■Lane departure alert function
When the system determines that
the vehicle might depart from its
lane or course*, a warning is dis -
played on the multi-information dis -
play, and either a warning buzzer
will sound or the steering wheel will
vibrate to alert the driver.
When the warning buzzer sounds or
the steering wheel vibrates, check the
area around your vehicle and carefully

When the vehicle speed exceeds
the speed notific ation threshold
of the speed limit sign displayed,
the sign display will be empha -
sized and a buzzer will sound.
When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys -
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)
If it is detected that your vehicle
is overtaking when a no overtak -

information display, the dis -
played sign will flash and a steer -
ing wheel will vibrate.
Depending on the situation, traffic
environment (traffic direction,

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er 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 war ns 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 sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume 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 t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he 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.
1 Press 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
cruise control.
If the cruise control main switch is

■Setting the vehicle speed
If the “-SET” switch i s pressed while the
vehicle is stopped or being driven at 30 km/h (20 mph) or less, the set speed will

■Exceeding the set speed
In the following situat ions, the vehicle speed exceeds the set speed, and multi-
information display will be highlighted:
●When fully depressing the accelerator

■Vehicles that can be detected
by the Blind Spot Monitor
The BSM function uses radar sen-
sors to detect the following vehicles
traveling in adjacent lanes and
advises the driver of the presence
of such vehicles via the indicators
WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are
installed inside the left and right sides of the rear bumper respectively.
Observe the following to ensure the
Blind Spot Monitor can function cor - rectly.
●Keep the sensor s and the sur-
rounding areas on the rear bumper clean at all times.
If a sensor or its surrounding area
on the rear bumper is dirty or cov - ered with snow, the Blind Spot
Monitor may not operate and a
warning message ( →P.394) will be displayed. In this s ituation, clear off
the dirt or snow a nd drive the vehi-
cle with the operation conditions of the BSM function ( →P.410) satis-
fied for approximately 10 minutes. If
the warning message does not dis - appear, have the v ehicle inspected
by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
●Do not subject a sensor or its sur - rounding area on the rear bumper
to a strong impact.
If a sensor is moved even slightly off position, the system may mal-
function and vehicles may not be
detected correctly. In the following situations, have
your vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor
is scratched or dented, or part of them has become disconnected.
●Do not disassemble the sensor.
●Do not attach acce ssories, stickers
(including transparent stickers), alu - minum tape, etc. to a sensor or its
surrounding area on the rear
bumper.
●Do not modify the sensor or sur -
rounding area on the rear bumper.
●If a sensor or the rear bumper
needs to be removed/installed or replaced, contact any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●Do not paint the rear bumper any
color other than an official Toyota color.

■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Rem ove the ice, snow, dirt, etc., from the sensor to return the
system to normal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not
be able to detect an object. Once the ice melts, the system will return to normal.
If a warning message is displayed even
if the sensor is cle an, there may be a sensor malfunction. Have the vehicle
inspected by any a uthorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
●The area directly under the bum -
pers is not detected.
Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been
detected once.
■When to disable the function
In the following situations, disable the
function as it may operate even though there is no possibility of a colli -
sion.
●The vehicle is equipped with a com - mercial fender pole, wireless
antenna or fog lights.
●The front or rear bumper or a sen -
sor receives a strong impact.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
●When using an automatic car wash
■When using the Toyota parking
assist-sensor
In the following situations, the system
may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●The Toyota parki ng assist-sensor
operation display flashes or shows continuously, a nd a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed continuously and a buzzer does not
sound, except when the mute func -
tion has been turned on.
■Notes when washing the vehicle
Do not apply intensiv e bursts of water or steam to the sensor area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do not spray the sensors directly, as doing
so may cause a sensor to malfunc -
tion.
●When using steam to clean the
vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.
