Driving your vehicleWhen you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car 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 prob-
lem with your ABS system.
Contact an authorized HYUNDAI
dealer as soon as possible.
Information
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 malfunctioning.
Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
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.
i
NOTICE
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, contact your
HYUNDAI dealer as soon as
possible.

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. After both
lights go off, the ESC is enabled.
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 corre-
sponding 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 dis-
engages. The Cruise Control can
be reengaged when the road con-
ditions allow. See "Cruise Control
System" later in this chapter. (if
equipped)
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.
ESC OFF condition
To cancel ESC operation :
State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.

Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction and Stability
Control disabled" illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically turn
on again.
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
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.WARNING

Indicator lights
When the ignition switch is placed to
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.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off.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 wheels and tires
installed.
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 while driving, press
the ESC OFF button while driving on
a flat road surface.
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking 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) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
NOTICENOTICE
■ ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off while the ESC indicator
light is blinking or you may lose
control of the vehicle resulting in
an accident.
WARNING

5-40
Driving your vehicle
The All Wheel Drive (AWD) system
delivers engine torque to both the
front and rear wheels for extra trac-
tion. AWD is useful when maximum
traction is required on slippery,
muddy, wet, or snow-covered roads.
Occasional off-road use such as
established unpaved roads and trails
are OK. It is always important that
the driver carefully reduces the
speed to a level that does not exceed
the safe operating speed for those
conditions. Do not drive in water if the level
is higher than the bottom of the
vehicle.
Check your brake condition once you are out of mud or
water. Depress the brake pedal
several times as you move slow-
ly until you feel normal braking
return.
Shorten your scheduled mainte- nance interval if you drive in off-
road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
in chapter 7).
Always wash your vehicle thor- oughly after off road use, espe-
cially the bottom of the vehicle.
Be sure to equip the vehicle with four tires of the same size and
type.
Make sure that a full time AWD vehicle is towed by a flat bed
tow truck.

To reduce the risk of SERIOUS
INJURY or DEATH:
Do not drive in conditions that
exceed the vehicles intended
design such as challenging
off-road conditions.
Avoid high speeds when cor-
nering or turning.
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of a rollover is great-
ly increased if you lose con-
trol of your vehicle at highway
speeds.
Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

Driving your vehicle
Additional driving conditions
Become familiar with the off-roadconditions before driving.
Always pay attention when driving off-road and avoid dangerous
areas.
Drive slowly when driving in heavy wind.
Reduce vehicle speed when cor- nering. The center of gravity of
AWD vehicles is higher than con-
ventional 2WD vehicles, making
them more likely to roll over when
you rapidly turn corners.
Always hold the steering wheel firmly when you are driving off-
road.
Emergency Precautions
Tires
Do not use a tire and wheel package
with a different size and type from
the one originally installed on your
vehicle. It can affect the safety and
performance of your vehicle, which
could lead to steering failure or
rollover causing serious injury.
When replacing the tires, be sure to
equip all four tires with the tire and
wheel of the same size, type, tread,
brand and load-carrying capacity. If
you equip your vehicle with any
tire/wheel combination not recom-
mended by HYUNDAI for off-road
driving, you should not use these
tires for highway driving.
Do not grab the inside of the
steering wheel when you are
driving off-road. You may hurt
your arm by a sudden steering
maneuver or from steering wheel
rebound due to an impact with
objects on the ground. You could
lose control of the steering wheel
which may lead to serious injury
or death.
WARNING
Never start or run the engine
while a full-time AWD vehicle is
raised on a jack. The vehicle can
slip or roll off of a jack causing
serious injury or death to you or
those nearby.
WARNING

The ISG system helps reduce fuel
consumption and exhaust gas emis-
sions by automatically shutting down
the engine, when the vehicle is at a
standstill (i.e. red stop light, stop
sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To Activate the ISG System
Prerequisite for activation

FCA Warning Message and
System Control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward Collision
Warning include Early or Later initial
warning time.
Collision Warning (First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- Your vehicle speed may deceleratemoderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision.
- If you select "Warning Only", the FCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the brake
directly because the FCA system
do not control the brake.
Emergency Braking(Second warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- The FCA system limitedly controls
the brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.
