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.

Air conditioning system operation tips
If the vehicle has been parked in directsunlight 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 win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating 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, even if only for a few minutes,
to ensure maximum system perform-
ance.
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 does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box, filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized Hyundai deal-
er.

Driving your vehicle
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 cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in Section 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 puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in Section
7. The level of charge in your battery can
be checked by an authorized Hyundai
dealer or a service station.
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See Section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized Hyundai dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
Section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
To keep locks from freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorized Hyundai
dealer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.

Driving your vehicle
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.
