• A sticker, paint, or a chemical is applied to the sonar sensors or the
rear bumper near the sonar sensor.
• The rear bumper is modified. • The rear bumper has been removed
and attached.
• The ground clearance is changed due to the vehicle’s loading condition or
modification.
• There is damage to the sonar sensors or the rear bumper near the sonar
sensor.
• The rear bumper is exposed to strong impact, or the rear bumper is
deformed.
●On a steep hill, the system’s auto-
matic braking ability will be reduced.
●The system is designed to avoid colli-
sions by automatic hard braking when
the vehicle’s reversing speed is less than approximately 5 km/h (3 mph).
However, the system does not guar-
antee that the vehicle will be able to avoid collisions in any situation.
●If the vehicle is reversed at an extremely slow speed, the driver’s
operation may be prioritized. In this
case, automatic braking will not oper- ate.
●The system may not be able to detect and apply the brake with the following
objects.
• Sharp or thin objects such as poles, fences and ropes which may not
reflect the sound wave emitted from
the sonar sensor. • Objects that are too close to the rear
bumper when the shift lever is set to
R. • Objects with a surface which may not
reflect the sound wave emitted from
the sonar sensor such as a chain link
fence.
●Objects the system is not designed to
detect and apply brake. • Pedestrians.
• Moving objects including moving vehi-
cles. • Objects which absorbs sound waves
such as cloth or snow.

angle. • Objects that are low to the ground
such as parking blocks.
• Objects that are high above the ground such as objects hanging from
above.
• Objects that are out of range of the center of the vehicle in the horizontal
direction.
• Objects that are not in a vertical direc- tion.
• Objects which are not perpendicular
to the ground. • Objects which are not directly in the
traveling direction of the vehicle.
• Objects which are uneven or wavy.

• Sound of an air brake.
• Vehicle detection equipment or a sonar from another vehicle.
• A sound wave with a frequency similar
to the vehicle’s system is transmitted near by.
• A vehicle equipped with the same sys-
tem is reversing toward your reversing direction.
●Weather conditions:• Extremely high or extremely low tem-
peratures in which the area near the
sonar sensor becomes too hot or too cold to operate.
• The sonar sensors or the rear bumper
near the sonar sensors are exposed to heavy rain or a significant amount
of water.

tions. Therefore there are cases in which only one of these functions will
activate.
■After the vehicle is stopped by
the system
After the brake pedal is depressed,
the RAB OFF indicator will illumi-
nate and the syst em will temporar-
ily stop operating. The RAB OFF
indicator will turn off when the shift
lever is shifted to a position other
than R.
The system will operate again the
next time the shift le ver is shifted to
R.

following situations.
• When 3 seconds pass after the vehi- cle is stopped
• When any door is opened
• When the RAB warning light is illumi- nated
• When the RAB OFF indicator is illumi-
nated
●The Reverse Automatic Braking
(RAB) system may stop operating temporarily in the following cases and
the RAB OFF indicator will illuminate.
• Ice, snow or mud is adhered to the sonar sensors or the rear bumper
near the sonar sensor
• Objects are too close to the rear bumper when the shift lever is set to R
• The system detects sounds of a simi-
lar frequency to the RAB sonar • When the TRC and VSC mode are
turned off
• When in TRACK mode and the Pre-Collision Braking System has
been turned off
The Reverse Automatic Braking
(RAB) system can be temporarily
canceled by any of the following

When the shift lever is set to R, the
rear view camera automatically dis-
plays the rear view image from the
vehicle. When the lever is set to
other positions, the image before
setting to R is displayed.
1 Set the engine switch to ON.
2 Set the shift lever to R.
●The image of the rear view camera is horizontally reversed as is the case
with the vehicle inside mirror or the
outside mirror.
●When “Rear Camera Delay Control” is
on, the rear view image from the rear view camera will be displayed on the
multimedia system screen for a cer-
tain amount of time after the shift lever
is shifted from R to another position. When any of the following conditions
are met, the rear view image will be
canceled: • The shift lever is sh ifted to P (vehicles
with an automatic transmission)
• The vehicle speed becomes approxi- mately 8 km/h (5 mph) or more
• The parking brake is engaged
• 9 seconds have elapsed since the shift lever was shifted from R to
another position
To turn the function on and off, refer to “Multimedia owner’s manual”.
●It may be difficult to see the image of the rear view camera in the following
cases. This is not a malfunction of the
camera. • The vehicle is in a dark place (at night,
in a tunnel, etc.).
• The vehicle is in an extremely hot or cold place.
• An object (such as raindrops, snow,
dirt, etc.) that disturbs the view of the rear view camera sticks to the lens of
the camera.
• Strong light is shining directly on the camera lens (occasionally, there are
vertical lines on the screen).
The area from the rear end of the
bumper can be viewed. Areas at
both ends of the bumper and areas
just under the bumper cannot be
viewed.
Also, the image from the rear view
camera looks shorter than the
actual distance.
NOTICE
●If mud or snow sticks to or is frozen
on the camera, you must be very
careful when removing it. Otherwise, damage to the camera
may cause a fire or electric shock.
Pour water or lukewarm water over the camera to remove mud and ice,
and wipe it with a soft, dry cloth.
●Do not put a flame close to the camera or wiring. Otherwise, dam-
age or fire may occur.
●When replacing the fuse, be sure to
use a fuse with the specified rating.
Use of a fuse with a different rating may result in a malfunction.
●If you use the rear view camera for a long time while the engine is not
operated, the battery may become
completely discharged.
