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 AEB 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 braking control is automatical- ly canceled, when risk factors dis-
appear.
The driver should always exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.
✽ ✽ NOTICE
The AEB operates in accordance
with the risk levels, such as the dis-
tance from the vehicle/passer-by in
front, the speed of the vehicle/pass-
er-by in front, and the driver's vehi-
cle operation.
✽ ✽NOTICE
The AEB system logic operates with-
in certain parameters, such as the
distance from the vehicle or pedes-
trian ahead, the speed of the vehicle
ahead, and the driver's vehicle
speed. Certain conditions such as
inclement weather and road condi-
tions may affect the operation of the
AEB system.WARNING
The AEB cannot avoid all colli-
sions. The AEB might not com-
pletely stop the vehicle before
collision, due to ambient weath-
er and road conditions. The
driver has the responsibility to
drive safely and control the
vehicle.
WARNING
The AEB braking control is a
supplemental system and can-
not completely stop the vehicle
nor avoid all collisions. It is the
responsibility of the driver to
safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system as
such conduct increases the risk
of an accident.

Driving your vehicle
✽ ✽NOTICE
• In certain instances and under cer-
tain driving conditions, the AEB
system may activate prematurely.
This initial warning message
appears on the LCD display with a
warning chime.
Also, in certain instances the front
radar sensor or camera recogni-
tion system may not detect the
vehicle or pedestrian ahead. The
AEB system may not activate and
the warning message will not be
displayed.
✽ ✽ NOTICE
• If there is a malfunction with the
AEB system, the automatic emer-
gency braking is not applied even
though it is operating normally.
• The AEB system may not activate if the driver applies the brake
pedal to avoid a collision.WARNING
The AEB is only a supplemental
system for the driver's conven-
ience. It is the driver's responsi-
bility of the driver to control the
vehicle. Do not solely depend
on the AEB system. Rather,
maintain a safe braking dis-
tance, and, if necessary,
depress the brake pedal to
reduce the driving speed.
WARNING
Always maintain a safe dis- tance between your vehicle
and the vehicle in front of you.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Always keep loose objects secured. The AEB system
may activate during braking
and the vehicle may stop sud-
denly causing those loose
objects to become dangerous
projectiles within the vehicle
and increase the risk of
injuries to vehicle occupants.
The AEB system cannot detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.) In these cases,
you must maintain a safe
braking distance, and if nec-
essary, depress the brake
pedal to reduce the driving
speed in order to maintain a
safe distance to avoid an acci-
dent.

The brake control may be insuffi-
cient, possibly causing a collision,
if a vehicle in front abruptly stops.
Always pay close attention and
exercise extreme caution.
Occupants may get injured, if the vehicle abruptly stops by the acti-
vated AEB system. Always pay
close attention and exercise
extreme caution.
The AEB system operates only to detect vehicles or pedestrians in
front of the vehicle.
The AEB system does not operate when the vehicle is in reverse.
The AEB system is not designed to detect other objects on the road
such as animals.
The AEB system does not detect vehicles in the opposite lane.
The AEB system does not detect cross traffic vehicles that are
approaching.Limitations of the System
The Automatic Emergency Braking
(AEB) system is designed to monitor
the vehicle ahead or a pedestrian on
the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the AEB sys-
tem may not operate. The driver must
pay careful attention in the following
situations where the AEB operation
may be limited.
Recognizing vehicles
The sensor may be limited when:
The radar sensor or camera isblocked 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
There is interference by electro- magnetic waves
There is severe irregular reflection from the radar sensor
The radar/camera sensor recogni- tion is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The camera cannot fit the full out- line of a vehicle in front
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)

- Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
The AEB (Autonomous Emergency
Braking) performance decreases
while driving on a curve not recog-
nizing the vehicle in front in the same
lane. It may unnecessarily produce
the warning alarm or brake, or it may
not produce the warning alarm or
brake at all. Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
The AEB system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may the
brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
Check the traffic conditions around
the vehicle before operating the AEB
(Autonomous Emergency Braking).

Driving your vehicle
- Driving on a slope
The AEB performance decreases
while driving upward or downward on
a slope, not recognizing the vehicle
in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal.- Changing lanes
When a vehicle changes lanes in
front of you, the AEB system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.

- Recognizing the vehicle
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, addi-
tional special attention is required.
The AEB system may not be able to
recognize the cargo extending from
the vehicle. In these instances, you
must maintain a safe braking dis-
tance from the rearmost object, and
if necessary, depress the brake
pedal to reduce your driving speed in
order to maintain distance.
Recognizing pedestrians
The sensor may be limited when:
The pedestrian is not fully detected
by the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion 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)
There is an item similar to a per- son's body structure
The pedestrian is small
The pedestrian has impaired mobility
The sensor recognition is limited It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
Sensor recognition changes rapid- ly when driving over a bump
When the vehicle vibrates heavily
Window tint on the front wind- shield, film, water repellent coat-
ing, damaged glass, camera lens
contaminated with foreign objects
(e.g. a sticker, insect, etc.)
When the radar or camera/camera lens is damaged
When the headlights are off or weak at night or in a tunnel
Light such as street light, sunlight or oncoming vehicle light reflects
from water on the road
Driving with the sun in front of you (including headlights of a vehicle
coming from the opposite direc-
tion)

1. Cruise indicator
2. Cruise set indicator
The cruise control system allows you
to program the vehicle to maintain a
constant speed without pressing the
accelerator pedal.
This system is designed to function
above approximately 30 km/h (20
mph ). If the cruise control is left on
(CRUISE indicator light in the
instrument cluster illuminated), the
cruise control can be switched on
accidentally. Keep the cruise con-
trol system off (CRUISE indicator
light OFF) when the cruise control
is not in use, to avoid inadvertently
setting a speed.
Use the cruise control system only when traveling on open highways
in good weather.
Do not use the cruise control driv- ing in heavy or varying traffic, or on
slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.
✽ ✽ NOTICE
• During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
The delay is normal.
• To activate cruise control, depress the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
"This is to check if the brake
switch, which is an important part
to canceling cruise control, is in
normal condition.

To cancel cruise control, do
one of the following:
Press the brake pedal.
Depress the clutch pedal ifequipped with a manual transaxle.
Shift into N (Neutral) with an auto- matic transaxle.
Push the CANCEL switch located on the steering wheel.
Decrease the vehicle speed lower than the memory speed by approx-
imately 20 km/h (12 mph).
Decrease the vehicle speed to less than approximately 25 km/h (15
mph).
Each of these actions will cancelcruise control operation (the SETindicator light in the instrument clus-ter will go off), but it will not turn thesystem off. If you wish to resumecruise control operation, push theRES + switch located on your steer-ing wheel. You will return to your pre-viously preset speed.To resume cruising speed at
more than approximately 30
km/h (20 mph):
If any method other than the
CRUISE button was used to cancel
cruising speed and the system is still
activated, the most recent set speed
will automatically resume when the
RES + switch is pushed.
It will not resume, however, if the
vehicle speed has dropped below
approximately 30 km/h (20 mph).
