During that time, 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 recommend that you contact an
authorized HYUNDAI dealer as soon as
possible.
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 authorized
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, 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. We recommend
that you contact an authorized
HYUNDAI dealer as soon as possible.
Information
When you jump start your vehicle because
of a drained battery, the ABS (When you jump start your vehicle because )
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)
OTM060013
Electronic Stability Control 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. ESC will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on wet
surfaces can result in severe accidents.

when ESC is turned off.
WARNING
When ESC is blinking, this indicates ESC
is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn ESC off while
the ESC indicator light is blinking or you
may lose control of the vehicle resulting
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
briefly 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
ESC is turned off (ESC OFF light
illuminated).
Information
Turning ESC off does not affect ABS or
standard brake system operation.

Four Wheel Drive (4WD) delivers engine
power to front and rear wheels for
maximum traction. 4WD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
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 travel 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 4WD
vehicle is towed by a flat bed tow
truck.

For safe 4WD operation
Before driving
• Make 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
• Start 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 4WD 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.
CAUTION
Mud or snow
If one of the front or rear wheels
begins to spin in mud, snow, etc. the
vehicle can sometimes be driven out by
engaging the accelerator pedal further;
however avoid running the engine
continuously at high rpm because doing
so could damage the AWD system.
Driving in sand or mud
• Maintain slow and constant speed.
Operate the accelerator pedal slowly
to ensure safe driving (wheel-slip
prevention).
• 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.
• When the vehicle is stuck in snow,
sand or mud, the tires may not
operate.
• This is to protect the transmission and
not a malfunction.
NOTICE
Moving the vehicle forcibly to get out
of mud or sand can cause damage/
overheat of the engine or damage/
breakdown of the transmission,
differential or 4WD system as well as
damage to tires. If excessive wheel slip
occurs after entering a sandy/muddy
road, the vehicle may fall into the sand/
mud. When it happens, put a stone or
a tree branch under the tire, and then
try to pull out the vehicle, or try to get it
unstuck by repeatedly moving forwards
and backwards.

a wheel lift and dollies or flatbed
equipment with all the wheels off the
ground. For more details, refer to
"Towing" section in chapter 8.
Vehicle inspection
• If the vehicle needs to be operated on
a vehicle lift do not attempt to stop
any of the four wheels from turning.
This could damage the 4WD system.
• Never engage the parking brake while
running the engine on a car lift. This
may damage the 4WD system.
Dynamometer testing
An 4WD vehicle must be tested on a
special four wheel chassis dynamometer.
OTM060016L[A] : Roll tester (Speedometer),
[B] : Temporary free roller
An 4WD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll tester
must be used, perform the following
procedure:
1.
Check the tire pr

essures
recommended for your vehicle.
2.
Place the rear wheels on the r

oll tester
for a speedometer test as shown in
the illustration.
3.
Release the parking br

ake.
4.
Place the fron

t wheels on the
temporary free roller as shown in the
illustration.
WARNING
Keep away from the front of the vehicle
while the vehicle is in gear on the
dynamometer. The vehicle can jump
forward and cause serious injury or
death.
Reducing the risk of a rollover
Your multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them
capable of performing in a wide variety
of off-road applications. The specific
design characteristics give them a higher
center of gravity than ordinary vehicles
making them more likely to roll over if
you make abrupt turns. Utility vehicles
have a significantly higher rollover rate
than other types of vehicles. Due to this
risk, driver and passengers are strongly
recommended to buckle their seat belts.
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.
There are steps that a driver can make
to reduce the risk of a rollover. If at all
possible, avoid sharp turns or abrupt
maneuvers, do not load your roof rack
with heavy cargo, and never modify your
vehicle in any way.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

possible, avoid sharp turns or abrupt
maneuvers, do not load your vehicle
with heavy cargo on the roof, and never
modify your vehicle in any way.
WARNING
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles. To prevent rollovers or loss of
control:
• Take corners at slower speeds than
you would with a passenger vehicle.
• Avoid sharp turns and abrupt
maneuvers.
• Do not modify your vehicle in any
way that you would raise the center
of gravity.
• Keep tires properly inflated.
• Do not carry heavy cargo on the roof.
WARNING
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Make sure
all passengers are wearing their seat
belts.
