OIn 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 mes-
sage will disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when
driving in the dark, snow, or fog, or when bright lights are shining into the front
camera
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the
surrounding environment can not be properly recognized. In that case, “Pre-Colli-
sion System Unavailable” is displayed.
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle 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 system 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 of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.
to clear the obstruction.
When “Pre-Collision System Unavail-
able” is displayed.Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

Notification function

3365-5. Using the driving support systems
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped
by system control). After the vehicle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will resume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.
1Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator
will come on and a message will be dis-
played on the multi-information display.
Press the switch again to deactivate the

can operate
QBrake operation
A brake operation sound may be heard
and the brake pedal response may
change, but these are not malfunctions.
QWarning messages and buzzers for
dynamic radar cruise control with
full-speed range
Warning messages and buzzers are
used to indicate a system malfunction or
to inform the driver of the need for cau-
tion while driving. If a warning message
is shown on the multi-information dis-
play, read the message and follow the
instructions. (P.309, 518)
QWhen the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake
pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning (P.339) may not be
activated.
