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)

driving on a slippery road, the
engine rpm (revolutions per minute)
may not increase even if you press
the accelerator pedal deeply. This is
to maintain the stability and traction
of the vehicle and does not indicate
a problem.
ESC OFF condition
To cancel ESC operation :

Press the ESC OFF button briefly.
The ESC OFF indicator light and/or
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and/or message "Traction & Stability
Control disabled" illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the ignition switch is placed in the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
vehicle, ESC will automatically turn
on again.

To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle
to spin excessively whilst the
ESC, ABS, and parking brake
warning 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, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) 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 tyres can sud-
denly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control
(ESC) is on.
Vehicle speed is approximately
above 15 km/h on curve roads.
Vehicle speed is approximately
above 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.
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 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.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
rearwards 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.
Information
• HAC does not operate when the shift
lever is in P (Park) or N (Neutral).
• HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when
ESC does not operate normally.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, whilst sharply and
severely braking.
The system is activated when:
The vehicle suddenly stops. (The
deceleration power exceeds 7 m/s
2,
and the driving speed exceeds 55
km/h.)
The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights:
When the driving speed is under
40 km/h,
When the ABS is deactivated, and
When the sudden braking situation
is over.The hazard warning flasher turns
OFF:
When the vehicle drives at a low
speed for a certain period of time.
The driver can manually turn OFF
the hazard warning flasher by
pressing the button.Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flashers are already on.
i
i
Always be ready to depress the
accelerator pedal when starting
off an incline. The HAC activates
only for approximately 2 sec-
onds.
WARNING

5-52
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. 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.
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. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the ignition
switch in the LOCK/OFF posi-
tion.
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.

The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light. Both FCA
warning light and warning mes-
sage will disappear once the ESC
warning light issue is resolved.
FCA is only a supplemental
system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed or to stop the vehicle.
(Continued)(Continued)
In certain instances and
under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclist (if equipped) ahead.
The FCA system may not acti-
vate and the warning mes-
sage may not be displayed.
Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
(Continued)
WARNING
(Continued)
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid collision.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.

Detecting the vehicle in front of you
If the vehicle in front of you has
cargo that extends rearward from
the cab, or when the vehicle in
front of you has higher ground
clearance, additional special atten-
tion is required. The FCA system
may not be able to detect the cargo
extending from the vehicle. In
these instances, you must main-
tain a safe braking distance from
the rearmost object, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain distance.
Detecting pedestrians or
cyclists (if equipped)
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the camera recogni-
tion system, for example, if the
pedestrian is leaning over or is not
fully walking upright
The pedestrian or cyclist is moving
very quickly or appears abruptly in
the camera detection area
The pedestrian or cyclist is wear-
ing clothing that easily blends into
the background, making it difficult
to be detected by the camera
recognition system
The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclists or a large
crowd There is an item similar to a per-
son's body structure
The pedestrian or cyclist is small
The pedestrian has impaired
mobility
The sensor recognition is limited
The radar sensor or camera is
blocked with a foreign object or
debris
Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
The field of view in front is
obstructed by sun glare
The windscreen glass is fogged
up; a clear view of the road is
obstructed
The adverse road conditions cause
excessive vehicle vibrations whilst
driving
The sensor recognition changes
suddenly when passing over a
speed bump

Driving your vehicle
The warning will stop when:
- The detected vehicle moves out of
the sensing area or
- When the vehicle is right behind
your vehicle or
- When the vehicle is not approach-
ing your vehicle or
- When the other vehicle slows
down.
- The vehicle's approaching speed is
decreased.(Continued)
The warning of the Rear
Cross-Traffic Collision
Warning System may not
sound whilst other system's
warning sounds.
When the operation condition
of the Rear Cross-Traffic
Collision Warning System is
satisfied the warning will
occur every time a vehicle
approaches the side/rear of
your stopped (0 km/h vehicle
speed) vehicle.
The system's warning may
not operate properly if the
left/right of your vehicle's rear
bumper is blocked by a vehi-
cle or obstacle.
Always pay attention to road
and traffic conditions whilst
driving, whether or not the
warning light on the outside
rearview mirror illuminates or
there is a warning alarm.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system's warning sounds.
(Continued)
CAUTION
If any other warning sound
such as seat belt warning
chime is already generated,
the Rear Cross-Traffic
Collision Warning system
warning may not sound.
Drive safely even though the
vehicle is equipped with a
Rear Cross-Traffic Collision
Warning System. Do not sole-
ly rely on the system but
check your surrounding when
backing the vehicle up.
The driver is responsible for
accurate brake control.
