Operation Tips
To keep dust or unpleasant fumes from
entering the car through the ventilation
system, temporarily set the air intake
control to the recirculated air position.
Be sure to return the control to the
fresh air position when the irritation
has passed to keep fresh air in the
vehicle. This will help keep the driver
alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just ahead
of the windshield. Care should be
taken that these are not blocked by
leaves, snow, ice or other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to the
fresh air position and fan speed to the
desired position, turn on the air condi-
tioning system, and adjust temperature
control to desired temperature.
Air conditioning (if equipped)
All Hyundai Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which is not damag-
ing to the ozone layer.
1. Start the engine. Push the air condi- tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and tem- perature control to maintain maximum
comfort.
When maximum cooling is desired, set the temperature control to the extreme
left position, set the mode control to
the MAX A/C position, then set the fan
speed control to the highest speed.✽ ✽ NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures 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 temperature gauge indi-
cates engine overheating.
• When opening the windows in humid weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.

Cigarette lighter
For the cigarette lighter to work, the igni-
tion switch, must be in the ACC position
or the ON position.
To use the cigarette lighter, push it all the
way into its socket. When the element
has heated, the lighter will pop out to the
"ready" position.
Do not hold the cigarette lighter pressed
in. This can damage the heating element
and create a fire hazard.
If it is necessary to replace the cigarette
lighter, use only a genuine Hyundai
replacement or its approved equivalent.
Ashtray
The front ashtray may be opened by
pulling the ashtray lid. To clean the ash-
tray, the plastic receptacle should be
removed by lifting the plastic ash recep-
tacle upward and pulling it out.

Driving your vehicle
Don't "ride" the brake pedal. Restingyour 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 car is equipped with an auto- matic transaxle, don't let your car
creep forward. To avoid creeping for-
ward, keep your foot firmly on the
brake pedal when the car is stopped.
Use caution when parking on a hill. Firmly engage the parking brake and
place the gear selector lever in "P"
(automatic transaxle) or in first or
reverse gear (manual transaxle). If
your car is facing downhill, turn the
front wheels into the curb to help keep
the car from rolling. If your car is facing
uphill, turn the front wheels away from
the curb to help keep the car from
rolling. If there is no curb or if it is
required by other conditions to keep
the car 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 car 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.

Higher speed motoring
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.
Drive belt:
A 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 the tires for proper
inflation before driving. For prop-
er tire pressures, refer to section
8, “Tires and wheels”.
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 section 7,
“Tires and wheels”.

Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 20 mph (30
km/h) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transaxle.
Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the curb (right if headed down hill,
left if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge toensure the engine does not over- heat. If the needle of the coolanttemperature gauge moves acrossthe dial towards “H” (HOT), pullover and stop as soon as it is safeto do so, and allow the engine toidle until it cools down. You mayproceed once the engine hascooled sufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxleoverheating.
WARNING- Parking on a hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break lose.

5. Start the vehicle, hold the brakes, shiftto neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes, reapply the park- ing brake and shift the vehicle to R
(Reverse) for manual transaxle or P
(Park) for automatic transaxle.
7. Shut off the vehicle and release the vehicle brakes but leave the parking
brake set.
When you are ready to leave after park-
ing on a hill
1. With the manual transaxle in Neutral or automatic transaxle in P (Park),
apply your brakes and hold the brake
pedal down while 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 trailer towing
Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip.
Don’t forget to also maintain your trailer
and hitch. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and bolts should be tight.
WARNING- Parking brake
It can be dangerous to get out of
your vehicle if the parking brake is
not firmly set.
If you have left the engine running,
the vehicle can move suddenly. You
or others could be seriously or
fatally injured.
CAUTION
Due to higher load during trailer usage, overheating might occurin hot days or during uphill driv- ing. If the coolant gauge indicatesover-heating, switch off the A/Cand stop the vehicle in a safe area to cool down the engine.
When towing check transaxle fluid more frequently.
If your vehicle is not equipped with the air conditioner, youshould install a condenser fan toimprove engine performancewhen towing a trailer.

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.
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.
