Initial Learning

Warning:
^ When performing initial learning, be aware of other vehicles, people, and other impediments in order to avoid an accident.


Note:
^ While self-learning control gradually reduces shock during normal driving, initial learning is performed to initially learn a certain amount of driving conditions.

1. Warm-up
^ Increase the ATF temperature by leaving the vehicle idling or performing city driving. Verify that the ATF temperature is between 66 - 110° C (151 - 230° F). If the ATF temperature is outside this range, work to bring it inside the range.

Caution:
^ Do not raise the ATF temperature by stalling the engine.


Note:
^ If the ATF temperature is not between 66 - 110° C (151 - 230° F), initial learning cannot be performed. Before learning, inspect for variable shift shock.

2. Garage shift learning
^ With the vehicle standing still, depress the brake pedal and keep the selector lever in N position for 3 s. Then, shift the selector lever from the N position into D range, and maintain in this condition for 3 s. Repeat this procedure 5 times. Then repeat it 5 times in the same way for R position.

3. Gear shift control learning
^ In D range, with the accelerator opening between 25 - 30%, drive until you reach 6th gear and a vehicle speed of 80 km/h (50 mph) or higher. Then, release the accelerator pedal and coast, and bring the vehicle to a stop in at least 60 s. Repeat this procedure 10 times.

4. Inspect learning results
^ Verify that variable speed shock and shift shock have decreased compared to the conditions before learning.
