The following lists are vehicle checks
and inspections that should be per-
formed by the owner or a HYUNDAI
authorised repairer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labour, parts and lubricants used.
How to Disconnect the (-)
Cable for Regular Maintenance
When the vehicle is under regular
maintenance, make sure to separate
the (-) cable before maintenance.
Separate the (-) cable following the
below instructions.
1. Fold the rear left side seat.
2. Remove the service cover (A) on
the luggage trim.
3. Separate the (-) cable (B).
Reassemble in the reverse order.
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, move the shift lever
into the P (Park) position,
apply the parking brake and
place the ignition switch in
the LOCK/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.
(Continued)
WARNING (Continued)
If you must run the engine
during maintenance, do so
out doors or in an area with
plenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in theengine 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 ofthe 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 enginecoolant 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.

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

Checking the engine oil level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the hybrid system off and wait about five minutes for the oil
to return to the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully. 6. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low).
7. If it is near or at L, add enough oil to bring the level to F. To prevent damage to your engine:
Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
Do not spill engine oil when adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.

Checking the hybrid starter &
generator (HSG) belt
We recommend that you have the
hybrid starter & generator (HSG)
belt inspected or replaced according
to the Maintenance Schedule by a
HYUNDAI authorised repairer.
Checking the brake fluid level
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 thor-
oughly to prevent brake fluid contam-
ination.
Turn the vehicle off whilst you
inspect the engine or hybrid
starter & generator(HSG) belt.
Otherwise it may result in
serious injury.
Keep hands, clothing etc.
away from the hybrid starter &
generator (HSG) belt.
WARNING
When the HSG belt is worn out or
damaged, replace the belt.
Otherwise, it may cause engine
overheating or battery discharge.
