WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the safety of the surroundings of the vehi-cle.
Depending on the vehicle and road conditions, weather, etc., the system may not operate.
The detection capabilities of sensors and radars are limited. Always drive while checking the safety of the sur-
roundings of the vehicle.
●The driver is solely responsible for
safe driving. Always drive carefully, taking care to observe your sur-roundings. The Parking Support
Brake system is designed to pro- vide support to lessen the severity of collisions. However, it may not
operate in some situations.
●The Parking Support Brake system
is not designed to stop the vehicle completely. Additionally, even if the system has stopped the vehicle, it
is necessary to depress the brake pedal immediately as brake control will be canceled after approximately
2 seconds.
●It is extremely dangerous to check
the system operations by intention- ally driving the vehicle into the direction of a wall, etc. Never
attempt such actions.
■When to disable the Parking Sup- port Brake
In the following situations, disable the
Parking Support Brake as the system may operate even though there is no possibility of a collision.
●When inspecting the vehicle using a chassis roller, chassis dynamo or
free roller
●When loading the vehicle onto a
boat, truck or other transport vessel
●If the suspension has been modi-
fied or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
●When equipment that may obstruct a sensor is installed, such as a tow-ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in an accident or
is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact spare tire or an emergency tire puncture
repair kit is used
■Precautions for the suspension
Do not modify the suspension of the vehicle. If the height or tilt of the vehi-cle is changed, the sensors may not
be able to detect detectable objects and the system may not operate cor-rectly, possibly leading to an accident.

5-4. Using the driving support systems
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/ABS/VSC/Trailer Sway Control 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/Trailer Sway
Control 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/Trailer Sway Control sys- tems off unless necessary.Trailer Sway Control is part of the
VSC system and will not operate if VSC is turned off or experiences a malfunction.
■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, VSC and Trailer
Sway Control systems will not func- tion 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.
■Trailer Sway Control precaution
The Trailer Sway Control system is
not able to reduce trailer sway in all situations. Depending on many fac-tors such as the conditions of the
vehicle, trailer, road surface and driv- ing environment, the Trailer Sway Control system may not be effective.
Refer to your trailer owner’s manual for information on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead. Do not try to control trailer swaying by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very gradu- ally to reduce speed. Do not increase speed. Do not apply vehi-
cle brakes. If you make no extreme correction with the steering or brakes, your
vehicle and trailer should stabilize. ( P.237)
■Secondary Collision Brake
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.
