Limitation of the system

The AEB is an assistant system for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
The AEB monitors the driving situa-
tions through the radar and the cam-
era sensor. For any vehicle activity
occurring outside the sensor range,
the AEB may not function. The driver
should exercise caution in the follow-
ing situations, as the AEB operation
may be limited:

Recognizing vehicles

- The radar or the camera is con-

taminated with foreign substances.

- It heavily rains or snows.
- There is electromagnetic interfer-

ence.

- Something in the path of travel

deflects the radar waves.

- The vehicle in front has a narrow

body. (i.e. motorcycles and bicycles)

- The driver’s view is degraded by

driving towards sunlight, reflected
light, or darkness.

- The camera cannot see the full

profile of the vehicle in front.

- The vehicle in front is a special

vehicle, such as a heavily-loaded
truck or a trailer.

- When driving on uneven surfaces

or roads with sudden gradient
changes

- In construction sites, railroads, or

other metalic objects are on the
road

- The vehicle in front does not turn

ON the rear lights, does not have
rear lights, has asymmetric rear
lights, or has rear lights out of angle.

- The outside brightness is greatly

changed, such as entering/exiting
the tunnel.

- The vehicle driving is unstable.
- The radar/camera sensor recogni-

tion is limited.

Driving your vehicle

- Driving on a curve
The AEB performance decreases
while driving on a curve. The AEB
may not recognize the vehicle in front
even in the same lane. It may unnec-
essarily produce the warning mes-
sage and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
While driving on a curve, exercise
caution, and, if necessary, depress
the brake pedal.

While driving on a curve, the AEB
may recognize the vehicle in front in
the next lane. Exercise caution, and, if
necessary, depress the brake pedal.
Or, depress the accelerator pedal to
maintain the driving speed. Always,
take a look around the vehicle for
your safety.

- 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
Even though the vehicle in the next
lane enters into your lane, it may not
be recognized by the AEB, until it
enters the AEB sensing range.
Especially when the vehicle in the
next lane abruptly enters into your
lane, it is more likely not be recog-
nized. Always be attentive to driving
conditions.

When the stopped vehicle in front
gets out of the lane, it may not be
recognized by your AEB. Always be
attentive to driving conditions.

- Recognizing the vehicle
When the vehicle in front has heavy
loading extended rearward, or when
the vehicle in front has higher ground
clearance, it may induce a haz-
ardous situation.

Driving your vehicle

Recognizing pedestrians

- The pedestrian is not fully captured

by the camera sensor, or the
pedestrian does not walk in the
upright position.

- The pedestrian moves very fast.
- The pedestrian abruptly appears in

front.

- The pedestrian wears clothes sim-

ilar in color to the background.

- Conditions outside are too bright or

too dark.

- The vehicle drives at night or in the

darkness.

- There is an item similar in shape a

person’s body structure.

- The pedestrian is small.
- The pedestrian has impaired

mobility.

- The pedestrian blends in with their

surroundings.

- Sensor recognition is limited by

rain, snow, fog, etc.

- There is a group of pedestrians.

✽

✽

NOTICE

The system may temporarily cancel
due to the strong electric waves.

• Pay great caution to the vehicle in

front, when it has heavy loading
extended rearward, or when it has
higher ground clearance.

• The sensor only detects pedestri-

an, not carts, bicycles, motorcy-
cles, luggage bags, or strollers.

WARNING -

Testing the
AEB

The AEB does not operate in
certain situations. Thus, never
test-operate the AEB against a
person or an object. It may
cause a severe injury or even
death.

WARNING -

AEB and
Towing

Cancel the AEB in the User
Settings on the LCD display,
before towing another vehicle.
While towing, the brake applica-
tion may adversely affect your
vehicle safety.

The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 20 mph (30
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control 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 when
driving 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 oper-

ation, when the SET switch is acti-
vated or reactivated after applying
the brakes, the cruise control will
energize after approximately 3 sec-
onds. This delay is normal.

• To activate cruise control, depress

the brake pedal at least once after
turning the engine start/stop but-
ton to the ON position or starting
the engine. This is to check if the
brake switch which is important
part to cancel cruise control is in
normal condition.
