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.

Driving your vehicle
Use wire chains less than 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. 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 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.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 chapter
8. When you are not sure about a
type of winter weight oil, consult an
authorised HYUNDAI dealer.
Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in chapter 7.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.

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.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
dual clutch transmission P (Park)
function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal). Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm, whilst running the
diesel engine. The high currents
of the electronic engine control
system produce a considerable
amount of magnetic fields.
