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
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.
Electric parking brake (EPB)
Applying the parking brake
To engage the parking brake, first apply
the brake pedal and then pull the EPB
switch. Make sure that the brake warning
light comes on.
Releasing the parking brake
The parking brake will be released auto-
matically when you shift the shift lever
from P (Park) to R (Reverse), N (Neutral)
or D (Drive) while depressing the brake
pedal.
To release the parking brake manually
with the engine start/stop button in the
ON position, press the EPB switch while
depressing the brake pedal. Make sure
that the brake warning light goes off.
If the parking brake does not release,
have the system checked by an author-
ized HYUNDAI dealer.
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 brake pads as
complete front or rear axle sets.
CAUTION
Do not operate the parking brake
while the vehicle is moving except
in an emergency situation. It could
damage the vehicle system and
make endanger driving safety.

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.
W-75OVI059011
CAUTION
• A click sound may be heard while
operating or releasing the EPB.
These conditions are normal and
indicate that the EPB is function-
ing properly.
• When leaving your keys with a
parking lot attendant or valet,
make sure to inform him/her how
to operate 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.

HYUNDAI dealer and have the system
checked.The ECS 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 malfunc-
tion of the ECS.
✽NOTICE
If the battery is discharged or if you
push the SPORT button or the vehicle
height control button repeatedly in
short time, the ECS malfunction indica-
tor may illuminate to protect the system.
CAUTION
If the ECS malfunction indicator
illuminates when there is no air in
the suspension, the vehicle height
will be very lower, so do not drive to
protect the vehicle from the projec-
tions on the surface of the ground.
Take your vehicle to an authorized
HYUNDAI dealer by towing the vehi-
cle and have the system checked.
You should tow the vehicle as the
