Driving your vehicle
Hazardous driving conditions
When hazardous driving elements are
encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in snow,
mud, or sand, use the second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tyre chains or
other non-slip materials under the
wheels to provide additional traction
whilst the vehicle becomes stuck in
ice, snow, or mud.
WARNING
Downshifting with an Automatic
transmission, whilst driving on slippery
surfaces can cause an accident. The
sudden change in tyre speed could
cause the tyres to skid. Be careful when
downshifting on slippery surfaces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left to
clear the area around your front wheels.
Then, shift back and forth between the
1st gear and R (Reverse, for manual
transmission vehicle) or R (Reverse)
and a forward gear (for Automatic
transmission vehicle/Dual clutch
transmission vehicle).
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
whilst shifting, and press lightly on the
accelerator pedal whilst the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tyres can increase very quickly.
If the tyres become damaged, a tyre
blow out or tyre explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damages. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tyres
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).

NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tyre damage.
See “Towing” in chapter 8.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:

could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

Driving your vehicle
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as
the depth of tyre tread decreases, refer
to “Tyre replacement” in chapter 9.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them several
times whilst the vehicle is moving
slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or damage
the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or fail
the braking operation.

Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine
coolant level and the engine oil before
driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

The severe weather conditions of winter
quickly wear out tyres and cause other
problems. To minimise winter driving
problems, you should take the following
suggestions:
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. 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 applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tyres or
to install tyre chains on your tyres.
Always carry emergency equipment.
Some of the items you may want to
carry include tyre chains, tow straps or
chains, a flashlight, emergency flares,
sand, a shovel, jumper cables, a window
scraper, gloves, ground cloth, coveralls,
a blanket, etc.
Snow tyres
WARNING
Snow tyres should be equivalent
in size and type to the vehicle’s
standard tyres. Otherwise, the safety
and handling of your vehicle may be
adversely affected.
If you mount snow tyres on your vehicle,
make sure to use 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 handling in
all weather conditions. The traction
provided by snow tyres on dry roads
may not be as high as your vehicle’s
original equipment tyres. Check with
the tyre dealer for maximum speed
recommendations.

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.
