Explanation of Scheduled
Maintenance Items
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 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.
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 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.
