Maintenance

Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Power steering pump, belt and
hoses
Check the power steering pump and
hoses for leakage and damage.
Replace any damaged or leaking
parts immediately. Inspect the power
steering belt (or drive belt) for evi-
dence of cuts, cracks, excessive
wear, oiliness and proper tension.
Replace or adjust it if necessary.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
(if equipped)
Check the air conditioning lines and
connections for leakage and dam-
age.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the Hyundai web site.

Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.

POWER STEERING FLUID
Checking the power steering
fluid level
With the vehicle on level ground,
check the fluid level in the power
steering reservoir periodically. The
fluid should be between MAX and
MIN marks on the side of the gauge
at the normal temperature.Before adding power steering fluid,
thoroughly clean the area around the
reservoir cap to prevent power steer-
ing fluid contamination.
If the level is low, add fluid to the
MAX level.
In the event the power steering sys-
tem requires frequent addition of
fluid, we recommend that the system
be inspected by an authorized
HYUNDAI dealer.
Use only the specified power steer-
ing fluid. (Refer to "Recommended
lubricants or capacities" in section
8.)
CAUTION
• To avoid damage to the power
steering water pump unit, do
not operate the vehicle for
prolonged periods with a low
power steering fluid level.
• Never start the engine when
the reservoir tank is empty.
• When adding fluid, be careful
that dirt does not get into the
tank.
• Too little fluid can result in
increased steering effort
and/or noise from the power
steering system.
• The use of the non-specified
fluid could reduce the effective-
ness of the power steering sys-
tem and cause damage to it.

Checking the power steering
hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
WARNING- Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.
• Windshield Washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
• Windshield washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury or
death could occur.

WARNING- Replacing
tires
To reduce the chance or serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
• Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
• Do not drive your vehicle with
too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
• When replacing tires, never
mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.
(Continued)
(Continued)
• Using tires and wheel other
than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-
ous accident.
• Wheels that do not meet
HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
• The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) to work irregularly.CAUTION
When replacing the tires,
recheck and tighten the wheel
nuts after driving about 1,000
km (620 miles). If the steering
wheel shakes or the vehicle
vibrates while driving, the tire is
out of balance. Align the tire bal-
ance. If the problem is not
solved, we recommend that you
contact an authorized HYUNDAI
dealer.
