●When Active Cornering Assist fre - quently operates, Active Cornering
Assist may temporarily stop operat -
ing to ensure prop er operation of the brakes, TRC and VSC.
■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.
●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/ABS/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 indicat or light flashes.
■When the TRC/VSC/Trailer Sway Control systems are turned off

speed appropriate t o the road condi- tions. As these ar e the systems to
help ensure vehicl e stability and driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys -
tems off unle ss 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, tread pattern
and total load capac ity. In addition,
make sure that the tires are inflated to the recommended tire inflation pres -
sure level.
The ABS, TRC and VSC/Trailer Sway Control systems will not function cor -
rectly if different ti res are installed on
the vehicle. Contact any authorized Toyota
retailer or Toyota a uthorized 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.
■Trailer Sway Control precaution
The Trailer Sway C ontrol system is not able to reduce tr ailer sway in all
situations. Depending on many fac -
tors such as the conditions of the
vehicle, trailer, road surface and driv - ing environment, the Trailer Sway
Control system may not be effective.
Refer to your traile r owner’s manual for information on how to tow your
trailer properly.
