Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control
(ESC) is on.
Vehicle speed is approximately
above 9 mph (15 km/h) on curve
roads.
Vehicle speed is approximately
above 12 mph (20 km/h) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
Information
The VSM does not operate when:
• Driving on bank road such as gradi-
ent or incline.
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light ( ) is on.
i
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
WARNING

Driving your vehicle
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.
Driving with wheels and tires with dif-
ferent sizes may cause the ESC sys-
tem 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)
The Hill-Start Assist Control (HAC)
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 releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral)
The HAC activates even though
the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
Downhill Brake Control (DBC)
The Downhill Brake Control (DBC)
feature assists the driver to descend
down a steep hill without having to
depress the brake pedal.
NOTICE
If ESC indicator light ( ) or EPS
warning light ( ) stays on, your
vehicle may have a malfunction
with the VSM system. When the
warning light illuminates, have
your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC activates
only for approximately 2 seconds.

The system automatically applies the
brakes to maintain the vehicle speed
below 5 mph (8 km/h) and allows the
driver to concentrate on steering the
vehicle down hill.
The DBC defaults to the OFF
position whenever the ignition
switch is placed in the ON posi-
tion.
Noise or vibration may occur
from the brakes when the DBC is
activated.
The rear stop light comes on
when DBC is activated.
NOTICE
Always turn off the DBC on nor-
mal roads. The DBC might acti-
vate inadvertently from the stand-
by mode when driving through
speed bumps or making sharp
curves.
WARNING
Standby
Press the DBC button when vehicle speed is under
25 mph (40 km/h). The DBC system will turn ON and
enter the standby mode.
The system does not turn ON if vehicle speed is over
25 mph (40 km/h).
In the standby mode, if vehicle speed is under 22 mph
(35 km/h) while driving down a steep hill, the DBC will
activate automatically.
In the activated mode, the DBC will temporarily deacti-
vate under the following conditions:


The brake pedal or accelerator pedal is depressed.
If the above conditions are not met, the DBC will auto-
matically activate again.
The DBC will turn OFF under the following conditions:

The DBC may not deactivate on
steep inclines even though the
brake or accelerator pedal is
depressed.
The DBC does not operate
when:
- The shift lever is in P (Park).
- The ESC is activated.
Good Braking Practices
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, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and 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 driv-
ing, 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 for-
ward.
NOTICE
If the DBC red indicator light
illuminates, the system may
have overheated or have mal-
functioned. When the warning
light illuminates even though
the DBC system has cooled off,
have your vehicle checked by
an authorized HYUNDAI dealer
as soon as possible.
WARNING
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the ignition
switch in the OFF position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

The All Wheel Drive (AWD) system
delivers engine torque to both the
front and rear wheels for extra trac-
tion.
AWD is useful when maximum trac-
tion 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.

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.
WARNING

Driving your vehicle
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 slow-
ly until you feel normal braking
return.
Shorten your scheduled mainte-
nance 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 thor-
oughly after off road use, espe-
cially 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.
NOTICEIn the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

AWD operation
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 your vehicle checked by an authorized
HYUNDAI dealer as soon as possible.
WARNING
The main goal of AWD Lock mode is to allow a driver to max-
imize the vehicle’s traction under extreme driving conditions
such as unpaved off-road, sandy roads, and muddy roads.
AWD Lock mode is in operation only when a vehicle travels
at 60 km/h or less. When traveling at 60 km/h or faster, the
mode will switch to AWD Auto.
When AWD Lock mode illuminates, the cluster does not dis-
play the front/rear wheel traction force distribution status.

AWD Auto is used when driving on roads in normal condi-
tions, roads in urban areas, and on highways.
All wheels are in operation when a vehicle travels at a con-
stant speed. Required tractions applying on front and rear
wheels vary depending on road driving conditions and driv-
ing conditions, which will be automatically controlled by the
computing system.
When the cluster's AWD Auto display mode is selected, the
cluster displays the status of how four wheels’ traction forces
are distributed.

Driving your vehicle
Maintain AWD Auto mode when
driving on roads in normal con-
ditions.
When driving under normal road
conditions (especially when cor-
nering) in AWD Lock mode, a
driver may find minor mechani-
cal vibration or noise, which is
extremely normal phenomenon,
not a malfunction. When AWD
Lock mode is released, such
noise or vibration will be imme-
diately gone.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 dam-
age some parts of the power train.
Information
When the AWD LOCK mode is deac-
tivated, 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 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 tires or tire chains.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Apply engine braking during decel-
eration by switching the gear shift
lever to Manual Shift Mode and
manually selecting a lower gear.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.
