Cruise Test — Part 1
1.CHECK STARTING GEAR (D1 ) POSITION
1. Drive vehicle for approx. 10 minutes to warm engine oil and ATF up to operating
temperature.
2. Park vehicle on flat surface.
3. Set overdrive control switch to “ON” position.
4. Move selector lever to “P” position.
5. Start engine.
6. Move selector lever to “D” position.
7. Accelerate vehicle by constantly depressing accelerator pedal
halfway.
8. Does vehicle start from D
1 ?
Read gear position.
