Q Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may operate even
though there is no possibility of a collision.
O When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots).
O When there is a rut or hole in the surface of the road.
O When driving on a metal cover (grating), such as those used for drainage
ditches.
O When driving up or down a steep slope.
O If a sensor is hit by a large amount of water, such as when driving on a
flooded road.
O There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
O A sensor is coated with a sheet of spray or heavy rain.
O When driving in inclement weather such as fog, snow or a sandstorm.
O When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of ot her vehicles or other devices which
produce ultrasonic waves are near the vehicle.

O If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning.
O When tire chains, a compact spare tire or an emergency tire puncture repair
kit are used.
Q If “Clean Parking Assist Sensor” is displayed on the multi-information
display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.
Q If “Parking Assist Malfunction Visit Your Dealer” is displayed on the
multi-information display
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
Q If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.
Q Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 647)
O On an extremely bumpy road, on an
incline, on gravel, or on grass.

WARNING
QCautions regarding the use of the system
There is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.
Q To ensure the system can operate properly
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
O Do not damage the sensors, and always keep them clean.
O Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.
O Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repai rer, or any reliable repairer. If the
front or rear bumper needs to be removed/installed or replaced, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
O Do not modify, disassemble or paint the sensors.
O Do not attach a license plate cover.
O Keep your tires properly inflated.
Q When to disable the function
In the following situations, disable the function as it may operate even
though there is no possibility of a collision.
O Failing to observe the warnings above.
O A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
Q Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
O When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction.
O When using steam to clean the vehicle, do not direct steam too close to
the sensors as doing so may cause a sensor to malfunction.

Four-wheel drive system
H2 (high speed position, two-
wheel drive)
Use this for normal driving on dry
hard-surfaced roads. This position
gives greater economy, quietest
ride and least wear.
H4 (high speed position, four-
wheel drive)
Use this for driving only on tracks
that permit the tires slide, like off-
road, icy or snow-covered roads.
This position provides greater trac-
tion than two-wheel drive.
The four-wheel drive indicator
light comes on
L4 (low speed position, four-
wheel drive)
Use this for maximum power and traction. Use L4 for climbing or descend-
ing steep hills, off-road driving, and hard pulling in sand, mud or deep
snow.
The four-wheel drive and low speed four-wheel drive indicator lights
come on
The A.D.D. can be engaged or disengaged by the shifting operations
described in the following shifting procedures.
: If equipped
Use the front-wheel drive control switch to select the following
