itive parking assist detects an object
and provides a warning, the Parking
Support Brake function (static
objects) may not start operating.
■Objects that the Parking Sup-
port Brake function (static
objects) may not detect
The sensors may not be able to
detect certain objects, such as the
following:
●Pedestrian
●Cotton cloth, snow, and other
materials that are poor reflectors
of ultrasonic waves
●Objects which are not perpendicu-
lar to the ground, are not perpen-
dicular to the traveling direction of
the vehicle, are uneven or are
waving
●Low objects
●Thin objects such as wires,
fences, ropes and signposts
●Objects that are e xtremely close
to the bumper

road conditions. As these are
the systems to help ensure
vehicle stability and driving
force, do not turn the
TRAC/VSC/Trailer Sway Con-
trol systems off unless neces-
sary.
●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 pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation p ressure level.
The ABS, TRAC, Trailer Sway
Control and VSC systems will not
function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
