humidity to increase inside the
vehicle which may fog the glass
and obscure visibility.
Do not sleep in a vehicle with the
air conditioning or heating system
on. It may cause serious harm or
death due to a drop in the oxygen
level and/or body temperature.
Continued use of the climate con-
trol system operation in the recir-
culated air position can cause
drowsiness or sleepiness, and loss
of vehicle control. Set the air intake
control to the outside (fresh) air
position as much as possible while

Features of your vehicle
Climate control air filter
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 vehicle 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 negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽ ✽
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor and
abnormal system operation may occur. OMG075033

WINDSHIELD DEFROSTING AND DEFOGGING
. For maximum defrosting, set the temper-
ature control to the extreme right/hot
position and the fan speed control to the
highest 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, outside rear
view mirrors, and all side windows.
Clear all snow and ice from the hood and
air inlet in the cowl grill to improve heater

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 knob
or button to the position and
fan speed control knob or button to

Disc brakes wear indicator
Your vehicle has disc brakes.
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 when-
ever you depress the brake pedal.
Please remember that some driving condi-
tions 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.
Parking brake
Applying the parking brake
To engage the parking brake, first apply the
service brake and then depress the parking
brake pedal down as far as possible.
Releasing the parking brake
To release the parking brake, depress
the parking brake pedal a second time
while applying the service brake. The
pedal will automatically extend to the fully
released position.
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 worn
brake pads.
Always replace the front or rear
brake pads as pairs.
OYF059023OYF059025
CAUTION
Driving with the parking brake
applied will cause excessive
brake pad and brake rotor wear.
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
applying the brake.
