Parking brake warning light
Check the Parking Brake
Warning Light by placing the
ignition switch to the ON
position (do not start the
engine).
This light will illuminate when the
parking brake is applied with the ignition
switch in the START or ON position.
Before driving, be sure the parking brake
is released and the Brake Warning Light
is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released whilst the engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not
possible, use extreme caution whilst
operating the vehicle and only continue
to drive the vehicle until you can reach a
safe location.
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
manoeuvres. 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.
[ Tyre 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.

Driving your vehicle
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 ignition
switch 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. We recommend that you contact a
HYUNDAI authorised repairer as soon as
possible.
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, we recommend that
you 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 engine off.
Restart the engine. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
with your ABS system. We recommend
that you contact a HYUNDAI authorised
repairer as soon as possible.

Electronic Stability Control
(ESC)
OBC3N061006AU
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle
during cornering manoeuvres.
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 or too quickly when
cornering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
manoeuvres, 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 suddenly on wet, slippery and
rough roads where traction over the four
tyres can suddenly become uneven.
WARNING
Take the following precautions when
using the Vehicle Stability Management
(VSM):

Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Move the shift lever into the 1st
gear (for Manual transmission vehicle)
or N (Neutral) position (for Automatic
transmission/Dual clutch transmission
vehicle), then apply the parking brake,
and place the ignition switch in the
LOCK/OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.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. 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 a HYUNDAI authorised repairer
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 driving,
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 forward.

as the starting conditions are met.
NOTICE
When the engine automatically starts
by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.

Driving your vehicle
Hazardous driving conditions
When hazardous driving elements are
encountered such as water, snow,
ice, mud and sand, take the following
precautions:
[ Drive cautiously and maintain a longer
braking distance.
[ Avoid abrupt braking or steering.
[ When your vehicle is stuck in snow,
mud, or sand, use the second
gear. Accelerate slowly to avoid
unnecessary wheel spin.
[ Put sand, rock salt, tyre chains or
other non-slip materials under the
wheels to provide additional traction
whilst the vehicle becomes stuck in
ice, snow, or mud.
WARNING
Downshifting with an Automatic
transmission, whilst driving on slippery
surfaces can cause an accident. The
sudden change in tyre speed could
cause the tyres to skid. Be careful when
downshifting on slippery surfaces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left to
clear the area around your front wheels.
Then, shift back and forth between the
1st gear and R (Reverse, for manual
transmission vehicle) or R (Reverse)
and a forward gear (for Automatic
transmission vehicle/Dual clutch
transmission vehicle).
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
whilst shifting, and press lightly on the
accelerator pedal whilst the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tyres can increase very quickly.
If the tyres become damaged, a tyre
blow out or tyre explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damages. Try to avoid spinning
the wheels as much as possible to
prevent overheating of either the tyres
or the engine. DO NOT allow the vehicle
to spin the wheels above 35 mph (56
km/h).
