WARNING
■When the TRAC/VSC/Trailer Sway Control are 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 TRAC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems of f 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, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC, VSC and Trailer Sway Control systems will not function
correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Swa y Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failure 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 w heel.
● Begin releasing the accelerator pedal immediately but very grad ually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 191)

P. 371
■ When using the microphone
●It is unnecessary to speak directly into the microphone when gi ving a com-
mand.
● Voice commands may not be recognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while voice commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
● In the following conditions, the system may not recognize the command
properly and using voice commands may not be possible:
• The command is incorrect or unclear. Note that certain words, accents or
speech patterns may be difficult for the system to recognize.
• There is excessive background noise, such as wind noise.
Due to natural language speech recognition technology, this sys tem
enables recognition of a command when spoken naturally. However ,
the system cannot recognize ever y variation of each command.
In some situations, it is possi ble to omit the command for the proce-
dure and directly state the desired operation.
Not all voice commands are displayed in the short cut menu.
This function is available in English, Spanish and French.
