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 increas-
es as the depth of tyre tread
decreases, refer to "Tyre Tread" in
chapter 7.
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 sev-
eral times whilst the vehicle is mov-
ing 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
adversely affect vehicle handling and
braking.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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:
Information
Summer tyres are equipped to provide
the best driving performance on dry
roads, varying according to specifica-
tion. Since vehicles equipped with
summer tires significantly reduce sur-
face forces when driving on snow or
ice roads, it is recommended to use
snow tyres of the same size as the stan-
dard tyres of the vehicle or the replace
them with all seasons tires or to use
chains.
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 skids to occur.
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
We recommend you use snow tyres
when road temperature is below 7°C
(45°F).
If you mount snow tyres on your vehi-
cle, 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 vehi-
cle’s handling in all weather condi-
tions. The traction provided by snow
tyres on dry roads may not be as
high as your vehicle's original equip-
ment tyres. Check with the tyre deal-
er for maximum speed recommenda-
tions.

Snow tyres should be equivalent
in size and type to the vehicle's
standard tyres. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.
WARNING
Using summer tyres at very
cold temperature could cause
cracks on them to be formed
and damage them permanently.

Information
• Install tyre chains on both left and
right front tyres. It should be noted
that installing tyre chains on the
tyres will provide a greater driving
force, but will not prevent side
skids.
• Do not install studded tyres without
first checking local and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing tyre chains, follow
the manufacturer's instructions and
mount them as tightly as possible.
Drive slowly (less than 30 km/h) with
chains installed. If you hear the
chains contacting the body or chas-
sis, 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.If your vehicle has 225/40R18 or
225/40ZR18 size tyres, do not use
tyre chain; they can damage your
vehicle (wheel, suspension and
body).
If unavoidable use a wire or fabric
type snow chain.
When using tyre chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, 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, retight-
en the chains after driving 0.5~1.0
km.
Do not use tyre chains on vehi-
cles equipped with aluminium
wheels. If unavoidable, use a
wire type chain.

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 spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
HYUNDAI dealer, 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 hap-
pen 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 park-
ing brake may freeze, temporarily
apply it with the shift lever in P
(Park). Also, block the rear wheels in
advance, so the vehicle may not roll.
Then, release the parking brake.Do not let ice and snow accumu-
late underneath
Under some conditions, snow and
ice can build up under the wheel
arches and interfere with the steer-
ing. When driving in such conditions
during a severe winter, you should
check underneath the vehicle on a
regular basis, to ensure that the front
wheels and steering components are
unblocked.
Carry emergency equipment
In accordance with weather condi-
tions, you should carry appropriate
emergency equipment, whilst driv-
ing. Some of the items you may want
to carry include tyre chains, tow
straps or chains, flashlight, emer-
gency flares, sand, shovel, jumper
cables, window scraper, gloves,
ground cloth, coveralls, blanket, etc.

Driving your vehicle
Ready to leave after parking on
a hill
1. With the shift lever in 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:

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.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re towing, it’s
a good idea to review these items
before you start your trip. Don’t forget
to also maintain your trailer and tow-
bar. Follow the maintenance sched-
ule 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 nuts and bolts should be
tight.To prevent vehicle damage:
Due to higher load during trailer
usage, overheating might occur
on hot days or during uphill driv-
ing. If the coolant gauge indi-
cates over-heating, switch off
the air conditioner and stop the
vehicle in a safe area to cool
down the engine.
Do not switch off the engine
whilst the coolant gauge indi-
cates over-heating.
(Keep the engine idle to cool
down the engine)
When towing check automatic
transmission fluid more fre-
quently.
If your vehicle is not equipped
with an air conditioner, you
should install a condenser fan
to improve engine performance
when towing a trailer.

What to do in an emergency
If you have a flat tyre whilst
driving
If a tyre goes flat whilst you are driv-
ing:
Take your foot off the accelerator
pedal and let the vehicle slow
down whilst driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause loss of vehicle
control resulting in an accident.
When the vehicle has slowed to
such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into P (Park,
for automatic transmission/dual
clutch transmission vehicle) or neu-
tral (for manual transmission vehi-
cle), apply the parking brake, and
place the ignition switch in the
LOCK/OFF position.
Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
When changing a flat tyre, follow
the instructions provided later in
this chapter.If the engine doesn't turn over
or turns over slowly
Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transmission/dual clutch
transmission vehicle. The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
Check the battery connections to
be sure they are clean and tight.
Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to start
it. This could cause damage to your
vehicle.See instructions for "Jump
Starting" provided in this chapter.

What to do in an emergency
If the engine turns over nor-
mally but doesn’t start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call an autho-
rised HYUNDAI dealer for assis-
tance.Jump starting can be dangerous if
done incorrectly. Follow the jump
starting procedure in this section to
