Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management :

[ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.

[ Never drive too fast for the road
conditions. VSM system will not
prevent accidents. Excessive speed
in bad weather, on slippery and
uneven roads can result in severe
accidents.
VSM operation
VSM ON condition
VSM operates when:
Electr

onic Stability Control (ESC) is on.
When operating
When you apply your brakes under
conditions which ma
y activate ESC, you
may hear sounds from the brakes, or feel
a corresponding sensation in the brake
pedal. This is normal and it means your
VSM is active.
Information
The VSM does not operate when:

[ Driving on a banked road such as
gradient or incline.

[ Driving in reverse.

[ The ESC OFF indicator light is on.

[ The MDPS (Motor Driven Power
Steering) warning light (
) is on or
blinks.

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
- 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 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.

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.

Emergency Towing
„Front
ONX4080019
„Rear
ONX4H080002
If towing is necessary, have it done by
an authorized HYUNDAI dealer or a
commercial tow truck service.
If a towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle with a cable or chain. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds. Also, the
wheels, axles, power train, steering and
brakes must all be in good condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:

[Place the ignition switch in the ACC
position so the steering wheel is not
locked.

[ Place the shift button in N (Neutral).

[ Release the parking brake.

[ Depress the brake pedal with more
force than normal as you will have
reduced braking performance.

[ More steering effort will be required
because the power steering system
will be disabled.

[ Use a vehicle heavier than your own to
tow your vehicle.

[ The drivers of both vehicles should
communicate with each other
frequently.

[ Before emergency towing, check that
the hook is not broken or damaged.

[ Fasten the towing cable or chain
securely to the hook.

[ Do not jerk the hook. Apply steady
and even force.
