIS displays dashes -- - -) for any of the screens for which it did not receive bus messages during the two-second initialization. These dashes will be replaced by valid information if and when it is received from the bus.

Electronic Vehicle Information Center (EVIC)
A new overhead console (EVIC), on models equipped with this option, combines features of the Overhead Travel Information System (OTIS) into an Electronic Vehicle Information Center (EVIC). The Electronic Vehicle Information Center includes a unique interface that allows customers to program operation of several electronic features to suit their individual preferences. The EVIC may also include the HomeLink(R) universal remote transceiver.

A blue-green vacuum-fluorescent 80 x 16 dot matrix screen displays the information. The screen also displays a vehicle icon that is used for door ajar indications and to show if a turn signal has been left ON. The console also houses courtesy/reading lamps.

Vehicle Information Display
The Vehicle Information Center provides the following functions:
- Compass direction
- Current outside temperature
- Elapsed time
- Miles/kilometers to empty
- Average fuel economy
- Instantaneous fuel economy
- Trip odometer (ODO)
- Miles/kilometers to service
- Blank screen
- Warning messages:
- TURN SIGNALS ON (with vehicle icon)
- PERFORMANCE SERVICE
- DOOR AJAR (one or more, with vehicle icon)
- WASHER FLUID LOW (with graphic)

The appearance of warning messages is accompanied by a beep.

All of the information required by the EVIC is transmitted over the PCI bus from the BCM or PCM.

Vehicle Icon Displayed Ajar Messages
The BCM and the door modules monitor all door switches and broadcasts a PCI bus status message to the EVIC. If a door is opened or closed the EVIC responds by changing the appropriate icon and message. The door icons and messages will not update if the EVIC cannot detect the bus message. If the car is moving at critical speed and any door is open, the appropriate message and icon will be displayed. A beep request will be generated when critical speed is reached for the first time.

Programmable Features
For each programmable feature, pressing the MENU button selects the menu of programmable features, which always begins with Language. Pressing the STEP button cycles the available choices. Continued pressing of the MENU button accepts the new choice and selects successive features for possible programming/reprogramming. Pressing the C/T (compass-temperature display selector) button returns the display to the normal (compass temperature display) mode. When the sequence is complete, the display also returns to the normal mode. Features that are dependent on vehicle equipment; such as REMOTE LINKED TO MEMORY, EASY EXIT, only appear if applicable.

- Customer Programmable Features:
- LANGUAGE?

The Driver may select English, Francaise, Deutsch, Italiana, Espanol. The word Language is always in English regardless of which language is selected. All other display nomenclature, including the trip computer functions, appears in the selected language.

- DISPLAY US OR METRIC?
Toggles the trip computer temperature, fuel economy, and odometer display readings between the two sets of units. It also changes the odometer display in the instrument cluster.

- AUTO DOOR LOCKS?
When this feature is selected, all doors lock automatically when vehicle speed reaches 15 mph (25 km/h). Previously this feature could be programmed only by a dealer.

- AUTO UNLOCK ON EXIT?
When automatic locking is chosen, automatic unlocking may also be selected. When selected, all doors will unlock when the driver's door is open if the vehicle is stopped and the transmission is in Park or Neutral.

- REMOTE UNLOCK?
The driver may choose to have all the doors unlock at the first press of the unlock button, or unlock only the driver's door on the first press and require a second press to unlock all doors.

- REMOTE LINKED TO MEMORY?
When chosen, the Memory System will select memorized seat, mirror and radio settings when an RKE (remote keyless entry) transmitter unlock button is pressed. If not chosen, selection of memorized settings may still be done using the memory buttons.

- FLASH LAMP ON LOCK/UNLOCK?
If enabled, front and rear turn signal lamps will flash once when the doors are locked, and twice when the doors are unlocked using the RKE transmitter. This feature may be selected with or without SOUND HORN ON LOCK?

- HEAD LAMP DELAY
The driver may choose to have the head lamps remain ON, when leaving the vehicle, for 30 seconds, 60 seconds, 90 seconds or not at all.

- HEAD LAMPS ON WITH WIPERS?
On vehicles with the automatic head lamps, the driver may choose to have the head lamps turn ON simultaneously with the windshield wipers. If the head lamps were turned ON in this way, they will also turn OFF the wipers.

- SERVICE INTERVAL
This feature selects an interval from 2000 to 7500 miles (3200 to 12,000 kilometers) in 500 mile (800 kilometer) increments between PERFORM SERVICE alert messages. When service has been performed, the counter is reset by pressing and holding the RESET button for 3 seconds as before.

- RESET SERVICE DISTANCE?
IF SERVICE INTERVAL is changed, this message asks if the accumulated service distance should be reset to 0 because the service was performed.

- EASY EXIT SEAT?
If enabled, the driver's seat moves rearward two inches (55 mm) (or to the farthest rearward position, if this is less) when the key is removed from the ignition switch to facilitate driver exit from the vehicle. If the REMOTE LINKED TO MEMORY feature is enabled, the seat will return to the memorized position when the RKE unlock button is pressed.

- TILT MIRRORS DOWN?
This programmable feature only applies to vehicles equipped with the optional memory system. The options include Yes and No. The default is No. When Yes is selected, and the vehicle is placed in reverse, the exterior mirrors tilt down towards the ground. Once reverse is disengaged, the exterior mirrors will return to their original position.

- TRAIN REMOTE?
The options include Yes and No. The default is No. When Yes is selected and the MENU button is pressed: a chime will sound and the EVIC will display "PRESS REMOTE LOCK & UNLOCK THEN PRESS UNLOCK". You have approximately 30 seconds to train up to 4 remote key fobs: after each remote key fob is trained a chime will sound indicating that the EVIC has received the training sequence. When you have finished training the remote key fobs, press the Menu button again and the EVIC will display "TRAIN DONE, x TRAINED". If no remote key fobs are pressed within approximately 30 seconds the EVIC will display "TRAIN TIMEOUT".

Memory Messages
- MEMORY #X POSITION SET (X -1 OR 2)
This message appears when the Memory System is programmed. It is accompanied by a chime tone.

- MEMORY SYSTEM DISABLED
This message appears when the driver presses a memory button or the RKE unlock button with the seat belt fastened, and/or the vehicle moving to notify the driver why memory action did not occur.
