(vehicles without a smart key system) or the “ENGINE START STOP” switch
is turned to ACCESSORY mode or tur ned off (vehicles with a smart key sys-
tem) while the rear wiper is operating, the rear wiper will stop at that position
and will not return to the retracted position.
■ If no washer fluid sprays
Check that the washer nozzle is not blocked if there is washer fluid in the
washer fluid reservoir.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. drip prevention function) can be changed.
(Customizable features P. 664)
NOTICE
■When the rear window is dry
Do not use the wiper, as it may damage the rear window.

Detection range of the sensors
Approximately 1.6 ft. (50 cm)
Approximately 4.9 ft. (150 cm)
The diagram shows the detection
range of the sensors. Note that
the sensors cannot detect obsta-
cles that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape
of the object etc.

■Sensor detection information
● Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

When the active traction control system is operatingIf all wheels spin, the slip indica-
tor flashes to indicate that the
active traction control system
has been engaged.
CTH24AS047
■When the rear differential is locked (vehicles with a rear differential
lock system)
The active traction control system is activated only when vehicle speed is
less than 4 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. This may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “A-TRAC” indicator will go off and the “TRAC OFF” indicator
will come on. Stop the vehicle in a safe place. (There is no problem with con-
tinuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■The active traction control system m ay not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

AUTO LSD system (2WD models)
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en wheel spinning occurs in a
ditch or rough surface.
■ System operation
Press the VSC off switch to
turn on the system.
At this time, the “AUTO LSD”
and VSC off indicators will
come on.
To turn off the system, press
the switch again.

indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
CTH24AS047
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “AUTO LSD” indicator will flash and the “TRAC OFF” indica-
tor will come on. Stop the vehicle in a safe place. (There is no problem with
continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■ To avoid an accident
● Do not use the AUTO LSD system in conditions other when wheel spin-
ning occurs in a ditch or rough surfaces.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

While the downhill assist control system is operating
The slip indicator will flash to
indicate that the downhill assist
control system is operating, and
the stop lights and high mounted
stoplight will turn on.
CTH24AS047
■Operating tips
The system will operate when the shift lever is in any position other than P.
However, to make effective use of the system it is recommended that the
shift lever be shifted to the “2” or “1” range of S.
■ If the downhill assist control system indicator flashes
● In the following situations, the indicator flashes and the system will not
operate:
• The transfer mode is not in L4 (part-time 4WD models) or L4L (full-time
4WD models).
• The rear differential is locked.
• The brake system overheats. The system will cease operation and a buzzer will sound to alert the
driver. At this time, the “TRAC OFF” indicator will come on. Stop the
vehicle in a safe place. Refrain from using the system until the indicator
stops flashing and stays on. (There is no problem with continuing nor-
mal driving.)
● In the following situations, the indicator flashes to alert the driver, but the
system will still operate:
• The shift lever is in N. (Engine braking will not occur.)
• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operation. The indicator will flash dur-
ing operation, and then go off when the system is fully off.
