4-5. Using the driving support systems
WARNING
■
TRC/A-TRC 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 system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■
Hill-start assist control
●
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 VSC/Trailer Sway Control 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/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 dealer or repairer, or another duly qualified
and equipped professional 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 the system to malfunction.
