■Caution while driving
Do not adjust the steering wheel while driving.
Doing so may cause the driver to mis-
handle the vehicle and cause an acci- dent, resulting in death or serious
injury.
■After adjusting the steering wheel
Make sure that the steering wheel is
securely locked.
Otherwise, the steering wheel may
move suddenly, possibly causing an
accident, and resulting in death or serious injury. Also, the horn may not
sound if the steering wheel is not
securely locked.

Driving
have the system inspected.
• 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.
• Objects whose surface has a diagonal
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.
●When reversing the vehicle, the func-
tions may not be able to work properly or may cause a system malfunction if
the following conditions exist.
High frequency sound from other
sources are nearby:
• Horn sound from another vehicle. • Engine sound from other vehicles.
• 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.
• Fog, snow or sandstorm, etc.
• Air is moving rapidly such as when a strong wind is blowing.
●Parts attached to the rear bumper near the sonar sensor:
• Commercial electronic parts (fog light,
fender pole, radio antenna) or com- mercial attachment parts (trailer hitch,

2384-6. Using other driving systems
bicycle carrier, bumper guard) are
attached. • Parts that emit high frequency sound,
such as a horn or speaker, are
attached.
●Vehicle conditions:
• Ice, snow or mud is adhered to the sonar sensors or the rear bumper
near the sonar sensor.
• The vehicle is significantly inclined. • The ground clearance is significantly
reduced due to the vehicle’s loading
condition, etc. • When the sonar sensor is misaligned
due to a collision or an accident.
●Surrounding environment:
• A cloth banner, flag, hanging branch
or railroad crossing bars are present in the reversing direction.
• When reversing on a gravel or grassy
area. • When reversing in an area where
objects or walls are adjacent to the
vehicle such as narrow tunnels, nar- row bridges, narrow roads or narrow
garages.
• Wheel track or hole is present in the ground of the reversing direction.
• When reversing over a drainage cover
(grating cover).
• The path of the reversing direction is
inclined such as on a steep uphill.
• When reversing downhill.
• Reversing in a garage with a low ceil-
ing or a tunnel.
• A curb or step is present in the revers-
ing direction.
• There is a patch of snow rearward.
• There is a puddle of water.
• There is an obstacle that is next to an
object.
• Going back along a wall.
• The area where the road starts touch-
ing dirt and snow.
• When reversing on an uneven road.
●In circumstances su ch as the follow- ing, it may not be possible to avoid a
collision even when the system oper-
ates normally. • Roads are slippery.
• The tire air pressure is not correct.
• The tires have become worn. • Tire chains are installed.
• Tires which are not the designated
size are installed. • Emergency repairs were performed
using a puncture repair kit.
• The suspension was modified. • Vehicle driving is unstable due to acci-
dent or malfunction.
• The brake system warn ing light is illu-
minated.

( P.142)
 The seat belt reminder light is
flashing
Are the driver and the passenger wear-
ing the seat belts? ( P.339)
