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:
Electronic Stability Control (ESC) is on.
When operating
When you apply your brakes under
conditions which may 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 EPS (Electric power steering)
warning light (
) is on or blinks.

VSM OFF condition
To cancel VSM operation, press the ESC
OFF button. ESC OFF indicator light (
)
will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator light
will go out.
WARNING
If the ESC indicator light () or EPS
warning light () stays illuminated
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates
we recommend that the vehicle be
checked by an authorized HYUNDAI
dealer as soon as possible.
NOTICE
Driving with wheels and tires with
different sizes may cause the VSM
system to malfunction. Before replacing
tires, make sure all four tires and wheels
are the same size. Never drive the
vehicle with different sized tires and
wheels installed.
Hill-Start Assist Control (HAC)
Hill-Start Assist Control helps prevent
the vehicle from rolling backwards
when starting a vehicle from a stop
on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases when the
accelerator pedal is depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off
an incline. The HAC activates only for
approximately 2 seconds.
Information
• HAC does not operate when the shift
button is in P (Park) or N (Neutral).
• HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when
ESC does not operate normally.

Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift button into the P
(Park) position, then apply the parking
brake, and set the ignition switch in the
LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal. If the braking action does not
return to normal, stop as soon as it is safe
to do so and we recommend that you
call an authorized HYUNDAI dealer for
assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

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 up or down hills
• Driving uphill
- Bef

ore starting off, check if it is
possible to drive uphill.
- Drive as s

traight as possible.
• Driving downhill
- Do not change gear while driving
do

wnhill. Select gear before driving
downhill.
- Drive as slo

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.

Hazardous driving conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:
• Drive cautiously and maintain a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.
• Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire
or other damage. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tires
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
