Information
The ESC system must be turned OFF
before rocking the vehicle.
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, pos-
sible damage to the transmission,
and tire damage. See "Towing" in
chapter 6.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:
Slow down and keep more dis- tance between you and other vehi-
cles, as it may be more difficult tosee at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the glare from other driver's head-
lamps.
Keep your headlamps clean and properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head- lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.

Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
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.

If your engine coolant 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. Turn ON the hazard warning flash-er, pull off the road and stop as
soon as it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake.
3. Make sure that there is no hotsteam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pumpconnector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air flow to the maximum, and turn ON
the air conditioner. 5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hotsteams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.

What to do in an emergency
7. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Your vehicle is equipped with a pres-
surized coolant
reserve tank. NEVER
remove the coolant
reserve tank cap or the radiatordrain plug while 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 remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while thepressure is released.
When you are sure all the pres-
sure has been released, contin-ue turning the cap counter-
clockwise to remove it.
WARNING

What to do in an emergency
Do not use the Tire Mobility Kit if atire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 minutes at a
time or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -30°C (-22°F).

What to do in an emergency
The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only. This instruction shows
you step by step how to temporarily
seal the puncture simply and reliably.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of theTire Mobility Kit
Park your car at the side of the road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas locatedwithin the tread region of the tirecan be sealed using the tire mobil-ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 0.24 in (6 mm).
If the tire cannot be made roadwor-
thy with the Tire Mobility Kit, we
recommend that you contact an
authorized HYUNDAI dealer. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -22°F (-30°C).
In case of skin contact with the sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
In case of eye contact with the sealant, flush your eyes for at least
15 minutes. If the irritation persists,seek medical attention.

Do not use the TMK if a tire is
severely damaged by driving runflat or with insufficient air pres-
sure.
Only punctured areas located within the tread region of the tire
can be sealed using the TMK.
