Speedometer Check

WARNING: This page is about a different car, the 2004 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.

Adjust the pressure of tires to the specified level. (Refer to TIRE INFLATION PRESSURE CHECK .)

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

Set the vehicle onto a speedometer tester and use wheel chocks to hold the rear wheels.

To prevent the front wheel from moving from side to side, attach tension bars to the tie-down hook, and secure both ends to anchor plates.
To prevent the vehicle from moving, attach a chain or wire to the rear retraction hook, and make sure the end of the chain or wire is secured.

Check if the speedometer indicator range is within the standard values.
