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
recommended for your vehicle.
Recommended cold tyre infla-
tion pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold Tyres” means
the vehicle has not been driven for at
least three hours or driven less than
1.6 km.
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For the recommended inflation
pressure refer to “Tyre and
wheels” in chapter 8.All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.Tyre underinflation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Maintenance
Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend that the tyre
be checked by an authorised
HYUNDAI dealer.
Overinflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
CAUTION
Warm tyres normally exceed
recommended cold tyre pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tyres to adjust the pres-
sure or the tyres will be
underinflated.
Be sure to reinstall the tyre
inflation valve caps. Without
the valve cap, dirt or moisture
can get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
CAUTION
Tyre pressure
Always observe the following:
Check tyre pressure when the
tyres are cold. (After vehicle
has been parked for at least
three hours or hasn't been
driven more than 1.6 km since
startup.)
Check the pressure of your
spare tyre each time you
check the pressure of other
tyres.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tyres can cause
accidents. If your tread is
badly worn, or if your tyres
have been damaged, replace
them.
CAUTION
Tyre inflation
Overinflation or underinflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure. This
could result in loss of vehicle
control and potential injury.

Maintenance
Checking tyre inflation pres-
sure
Check your tyres once a month or
more.
Also, check the tyre pressure of the
spare tyre.
How to check
Use a good quality 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 inflated even when
they're underinflated.
Check the tyre's inflation pressure
when the tyres are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km.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 amount.
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. They help prevent
leaks by keeping out dirt and mois-
ture.Inspect your tyres frequently
for proper inflation as well as
wear and damage. Always use
a tyre pressure gauge.
Tyres with too much or too lit-
tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and sudden
tyre failure leading to acci-
dents, injuries, and even
death. 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 pil-
lar.
Worn tyres can cause acci-
dents. Replace tyres that are
worn, show uneven wear, or
are damaged.
Remember to check the pres-
sure of your spare tyre.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tyres on your
vehicle.
WARNING

Maintenance
Tyre rotation
To equalize tread wear, it is recom-
mended that the tyres be rotated
every 12,000 km or sooner if irregu-
lar wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of tyre. Replace the tyre if you find
either of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring the
front and rear tyre pressures to spec-
ification and check wheel nut tight-
ness.
Refer to “Tyre and wheels” in
chapter 8.
Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of the unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a bad effect on
vehicle performance.
i
Do not use the compact spare
tyre for tyre rotation.
Do not mix bias ply and radial
ply tyres under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.

Maintenance
Wheel alignment and tyre bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Improper wheel weights can
damage your vehicle's aluminium
wheels. Use only approved wheel
weights.
Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1.6 mm of tread left
on the tyre. Replace the tyre when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.
NOTICE
OLMB073027
Tread wear indicatorWhen replacing the tyres,
recheck and tighten the wheel
nuts after driving about 1,000
km. If the steering wheel shakes
or the vehicle vibrates whilst
driving, the tyres are out of bal-
ance. Align the tyre balance. If
the problem is not solved, we
recommend that you contact an
authorised HYUNDAI dealer.
WARNING

7-58
Maintenance
Compact spare tyre replace-
ment (if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your
new vehicle and should be mounted
on the same compact spare tyre
wheel. The compact spare tyre is not
designed to be mounted on a regular
size wheel, and the compact spare
tyre wheel is not designed for mount-
ing a regular size tyre. The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
When replacing tyres (or
unwheels), it is recommended
to replace the two front or two
rear tyres (or wheels) as a
pair.
Replacing just one tyre can
seriously affect your vehicle's
handling.
The ABS works by comparing
the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all 4
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.Driving on worn-out tyres is
very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
Your vehicle is equipped with
tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tyre and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tyre maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removed
from the wheel.
Tyre sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tyre and also provides
the tyre identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tyre in
case of a recall.
