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.

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 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.

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.

Transfer mode Selection button Indicator light Description
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.

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.
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 driv-
ing downhill.
- Drive slowly using engine braking
while driving downhill.
- Drive straight as possible.
OLMB053017
Exercise extreme caution when
driving up or down steep hills.
The vehicle may flip over
depending on the grade, the ter-
rain, and the trail conditions.
WARNING
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
AWD system.
CAUTION

5-48
Driving your vehicle
Driving through water
Try to avoid driving in deep stand-
ing water. It may stall your engine
and clog your exhaust system.
If you need to drive in water, stop
your vehicle, set the vehicle in
AWD LOCK mode and drive under
5 mph (8 km/h).
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 cor-
nering. The center of gravity of
AWD vehicles is higher than con-
ventional 2WD vehicles, making
them more likely to roll over when
you rapidly turn corners.
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
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

A full-time AWD vehicle should not
be tested on a 2WD roll tester. If a
2WD roll tester must be used, per-
form the following procedure:
1. Check the tire pressures recom-
mended for your vehicle.
2. Place the front wheels on the roll
tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the rear wheels on the tem-
porary free roller as shown in the
illustration.
OTLE058117Roll Tester (Speedometer)
Temporary Free Roller
Never engage the parking
brake while performing the
test.
When the vehicle is lifted up,
do not operate the front and
rear wheel separately. All four
wheels should be operated.
CAUTION

Driving your vehicle
[A] : Blind spot area
[B] : Closing at high speed
The Blind-Spot Collision Warning
(BCW) system uses radar sensors in
the rear bumper to monitor and warn
the driver of an approaching vehicle
in the driver's blind spot area.
The system monitors the rear area of
the vehicle and provides information
to the driver with an audible alert and
an indicator on the outer side view
mirrors.(1) Blind-Spot Collision Warning
(BCW)
The Blind-Spot Collision Warning
(BCW) range varies relative to
vehicle speed. Note that if your
vehicle is traveling much faster
than the vehicles around you, the
warning will not occur.
(2) BCW : Closing at high speed
The BCW-Closing at high speed
feature will alert you when a vehi-
cle is approaching in an adjacent
lane at a high rate of speed. If the
driver activates the turn signal
when the system detects an
oncoming vehicle, the system
sounds an audible alert.
The time of alert (warning signal)
varies according to the speed dif-
ference between you and the
approaching vehicle.
(3) RCCW (Rear Cross-Traffic
Collision Warning)
The RCCW feature monitors
approaching cross traffic from the
left and right side of the vehicle
when your vehicle is in reverse.The feature will operate when the
vehicle is moving in reverse
below about 6 mph (10 km/h). If
oncoming cross traffic is detected
a warning chime will sound. The
time of alert varies according to
the speed difference between you
and the approaching vehicle.
