The Four Wheel Drive (4WD)
System delivers engine power to all
front and rear wheels for maximum
traction. 4WD is useful when extra
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.
FOUR WHEEL DRIVE (4WD) (IF EQUIPPED)
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.

4WD operation
In the 4WD LOCK mode, the system is deactivated when vehi-
cle speed is over 37 mph (60 km/h) and the mode is shifted to
4WD AUTO mode. If the vehicle speed slows down to 37 mph
(60 km/h), the mode shifts back to the 4WD LOCK mode.
If 4WD Lock is activated, the driving force distribution in the
cluster is not displayed.
Use this mode when driving up or down steep inclines, driving
off-road, driving on sandy and muddy roads, etc. to maximise
traction
(not illuminated)
Transfer mode Selection button Indicator light Description
In the 4WD AUTO mode, under normal operating conditions,
the vehicle operates similar to conventional 2WD vehicles. If the
system determines there is a need for four wheel drive, the
engine’s driving power is distributed to all four wheels automat-
ically.
Use this mode when driving on normal roads.
If you select the "Driving force distribution" in the cluster,
Driving force distribution (4WD) state is displayed.

Driving your vehicle
When the 4WD LOCK mode is
deactivated, a sensation may be
felt as the driving power is deliv-
ered entirely to the front wheels.
For safe 4WD operation
Before driving
• Make sure all passengers are
wearing seat belts.
• Sit upright and closer to the steer-
ing wheel than usual. Adjust the
steering wheel to a position com-
fortable for you to drive.
Driving on snow-covered or icy
roads
• Start off slowly by applying the
accelerator pedal gently.
• Use snow tyres or tyre chains.
• Keep sufficient distance between
your vehicle and the vehicle in front
of you.
• Use engine braking during deceler-
ation.
• Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.
Driving in sand or mud
• Maintain slow and constant speed.
• Use tyre 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 driving on normal roads,
deactivate the 4WD LOCK mode
by pushing the 4WD LOCK but-
ton (4WD LOCK indicator light
goes off). Driving on normal
roads with the 4WD LOCK
mode, especially, when corner-
ing may cause mechanical
noise or vibration. The noise
and vibration will disappear
when the 4WD LOCK mode is
deactivated. Prolonged driving
with the noise and vibration
may damage some parts of the
power train.
CAUTION
When the vehicle is stuck in
snow, sand or mud, place a non-
slip material under the drive
wheels to provide traction OR
slowly spin the wheels in for-
ward 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
4WD system.
CAUTION

Driving up or down hills
• Driving uphill
- Before starting off, check if it is
possible to drive uphill.
- Drive as straight as possible.
• Driving downhill
- Do not change gear whilst driving
downhill. Select gear before driv-
ing downhill.
- Drive slowly using engine braking
whilst driving downhill.
- Drive straight as possible.
Driving through water
• Try to avoid driving in deep stand-
ing 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
4WD LOCK mode and drive under
5 mph (8 km/h).
• Do not change gear whilst driving
in water.
OLMB053017
Exercise extreme caution driv-
ing up or down steep hills. The
vehicle may flip depending on
the grade, terrain and water/
mud conditions.
WARNING
OLMB053018
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.
WARNING
Always drive slowly in water. If
you drive too fast, water may
get into the engine compart-
ment and wet the ignition sys-
tem causing your vehicle to
suddenly stop.
CAUTION

Driving your vehicle
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 cor-
nering. The centre of gravity of
4WD 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 firm-
ly when you are driving off-road.
Emergency precautions
Tyres
Do not use tyre and wheel with dif-
ferent size and type from the one
originally installed on your vehicle. It
can affect the safety and perform-
ance of your vehicle, which could
lead to steering failure or rollover
causing serious injury.
When replacing the tyres, be sure to
equip all four tyres with the tyre and
wheel of the same size, type, tread,
brand and load-carrying capacity. If
you equip your vehicle with any
tyre/wheel combination not recom-
mended by HYUNDAI for off-road
driving, you should not use these
tyres for highway driving.
Towing
4WD vehicles must be towed with a
wheel lift and dollies or flatbed equip-
ment with all the wheels off the
ground. For more information, refer
to "Towing" in chapter 6.
Dynamometer testing
A full-time 4WD vehicle must be test-
ed on a special four wheel chassis
dynamometer.
Do not grab the inside of the
steering wheel when you are
driving off-road. You may hurt
your arm by a sudden steering
manoeuvre or from steering
wheel rebound due to an impact
with objects on the ground. You
could lose control of the steer-
ing wheel which may lead to
serious injury or death.
WARNING
Never start or run the engine
whilst a full-time 4WD 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.

Rollover
As with other Sports Utility
Vehicle (SUV), failure to operate
this vehicle correctly may result
in loss of control, an accident or
vehicle rollover.
•Utility vehicles have a signifi-
cantly higher rollover rate
than other types of vehicles.
•Specific design characteris-
tics (higher ground clearance,
narrower track, etc.) give this
vehicle a higher centre of
gravity than ordinary vehicles.
•A SUV is not designed for cor-
nering at the same speeds as
conventional vehicles.
•Avoid sharp turns or abrupt
manoeuvres.
•In a rollover crash, an unbelt-
ed person is significantly
more likely to die than a per-
son wearing a seat belt. Make
sure everyone in the vehicle is
properly buckled up.
WARNING
Your vehicle is equipped with
tyres designed to provide safe
ride and handling capability. Do
not use a size and type of tyre
and wheel that is different from
the one that is originally
installed on your vehicle. It can
affect the safety and perform-
ance of your vehicle, which
could lead to steering failure or
rollover and serious injury.
When replacing the tyres, be
sure to equip all four tyres with
the tyre and wheel of the same
size, type, tread, brand and
load-carrying capacity. If you
nevertheless decide to equip
your vehicle with any tyre/wheel
combination not recommended
by HYUNDAI for off road driv-
ing, you should not use these
tyres for highway driving.
WARNING
Jacked vehicle
Whilst a full-time 4WD vehicle is
being raised on a jack, never
start the engine or cause the
tyres to rotate.
There is a danger that rotating
tyres touching the ground could
cause the vehicle to fall off the
jack and to jump forward or
rearward.

The ISG system is to reduce the fuel
consumption by automatically shut-
ting down the engine, when the vehi-
cle 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
