*: If equipped
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or 7-inch/8-inch display
navigation system (when speed
limit information is available) to pro-
vide information to the driver via the
display.
If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer.
WARNING
■To avoid operating the speed lim- iter by mistake
Switch the speed limiter off using the
speed limiter main switch when not in use.
■Situations unsuitable for speed limiter
Do not use speed limiter in any of the
following situations. Doing so may result in loss of control and could cause an accident resulting
in death or serious injury.
●On slippery roads, such as those
covered with rain, ice or snow
●On steep hills
●When your vehicle is towing a trailer or during emergency towing

WARNING
■Before using the RSA
Do not rely solely upon the RSA sys- tem. RSA is a system which supports
the driver by providing information, but it is not a replacement for a driver’s own vision and awareness.
Drive safely by always paying careful attention to the traffic rules.

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on the
inner side of the rear bumper
on the left and right side to
assist the driver in confirming
safety when changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for safe driving. Always drive safely, tak-
ing care to observe your surround- ings.
The Blind Spot Monitor is a supple-
mentary function which alerts the driver that a vehicle is in a blind spot of the outside rear view mirrors or is
approaching rapidly from behind into a blind spot. Do not overly rely on the
Blind Spot Monitor. As the function cannot judge if it is safe to change lanes, over reliance could lead to an
accident resulting in death or serious injury.
As the system may not function cor-
rectly under certain conditions, the driver’s own visual confirmation of safety is necessary.

Driving
When the Toyota parking assist-
sensor function is disabled, the
Toyota parking assist-sensor OFF
indicator ( P.92) illuminates.
To re-enable the system when it
was disabled, select on the
multi-information display, select
and then on. If disabled using this
method, the system will not be re-
enabled by turning the power
switch off and then to ON.
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function
WARNING
■Cautions regarding the use of
the system
There is a limit to the degree of recog- nition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The driver is always responsible for paying
attention to the vehicle’s surroundings and driving safely.
■To ensure the system can oper-ate properly
Observe the following precautions.
Failing to do so may result in the vehi- cle being unable to be driven safely and possibly cause an accident.
●Do not damage the sensors, and always keep them clean.
●Do not attach a sticker or install an electronic component, such as a
backlit license plate (especially fluo- rescent type), fog lights, fender pole or wireless antenna near a radar
sensor.
●Do not subject the surrounding area of the sensor to a strong impact. If subjected to an impact, have the
vehicle inspected by your any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. If the front or rear bumper needs to be removed/installed or replaced, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Do n ot m od i fy, d is a sse mb l e o r p ai n t the sensors.
●Do not attach a license plate cover.
●Keep your tires properly inflated.
■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.
●Failing to observe the warnings above.
●A non-genuine Toyota suspension (lowered suspension, etc.) is
installed.
■Notes when washing the vehicle
Do not apply intensive 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.

●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 water drops, ice, snow, dirt, etc. Remove the
water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-mal.
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 clean, there may be a sensor malfunction. Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are lim-
ited to the areas around the vehicle’ front and rear bumpers.
●The following situations may occur during use.• Depending on the shape of the object
and other factors, the detection dis- tance may shorten, or detection may be impossible.
• Detection may be impossible if static objects draw too close to the sensor.• There will be a short delay between
static object detection and display (warning buzzer sounds). Even at low speeds, there is a possibility that the
object will come within 30 cm (1.0 ft.)
before the display is shown and the
warning buzzer sounds. • It might be difficult to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.• It may be difficult to hear the sound of
this system due to the buzzers of other systems.
■Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-jecting outwards in the direction of
your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur-
rounding environment may affect the ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.
●There is dirt, snow, water drops or ice
on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor
is frozen the sensor display may be displayed abnormally, or objects, such as a wall, may not be detected.
●When a sensor or the area around a sensor is extremely hot or cold.

●If the vehicle cannot be driven in a
stable manner, such as when the vehicle has been in an accident or is malfunctioning
●When a tire chains, compact spare tire or an emergency tire puncture repair

■Situations in which the system may operate even if there is no possibil-ity of a collision
In some situations, such as the follow- ing, the system may operate even though there is no possibility of a colli-
sion.
●When driving on a narrow road
●When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad cross- ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), such as those used for drainage ditches
●When driving up or down a steep slope
●If a sensor is hit by a large amount of water, such as when driving on a
flooded road
