When driving
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
■ Laser radar sensor
■ Warning lights, messages and buzzers for dynamic laser cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving.
(P. 480)
■ Certification
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice and plastic
objects, cannot be detected by the
obstruction sensor.)
Dynamic laser cruise control is canceled
if an obstruction is detected.
This product is a class I laser product complied with 21C.F.R part 1040.10
and 1040.11.

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 480) will not be activated, and a fatal or serious
accident may result.
● The vehicle ahead has higher ground clearance, which means that the
placement of the reflectors is in a higher position.
● The rear section of the vehicle ahead is extremely dirty.
● The vehicle ahead or other vehicles around you are flinging up water or
snow.
● Excessive exhaust gas (black smoke) is coming from the vehicle ahead or
other vehicles around you, obscuring your front view.
● There is an obstruction (protective film, sticker, etc.) on the reflectors on
the vehicle ahead, or reflectors are not installed on the vehicle ahead or
are damaged.
● Heavy luggage in the luggage compartment or rear seats is causing the
nose of your vehicle to tilt up.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane

CAUTION
■Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the laser radar
sensor may not be able to correctly detect vehicles ahead, and a fatal or
serious accident may result.
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly
● When your vehicle is towing a trailer or during emergency towing
■ Handling the laser radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor clean at all times.
Clean the sensor with a soft cloth so you do not mark or damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by a Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, surrounding area.
● Do not modify or paint the sensor.
● If the laser radar sensor needs to be replaced, contact your Toyota dealer.

Intuitive parking assist
: If equipped
The intuitive parking assist is designed to inform you of the approxi-
mate distance between your vehicle and an obstruction by indicator
and buzzer when parking the veh icle. This system uses sensors to
detect obstructions.
This system works when the engine switch is in the ON position and
the shift lever is not in P.
Back and rear corner sensors work only when the shift lever is in
R.
Front corner sensors work when:
● The shift lever is in R
● The shift lever is not in P or R and vehicle speed is approximate
6 mph (10 km/h) or less.

sensors may not be able to detect obstacles that are extremely close
to the vehicle.

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected. Objects lower than the sensors or thin stakes etc. may be detected ini-
tially, but as they draw closer, they may cease to be detected.
• A towing hitch is mounted to the vehicle.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
• When attaching a two-way radio antenna.
• When a towing eyelet is mounted on your vehicle.
• When the bumper is damaged.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by a sensor to be closer
than they are.

226 2-4. Using other driving systems
●The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
• A person near the vehicle (depending on the type of clothes worn)
• When the bumper is damaged.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
■ If the indicator is continuously on
Have the vehicle inspected by your Toyota dealer.
■ If the indicator remains blinking but do not sound the buzzer
Clean the sensors with soft cloth.
CAUTION
■Caution when using the intuitive parking assist
Observe the following precautions.
Failure to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● Do not attach any accessories within the sensor range.
● When moving forward or reversing, always check your surroundings for
safety and drive carefully.
NOTICE
■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.

BSM (Blind Spot Monitor)
: If equipped
The Blind Spot Monitor is a system that assists the driver to confirm
safety when changing lanes.
The system uses radar sensors to de tect vehicles that are traveling
in an adjacent lane in the area th at is not reflected in the outside
rear view mirror (the blind spot), and advises the driver of the vehi-
cles existence via the outside rear view mirror indicator.
BSM main switch
Pressing the switch turns the system on or off. When the switch is set
to on, the switch’s indicator illuminates.
Outside rear view mirror indicator
When a vehicle is detected in the blind spot, the outside rear view mir-
ror indicator on that side illuminates. If the turn signal lever is operated
when a vehicle is in the blind spot, the outside rear view mirror indica-
tor flashes.
