NOTE:

When left and right wheels are adjusted for toe-in at the
same time, moving one scale graduation changes toe-in by
approximately 4 mm (0.16 in).

Turn adjusting wheel and adjusting bolt equally in oppo-
site directions so that same scale graduations are posi-
tioned directly above center of the adjusting bolt.
3) Tighten self-locking nut.
Tightening torque:
137±20 N⋅m (14±2 kg-m, 101±14 ft-lb)

5. REAR WHEEL TOE-IN (AWD MODEL)

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

Adjustment
1) Loosen self-locking nut on inner side of rear lateral link.
CAUTION:

When loosening or tightening adjusting bolt, hold
bolt head and turn self-locking nut.

Discard loosened self-locking nut and replace with a
new one.

tion.

6. THRUST ANGLE

Inspection
1) Position vehicle on a level surface.
2) Move vehicle 3 to 4 meters directly forward.
3) Determine locus of both front and rear axles.
4) Measure distance“L”between center line of loci of the
axles.
<For reference>
Thrust angle is less than 20’when“L”is equal to or less
than 15 mm (0.59 in).

Adjustment
Make thrust angle adjustments by turning toe-in adjusting
bolts of rear suspension equally in the same direction.
NOTE:
On FWD models, turn adjusting wheels one by one, by the
some amount in the opposite direction of the adjusting
bolts.
<For reference>
When one rear wheel is adjusted in a toe-in direction,
adjust the other rear wheel equally in toe-out direction, in
order to make thrust angle adjustment.
When left and right adjusting bolts are turned incremen-
tally by one graduation in the same direction, the thrust
angle of the AWD model will change approximately 10’[“L”
is almost equal to 7.5 mm (0.295 in)] and the thrust angle
of the FWD model will change approximately 12’[“L”is
almost equal to 9 mm (0.35 in)].
Thrust angle:
0°±20′
B4M0193A
NOTE:
Thrust angle refers to a mean value of left and right rear
wheel toe angles in relation to vehicle body center line.
Vehicle is driven straight in the thrust angle direction while
swinging in the oblique direction depending on the degree
of the mean thrust angle.
B4M0194A
Thrust angle: r
r=αβ2
α: Right rear wheel toe angle
β: Left rear wheel toe angle
NOTE:
Here, use only positive toe-in values from each wheel to
substitute forαandβin the equation.

7. STEERING ANGLE

Inspection
1) Place vehicle on a turning radius gauge.
2) While depressing brake pedal, turn steering wheel fully
to the left and right. With steering wheel held at each fully
turned position, measure both the inner and outer wheel
steering angle.
Steering angle:
Inner wheel 37.6°±1.5°
Outer wheel 32.6°±1.5°
G4M0482

Adjustment
Turn tie-rod to adjust steering angle of both inner and outer
wheels.
CAUTION:

Check toe-in.

Correct boot if it is twisted.
