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.
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side centre pillar. (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
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.
Warm tyres normally exceed recom-
mended cold tyre pressures 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 under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tyre and Wheels” in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tyre wear.
Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation 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 resulting in an accident.
This risk is much higher on hot
days and when driving for long
periods at high speeds.
WARNING
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 an authorised HYUNDAI
dealer.
Over-inflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
CAUTION

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.
Tyre rotation
To equalise tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 10,000 km or sooner if
irregular 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 pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of the tyre.
Replace the tyre if you find any 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 specification and check
lug nut tightness (proper torque is
11~13 kgf·m).

7-50
Maintenance
Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of an unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" facing the outside. If the side
marked "inside" is installed on the
outside, it will have a negative effect
on vehicle performance.
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.
Incorrect wheel weights can dam-
age your vehicle’s aluminium
wheels. Use only approved wheel
weights.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
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 may cause loss of
vehicle control resulting in an
accident.

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.When replacing the tyres, recheck
and tighten the wheel nuts after
driving about 620 mile. If the steer-
ing wheel shakes or the vehicle
vibrates while driving, the tyre is
out of balance. Align the tyre bal-
ance. If the problem is not solved,
we recommend that you contact
an authorised HYUNDAI dealer.
NOTICE
OLMB073027
Tread wear indicatorTo reduce the risk of DEATH or
SERIOUS INJURY:
Replace tyres that are worn,
show uneven wear, or are
damaged. Worn tyres can
cause loss of braking effec-
tiveness, steering control, and
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 recom-
mended 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.
(Continued)
WARNING

7-52
Maintenance
(Continued)
When replacing tyres (or
wheels), 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 vehi-
cle’s handling.
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tyres be replaced after six
(6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning may cause sudden
tyre failure, which could lead
to a loss of vehicle control
resulting in an accident.
Replacing tyres
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 form 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 tires, be sure to equipped
all four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capability.
(Continued)
(Continued)
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.
It is best to replace all four
tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.
Replacing just one tire 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.

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.
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. The original tyre should be
repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle control
resulting in an accident. The com-
pact spare tyre is for emergency
use only. Do not operate your
vehicle over 80 km/h when using
the compact spare tyre.
WARNING
(Continued)
For replacement with an
unsymmetrical tyre, you
should check the
outside/inside of the unsym-
metrical tyre. Make sure that
the outside mark should
locate in the outward direc-
tion. If not, it may adversely
affect vehicle performance,
riding comfort, and tyre worn-
out rates.
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tyre clearance, snow
chain clearance, speedometer
and odometer calibration, head-
lamp aim and bumper height.

Maintenance
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 labelling
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.
1. Manufacturer or brand name
Manufacturer or brand name is
shown.
2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this
information when selecting replace-
ment tyres for your vehicle. The fol-
lowing explains what the letters and
numbers in the tyre size designation
mean.Example tyre size designation:
