that can't be seen through the
camera.
• Always keep the camera lens
clean. If the lens is covered with
foreign matter, the camera may
not operate normally.

Driving your vehicle
Before entering vehicle
• Be sure that all windows, outside mir-
ror(s), and outside lights are clean.
• Check the condition of the tires.
• Check under the vehicle for any sign of
leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in sec-
tion 7, “Maintenance”.
Before starting
• Close and lock all doors.
• Position the seat so that all controls are
easily reached.
• Adjust the inside and outside rearview
mirrors.
• Be sure that all lights work.
• Check all gauges.
• Check the operation of warning lights
when the engine start/stop button is

iar with your vehicle and its equipment.
BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
vehicle into D (Drive) or R
(Reverse).
WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
Driving while distracted can result in
a loss of vehicle control, that may
lead to an accident, severe personal
injury, and death. The driver’s primary
responsibility is in the safe and legal
operation of a vehicle, and use of any
handheld devices, other equipment,
or vehicle systems which take the
driver’s eyes, attention and focus
away from the safe operation of a
vehicle or which are not permissible
by law should never be used during
operation of the vehicle.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
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.
BRAKE SYSTEM
(Continued)
• When descending a long or steep
hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
• Wet brakes may impair the vehi-
cle’s ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
• Always, confirm the position of
the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
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.
WARNING- Brakes
• Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.

Driving your vehicle
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.
