Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction Gear Fluid
Inspect the reduction gear fluid
according to the maintenance sched-
ule.
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 the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension Mounting Bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the
vehicle off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. Check
the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts.
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
Check the air conditioning lines and
connections for leakage and dam-
age.

Checking the Brake Fluid
Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized HYUNDAI dealer. Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
Brake fluid, which has been
exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Do not use the wrong kind of
brake fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.
