WARNING
■To avoid malfunction of the front sensor
Observe the following precautions.
Otherwise, the front sensor may not operate properly, possibly leading to an
accident resulting in death or serious injury.
● Keep the windshield clean at all times. If the windshield is dirty or covered
with an oily film, water droplets, snow, etc., clear the windshield. If the
inner side of the windshield in front of the front sensor is dirty, contact your
Toyota dealer.
● If there is a large difference in temperature between the inside and outside
of the vehicle, such as in winter, the windshield is likely to fog up easily. If
the part of the windshield in front of the front sensor is fogged up or cov-
ered with condensation or ice, the PCS warning light may illuminates and
the system may be temporarily disabled. In this case, use the windshield
defogger to remove the fog, etc. ( →P. 321)
● If the area of the windshield in front of the front sensor is covered with
water droplets, use the windshield wipers to remove them.
If the water droplets are not sufficiently removed, the performance of the
front sensor may be reduced.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration).
A: From the top of the windshield to
approximately 4.0 in. (10 cm) below
the bottom of the front sensor
B: Approximately 7.9 in. (20 cm) (Approximately 4.0 in. [10 cm] to the
right and left from the center of the
front sensor)
● Do not install or attach anything to the
inner side of the windshield under the
front sensor (shaded area in the illustra-
tion).
A: Approximately 4.0 in. (10 cm) (Start-
ing from the bottom of the front sen-
sor)
B: Approximately 7.9 in. (20 cm) (Approximately 4.0 in. [10 cm] to the
right and left from the center of the
front sensor)
