In the following situations, disable the system, as it may not operate prop-
erly, possibly leading to an accident resulting in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system on and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tester , or when using an on vehicle wheel
balancer
● When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
● 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 tires of a size other than specified are installed

WARNING
■Before using LTA system
● Do not rely solely upon the LTA system. The LTA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.
● Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
● When not using the LTA system, use the LTA switch to turn the system off.
■ Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Failure
to do so may lead to an accident, resulting in death or serious injury.
● Vehicle is driven on a road surface which is slippery due to rainy weather,
fallen snow, freezing, etc.
● Vehicle is driven on a snow-covered road.
● White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
● Vehicle is driven in a temporary lane or restricted lane due to construction
work.
● Vehicle is driven in a construction zone.
● A spare tire, tire chains, etc. are equipped.
● When the tires have been excessively worn, or when the tire inflation pres-
sure is low.
● During emergency towing.
■ Preventing LTA system malfunctions and operations performed by
mistake
● Do not modify the headlights or place stickers, etc. on the surface of the
lights.
● Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● Do not install or place anything on the hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar, etc.).
● If your windshield needs repairs, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.

WARNING
■Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause 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 steep 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
● During emergency towing
● When an approach warning buzzer is heard often

4585-5. Using the driving support systems
Prius Plug-in Hybrid_OM_OM47F38E_(EE)
●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 detection 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.), bicycle 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 tire chains, a compact spare tire or an emergency tire puncture repair
kit are used.

cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road

● When tire chains, compact spare tire or an emergency tire puncture repair
kit are used
■ To ensure the system can operate properly
 P. 4 6 0
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing
 P. 4 6 9
■ Notes when washing the vehicle
 P. 4 6 1
