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. The VSM does not operate when:
Driving on bank road such as
gradient or incline.
Driving rearward.
ESC OFF indicator light is on.
EPS (Electric Power Steering) warning light ( ) is on.
NOTICE
5Take 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 severeaccidents.
WARNING

5-38
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 indicatorlight 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 sizedtires 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.
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.
WARNING

Driving your vehicle
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. 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

The DBC may not deactivate onsteep inclines even though the brake or accelerator pedal isdepressed.
The DBC does not operate when:
- The shift lever is in P (Park).
- The ESC is activated.
NOTICE
Driving your vehicle
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.

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, butconstant 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.
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.
WARNING

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
traction 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. 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 brakingreturn.
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.NOTICE

Driving your vehicle
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 highwayspeeds.
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.
WARNING

5-44
When the AWD LOCK mode is
deactivated, a sensation may be
felt as the driving power is deliv-
ered entirely to the front wheels.
For safe AWD operation
Before driving
Make sure all passengers arewearing 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 theaccelerator 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 ifnecessary.
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.
NOTICE
Driving your vehicle
When driving on normal roads,
deactivate the AWD LOCK mode
by pushing the AWD LOCK but-
ton (AWD LOCK indicator light
goes off). Driving on normal
roads with the AWD LOCK
mode, especially, when corner-
ing may cause mechanical
noise or vibration. The noiseand vibration will disappear
when the AWD LOCK mode is
deactivated. Prolong drivingwith the noise and vibration
may damage some parts of the
power train.
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 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

Emergency precautions
Tires
Do not use a tire and wheel package
with a different size and type from
the one originally installed on your
vehicle. It can affect the safety and
performance of your vehicle, which
could lead to steering failure or
rollover causing serious injury.
When replacing the tires, be sure to
equip all four tires with the tire and
wheel of the same size, type, tread,
brand and load-carrying capacity. If
you equip your vehicle with anytire/wheel combination not recom-
mended by HYUNDAI for off-road
driving, you should not use these
tires for highway driving.
Towing
AWD vehicles must be towed with awheel lift and dollies or flatbed equip-ment with all the wheels off the
ground. For more information, refer
to "Towing" in chapter 6.
Dynamometer testing
A full-time AWD vehicle must be test-
ed on a special four wheel chassis
dynamometer.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.
5
Never start or run the engine
while a full-time AWD vehicle is
raised on a jack. The vehicle can
slip or roll off of a jack causing
serious injury or death to you or
those nearby.

Prerequisite for activation
The AEB gets ready to be activated, when the AEB is selected on the
LCD display, and when the followingprerequisites are satisfied.
- The ESC is activated.
- To enable the system to detectpedestrians ahead, the vehicle
driving speed must be between 5 -40 mph (8 - 65 km/h).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 5 - 110mph (8 - 180 km/h).
When traveling above 50 mph (80km/h), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels.
Also, it controls the brakes in accor-
dance with the collision risk levels.

The AEB automatically acti-
vates upon placing the igni-
tion switch to the ON position.
The driver can deactivate the
AEB by canceling the system
setting on the LCD display.
The AEB automatically deacti-
vates upon canceling the
ESC. When the ESC is can-
celed, the AEB cannot be acti-
vated on the LCD display.
