Hill-Start Assist Control (HAC)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed.
Information
• The HAC does not operate when the
shift lever is in P (Park) or N (Neutral).
• The HAC activates even when the
ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not operate nor-
mally.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while 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 (34 mph).)
• 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 (25 mph),
• 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
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.

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 authorized 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 tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while 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.
WARNING

5-40
Driving your vehicle
The Blind Spot Detection System
(BSD) uses radar sensors in the rear
bumper to monitor and warn the driv-
er of an approaching vehicle in the
driver's blind spot area.
The system monitors the rear area of
the vehicle and provides information
to the driver with an audible alert and
an indicator on the outside rearview
mirrors.(1) BSD (Blind Spot Detection)
The blind spot detection range
varies relative to vehicle speed.
Note that if your vehicle is travel-
ing much faster than the vehicles
around you, the warning will not
occur.
(2) LCA (Lane Change Assist)
The Lane Change Assist feature
will alert you when a vehicle is
approaching in an adjacent lane
at a high rate of speed. If the driv-
er activates the turn signal when
the system detects an oncoming
vehicle, the system sounds an
audible alert.
The time of alert varies according
to the speed difference between
you and the approaching vehicle.
(3) RCTA (Rear Cross Traffic Alert)
The Rear Cross Traffic Alert fea-
ture monitors approaching cross
traffic from the left and right side
of the vehicle when your vehicle is
in reverse. The feature will operate
when the vehicle is moving in
reverse below about 10 km/h (6
mph). If oncoming cross traffic is
detected a warning chime will
sound.The time of alert varies according
to the speed difference between
you and the approaching vehicle.
BLIND SPOT DETECTION SYSTEM (BSD) (IF EQUIPPED)

Closing at high speed
•Always be aware of road con-
ditions while driving and be
alert for unexpected situa-
tions even though the Blind
Spot Detection System is
operating.
•The Blind Spot Detection
System (BSD) is not a substi-
tute for proper and safe driv-
ing. Always drive safely and
use caution when changing
lanes or backing up the vehi-
cle. The Blind Spot Detection
System (BSD) may not detect
every object alongside the
vehicle.

Second stage alert
A warning chime to alert the driver will activate when:
1. A vehicle has been detected in the blind spot area by the radar system
(the warning light will illuminate on the outside rearview mirror (i.e., in

Information
• The warning chime will turn off
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 system may not operate proper-
ly due to other factors or circum-
stances. Always pay attention to
your surroundings.
• If the sensing area near the rear
bumper is blocked by either a wall
or barrier or by a parked vehicle,
the system sensing area may be
reduced.
i(Continued)
•The Blind Spot Detection
System (BSD) and Rear Cross
Traffic Alert (RCTA) are not a
substitute for proper and safe
driving practices. Always
drive safely and use caution
when changing lanes or back-
ing up your vehicle. The Blind
Spot Detection System (BSD)
may not detect every object
alongside the vehicle.
•With the system activated, the
warning light on the outside
rearview mirror will illuminate
whenever a vehicle is detect-
ed at the rear side by the sys-
tem.
To avoid accidents, do not
focus only on the warning
light and neglect to see the
surrounding of the vehicle.
•Drive safely even though the
vehicle is equipped with a
Blind Spot Detection System
(BSD) and Rear Cross Traffic
Alert (RCTA). Do not solely
rely on the system but check
your surrounding before
changing lanes or backing the
vehicle up.
The system may not alert the
driver in some conditions so
always check your surround-
ings while driving.
