■Cautions regarding the use of
the system
The recognition and control capa-
bilities for this system are limited.
The driver should always drive
safety by always being responsi-
ble without over relying on the
system and have a understanding
of the surrounding situations.
●As with a normal vehicle, take
care to observe your surround-
ings while the vehicle is moving.
●Always pay attention to the
vehicle’s surroundings while the
system is operating and
depress the brake pedal as nec-
essary to slow or stop the vehi-
cle.
●When parking, make sure that
the vehicle can be parked in the
target parking space before
beginning operation.
●Depending on the condition of
the road surface or the vehicle,
the distance between the vehi-
cle and a parking space, etc., it
may not be possible to detect a
parking space or the system
may not be able to provide
assistance to the point the vehi-
cle is fully parked.
●This system will guide the vehi-
cle to appropriate positions for
changing the direction of travel,
however, if you feel that the
vehicle is approaching too close
to an adjacent parked vehicle at
any time, depress the brake
pedal and change the shift posi-
tion. However, if this is per-
formed, the number of times the
vehicle changes direction may
increase, and the vehicle may
be parked at an angle.

WARNING
■When the TRAC/ABS/VSC is
activated
The slip indicator light flashes.
Always drive care fully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC systems
are turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC and VSC sys-
tems will not function correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for
further information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driv ing assist sys-
tems, and may cause a system to
malfunction.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.
