What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre should be checked month-
ly when cold and inflated to the infla-
tion pressure recommended by the
vehicle manufacturer on the vehicle
placard or tyre inflation pressure
label. (If your vehicle has tyres of a
different size than the size indicated
on the vehicle placard or tyre infla-
tion pressure label, you should deter-
mine the proper tyre inflation pres-
sure 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 effi-
ciency and tyre tread life, and may
affect the vehicle’s handling 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-
sure, 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 illu-
minated, the system may not be able
to detect or signal low tyre pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, includ-
ing the installation of replacement or
alternate tyres or wheels on the vehi-
cle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or alter-
nate tyres and wheels allow the
TPMS to continue to function proper-
ly.
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.

Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
(Continued)Replace tyres that are worn,
show uneven wear, or are dam-
aged. Worn tyres can cause
loss of braking effectiveness,
steering control, or traction.
ALWAYS replace tyres with
the same size as each tyre
that was originally supplied
with this vehicle. Using tyres
and wheels other than the rec-
ommended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tyre failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tyres monthly for
proper inflation as well as
wear and damage.
The recommended cold tyre
pressure for your vehicle can
be found in this manual and on
the tyre label located on the
driver’s side centre pillar.
Always use a tyre pressure
gauge to measure tyre pres-
sure. Tyres with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the
spare every time you check
the pressure of the other tyres
on your vehicle.

Maintenance
Check tyre inflation pressure
Check your tyres, including the spare
tyre, once a month or more.
How to check
Use a good quality tyre pressure
gauge to check tyre pressure. You
can not tell if your tyres are properly
inflated simply by looking at them.
Radial tyres may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyre
inflation pressure matches the rec-
ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reach
the recommended pressure. Make
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.If you overfill the tyre, release air by
pushing on the metal stem in the
centre of the tyre valve. Recheck the
tyre pressure with the tyre gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend it be checked
by a HYUNDAI authorised
repairer.
Over-inflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
