If you operate the air conditioner
excessively, the difference
between the temperature of the
outside air and that of the wind-
shield could cause the outer sur-
face of the windshield to fog up,
causing loss of visibility. In this
case, set the mode selection but-
ton to the position and set the
fan speed control knob to the low-
est speed setting.System Maintenance
Climate control air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
This filter is installed behind the
glove box. It filters the dust or other
pollutants that enter the vehicle
through the heating and air condi-
tioning system.Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent climate
control filter inspections and
changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.

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.
After sufficient cooling has been
achieved, switch back from the
recirculated air to the fresh outside
air position.
To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
Use the air conditioning system
every month for a few minutes to
ensure maximum system perform-
ance. If you operate the air conditioner
excessively, the difference
between the temperature of the
outside air and that of the wind-
shield could cause the outer sur-
face of the windshield to fog up,
causing loss of visibility. In this
case, toggle the mode selection
button to the position and set
the fan speed control knob to the
lowest speed setting.

Driving your vehicle
Do not drive in water if the level
is higher than the bottom of the
vehicle.
Check your brake condition
once you are out of mud or
water. Depress the brake pedal
several times as you move slow-
ly until you feel normal braking
return.
Shorten your scheduled mainte-
nance interval if you drive in off-
road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage
Conditions" in chapter 7).
Always wash your vehicle thor-
oughly after off road use, espe-
cially the bottom of the vehicle.
Be sure to equip the vehicle with
four tires of the same size and
type.
Make sure that a full time AWD
vehicle is towed by a flat bed
tow truck.
NOTICEIn the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

Driving your vehicle
- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.59
inch (15 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
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
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.

Driving your vehicle
5. Start the vehicle, apply the brakes,
shift to neutral, release the park-
ing brake and slowly release the
brakes until the trailer chocks
absorb the load.
6. Reapply the brakes and parking
brakes.
7. Move the shift lever to P (Park).
8. Shut off the vehicle and release
the vehicle brakes but leave the
parking brake set.
Driving the vehicle after it has
been parked on a hill
1. With the gear shift lever in P
(Park), apply the brakes and hold
the brake pedal down while per-
forming the following:

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 tow-
ing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transmission fluid, axle lubri-
cant and cooling system fluid. Brake
condition is another important item to
frequently check. If you’re trailering,
it’s a good idea to review these items
before you start your trip. Don't forget
to also maintain your trailer and
hitch. Follow the maintenance sched-
ule that accompanied your trailer and
check it periodically. Preferably,
inspect the vehicle and trailer at the
start of each day's driving. Inspect
the hitch mounting to make sure the
hitch is properly secured to the vehi-
cle. Inspect the trailer electrical
wiring to make sure brake lights, turn
signal lights, running lights, and haz-
ard lights are working properly.
Do not get out of the vehicle
without the parking brake
firmly set. If you have left the
engine running, the vehicle
can move suddenly. You and
others could be seriously or
fatally injured.
Do not apply the accelerator
pedal to hold the vehicle on
an uphill.
