If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure Telltale/
TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds when the ignition switch
is placed to the ON position or
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure Position
Telltale remains illuminated.
Low tire pressure
telltale
Low tire pressure position and
tire pressure telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and a warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-
cate which tire is significantly under-
inflated by illuminating the corre-
sponding position light.If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
10 minutes at speed above 25 km/h
(15.5 mph)) until you have the low
pressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.

Maintenance
OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorized
HYUNDAI dealer at the frequencies
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 labor, 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 an author-
ized HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance 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 tires (front and back)
to prevent the vehicle from
moving.
Remove loose clothing or jew-
elry 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 the
engine coolant reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated
tires.
While 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 traveling 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
tires including the spare for tires
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 windshield 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.
