• Carry out test in very little traffic area to prevent an accident.
• Test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift select “D”.
3) Accelerate vehicle speed by depressing accelerator pedal gradually.
4) While driving in “D” range, check if gear shift and lock-up occur properly as shown in “Automatic Gear Shift
Diagram”.
