Test conditions/procedure:
1. All of the following conditions should be satisfied when the drive test is carried out.
(1) Engine coolant temperature: 80°C (176°F) or higher (when engine is fully warmed up)
(2) Outside air temperature: -10°C (14°F) or higher
(3) A/T condition:
- Selector lever position: D range
- Overdrive switch: ON
- Power/economy change over switch: Power
2. Carry out one trip monitoring according to the following drive pattern (from starting of the engine until ignition is turned off). (Takes approximately 5 minutes.)
*1: After the engine is fully warmed up, turn the ignition switch to OFF.
*2: Start the engine and accelerate to a speed of between 56 - 64 km/h (35 - 40 mph).
+3: Monitoring period: drive for 120 seconds or more while maintaining the throttle opening angle at a constant angle (keeping throttle variations as small as absolutely possible) and the vehicle speed at between 56 - 64 km/h (35 - 40 mph). Drive as consistently as possible during this time, without making any sudden steering wheel movements.
*4: Decelerate to a stop. After the vehicle has stopped, turn the ignition switch to OFF
