Press the Stop & Start cancel
switch to disable the Stop & Start
system.
The Stop & Start cancel indicator
will come on.
Pressing the switch again will
enable the Stop & Start system and
the Stop & Start cancel indicator
will turn off.
■Automatic reactivation of the Stop & Start system
Even if the Stop & Start system is disabled by the Stop & Start can-
cel switch, it will be automatically re-enabled once the engine
switch is turned to the “LOCK” position (vehicles without smart
entry & start system) or off (vehicles with smart entry & start sys-
tem), and then the engine is started.
■If the Stop & Start cancel switch is pressed while the vehicle is
stopped
● When the engine is stopped by the Stop & Start system, pressing
the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
● With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
If the engine is stopped by the Stop & Start system when the vehicle is
on an incline, brake force is temporarily maintained to prevent rolling
backwards until the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
● This function operates on flat surfaces as well as steep incline.
● Sound may be generated by the brakes, but this is not a malfunc-
tion.
● The brake pedal response may change and vibration may occur,
but these are not malfunctions.

WARNING
■TRC/A-TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/A-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 the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, the hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill-start assist control to hold the vehicle on an incline, as doing so
may lead to an accident.
■ When the TRC/VSC/Trailer Sway Control is activated
The slip indicator flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator flashes.
■ When the TRC/A-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 driving
force, do not turn the TRC/A-TRC/VSC/Trailer Sway Control 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 pressure level.
The ABS, TRC, A-TRC, VSC, Trailer Sway Control, hill-start assist control
and downhill assist control 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 suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

WARNING
■When using downhill assist control system
● Do not rely overmuch on the downhill assist control system. This function
does not extend the vehicle’s performance limitations. Always thoroughly
check the road conditions, and drive safely.
● Vehicles with manual transmission: Drive in a low gear. Driving in a high
gear when using downhill assist control system may cause the engine to
stall, which may lose the brake effectiveness and lock the tires, resulting in
an accident.
● Vehicles with manual transmission: On a steep slope, use the engine brak-
ing efficiently. If the vehicle is driven in N or with the clutch pedal
depressed on a steep slope, the load on the brake increases and con-
trolling the vehicle speed may be impossible, resulting in an accident.
■ The system may not operate on the following surfaces, which may lead
to an accident causing death or serious injury
● Slippery surfaces such as wet or muddy roads
● Icy surface
● Unpaved roads
