Air conditioning system operation
tips
If the vehicle has been parked indirect 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 recir-
culated 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 condition-
ing system with the windows and
sunroof closed.
Use the air conditioning system every month only for a few minutes to
ensure maximum system perform-
ance.
If you operate air conditioner exces- sively, the difference between the
temperature 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 control to the lower speed.
System Maintenance
Climate control air filter
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 air con-
ditioner filter inspections and
changes are required. If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

Because the refriger-

pressure, the air con-

should only be serv-

technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.
WARNING

Driving your vehicle

- When using tire chains:
Wrong size chains or improperlyinstalled 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 glycolcoolant
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 ifnecessary
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.
Check spark plugs and ignitionsystem
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
