Vehicle Stability Management
(if equipped)
Vehicle Stability Management (VSM)
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tyres 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 15 km/h (9 mph) on curve
roads.
Vehicle speed is approximately
above 20 km/h (12 mph) 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 in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electronic Power Steering)
warning light ( ) is on.
VSM OFF condition
To cancel the VSM operation, press
the ESC OFF button. ESC OFF indi-
cator light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator
light will go out.
Driving with varying tyre or wheel
sizes may cause the ESC system
to malfunction. When replacing
tyres, make sure they are the
same size as your original tyres
for this vehicle.
NOTICEi
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
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a
malfunction with the VSM sys-
tem. When the warning light illu-
minates we recommend that the
vehicle be checked by an autho-
rised HYUNDAI dealer as soon
as possible.

Hill-Start Assist Control (HAC)
(if equipped)
A vehicle has the tendency to slide
rearwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding rearwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed
Information
• The HAC does not operate when the
shift lever is in P (Park) or N
(Neutral)
• The HAC activates even when the
ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC is not operationg nor-
mally.
Downhill Brake Control (DBC)
(if equipped)
The Downhill Brake Control (DBC)
supports the driver come down a
steep hill without depressing the
brake pedal.It slows down the vehicle under 8
km/h (for automatic transmission/dual
clutch transmission) or 8 km/h (for
manual transmission vehicles) and
lets the driver concentrate on steer-
ing the vehicle.
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
i
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
WARNING

DBC operation
The DBC may not deactivate on
steep inclines even though the
brake or accelerator pedal is
depressed.
Do not turn on the DBC when
driving with shift lever in 3
rdgear
(and above) for vehicles with
manual transmission. The
engine may stop if the DBC sys-
tem is activated.
The DBC does not operate when:
- The shift lever is in P (Park).
- The ESC is activated.

Low Vacuum Assist (LVA)
(if equipped)
Low Vacuum Assist (LVA) amplifies
the hydraulic brake force to assist the
driver under low or temporarily low
engine vacuum. You may hear a
motor running sound and feel a slight
vibration in the brake pedal like ABS
operating. This indicates that the
Supplemental Brake Assist system is
working to maintain braking power.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver following your vehi-
cle, by blinking the stop lights, whilst
sharply and severely braking.
The system is activated when:
The vehicle suddenly stops (the
deceleration power exceeds 7
m/s
2, and the driving speed
exceeds 55 km/h).
The ABS is activated.
The hazard warning flasher automat-
ically turns ON; after blinking the
stop lights, when driving speed is
below 40 km/h , when the ABS is
deactivated, and when a sudden
braking situation has stopped.
The hazard warning flasher turns
OFF, when the driving speed
exceeds 10 km/h after a complete
stop. The hazard warning flasher
turns OFF, when the vehicle drives at
a low speed for a certain period of
time. The driver can manually turn
OFF the hazard warning flasher by
pressing the button.
Information
The Emergency Stop Signal (ESS) sys-
tem will not activate, when the hazard
warning flasher blinks.
i
Low Vacuum Assist (LVA) will
not prevent accidents due to
improper or dangerous driving
manoeuvres.

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 we recommend that you
call an authorised 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 tyre goes flat whilst you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead whilst 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.
The Four Wheel Drive (4WD)
System delivers engine power to all
front and rear wheels for maximum
traction. 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 P (Park) posi-
tion, apply the parking brake,
and place the Engine Start/Stop
button in the OFF position.
Vehicles without the parking
brake fully engaged are at risk
of moving inadvertently and
causing injury to yourself or
others.

4WD is useful when extra traction is
required on roads such 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 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 tyres and wheels of the
same size and type.
Make sure that if a full-time 4WD
vehicle requires towing, it is
towed by a flat bed tow truck.NOTICE
To reduce the risk of SERIOUS
INJURY or DEATH:
Do not drive in conditions that
exceed the vehicle's 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.
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

Maintain 4WD Auto mode when
driving on roads in normal con-
ditions.
When driving under normal road
conditions (especially when cor-
nering) in 4WD Lock mode, a
driver may find minor mechani-
cal vibration or noise, which is
extremely normal phenomenon,
not a malfunction. When 4WD
Lock mode is released, such
noise or vibration will be imme-
diately gone.
When the 4WD LOCK mode is
deactivated, a sensation may be
felt as the driving power is deliv-
ered entirely to the front wheels.
For safe 4WD 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 which
is comfortable for you to drive.
Driving on snow-covered or icy
roads
Start off slowly by applying the
accelerator pedal gently.
Use snow tyres or tyre chains.
Keep sufficient distance between
your vehicle and the vehicle in front
of you.
Use engine braking during deceler-
ation.
Avoid speeding, rapid acceleration,
sudden brake applications, and
sharp turns to prevent skids.
NOTICE
NOTICE
When driving on normal roads,
deactivate the 4WD LOCK mode
by pushing the 4WD LOCK but-
ton (4WD LOCK indicator light
goes off). Driving on normal
roads with the 4WD LOCK
mode, especially, when corner-
ing may cause mechanical
noise or vibration. The noise
and vibration will disappear
when the 4WD LOCK mode is
deactivated. Prolonged driving
with the noise and vibration
may damage some parts of the
power train.
CAUTION

5-70
Driving your vehicle
Driving in sand or mud
Maintain slow and constant speed.
Use tyre chains when 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 whilst driving
downhill. Select a gear before
driving downhill.
- Drive slowly using engine braking
whilst driving downhill.
- Drive as straight as possible. 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
4WD system.
CAUTION
OLMB053017
Exercise extreme caution driv-
ing up or down steep hills. The
vehicle may flip depending on
the grade, terrain and water/
mud conditions.
