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.

■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. For this reason, the system may give a warning even if the tire pressure does not reach a low
enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( P.281)
■Replacing tires and wheels
If the ID code of the tire pressure warn- ing valve and transmitter is not regis-
tered, the tire pressure warning system
will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunc-
tion.
Installing tire pressure warn-
ing valves and transmitters
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure warning valves and transmitters, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as the tire pressure warning valves
and transmitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire
pressure warning valves, corrode the valve, and cause sticking and air leaks.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■To avoid damage to the tire pres-sure warning valves and trans-mitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate
properly. If a liquid sealant is used, contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when
replacing the tire. ( P.279)
