Driving
Dinghy towing
Your vehicle is not designed to be dinghy towed (with 4 wheels
on the ground) behind a motor home.
NOTICE
■To avoid serious damage to your vehicle
Do not tow your vehicle with four wheels on the ground.
■ To prevent causing serious damage to the transmission
Never tow this vehicle from the rear with
the front wheels on the ground.
This may cause serious damage to the
transmission.

WARNING
■When to disable the pre-collision system
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 chass is dyna-
mometer or speedometer tester, or when using an on vehicle whee l bal-
ancer
● When a strong impact is applied to the front bumper or front gr ille, 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
● When tire chains are installed
● When a compact spare tire or an emergency tire puncture repair kit is used
● If equipment (snow plow, etc.) that may obstruct the radar sens or or front
camera is temporarily installed to the vehicle

WARNING
■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 inf lation 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 sur face of the
lights.
● Do not modify the suspension etc. If the suspension etc. needs to be
replaced, contact your Toyota dealer.
● Do not install or place anything on the hood or grille. Also, d o not install a
grille guard (bull bars, kangaroo bar, etc.).
● If your windshield needs repairs, contact your Toyota dealer.

WARNING
■Situations unsuitable for dynamic radar cruise control with ful l-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 s harp 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 rada r 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

■Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding 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 di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on gra ss.
● 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 ult rasonic 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 sandst orm
● When an object that cannot be detected is between the vehicle a nd 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 collis ion 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 car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When a tire chains or compact spare tire is used
●
When a sensor or the area around a
sensor is extremely hot or cold.

Driving
■Conditions under which the system will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles
and/or objects:
● Vehicles approaching from directly behind
● Vehicles backing up in the parking space next to your vehicle
*
●Guardrails, walls, signs, parked vehicles and similar stationar y objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehic le
*
●The distance between the sensor and approaching vehicle gets to o close
*: Depending on the conditions, detection of a vehicle and/or obj ect may
occur.
■ Situations in which the syst em may not operate properly
The RCTA function may not detect vehicles correctly in the foll owing situa-
tions:
● When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
● When mud, snow, ice, a sticker, etc., is covering the sensor or surrounding
area on the position above 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 be tween
each vehicle
● When a vehicle is approaching at high speed
● 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
●
Vehicles that the sensors cannot detect
due to obstructions
Page 332 of 624
3324-5. Using the driving support systems
●When towing a trailer
● When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
are installed
● If the front of the vehicle is raised or lowered due to the car ried load
●
When backing up on a slope with a
sharp change in grade
● When backing out of a sharp angle park-
ing spot
● When turning while backing up
