ODN8069001
Whenever the front door is opened, the
Engine Start/Stop button will illuminate
and will go off 30 seconds after the door is closed.
WARNING
To reduce risk of serious injury or death,
NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the Engine Start/Stop button or
related parts. Unexpected and sudden
vehicle movement can occur.
WARNING
To turn the engine off in an emergency:
Press and hold the Engine Start/Stop
button for more than two seconds OR
rapidly press and release the Engine
Start/Stop button three times (within
three seconds).
If the vehicle is still moving, you can
restart the engine without depressing
the brake pedal by pressing the Engine
Start/Stop button with the shift button
in the N (Neutral) position.
WARNING
• NEVER press the Engine Start/Stop
button while the vehicle is in motion
except in an emergency. This will
result in the engine turning off and
loss of power assist for the steering
and brake systems.
This may lead to loss of directional
control and braking function, which
could cause an accident.
• Before leaving the driver's seat,
always make sure the shift button
is in the P (Park) position, set the
parking brake, press the Engine
Start/Stop button to the OFF
position, and take the Smart Key with
you. Unexpected vehicle movement
may occur if these precautions are
not followed.

wheel for the Engine Start/Stop
button or any other control while the
vehicle is in motion. The presence
of your hand or arm in this area
may cause a loss of vehicle control
resulting in an accident.

and goes off in approximately 3 seconds
if the system is operating normally.
If the EPB malfunction indicator
remains on, comes on while driving, or
does not come on when the ignition
switch is changed to the ON position,
this indicates that the EPB may have malfunctioned.
If this occurs, have the system checked
by an authorized HYUNDAI dealer.
The EPB malfunction indicator may
illuminate when the ESC indicator comes
on to indicate that the ESC is not working
properly, but it does not indicate a
malfunction of the EPB.
NOTICE

WARNING
If ESC indicator light (
) or EPS
warning light () stays on or blinks,
your vehicle may have a malfunction
with the VSM system. When the
warning light illuminates, have your
vehicle checked by an authorized
HYUNDAI dealer as soon as possible.
Driving with wheels and tires with
different sizes may cause the ESC system
to malfunction. Before replacing tires,
make sure all four tires and wheels are
the same size. Never drive the vehicle
with different sized tires and wheels
installed.
Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle from
a stop on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off on
a incline. The HAC activates only for
approximately 2 seconds.
NOTICE
• The HAC does not operate when
the shift button is in P (Park) or N
(Neutral)
• The HAC activates even though the
ESC (Electronic Stability Control) is
off but does not activate when the ESC has malfunctioned.
Good Braking Practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift button into P
(Park) position, then apply the parking
brake, and place the ignition switch in
the LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the vehicle
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorized HYUNDAI dealer for
assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.
