1) Adjust tire pressure to specifications.
2) Set vehicle under “curb weight”conditions. (Empty luggage compartment, install spare tire, jack, ser-
vice tools, and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point “A”in figure below) to determine a point directly above center
of spindle.
5) Measure distance between measuring point “A”and center of spindle.

쐌Inspection
1) Place front wheel on turning radius gauge.
Make sure ground contacting surfaces of front and
rear wheels are set at the same height.
2) Set ST into the center of the wheel, and then
install the wheel alignment gauge.

쐌Front Camber Adjustment
1) Loosen two self-locking nuts located at lower
front portion of strut.
CAUTION:
쐌When adjusting bolt needs to be loosened or
tightened, hold its head with a wrench and turn
self-locking nut.
쐌Discard loosened self-locking nut and
replace with a new one.
쐌When performing toe-in adjustment, align as
close to 0 mm (0 in) as possible.
2) Turn camber adjusting bolt so that camber is
set at the specification.
NOTE:
Moving the adjusting bolt by one scale graduation
changes camber by approximately 0°10′.

4. FRONT WHEEL TOE-IN S202116A1004
쐌Inspection
1) Using a toe gauge, measure front wheel toe-in.
Toe-in:
0±3mm(0±0.12 in)
2) Mark rear sides of left and right tires at height
corresponding to center of spindles and measure
distance “A”between marks.
3) Move vehicle forward so that marks line up with
front sides at height corresponding to center of
spindles.
4) Measure distance “B”between left and right
marks. Toe-in can then be obtained by the follow-
ing equation:
A−B = Toe-in
