1. WHEEL ARCH HEIGHT
1) Park the vehicle on a level surface.
2) Set the vehicle under "curb weight" condition.
(Make the luggage compartment empty, install the
spare tire, jack and service tools, and top up the
fuel tank.)
3) Set the steering wheel in a straight-ahead posi-
tion, and stabilize the suspensions by moving the
vehicle straight more than 5 m (16 ft).
4) Suspend a thread from wheel arch (point "A" in
the figure below) to determine the point directly
above the center of wheel.
5) Measure the distance between the point "A" and
the center of wheel.
