More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimise winter driving problem,
you should follow these suggestions: Snowy or icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tyres or to
install tyre chains on your tyres. If snow
tyres are needed, it is necessary to
select tyres equivalent in size and type of
the original equipment tyres. Failure to do
so may adversely affect the safety and
handling of your car. Furthermore,
speeding, rapid acceleration, sudden
brake applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient distance between the vehicle in
operation in front and your vehicle. Also,
apply the brake gently. It should be notedthat installing tyre chains on the tyre will
provide a greater driving force, but will
not prevent side skids.
✽✽
NOTICE
Tyre chains are not legal in all countries.
Check the country laws before fitting
tyre chains.
Snow tyres
If you mount snow tyres on your vehicle,
make sure they are radial tyres of the
same size and load range as the original
tyres. Mount snow tyres on all four
wheels to balance your vehicle’s han-
dling in all weather conditions. Keep in
mind that the traction provided by snow
tyres on dry roads may not be as high as
your vehicle's original equipment tyres.
You should drive cautiously even when
the roads are clear. Check with the tyre
dealer for maximum speed recommen-
dations.
Do not install studded tyres without first checking local, state and municipal regu-lations for possible restrictions against their use.
WINTER DRIVING
WARNING - Snow tyre size
Snow tyres should be equivalent in
size and type to the vehicle's stan-
dard tyres. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

Tyre chains
Since the sidewalls of radial tyres are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tyres is rec-
ommended instead of snow chains. Do
not mount tyre chains on vehicles
equipped with aluminum wheels; snow
chains may cause damage to the wheels.
If snow chains must be used, use wire-
type chains with a thickness of less than
12 mm (0.47 in). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
Install tyre chains only on the front tyres.Chain installation
When installing chains, follow the manu-
facturer's instructions and mount them as
tightly as you can. Drive slowly with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until it stops. Remove the
chains as soon as you begin driving on
cleared roads.
CAUTION
Make sure the snow chains are
the correct size and type for your
tyres. Incorrect snow chains cancause damage to the vehicle bodyand suspension and may not be covered by your vehicle manufac-
turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehicle
components causing the snow chains to come loose from thetyre. Make sure the snow chainsare SAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.5 to 1 km (0.3 to0.6 miles) to ensure safe mount-ing. Retighten or remount the
chains if they are loose.
WARNING
- Mounting chains
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place
a triangular emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.1JBA4068

Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorised HYUNDAI
dealer or a service station. Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tyre chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
Do not take this vehicle through anautomatic car wash whilst the com- pact spare tyre is installed.
Do not use tyre chains on the com- pact spare tyre. Because of the
smaller size, a tyre chain will not fit
properly. This could damage the
vehicle and result in loss of thechain.
The compact spare tyre should not be installed on the front axle if the
vehicle must be driven in snow or
on ice.
Do not use the compact spare tyre on any other vehicle because thistyre has been designed especially
for your vehicle.
The compact spare tyre’s tread life is shorter than a regular tyre.
Inspect your compact spare tyre
regularly and replace worn com-
pact spare tyres with the same sizeand design, mounted on the samewheel. The compact spare tyre should not
be used on any other wheels, nor
should standard tyres, snow tyres,
wheel covers or trim rings be used
with the compact spare wheel. Ifsuch use is attempted, damage tothese items or other car compo-
nents may occur.
Do not use more than one tempo- rary spare tyre at a time.
Do not tow a trailer whilst the tem- porary spare tyre is installed.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tyre pres-sures at the proper levels. If a tyre frequently needs refilling,have it checked by an autho-rised HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe centre of the tyre tread,and a greater possibility ofdamage from road hazards.
TYRES AND WHEELS
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 inflation 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 than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tyre
wear.
For recommended inflation pressure,
refer to “Tyre and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tyre underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother 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
Disc brake pads should be inspectedfor wear whenever tyres are rotated.
✽✽ NOTICE
Rotate radial tyres that have an
asymmetric tread pattern only from
front to rear and not from right to
left.
Wheel alignment and tyre balance
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 needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.

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.
CAUTION
Improper wheel weights can
damage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.
