■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.
■Active Cornering Assist does not operate effectively when
●Do not overly rely on Active Corner-
ing Assist. Active Cornering Assist may not operate effectively when accelerating down slopes or driving
on slippery road surfaces.
●When Active Cornering Assist fre- quently operates, Active Cornering Assist may temporarily stop operat-
ing to ensure proper operation of the brakes, TRC and VSC.
■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 inclines and roads covered with ice.
●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 is acti-vated
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.
■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.

WARNING
■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
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.
