4-5. Using the driving support systems
■The system can be operated when
●The engine switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●Steering wheel is turned approxi-mately 90° or more (Front side sen-sors, rear side sensors) (if equipped)
●The parking brake is released.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to normal.
■Sensor detection information
The following situations may occur during use.
●The sensors may be able to only detect objects near the front and rear bumpers.
●Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●If an object is extremely close to a sensor, it may not be detected.
●There will be a short delay between object detection and display. Even at low speeds, there is a possibility that
the object will come within the sen- sor’s detection areas before the dis-play is shown and the warning beep
sounds.
●It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
●It may be difficult to hear the buzzer if buzzers for other systems are sound-
ing.
■Objects which the system may not be properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
WARNING
●Do not modify, disassemble or paint the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■When to disable the function
In the following situations, disable the function as it may operate even though there is no possibility of a colli-
sion.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
■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.
●When using a high pressure washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc- tion.
●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.

WARNING
■The ABS does not operate effec- tively when
●The limits of tire gripping perfor-mance have been exceeded (such as excessively worn tires on a snow
covered road).
●The vehicle hydroplanes while driv-
ing at high speed on wet or slick roads.
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from
the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with pot-holes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not
be achievable while driving on slip- pery road surfaces, even if the TRC/VSC system is operating. Drive
the vehicle carefully in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively when
●Do not overly rely on hill-start assist control. Hill-start assist control may not operate effectively on steep

WARNING
●Unlike the parking brake, hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-dent.
■When the TRC/VSC is activated
The slip indicator light flashes. Always
drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-tions. As these are the systems to
help ensure vehicle stability and driv- ing force, do not turn the TRC/VSC systems off unless necessary.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and safely of the surrounding area
can be ensured.
●Proper use of expert mode requires
a professional level of driving skill. When using expert mode, always check the road conditions and sur-
rounding area and drive more care- fully than usual.
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern
and total load capacity. In addition, make sure that the tires are inflated to the recommended tire inflation pres-
sure level. The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle. Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem
or modifying the suspension will affect the driving assist systems, and may cause a system to malfunction.
■Secondary Collision Brake (if equipped)
Do not rely solely upon the Secondary Collision Brake. This system is designed to help reduce the possibil-
ity of further damage due to a second- ary collision, however, that effect changes according to various condi-
tions. Overly relying on the system may result in death or serious injury.
■Active Torque Split AWD system
●The Active Torque Split AWD sys-tem is designed to ensure driving
stability on general roads and not for off-road driving such as for rally-ing. Do not subject the system to
extreme driving conditions.
●Drive carefully on slippery road sur-
faces.

the driving conditions:
zDo not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
zTo ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
zCheck for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
zRemove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
zPark the vehicle and shift the
shift lever to 1 or R without set-
ting the parking brake. The park-
ing brake may freeze up,
preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
Side chain:
3 mm (0.12 in.) in diameter
10 mm (0.39 in.) in width
