WARNING - ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia- tion.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshie ld are
kept clear of snow, ice, leaves or other obstructions.

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.Electronic parking brake (EPB)

Driving your vehicle
Check the brake warning light by turning
the engine start/stop button ON (do not
start the engine). This light will be illumi-
nated when the parking brake is applied
with the engine start/stop button in the
START or ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released while
the engine is running, there may be a
malfunction in the brake system.
Immediate attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-tion.EPB malfunction indicator
This warning light illuminates if the
engine start/stop button is turned to the
ON position and goes off in approximate-
ly 3 seconds if the system is operation
normally. If the EPB malfunction indicator remains
on, comes on while driving, or does not
come on when the engine start/stop but-
ton is turned to the ON position, this indi-
cates that the EPB may have malfunc-tioned.
If this occurs, have your vehicle checked
by an authorized HYUNDAI dealer as
soon as possible.The EPB malfunction indicator may illu-minate when the ESP indicator comes on
to indicate that the ESP is not working
properly, but it does not indicate a mal-
function of the EPB.

Driving your vehicle
Electronic stability program (ESP)
The Electronic Stability Program (ESP)
system is designed to stabilize the vehicle
during cornering maneuvers. ESP checks
where you are steering and where the
vehicle is actually going. ESP applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.The Electronic Stability Program (ESP)system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
program (ESP) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESP installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.
