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

To keep locks from freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.
✽✽NOTICE
The operating temperature range for an
immobiliser key is between -40°C to
80°C. If you heat an immobiliser key
above 80°C to open a frozen lock, you
may damage the transponder located in
the head of the key.
E120700AFD-EA
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorised HYUNDAI
dealer and most auto parts outlets. Donot use engine coolant or other types of
anti-freeze as these may damage thepaint finish.
E120800AUN-EA
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily while you put the gear selector lever in
P (automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the car cannot
roll. Then release the parking brake. E120900AUN
Don't let ice and snow accumu- late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
E121000AUN-EA
Carry emergency equipment
Depending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tyre chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,etc.

If you are considering towing with your
car, you should first check with your
country's Department of Motor Vehicles
to determine their legal requirements.
Since laws vary the requirements for tow-
ing trailers, cars, or other types of vehi-
cles or apparatus may differ. Ask an
authorised HYUNDAI dealer for further
details before towing.
Your vehicle can tow a trailer. To identify
what the vehicle trailering capacity is for
your vehicle, you should read the infor-
mation in “Weight of the trailer” thatappears later in this section.
Remember that trailering is different than
just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful,
safe trailering requires correct equip-
ment, and it has to be used properly.This section contains many time-tested,
important trailering tips and safety rules.
Many of these are important for your
safety and that of your passengers.
Please read this section carefully before
you pull a trailer. Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tyres are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat.
The trailer also adds considerably to
wind resistance, increasing the pulling
requirements.
TRAILER TOWING
CAUTION
Pulling a trailer improperly can
damage your vehicle and result in costly repairs not covered by yourwarranty. To pull a trailer correctly,
follow the advice in this section.
WARNING - Towing a trail-
er
If you don't use the correct equip-
ment and drive improperly, you can
lose control when you pull a trailer.
For example, if the trailer is too
heavy, the brakes may not work
well - or even at all. You and your
passengers could be seriously or
fatally injured. Pull a trailer only if
you have followed all the steps inthis section.
WARNING - Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, grossaxle weight and trailer tongue loadare all within the limits.

Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.E140407AUN-EA
Parking on hills
Generally, you should not park your vehi-
cle, with a trailer attached, on a hill.
People can be seriously injured or cause
fatality, and both your vehicle and the
trailer can be damaged if they begin a
downhill trajectory.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Apply your brakes, but don’t shift into
gear.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brakes until the chocks absorb the load.
4. Reapply the brakes. Apply your park- ing brake, and then shift to R
(Reverse) for a manual transaxle or P
(Park) for an automatic transaxle.
5. Release the brakes.
CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge to
ensure the engine does not over- heat.
If the needle of the coolant tem-perature gauge moves across thedial towards “H” (HOT), pull over
and stop as soon as it is safe to do so, and allow the engine to idleuntil it cools down. You may pro-
ceed once the engine has cooledsufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-
bility of engine and transaxle overheating.
WARNING - Parking on a
hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break lose.

When you are ready to leave after park- ing on a hill
1. With the manual transaxle in Neutral
or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks. E140500AUN-EA
Maintenance when trailer towing
Your vehicle will need service more often
when you regularly towing a trailer.
Important items to pay particular atten-tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to check frequently. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re towing, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and towbar. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all towbar nutsand bolts should be tight.
WARNING
- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others can be seriously injured
or cause fatality.CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicates
over-heating, switch off the A/C and stop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan to improve engine performance
when towing a trailer.

If you do decide to pull a trailer
Here are some important points if you
decide to pull a trailer:
Consider using a sway control. You canask a towbar dealer about sway con- trol.
Do not do any towing with your car dur- ing its first 2,000 km (1,200 miles) in
order to allow the engine to properly
break in. Failure to heed this caution
may result in serious engine or
transaxle damage.
When towing a trailer, be sure to con- sult an authorised HYUNDAI dealer for
further information on additional
requirements such as a towing kit, etc.
Always drive your vehicle at a moder- ate speed (less than 100 km/h (60mph)).
On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.
