Anti-lock Brake System (ABS)
(if equipped)
ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Press your brake
pedal as hard as possible.
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 ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
• Rough, gravel or snow-cov-
ered roads.
• On roads where the road sur-
face is pitted or has different
surface height.
• Tyre chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.
WARNING
An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
manoeuvres. Even though vehi-
cle control is improved during
emergency braking, always
maintain a safe distance
between you and objects ahead
of you. Vehicle speeds should
always be reduced during
extreme road conditions. The
braking distance for vehicles
equipped with ABS or ESC may
be longer than for those without
these systems in the following
road conditions.
(Continued)

Driving your vehicle

ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the ABS may result in a
longer stopping distance than for
vehicles equipped with a convention-
al brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
During that time, the ABS will go
through self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. We recom-
mend that you contact an authorised
HYUNDAI dealer as soon as possi-
ble.
WARNING
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, we recommend
that you contact your HYUNDAI
dealer as soon as possible.
CAUTION
When you drive on a road hav-
ing poor traction, such as an icy
road, and apply your brakes
continuously, the ABS will be
active continuously and the
ABS warning light ( ) may
illuminate. Pull your vehicle
over to a safe place and turn the
engine off.
Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with your ABS system.
We recommend that you contact
an authorised HYUNDAI dealer
as soon as possible.

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.

trol function does not operate any
more.
If the ignition switch is placed in the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically
turn on again.Indicator lights
When the ignition switch is placed in
the ON position, the ESC indicator
light illuminates, then goes off if the
ESC system is operating normally.
The ESC indicator light blinks when-
ever the ESC is operating.

your vehicle may have a malfunction
with the ESC system. When this
warning light illuminates we recom-
mend that the vehicle be checked by
an authorised HYUNDAI dealer as
soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button.

ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.
✽NOTICE
Turning the ESC OFF does not
affect ABS or standard brake sys-
tem operation.
CAUTION
Driving with varying tyre or
wheel sizes may cause the ESC
system to malfunction. When
replacing tyres, make sure they
are the same size as your origi-
nal tyres for this vehicle.
CAUTION
To prevent damage to the
transaxle:
• Do not allow wheel(s) of one
axle to spin excessively whilst
the ESC, ABS, and brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) exces-
sively whilst these lights are
displayed.
• When operating the vehicle on
a dynamometer, ensure the
ESC is turned off (ESC OFF
light illuminated).

Vehicle Stability Management
(if equipped)
Vehicle Stability Management (VSM)
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tyres can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
• The Electronic Stability Control
(ESC) is on.
• Vehicle speed is approximately
above 15 km/h on winding roads.
• Vehicle speed is approximately
above 20 km/h when the vehicle is
braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
✽NOTICE
The VSM does not operate when:
• Driving on a gradient or incline
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light ( ) is on.
WARNING
Take the following precautions
when using the Vehicle Stability
Management (VSM):
• ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
• Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.

Driving your vehicle

VSM OFF condition
To cancel VSM operation, press the
ESC OFF button. ESC OFF indicator
light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator
light will go out.Hill-Start Assist Control (HAC)
(if equipped)
The Hill-Start Assist Control (HAC)
prevents 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 releas-
es the brake when the accelerator
pedal is depressed or after 2 sec-
onds.
✽NOTICE
• The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral).
• The HAC activates even though
the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
WARNING
If ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a
malfunction with the VSM sys-
tem. When the warning light illu-
minates we recommend that the
vehicle be checked by an autho-
rised HYUNDAI dealer as soon
as possible.
WARNING
Always be ready to press the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.
CAUTION
Driving with varying tyre or
wheel sizes may cause the ESC
system to malfunction. When
replacing tyres, make sure they
are the same size as your origi-
nal tyres for this vehicle.

Driving your vehicle
Good braking practices 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 we recommend that you
call an authorised 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 tyre goes flat whilst you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead whilst 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 for-
ward.
WARNING
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to press
the brake pedal. Move the shift
lever into the 1st gear (for man-
ual transaxle vehicle) or P (Park,
for automatic transaxle vehicle)
position, then apply the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion.
Vehicles with the parking brake
not fully engaged are at risk of
moving inadvertently and caus-
ing injury to yourself or others.
