ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
When the ESC activates, the
engine may not respond to the
accelerator as it does under rou-
tine conditions. If the Cruise Control was in use
when the ESC activates, the
Cruise Control automatically disen-
gages. The Cruise Control can be
reengaged when the road condi-
tions allow. See "Cruise Control
System" later in this chapter. (if
equipped)
When moving out of the mud or
driving on a slippery road, the
engine RPM (revolutions per
minute) may not increase even if
you press the accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem. Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

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 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.
WARNING

5-44
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.

5-46
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.

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.
