2015 Hyundai Sonata warning light

5-36
Driving your vehicle
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing 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 ABS may result in a
longer stopping distance than for
vehicles equipped with a convention-
al 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 nor-
mal. If the light stays on, you may
have a problem with your ABS. We
recommend that you contact an
authorised HYUNDAI dealer as soon
as possible.When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously 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 prob-
lem with your ABS system. We
recommend that you contact an
authorised 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.
i
NOTICE
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, we recommend
that you contact your HYUNDAI
dealer as soon as possible.

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilise the
vehicle during cornering manoeu-
vres.
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 man-
agement 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.
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 3 seconds and goes off then
the ESC is turned on.
OLF054448R
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.

ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud, by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.To prevent damage to the
transaxle:
• Do not allow wheel(s) of one
axle to spin excessively whilst
the ESC, ABS, and brake warn-
ing lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively whilst
these lights are displayed.
• When operating the vehicle on a
dynamometer, ensure the ESC is
turned off (ESC OFF light illumi-
nated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
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.
i
NOTICE
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.

mately 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.

to malfunction. When replacing
tyres, make sure they are the
same size as your original tyres
for this vehicle.
NOTICE
i
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)
The Hill-Start Assist Control (HAC)
prevents the vehicle from rolling rear-
wards when starting a vehicle from a
stop on a hill. The system operates
the brakes automatically for approxi-
mately 2 seconds and releases the
brake when the accelerator pedal is
depressed or after 2 seconds.
Information
• 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 activate when the
ESC has malfunctioned.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind your vehicle
by blinking the stop light when the
vehicle is braked rapidly and severe-
ly.
The system is activated when:
• The vehicle suddenly stops (vehi-
cle speed is over 55km/h and the
vehicle deceleration is greater than
7 m/s
2)
• The ABS is activating
When vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the
stop light will stop blinking and the
hazard warning flasher will turn on
automatically.
The hazard warning flasher will turn
off when vehicle speed is over
10km/h after the vehicle has
stopped. Also, it will turn off when the
vehicle is driven at low speed for
some time. You can turn it off manu-
ally by pushing the hazard warning
flasher switch.
i
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher is already on.
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.i
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 with the parking brake
not fully engaged are at risk of
moving inadvertently and caus-
ing injury to yourself or others.
