Road TestS7RS0B5104011
This test is to check if upshift, downshift and lock-up take place at specified speeds while actually driving vehicle on a
level road.
WARNING!
• 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 lever “D” range.
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 Table”.
