WARNING
The continuous use of recirculat-ed air in the climate control sys-
tem may increase humidity inside
the vehicle, causing the glass to
fog and obscuring visibility.
Do not sleep in a vehicle with the air conditioning or heating sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
The continuous use of recirculat- ed air in the climate control sys-
tem can produce drowsiness or
sleepiness, which may result in a
loss of vehicle control. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.

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.
Use air conditioning to reduce humidi- ty and moisture inside the vehicle on
rainy or humid days.
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.
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
dealer.

✽
✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽ ✽ NOTICE
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system operation
may occur.
WARNING
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.

For maximum defrosting, set the tem-perature control to the hottest position
and the fan speed control to the high-
est speed.
If warm air to the floor is desired while defrosting or defogging, set the mode
to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood and air inlet in the cowl grill to improve
heater and defroster efficiency and to
reduce the probability of fogging up the
inside of the windshield.
Manual climate control system
To defog inside windshield
1. Set the fan speed to the desired posi- tion.
2. Select desired temperature.
3. Select the position.
4. The outside (fresh) air will be selected automatically. If the position is
selected, air conditioning (if equipped)
will also be selected automatically.
If the air conditioning and/or outside
(fresh) air position are not selected auto-
matically, press the corresponding button
manually.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING- Windshield heating
Do not use the position during
cooling operation in extremely
humid weather. The difference
between the temperature of the out-
side air and the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection to the position
and fan speed control to the lower
speed.

Features of your vehicle
Auto defogging system (Only for automatic climate controlsystem, if equipped)
Auto defogging reduces the possibility of
fogging up the inside of the windshield by
automatically sensing the moisture of
inside the windshield.
The auto defogging system operates
when the AUTO mode is on. This indicator illuminates
when the auto defogging
system senses the moisture
of inside the windshield and
operates.
If more moisture is in the vehicle, higher
steps operate as follow.
Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 : Blowing air flow toward the wind- shield
Step 4 : Increasing air flow toward the windshield
If your vehicle is equipped with the auto
defogging system, it is automatically acti-
vated when the conditions are met.
However, if you would like to cancel the
auto defogging system, press the front
defroster button 4 times within 2 seconds
while pressing the AUTO button. The
indicator will blink 3 times to notify you
that the system is cancelled. To use the
auto defogging system again, follow the
procedures mentioned above.
If the battery has been disconnected or
discharged, it resets to the auto defog-
ging status.
✽ ✽ NOTICE
If the A/C off is manually selected while
the auto defogging system is on, the auto
defogging indicator will blink 3 times to
give notice that the A/C off can not be
selected.

In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
Disc brakes wear indicator
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to a
serious accident.
CAUTION
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
Always replace the front or rear brake pads as pairs.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
