WARNING
If the ABS warning light () is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your HYUNDAI
dealer as soon as possible.
NOTICE
When you drive on a road having 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 vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
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)
ONX4060011
Electronic Stability Control 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 management 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 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.

in an accident.
NOTICE
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
brie

fly to help free the vehicle if stuck in
snow or mud, by temporarily stopping
operation of ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:

[ 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 covered by the vehicle warranty.
Reduce engine power and do not
spin the wheel(s) excessively while
these lights are displayed.

[ When operating the vehicle on
a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect ABS
or standard brake system operation.

ONX4060013
All Wheel Drive (AWD) delivers engine
power to front and rear wheels for
maximum traction. AWD is useful when
extra traction is required, such as when
driving on, 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.
WARNING
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 cornering or
turning.

[ Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[ The risk of a rollover is greatly
increased if you lose control 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 t ravel lanes.
NOTICE

[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 slowly until you feel normal
braking return.

[ Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).

[ Always wash your vehicle thoroughly
after off road use, especially 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.

WARNING
If AWD warning light () stays on the
instrument cluster, your vehicle may
have a malfunction with the AWD
system. When the AWD warning light
(
) illuminates have vehicle checked by
an authorized HYUNDAI dealer as soon
as possible.
NOTICE

[ Maintain AWD Auto mode when
driving on roads in normal
conditions.

[ When driving under normal road
conditions (especially when
cornering) in AWD Lock mode, a
driver may find minor mechanical
vibration or noise, which is extremely
normal phenomenon, not a
malfunction. When AWD Lock mode
is released, such noise or vibration
will be immediately gone.
CAUTION
When driving on normal roads,
deactivate the AWD LOCK mode by
pushing the AWD LOCK button (AWD
LOCK indicator light goes off). Driving
on normal roads with the AWD LOCK
mode, especially, when cornering
may cause mechanical noise or
vibration. The noise and vibration will
disappear when the AWD LOCK mode is
deactivated. Prolonged driving with the
noise and vibration may damage some
parts of the power train.
NOTICE
When the AWD LOCK mode is
deactivated, a sensation may be felt as
the driving power is delivered entirely
to the front wheels.
Auto All Wheel Drive mode
(normal driving)
If the AWD system determines there is a
need for four wheel drive, the engine's
driving power is distributed to all four
wheels automatically.
For safe AWD operation
Before driving

[Mak
e sure all passengers are wearing
seat belts.

[ Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.

Driving on snow-covered or icy roads

[ S
tart off slowly by applying the
accelerator pedal gently.

[ Use snow tires or tire chains.

[ Keep sufficient distance between your
vehicle and the vehicle in front of you.

[ Apply engine braking during
deceleration by using the paddle
shifter (manual shift mode) and
manually selecting a lower gear.

[ Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
Information
When using Snow Tires, mount them on
all four wheels.
If a full set of chains is not available for
an AWD vehicle when using tire chains,
chains may be installed on the front wheels
only.
For more details on Snow Tires and Tire
Chains, refer to "Winter Driving" section
later in this chapter.
Driving in sand or mud

[Maintain slo
w and constant speed.

[ Use tire chains driving in mud if
necessary.

[ Keep sufficient distance between your
vehicle and the vehicle in front of you.

[ Reduce vehicle speed and always
check the road condition.

[ Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent getting stuck.
NOTICE
When the vehicle is stuck in snow, sand
or mud, place a nonslip material under
the drive wheels to provide traction
OR slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle.
However, avoid running the engine
continuously at high RPM, doing so may
damage the AWD system.
