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. 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 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.

ESC operation
ESC ON condition
When the ignition switch is in the
ON position, the ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in operation,
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 ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.
• If Cruise Control was in use when
the ESC activates, Cruise Control
automatically disengages. Cruise
Control can be reengaged when the
road conditions allow. See “Cruise
Control (CC)” section in chapter 7 (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 stability 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/or
message “Traction Control disabled”
will illuminate. In this state, the traction
control function of ESC (engine
management) is disabled, but the
brake control function of ESC (braking
management) still operates.
• State 2
Press and hold the ESC OFF button
continuously for more than 3 seconds.
The ESC OFF indicator light and/or
message “Traction & 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 (braking management)
are disabled.
If the ignition switch is placed in the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.

Indicator lights
■ ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)
If the ignition switch is placed in the
LOCK/OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.
The ESC indicator light blinks whenever
the ESC is operating.
If the ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning light
illuminates we recommend that the
vehicle be checked by an authorized
HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
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
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 the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect ABS
or standard brake system operation.

Trailer stability assist (TSA)
Trailer stability assist is operated as a
vehicle stability control system. The
Trailer stability assist system stabilizes
the vehicle and trailer when the trailer
sways or oscillates. There are various
reasons making vehicle sway and
oscillate. In most cases it happens at
high speed however, if the trailer is
affected by crosswinds, buffeting, and
improper overloading, it may also be at
risk for sway.
Factors of swaying such as:
- High speed
- Str
ong crosswinds
- Improper o

verloading
- Sudden contr

olling of steering wheel
- Unev

en road
Trailer stability assist system
continuously analyzes the vehicle
and trailer instability. When the
Trailer stability assist system detects
some sway, the brakes are applied
automatically to help stabilize the vehicle
on the front wheel. However, if it is
not enough to stabilize, the brakes are
applied on all wheels automatically and
engine power is properly reduced. When
the vehicle is stable from swaying, trailer
stability assist system does not operate.
Downhill Brake Control (DBC)
ONX4060012
Downhill Brake Control assists the driver
to descend down a steep hill without
having to depress the brake pedal.
The system automatically applies the
brakes to maintain vehicle speed below
a certain speed and allows the driver
to concentrate on steering the vehicle
down hill.
The system is turned off whenever the
engine is turned off.
Press the button to turn on the system
and press the button again to turn it off.

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 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 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 we recommend that the
vehicle be 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
• 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 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 slow 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.

wly using engine braking
while driving downhill.
- Drive s

traight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.
OLMB053018
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Driving through water
• Try to avoid driving in deep standing
water. It may stall your engine and
clog your exhaust pipes.
• If you need to drive in water, stop
your vehicle, set the vehicle in Multi
Terrain mode and drive under 5 mph
(8 km/h).
• Do not change gear while driving in
water.
CAUTION
Always drive slowly in water. If you
drive too fast, water may get into the
engine compartment and wet the
ignition system causing your vehicle to
suddenly stop.

Additional driving conditions
• Become familiar with the off-road
conditions before driving.
• Always pay attention when driving off-
road and avoid dangerous areas.
• Drive slowly when driving in heavy
wind.
• Reduce vehicle speed when
cornering. The center of gravity
of AWD vehicles is higher than
conventional 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.
WARNING
Do hold the steering wheel tightly
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.
Emergency precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread patterns, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with 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.
In an emergency situation, a compact
spare tire (if equipped) or Tire Mobility
Kit (if equipped) may be used. But,
do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to avoid
failure of the differential or AWD system.
WARNING
Never start or run the engine while
an 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.
