Anti-lock Brake System (ABS)
WARNING
An Anti-Lock Braking System (ABS) or
an Electronic Stability Control (ESC)
system will not prevent accidents
due to improper or dangerous driving
maneuvers. Even though vehicle
control is improved during emergency
braking, always maintain a safe
distance between you and objects
ahead of you. Vehicle speeds should
always be reduced during extreme
road conditions. The braking distance
for vehicles equipped with ABS or ESC
may be longer than for those without
these systems in the following road
conditions.
Drive your vehicle at reduced speeds
during the following conditions:

[Rough, gravel or snow-covered
roads.

[ On roads where the road surface is
pitted or has different surface height.

[ Tire chains are installed on your
vehicle.
The safety features of an ABS or ESC
equipped vehicle should not be tested
by high speed driving or cornering. This
could endanger the safety of yourself or
others.
ABS is an electronic braking system that
helps prevent a braking skid. ABS allows
the driver to steer and brake at the same
time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your brake
pressure and do not try to pump your
brakes. Depress your brake pedal as hard
as possible.
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 ABS is active.
ABS does not reduce the time or distance
it takes to stop the vehicle.
Always maintain a safe distance from the
vehicle in front of you.
ABS will not prevent a skid that results
from sudden changes in direction, such
as trying to take a corner too fast or
making a sudden lane change. Always
drive at a safe speed for the road and
weather conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering wheel
movement can still cause your vehicle to
veer into oncoming traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping distance
than for vehicles equipped with a
conventional brake system.
The ABS warning light (
) will stay
on for several seconds after the Engine
Start/Stop button is in the ON position.
During that time, the ABS will go through
self-diagnosis and the light will go off if
everything is normal. If the light stays on,
you may have a problem with your ABS.
Contact an authorized HYUNDAI dealer
as soon as possible.

Driving Your Vehicle6-28
WARNING
If the ABS warning light () is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your HYUNDAI
dealer as soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, the ABS will
be active continuously and the ABS
warning light (
) may illuminate. Pull
your vehicle over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
with your ABS system. Contact an
authorized HYUNDAI dealer as soon as
possible.
Information
When you jump start your vehicle because
of a drained battery, the ABS warning
light (
) may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning. Have the battery
recharged before driving the vehicle.
Electronic Stability Control (ESC)
ONX4060011
Electronic Stability Control system helps
to stabilize the vehicle during cornering
maneuvers.
ESC checks where you are steering and
where the vehicle is actually going. ESC
applies braking pressure to any one of
the vehicle's brakes and intervenes in the
engine management system to assist the
driver with keeping the vehicle on the
intended path. It is not a substitute for
safe driving practices. Always adjust your
speed and driving to the road conditions.
WARNING
Never drive too fast for the road
conditions 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.

When operating
When the ESC is in operation,
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 ESC activates, the engine may
not respond to the accelerator as it
does under routine conditions.

[ If Cruise Control was in use when
the ESC activates, Cruise Control
automatically disengages. Cruise
Control can be reengaged when the

Vehicle Stability Management
(VSM)
Vehicle Stability Management is a
function of the Electronic Stability
Control (ESC) system. It helps the vehicle
stay stable when accelerating or braking
suddenly on wet, slippery and rough
roads where traction over the four tires
can suddenly become uneven.
WARNING
Take the following precautions when
using Vehicle Stability Management :

[ALWAYS check the speed and the
distance to the vehicle ahead. VSM
is not a substitute for safe driving
practices.

[ Never drive too fast for the road
conditions. VSM system will not
prevent accidents. Excessive speed
in bad weather, on slippery and
uneven roads can result in severe
accidents.

different sizes may cause the VSM
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)
Hill-Start Assist Control 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 (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation) and
releases the brake after 2 seconds or
when the accelerator pedal is depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off
an incline. Hill-Start Assist Control
activates only for approximately 2
seconds (maximum of 5 seconds
when the accelerator pedal is slightly
depressed during HAC operation).
Information

[ Hill-Start Assist Control does not
operate when the gear is shifted to P
(Park) or N (Neutral).

[ Hill-Start Assist Control activates even
when the ESC (Electronic Stability
Control) is off. However, it does not
activate, when ESC does not operate
normally.

Trailer Stability Assist (TSA)
Trailer stability assist is operated as a
vehicle stability control system. The
Trailer stability assist system stabilizes
the vehicle and trailer when the trailer
sways or oscillates. There are various
reasons making vehicle sway and
oscillate. In most cases it happens at
high speed however, if the trailer is
affected by crosswinds, buffeting, and
improper overloading, it may also be at
risk for sway.
Factors of swaying such as: - High speed
- Strong crosswinds
- Improper overloading

- Sudden controlling of steering wheel
- Uneven road
Trailer stability assist system
continuously analyzes the vehicle
and trailer instability. When the
Trailer stability assist system detects
some sway, the brakes are applied
automatically to help stabilize the vehicle
on the front wheel. However, if it is
not enough to stabilize, the brakes are
applied on all wheels automatically and
engine power is properly reduced. When
the vehicle is stable from swaying, trailer
stability assist system does not operate.
Downhill Brake Control (DBC)
ONX4060012
Downhill Brake Control assists the driver
to descend down a steep hill without
having to depress the brake pedal.
The system automatically applies the
brakes to maintain vehicle speed below
a certain speed and allows the driver
to concentrate on steering the vehicle
down hill.
The system is turned off whenever the
engine is turned off.
Press the button to turn on the system
and press the button again to turn it off.
