SPEEDOMETER
1. Adjust the pressure of the tires to the specified level.
2. Drive the vehicle onto a speedometer tester. Use wheel chocks as appropriate.

CAUTION: Do not operate the clutch suddenly or increase/decrease speed rapidly while testing.

NOTE: Tire wear and tire over or under inflation will increase the indication error.
