Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Gear Fluid
The gear fluid should be inspected and
replaced according to the intervals
specified in the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the 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 conforming to DOT 4
specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads, the discs, and the rotors
for any excessive wear-out. Inspect
calipers for any 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.

Coolant
B9001901
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled between
the MAX or F and the MIN or L marks on
the side of the coolant reservoir when the
parts in the motor compartment is cool.
If the coolant level is low, have the vehicle
inspected by an authorized HYUNDAI
dealer.
WARNING
Keep hands, clothing, and tools away
from the rotating fan blades of the
cooling fan. The cooling fan may continue
to operate even though the vehicle is
turned off and can cause serious injury.
The electric motor for the cooling fan is
controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off.
Recommended coolant
• When adding coolant, use only deionized water, distilled water, or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.
• An incorrect coolant mixture may result in severe malfunction or motor
damage.
• Do not use alcohol or methanol coolant or mix them with the specified coolant.
• Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which could reduce the
effectiveness of the solution.
For mixing percentage, refer to the
following table:
Information If in doubt about the mix ratio, a 50 % water
and 50 % antifreeze mix is the easiest to mix
together because it is the same quantity for
each.

Brake Fluid
Checking the Brake Fluid
Level
B9002301
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 thoroughly to prevent
brake fluid contamination.
If the level is low, add the specified brake
fluid to the MAX level. If the fluid level is
excessively low or frequent additions are
required have the brake system inspected
by an authorized HYUNDAI dealer.
WARNING 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.

Washer Fluid
Checking the Washer Fluid
Level
B9002701
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use coolant or antifreeze in the washer fluid reservoir. Coolant can
severely obscure visibility when
sprayed on the windshield and may
cause loss of vehicle control resulting in
an accident or damage to paint and
body trim.
• Do not allow sparks or flame to contact the washer fluid or the washer fluid
reservoir. Washer fluid may contain
alcohol and can be flammable.
• Do not drink washer fluid and avoid contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from children and animals.
