Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden braking or steering. If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tire chains, or
other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
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 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle.
Do not race the engine, and spin the
wheels as little as possible. If you are still
stuck after a few tries, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating and possible dam-
age to the transaxle.
SPECIAL DRIVING CONDITIONS
1JBB3302
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
CAUTION
Prolonged rocking may cause
engine over-heating, transaxle dam-
age or failure, and tire damage.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.

WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi-
cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
car. For further information and
tread limits, refer to “Tires and
wheels” in section 7.
OMG015008
CAUTION
A loose or damaged drive belt may
result in overheating of the engine.
Inspect your drive belt for proper
tension, or have your Hyundai deal-
er inspect this at the normal service
intervals listed in section 7.

What to do in an emergency
Jump starting procedure
1. Make sure the booster battery is 12-
volt and that its negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical
loads.
4. Connect the jumper cables in the exact
sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2). Proceed to
connect one end of the other jumper
cable to the negative terminal of the
booster battery (3), then the other end
to a solid, stationary, metallic point (for
example, the engine lifting bracket)
away from the battery (4). Do not con-
nect it to or near any part that moves
when the engine is cranked.Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
5. Start the engine of the vehicle with the
booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, you should have your vehi-
cle checked by an authorized HYUNDAI
dealer.
Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section for
jump-starting.
CAUTION- Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-
minal of the discharged battery.
This can cause the discharged bat-
tery to overheat and crack, releas-
ing battery acid.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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 (automatic
transaxle) or neutral (manual transaxle)
and set the parking brake. If the air con-
ditioning is on, turn it off.
3. If engine coolant is running out under
the car or steam is coming out from
the hood, stop the engine. Do not open
the hood 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.4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized
HYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This may
result in coolant being blown out of
the opening and cause serious
burns.

What to do in an emergency
Notes on the safe use of the Tire
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. Place your warning triangle
in a prominent place to make pass-
ing vehicles aware of your location.
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. Do not use on motorcycles,
bicycles or any other type of tires.
Do not remove any foreign objects
such as nails or screws that have
penetrated the tire.
Before using the Tire Mobility Kit,
read the precautionary advice
printed on the sealant bottle! 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).
Do not use the sealing compound
after its expiration date which can
be found on the label of the bottle.
Keep away from children.
WARNING
Have your tire repaired as soon
as possible. The tire may loose
air pressure at any time after
inflating with the TMK.
CAUTION
The Tire Mobility Kit is a tempo-
rary fix to the tire and the tire
should be inspected by an
authorized HYUNDAI dealer as
soon as possible.
CAUTION
When using Tire Mobility Kit, the
tire sealant can damage the tire
pressure sensor. After using the
Tire Mobility Kit, have the tire
pressure sensor checked by an
authorized HYUNDAI dealer.
