Maintenance
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 flash-
ers.

function.
At least once a year:
Clean body and door drain holes.

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.

4. Tyre ply composition and
material
The number of layers or plies of rub-
ber-coated fabric are in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means restrained-bias ply
construction.
5. Maximum permissible infla-
tion pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded
100.
The relative performance of tyres
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
because of variations in driving
habits, service practices and differ-
ences in road characteristics and cli-
mate.
These grades are molded on the
side-walls of passenger vehicle
tyres. The tyres available as standard
or optional equipment on your vehi-
cles may vary with respect to grade.

When replacing tyres, use the same size originally supplied with the vehicle.
Using tyres of a different size can damage the related parts or make it work irregularly.

It is permissible to add 3 psi to the standard tyre pressure specification if colder temperatures are expect-
ed soon. Tyres typically loose 1 psi (7 kPa) for every 7°C temperature drop. If extreme temperature varia-
tions are expected, recheck your tyre pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you
plan to drive a high-altitude area, check the tyre pressures in advance. If necessary, inflate them to a prop-
er level. (Air inflation per altitude : +10 kPa/1 km)
