If any of the below happens, have
the system checked by an autho-
rised HYUNDAI dealer.
1. The Low Tyre 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 Tyre Pressure Position
Telltale remains illuminated.
Low tyre pressure
telltale
Low tyre pressure position and
tyre pressure telltale
When the tyre pressure monitoring
system warning indicators are illumi-
nated and a warning message dis-
played on the cluster LCD display,
one or more of your tyres is signifi-
cantly under-inflated. The Low Tyre
Pressure Position Telltale will indi-
cate which tyre 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 tyres as soon as pos-
sible. Inflate the tyres to the proper
pressure as indicated on the vehi-
cle’s placard or tyre inflation pres-
sure label located on the driver’s side
centre pillar outer panel.
If you cannot reach a service station
or if the tyre cannot hold the newly
added air, replace the low pressure
tyre with the spare tyre.
The Low Tyre 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 tyre repaired and replaced
on the vehicle.

The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorised
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 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 an autho-
rised 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 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 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.
WARNING
