The more severe weather conditions of
winter result in greater wear and other
problems. To minimise the problems of
winter driving, you should follow thesesuggestions:
E120100AUN-EA
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 states.
Check state laws before fitting tyrechains.
E120101AUN-EA
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 aluminium 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
15 mm (0.59 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 yourtyres. Incorrect snow chains cancause damage to the vehicle body
and suspension and may not becovered by your vehicle manufac- turer warranty. Also, the snowchain connecting hooks may be
damaged from contacting vehiclecomponents causing the snowchains to come loose from the tyre. Make sure the snow chains
are SAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.5 to 1 km (0.3 to
0.6 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
park (P), 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. E120300AFD-EA
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. E120400AFD-EA
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 9
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
E120500AUN
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.
CAUTION
Chains that are the wrong size or
improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
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.

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. G200200AFD-EA 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 section9. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tyre underin-
flation
Severe underinflation (70 kPa (10 psi) or more) 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.

Tyre rotation
To equalize tread wear, it is recom- mended that the tyres be rotated
every 12,000 km (7,500 miles) 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 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 thefront and rear tyre pressures to spec-
ification and check wheel nut tight-
ness.
Refer to “Tyre and wheels” in section 9.Disc brake pads should be inspected
for wear whenever tyres are rotated.
✽✽ NOTICE
Rotate radial tyres that have an
asymmetric tread pattern only from
front to rear and not from right toleft.

G200500AUN-EA 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.G200600BFD-EA
Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This showsthere is less than 1.6 mm (1/16 inch)
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.
CAUTION
Improper wheel weights can
damage your vehicle's alumini- um wheels. Use only approvedwheel weights.

Tread wear indicatorWARNING - 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 andtype 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.

G200700BUN-EA 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 widthand offset. G200800AUN-EA
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.
G200900AUN-EA
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 thewheel 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 removedfrom the wheel.(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 tyre can
seriously affect your vehicle’shandling.
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
ESP (Electronic Stability
Program) (if equipped) to
work irregularly.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tyre clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.
