The difference between both sides should be
within 0.6 kg.Park the vehicle on a paved and flat ground
and place the front wheels at straight ahead
direction.
Start the engine and let it run around 1,000
rpm.
Install the spring scale on the circumference o
f
the steering wheel and measure the steering
effort in both directions. 1.

3. Steering Effort Check ▶
Steering Angle Check ▶
Place the front wheel on a turning radius
measuring tool.
Turn the steering wheel to the its both ends
and measure the maximum steering angle. 1.
2.
If the steering angle is out of the specified
value, check and adjust the toe-in.
Steering angleInner36.2˚
Outer32.4˚
Free Play Check ▶
Start the engine and place the wheels at
straight ahead direction.
Turn the steering wheel until the tires starts to
move and measure the distance on the
circumference of the steering wheel. 1.
2.
If the free play is out of the specified value,
check the free play in steering column shaft
connection and steering linkage. Replace or
repair if necessary.

Oil Change ▶
Open the power fluid reservoir cap and drain
the fluid completely with oil suction device. To
make it easy, turn the steering wheel to its
both ends several times.
Fill up the specified fluid into fluid reservoir
and bleed air from the steering system. 1.
2. Oil Level Check ▶
Place the vehicle on a level ground and start
the engine and let it run at idle speed.
Turn the steering wheel several times so that
the oil temperature reaches to normal
operating level (75~85˚C).
Place the steering wheel at straight ahead
direction.
Check the oil level in the power steering oil
reservoir. Adjust the oil level between MAX
and MIN. 1.

If the difference between two measurements
is below 5 mm and the level is between MAX
and MIN level, it's normal. If it is over 5 mm,
bleed air from the system. Check the fluid level on a level ground with the
engine turned off. The fluid level should be
between the MIN and MAX marks on the
reservoir cap gauge.
