WARNING
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.

8 Washer/wiper dual
operation
Pulling the lever o perates the wip-
ers and washer.
The wipers will au tomatically oper-
ate a couple of times after the
washer squirts.
■The windshield wipers and
washer can be operated when
The power swit ch is in ON.
■Effects of vehicle speed on
wiper operation
Vehicles with in termittent wind-
shield wipers
With low speed windshield wiper
operation selected, wiper operation
will be switched from low speed to
intermittent wiper operation when
the vehicle is stationary. (However,
when the wiper intervals are
adjusted to highest level, the mode will not switch.)

intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor sensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops. An optical
sensor is adopt ed. It may not
operate properly when sunlight
from the rising or setting of the
sun intermittently strikes the wind-
shield, or if bugs, etc. are p resent
on the windshield.

other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge

3145-5. Using the driving support systems
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disapp ear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such as
after the vehicle is parked in an
extremely cold environment, use the
air conditioning system to increase
the temperature around the front
camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc. to clear the obstruction.

3225-5. Using the driving support systems
such as heavy rain, fog, snow or a
sandstorm
• When driving through steam or smoke
• When the surrounding area is dim, such as at dawn or dusk, or while
at night or in a t unnel, making a
detectable object appear to be
nearly the same color as its sur-
roundings
• When driving in a place where the surrounding brightness changes
suddenly, such as at the entrance
or exit of a tunnel
• After the hybrid system has started the vehicle has not been
driven for a certain amount of time

• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
●In some situations such as the fol-
lowing, sufficien t braking force
may not be obtained, preventing
the system from performing prop-
erly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, extremely hot, or
wet • If the vehicle is not properly main-
tained (brakes or tires are exces-
sively worn, imprope r tire inflation
pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface

3325-5. Using the driving support systems
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curve, warnings will
occur earlier than during straight-
lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assist of the steer-
ing assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and

played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■Warning message
If the follo wing warning message is
displayed on the multi-information display and the LT
A indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
