Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. 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 transmission
occurs, check the transmission
fluid level.
Check the dual clutch transmission
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 engine
coolant reservoir.
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 Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function. Be careful when checking your
engine coolant/inverter coolant
level when the engine is hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.

Maintenance
Recommended coolant
When adding coolant, use only
distilled (deionized) water or soft
water for your vehicle and never
mix hard water in the coolant filled
at the factory.
An incorrect coolant mixture can
result in severe malfunction or
engine/hybrid system damage.
The engine in your vehicle has alu-
minium engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.
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.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 an authorised HYUNDAI
dealer according to the Maintenance
Schedule at the beginning of this
chapter.
To prevent damage to engine parts,
put a thick towel around the engine
coolant cap and/or inverter coolant
cap before refilling the coolant to
prevent the coolant from overflow-
ing into engine parts, such as the
generator.

Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control
resulting in an accident.
Engine coolant may also cause
damage to paint and body trim.
WARNING

Maintenance
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, we
recommend that the brake system
be checked by an authorised
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 miner-
al 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.
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
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. We recommend
that the vehicle be inspected by
an authorised 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.

Maintenance
Checking the parking brake
Foot type (if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by
an authorised HYUNDAI dealer.
Stroke : 4~5 notch
Filter replacement
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.
Replace the filter according to the
Maintenance Schedule.OAE056014R

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
screen and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
Do not allow sparks or flames
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.
