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 case it happens at high
speed however, if the trailer is affected
by crosswinds, buffeting, and improper
overloading, it may also be a risk of sway.
Factors of swaying such as:
- High speed
-Strong crosswinds
-Improper overloading
-Sudden controlling of steering wheel
-Uneven 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 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.

ALL WHEEL DRIVE (AWD) (IF EQUIPPED)
„„Type A
ONX4060013
„„Type B
ONX4E060031
The All Wheel Drive (AWD) System
delivers engine power to all front and
rear wheels for maximum traction. AWD
is useful when extra traction is required
on roads such 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.
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" in
chapter 7).
• 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 tow ed 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. Prolong 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.
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.
• Use engine braking during
deceleration.
• Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.
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.
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 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.

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 while driving
downhill. Select gear before driving
downhill.
-Drive as slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
depending on the grade, terrain and
water/ 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 AWD
LOCK mode and drive under 8 km/h
(5 mph).
• Do not change gear while driving in
water.
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.

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.
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 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.

WINTER DRIVING
The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
a flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
We recommend that you use snow tires
when road temperature is below 45°F
(7°C). Refer to the below chart, and
mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle,
make sure to use the same Inflation
pressure as the original tires. Mount
snow tires on all four wheels to balance
your vehicle’s handling in all weather
conditions. The traction provided by
snow tires on dry roads may not be as
high as your vehicle’s original equipment
tires. Check with the tire dealer for
maximum speed recommendations.

Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.47 in.
(12mm) thick to prevent damage to
the chain’s connection.
Winter precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not
sure about a type of winter weight oil,
we recommend that you consult an
authorized HYUNDAI dealer.

Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 8. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized HYUNDAI
dealer, and most vehicle accessory
outlets. Do not use engine coolant or
other types of anti-freeze solution, to
prevent any damage to the vehicle paint.Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
engine compartment
Putting objects or materials in the engine
compartment may cause an engine
failure or combustion, because they may
block the engine cooling. Such damage
will not be covered by the manufacturer’s
warranty.
