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 car 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 prob-
lem with your ABS system. We
recommend that you contact a
HYUNDAI authorised repairer 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)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering manoeu-
vres.
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 a HYUNDAI
authorised repairer as soon as
possible.

Driving your vehicle
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 electric vehicle
control 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 POWER button is in the
ON position, the ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds. After
both lights go off, the ESC is
enabled.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
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.
cle may not respond to the acceler-
ator as it does under routine condi-
tions.
when the ESC activates, the Cruise
Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow. See "Cruise Control System"
later in this chapter. (if equipped)
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 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 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 a banked road such as agradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric power steering)
warning light ( ) is on or blinks.
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 substi-
tute for safe driving practices.
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.

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. 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 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.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
to the P (Park) position, then
apply the parking brake, and
place the POWER 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.

Prerequisite for activation
The FCA gets ready to be activated,
when the FCA is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- Vehicle speed is over 6 mph (10 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a pedestrian or a vehicle in front, which may collide
with your vehicle. (The FCA may
not be activated or may sound a
warning alarm in accordance with
the driving situation or vehicle con-
dition.)
FCA warning message and
system control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels. The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
Collision Warning (1stwarning)
- Yellow
This initial warning message appears
on the LCD display with a warning
chime.
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate
/deactivate the FCA system.
(Continued)
WARNING
(Continued)
The FCA automatically acti-
vates when the POWER but-
ton is in the ON position. The
driver can deactivate the FCA
by canceling the system set-
ting on the LCD display.
If you cancel the ESC
(Electronic Stability Control)
when the FCA system is
turned on the FCA automati-
cally deactivates and the FCA
warning light illuminates.
When the ESC is cancelled
the FCA cannot be activated
on the LCD display.

Collision Warning (2ndwarning)
- Red
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle.
- Your vehicle speed may deceler-ate moderately.
- The FCA system limitedly con- trols the brakes to preemptively
mitigate impact in a collision.
Emergency braking (3rdwarning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs to help deceler-
ate the vehicle.
- The FCA system limitedly con-trols the brakes to preemptively
mitigate impact in a collision. The
brake control is maximised just
before a collision.
Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat- ically cancelled, when risk factors
disappear.
OAEE058244EOAE058030E
The driver should always use
extreme caution whilst operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
