When installing tyre chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) 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 the noise stops. Remove
the tyre chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park
the vehicle on level ground away from
traffic. Turn on the vehicle Hazard
Warning Flasher and place a triangular
emergency warning device behind the
vehicle (if available). Always place the
vehicle in P (Park), apply the parking
brake and turn off the engine before
installing snow chains.
NOTICE
When using tyre chains:

[Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.

[Use SAE “S” class or wire chains.

[If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.

[To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).

[Do not use tyre chains on vehicles
equipped with aluminium wheels. If
unavoidable, use a wire type chain.

[Use wire chains less than 0.47 in (12
mm) wide to prevent damage to the
chain’s connection.
Winter Precautions
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, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule. Before
winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in the chapter
9. The battery charging level can be
checked by a HYUNDAI authorised
repairer or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. For
further information, refer to the chapter
2. When you are not sure about a type
of winter weight oil, consult a HYUNDAI
authorised repairer.

6-64
Driving your vehicle
Check spark plugs and ignition system
Inspect the spark plugs, as specified
in the chapter 9. If necessary, replace
them. Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from a HYUNDAI authorised
repairer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution to
prevent any damage to the vehicle paint.
Do not 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. When there is the
risk that your parking brake may freeze,
temporarily apply it with the shift lever
in N (for Automatic Transmission/Dual
clutch transmission) or in the 1st gear or
reverse gear (for Manual transmission).
Also, block the rear wheels in advance,
so the vehicle may not roll. Then, release
the parking brake.Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, whilst driving. Some of the
items you may want to carry include tyre
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
engine compartment
Putting objects or materials in the
engine compartment may cause an
engine failure or combustion, because
they may block the engine cooling.
Such damage will not be covered by the
manufacturer’s warranty.

6-72
Driving your vehicle
Ready to leave after parking on a
hill
1. With the shift lever to P (Park, for
Automatic transmission/Dual clutch
transmission vehicle) or neutral (for
Manual transmission vehicle), apply
your brakes and hold the brake pedal
down whilst you:

V Start your engine;

V Shift into gear; and

V Release the parking brake.
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.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
automatic transmission/dual clutch
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items 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, conduct the
check at the start of each day’s driving.
Most importantly, all towbar nuts and
bolts should be tight.
NOTICE
To prevent vehicle damage:

V Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving. If
the coolant gauge indicates over-
heating, switch off the air conditioner
and stop the vehicle in a safe area to
cool down the engine.

V When towing check Automatic
transmission/Dual clutch
transmission fluid more frequently.

V If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle or steam is coming out
from the bonnet, stop the engine. Do
not open the bonnet until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
Whilst the engine is
running, keep hands,
clothing and tools away
from the moving parts such
as the cooling fan and drive
belt to prevent serious
injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we
recommend that you call a HYUNDAI
authorised repairer for assistance.
WARNING
NEVER remove the radiator
cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back whilst the pressure
is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove it.
