When the settings cannot be
changed, the ON/OFF setting key
will be grayed out.
Also, the following settings can be

●Sonar Audible Alarm
●Automatic Braking
If the Reverse Automatic Brak-
ing (RAB) system malfunctions,
the above indicator illuminates
on the meter. Contact the near-
est Toyota dealer for details.
The 4 sonar sensors are located
in the rear bumper. To ensure
the proper operation of the
Reverse Automatic Braking
(RAB) system, observe the fol-
lowing precautions.
 Do not affix any stickers or
other items on the sonar sen-
sor or the bumper surface
near the sonar sensors.
 Always keep the sonar sensor and the rear bumper surface
near the sonar sensors clean.
 Do not modify rear bumper.
 Do not paint the bumper near
the sonar sensors.
 Do not apply high pressure
water to the sonar sensors
with a high pressure
car-washing machine.
 Do not apply strong impacts
to the rear bumper near the
sonar sensors. If a sensor
becomes misaligned, a sys-
tem malfunction may occur,
including inability to detect
objects in the reversing direc-
tion. If any strong impact is
applied to the rear bumper,
contact a Toyota dealer to
have the system inspected.
 Do not disassemble the sonar
sensors.
If the sonar sensors require repair or
replacement, or if the area of the
rear bumper near the sonar sensors
requires repair, paintwork or
replacement, contact your Toyota
dealer for assistance.

●Do not wipe the camera with alco-
hol, benzine or paint thinner.
Otherwise, discoloration may
occur. To remove contamination,
wipe the camera with a cloth
moistened with a diluted neutral
detergent. Then wipe it with a soft,
dry cloth.
●When waxing the vehicle, be care-
ful not to apply the wax to the
camera. If it comes in contact with
the camera, moisten a clean cloth
with a diluted neutral detergent to
remove the wax.
●The camera lens has a hard coat-
ing to help prevent scratches.
However, when washing the vehi-
cle or cleaning the camera lens,
be careful not to scratch the cam-
era lens. Do not use a washing
brush directly on the camera lens.
The image quality of the rear view
camera may deteriorate.
●Strong light shined on the camera
lens may develop vertical lines
around the light source. This is not
a malfunction.
●Under the fluorescent light, the
display may flicker. However, this
is not a malfunction.
●The image of the rear view cam-
era may be slightly different from
the actual color of the objects.
●If there is a mal function on the
multimedia system screen, refer to
“MULTIMEDIA OWNER'S MAN-
UAL”.
Rear view camera
A rear view camera is
attached to the trunk lid.
When the ignition switch is
in the ON position and the
shift lever is set to R, the
rear view camera automati-
cally displays the rear view
image behind the vehicle on
the multimedia system
screen.
WARNING
●Since the rear view camera
uses a wide-angle lens, the
image on the monitor is different
from the actual view in terms of
distance.
●Since the range of the image on
the monitor is limited, always
check the rear view and the sur-
rounding area with your eyes
and mirrors, and move back-
ward at a slow speed. Moving
backward only by checking the
rear view image from the cam-
era could cause an accident.
●Do not disassemble or modify
the camera, switch or wiring. If
smoke comes out or you smell a
strange odor, stop using the
rear view camera immediately.
Contact your Toyota dealer for
an inspection. Continued use
may result in accident, fire or
electric shock.
NOTICE
●When washing your vehicle with
a high-pressure washer, do not
allow water to touch the camera
directly. Entry of water in the
camera lens may result in con-
densation, malfunction, fire or
electric shock.

WARNING
■Hill-start assist control pre-
cautions
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake,
hill-start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
●Do not stop the engine while
hill-start assist control is operat-
ing, as hill-start assist control
will stop operating, possibly
leading to an accident.

Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size,
and that are the same size,
same maker, same brand and
tread pattern.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.

The air outlets and air volume
changes according to the
selected air flow mode.
WARNING
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■When the outside rear view
mirror defoggers are operat-
ing
Do not touch the outside rear view
mirror surfaces, as they can
become very hot and burn you.
