What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tyre inflation pressure label. If
your vehicle has tyres of a different
size than the size indicated on the
vehicle placard or tyre inflation pres-
sure label, you should determine the
proper tyre inflation pressure for
those tyres.As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is significantly under-
inflated. Accordingly, when the low
tyre pressure telltale illuminates, you
should stop and check your tyres as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure. Under-inflation also
reduces fuel efficiency and tyre tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tyre mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sures, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tyre pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tyre pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
native tyres or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tyres or wheels on your
vehicle to ensure that the replace-
ment or alternative tyres and wheels
allow the TPMS to continue to func-
tion properly.

Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
may cause loss of vehicle con-
trol resulting in an accident.

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. 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, we recommend that the
system be serviced by an
authorised HYUNDAI dealer.
ALWAYS follow these precau-
tions for performing mainte-
nance work:
Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transmission/dual clutch
transmission vehicle) posi-
tion, apply the parking brake,
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-
ellry that could become entan-
gled in moving parts.WARNING If you must run the engine
during maintenance, do so
outdoors 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 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 a smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or a “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmis-
sion/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). Be careful when checking your
engine 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
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pres-
sure pump, high-pressure
pipes, rail, and injectors are still
subject to the high pressure
right after stopping the diesel
engine. When the fuel leakage
vents out, it may cause serious
body injury. Any people, who
are implemented with the artifi-
cial cardiac pacemaker, should
remain away from the ECU or
the wiring harness by at least 30
cm, whilst running the diesel
engine. The high currents of the
electric engine control system
produce a considerable amount
of magnetic fields.
