Steering
Steering Wheel Rotational Play
Check
1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel
left and right without moving the front wheels.
. lf the play is within the limit, the gearbox and
linkage are OK.. lf the playexceedsthe limit, adjustthe rack guide
{see page '17-13). lf the play is still excessive after
rack guide adjustment, inspect the steering
linkage and gearbox {see page 17-5).
BOTATIONAL PLAY: 0 10 mm (0-0.39 in.l

Power Assist Check
Start the engine, and let it idle.
Attach a commercially available spring scale to the
steering wheel. With the engine idling and the
vehicle on a clean, dry floor, pull the scale as
shown, and read it as soon as the tires begin to turn.
\
1.
3. lf the scale reads no morethan 29 N (3.0 kgf,6.6 lbf),
the power assist is OK. lf it reads more, check these
items:
. Front tire pressure. Steering linkage (see page 17-5). Rack gulde adjustment (see page 17-13). EPS system (see page 17-18)

Front and Rear Suspension
WheelAlignment
The suspension can be adjusted for front camber, front
toe, and rear toe. However, each of these adjustments
are interrelated to each other. For example, when you
adjust the toe, the camber changes. Therefore, you
must adjust the front wheel alignment whenever you
adjust the camber or toe.
Pre-Alignment Checks
For proper inspection and adjustment of the wheel
alignment, do these checks:
1. Release the parking brake to avoid an incorrect
measurement.
Make sure the suspension is not modified.
Check the tire size and tire pressure
Tire size:
Front/rear: 195/60R15
Tire pressure:
Front: 230 kPa {2.3 kgf/cm',33 psil
Rear: 210 kPa |'2.1 kgf/cm', 30 psi)
Check the runout of the wheels and tires.
Check the suspension ball joints. (Hold a wheel
with your hands, and move it up and down and
right and left to check for wobbling),
2.
3.
Bounce the vehicle up and down several times to
stabilize the suspension.

Front Caster lnspection
Use commerciallv available comDuterized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
eouioment manufacturer's instructions.
Check the caster angle. lf the caster angle is not within
the specification, check for bent or damaged
susoensron comoonents.
Front caster angle: 1'40't 1"

ABS Gomponents
System Description (cont'd)
Features
When the brake pedal is pressed during driving, the wheels can lock before the vehicle comes to a stop. In such an
event. the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is
reduced if the rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip
rate of the wheels to ensure maximum grip force from the tires, thereby ensuring the maneuverability and stability of
the vehicle.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed, then it controls the
brake fluid pressure to reach the target slip rate.

Exterior Lights
Headlight Adjustment
Before adiusting the headlights:. Park the vehicle on a level surface.. Make sure the tire pressures are correct.. The driver or someone who weighs the same should
sit in the driver's seat.
'1. Clean the outer lens so that you can see the center
of the headlights (A).
Headlights become very hot during use; do not
touch them or any attaching hardware immediately
after they have been turned off.

2. Park the vehicle 7.5 m (25 ft) away from a wall or a
screen (A).
3. Open the hood.
