What to do in an emergency
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift to P (Park) and set the park- ing brake. If the air conditioning is
on, turn it off.
3. If coolant is running out under the vehicle or steam is coming out
from the bonnet, stop the vehicle.
Do not open the bonnet until the
coolant has stopped running or
the steaming has stopped. If there
is no visible loss of coolant and no
steam, leave the vehicle running
and check to be sure the cooling
fan is operating. If the fan is not
running, turn the vehicle off.
4. Check for coolant leaking from the radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop). 5. If coolant is leaking out, turn off
the vehicle immediately and we
recommend that you call a
HYUNDAI authorised repairer for
assistance.
6. If you cannot find the cause of the overheating, wait until the radiator
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark. 7. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call a
HYUNDAI authorised repairer for
assistance.
Serious loss of coolant indi- cates there is a leak in the cool-
ing system and we recommend
that the system be checked by a
HYUNDAI authorised repairer.
When overheating from low coolant, suddenly adding coolant
may cause damages in the motor
compartments. To prevent dam-
age, add coolant slowly in small
quantities.

Check for low or under-inflated tyres.
Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by a
HYUNDAI authorised repairer.
ALWAYS follow these precau-
tions for performing mainte-
nance work:
Park your vehicle on level
ground, shift to P (Park) posi-
tion, apply the parking brake,
place the POWER button in
the OFF position.
Block the tyres (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
ellery that can become entan-
gled in moving parts.

ing materials away from the
battery related parts.
WARNING
Be careful when checking your
coolant level when the parts in
the motor compartment are hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.

Maintenance
Whilst operating your vehicle:
Check for vibrations in the steeringwheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when travelling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your reduction gear
occurs, check the reduction gear
fluid level.
Check the reduction gear P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the coolantreservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Fall)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
Check headlamp alignment.
Check the seat belts for wear and function.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and bonnethinges.
Lubricate door and bonnet locks and latches.
Lubricate door rubber weather strips.
Check the air conditioning system.
Inspect and lubricate reduction gear linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

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.

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.

Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if wash-
er fluid is not available. However, use
washer solvent with antifreeze char-
acteristics in cold climates to prevent
freezing.
OAEE076004
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 severe-
ly obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control resulting in an acci-
dent 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 flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.
