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
The reduction gear fluid should be
inspected according to the intervals
specified in 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, the disc, and the
rotor for any excessive wear-out.
Inspect calipers for any fluid leakage.

The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season
and before travelling to a colder cli-
mate.Checking the coolant level
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 and the MIN
marks on the side of the coolant
reservoir when the parts in the motor
compartment is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring
the level to the MAX mark, but do not
overfill. If frequent additions are
required, we recommend that you
see a HYUNDAI authorised repairer
for a cooling system inspection.
OAEE076002L

MaintenanceThe electric motor for the cooling fan
is controlled by coolant temperature,
refrigerant pressure and vehicle
speed. As the coolant temperature
decreases, the electric motor will
automatically shut off. This is a nor-
mal condition.
Never remove the
coolant cap or the
drain plug whilst the
radiator is hot. Hot
coolant and steam
may blow out under pressure,
causing serious injury.
(Continued)
WARNING
OAEE076002
The electric motor for
the cooling fan may
continue to operate
or start up when the
vehicle is not operat-
ing and can cause serious
injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING (Continued)
Turn the vehicle off and wait
until the parts in the motor com-
partment cools down. Use
extreme care when removing
the coolant cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

Recommended coolant
When adding coolant, use onlydeionized water, distilled water or
soft water for your vehicle and
never mix hard water in the coolant
filled at the factory.
An improper coolant mixture can result in severe malfunction or
electric vehicle system damage.
Do not use alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
Make sure the coolant cap is
properly closed after refilling
coolant.
1. Check if the coolant cap label
is straight In front.

Maintenance
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 as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing coolant
We recommend that coolant be
changed by a HYUNDAI authorised
repairer according to the
Maintenance Schedule.
To prevent damage to parts in the
motor compartment, put a thick
towel around the coolant cap
before refilling the coolant to pre-
vent the coolant from overflowing
into parts in the motor compart-
ment.
NOTICE
i
Do not use coolant or antifreeze
in the washer fluid reservoir.
Coolant can severely obscure
visibility when sprayed on the
windscreen and may cause loss
of vehicle control resulting in an
accident.
Coolant may also cause dam-
age to paint and body trim.
