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) warn- ing 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.

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
different sizes may cause the ESC
system 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.
NOTICE
NOTICE
If ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a mal-
function with the VSM system.
When the warning light illumi-
nates have the vehicle checked
by an authorized HYUNDAI deal-
er 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
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.
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 Engine
Start/Stop button 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 message
A warning message and chime will
be provided when rapidly approach-
ing a slower moving, braking or
stopped vehicle ahead.
Immediately reduce your speed to
prevent a collision.
Information

The Forward Collision Warning
System is a supplemental sys-
tem to assist you and its
effects may differ according to
road and driving conditions.
Do not solely rely on the sys-
tem and always pay attention
to prevent dangerous situa-
tions from occurring.
FCW is a warning system and
does not apply the brakes
automatically in a near crash
situation. FCWS may not pro-
vide a warning with enough
time to help avoid a crash.
FCWS does not detect pedes-
trians, animals, signs, con-
struction or other objects. It is
the responsibility of the driver
to pay attention to the roadway
to prevent collisions.

you to drive at speeds above 20 mph
(30 km/h) without depressing the
accelerator pedal.
Information
• During normal cruise control opera-tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
