placing the ignition
switch to the ON posi-
tion (do not start the

tion.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.If the Parking Brake Warning Light
remains on after the parking brake is
released whilst the engine is run-
ning, there may be a malfunction in
the brake system. Immediate atten-
tion is necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution whilst
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.CAUTION

Driving your vehicle
✽NOTICE
When you jump start your vehicle
because of a drained battery, the
ABS warning light ( ) may turn
on at the same time. This happens
because of the low battery voltage. It
does not mean your ABS is malfunc-
tioning. Have the battery recharged
before driving the vehicle.
Electronic Stability Control
(ESC) (if equipped)
The Electronic Stability Control
(ESC) system helps to stabilise the
vehicle during cornering manoeu-
vres.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle’s brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres, and hydroplaning
on wet surfaces can result in
severe accidents.

ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
If this light stays on, your vehicle may
have a malfunction with the ESC
system. We recommend that the
vehicle be checked by an authorised
HYUNDAI dealer as soon as possi-
ble.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
• When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
• When the ESC activates, the
engine may not respond to the
accelerator as it does under rou-
tine conditions.
• If the Cruise Control was in use
when the ESC activates, the cruise
control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow. See “Cruise Control System”
later in this chapter.• When moving out of the mud or
driving on a slippery road, the
engine rpm (revolutions per
minute) may not increase even if
you press the accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem.
