NOTICE• While using the air conditioning sys-
tem, monitor the engine temperature
gauge closely while driving up hills or
in heavy traffic when outside temper-
atures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the engine temperature
gauge indicates engine overheating.
• Opening the windows in humid weather while air conditioning oper-
ates may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to electri-
cal equipment, air conditioning
should only be used with the windows
closed.
Air conditioning system operation tips
• If the vehicle has been parked in direct
sunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
• To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
• Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
• When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. • Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, continual
operation in this mode may cause the
air inside the vehicle to become stale.
• During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and humid air
intake. This is a normal system opera-
tion characteristic.
• If you operate air conditioner exces- sively, the difference between the tem-
perature of the outside air and that of
the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility. In this case,
set the mode selection knob or button
to the position and fan speed con-
trol to the lower speed.

Driving your vehicle30
5• Don't "ride" the brake pedal. Resting
your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
• If a tire goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
• If your vehicle is equipped with an automatic transaxle, don't let your vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped. • Use caution when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.
• Under some conditions your parking brake can freeze in the engaged posi-
tion. 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. If there is a risk that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake. • Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.

Driving your vehicle
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 in 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 causeengine over-heating, transaxle dam-age or failure, and tire damage.

5Highway drivingTiresAdjust 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.✽
NOTICENever exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oilHigh speed travel consumes more fuel
than urban motoring. Do not forget to
check both engine coolant and engine
oil.Drive beltA loose or damaged drive belt may result
in overheating of the engine.
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.

What to do in an emergency6
6IF THE ENGINE OVERHEATSIf 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 systemand this should be checked as soonas possible by an authorizedHYUNDAI 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.
