MessageDetails/Actions
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
inclines and roads covered with ice.

Driving
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.

delayed for a short period of time immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce odors that occur when starting
the vehicle.

WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger switch during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
■When the outside rear view mir-ror defoggers are operating
Do not touch the outside rear view
mirror surfaces, as they can become very hot and burn you.
