WARNING
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range i n any of the
following situations.
Doing so may result in inappropriate speed control and could ca use an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclists, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a stee p hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain , etc.)
● When there is rain, snow, etc., on the front surface of the radar or front
camera
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● When your vehicle is towing a trailer or during emergency towing
● When an approach warning buzzer is heard often

■ If the “Check Speed Limiter System.” is displayed on the multi-informa-
tion display
Stop in a safe place, turn the power switch off and back on aga in, and then

malfunctioning. Even though the vehicle can be driven normally, have the
vehicle inspected by any authorized Toyota retailer or Toyota a uthorized
repairer, or any r eliable repairer.
WARNING
■To avoid operating the speed limiter by mistake
Keep the speed limiter switch off when not in use.
■ Situations unsuitable for speed limiter
Do not use the speed limiter in either of the following situati ons.
Doing so may result in control of the vehicle being lost and co uld cause a
serious or fatal accident.
● On slippery roads, such as those covered with rain, ice or snow
● On steep hills
● When towing a trailer or emergency towing
NOTICE
When a warning is issued using the meter display and buzzer after exceed-

■ Conditions under which the system may not function correctly
● The BSM function may not detect vehicles correctly in the following situa-
tions:
• When the sensor is misaligned due to a strong impact to the se nsor or its
surrounding area
• When mud, snow, ice, a sticker, etc., is covering the sensor o r surround-
ing area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching with only a small gap b etween
each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your v ehicle and
the vehicle that enters the detection area
• When the difference in speed between your vehicle and another vehicle
is changing
• When a vehicle enters a detection area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a vehicle remains in the d etection area
• When driving up and down consecutive steep inclines, such as h ills, dips
in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and
the vehicle in an adjacent lane is far away from your vehicle
• When a bicycle carrier or other accessory is installed to the rear of the
vehicle
• When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area
• Immediately after the BSM system is set to on
• When towing a trailer

● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandstorm
● When an object that cannot be detected is between the vehicle and a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collision or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the carried load
● 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
kit is used
● When a sensor or the area around a
sensor is extremely hot or cold.

● If the front of the vehicle is raised or lowered due to the carried load
■ Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnecessary detecting a vehicle and/or object
may increase in the following situations:

WARNING
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an ac cident.
Always drive while checking the safety of the surroundings of t he vehicle.
Depending on the vehicle and road conditions, weather, etc., th e system
may not operate.
The detection capabilities of sensors and radars are limited. A lways drive
while checking the safety of the surroundings of the vehicle.
● The driver is solely responsible for safe driving. Always drive carefully, tak-
ing care to observe your surroundings. The Parking Support Brak e system
is designed to provide support to lessen the severity of collis ions. How-
ever, it may not operate in some situations.
● The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the ve hicle, it is
necessary to depress the brake pedal immediately as brake contr ol will be
canceled after approximately 2 seconds.
● It is extremely dangerous to check the system operations by intentionally
driving the vehicle into the direction of a wall, etc. Never at tempt such
actions.
■ When to disable the Parking Support Brake
In the following situations, disable the Parking Support Brake as the system
may operate even though there is no possibility of a collision.
● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi tional trim strip, etc.), bicycle carrier, or
snow plow
● When using automatic car washing devices
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When a tire chains, compact spare tire or an emergency tire puncture
repair kit is used
