◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
◆Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brake pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to hel p avoid the collision or reduce the
collision speed.
◆Suspension control
When the system determines that the possibility of a frontal colli-
sion is high, the Adaptive Variable Suspension System (
P. 2 9 4 )
will control the damping force of the shock absorbers to help m ain-
tain an appropriat e vehicle posture.

Press the LDA switch again to turn
the LDA system off.
When the LDA system is turned on
or off, operation of the LDA system
continues in the same condition
the next time the engine is started.
WARNING
■Preventing LDA system malfunctions and operations performed by
mistake
● Do not modify the headlights or place stickers, etc., on the su rface of the
lights.
● Do not modify the suspension, etc. If the suspension, etc., needs to be
replaced, contact your Toyota dealer.

Limitations of the sensors
●The detection areas of the sensors are limited to the areas aro und the vehi-
cle’s front corners and the rear bumpers.
● Certain vehicle conditions and surrounding environments, such a s the fol-
lowing, may affect the ability of the sensors to correctly dete ct objects. Pay
particular attention in the following situations. Failure to do so may result in
the vehicle being driven unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a sensor (Cleaning the sens or will
resolve this problem.)
• When the sensor is frozen (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen ma y show an
abnormal display, or objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bumpy road, incline, gravel, or g rass
• When the vicinity of the vehicle is noisy due to vehicle horns , motorcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves
• When there is another vehicle equipped with parking assist sen sor in the
vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless an tenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• A backlit license plate, license plate holder, etc., are insta lled.
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlight or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Toyota suspension (lowered suspension, etc. ) is
installed
In addition to the situations above, there are instances in which, because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

■Automatic leveling function
Regardless of the number of occupants or the luggage load, vehi cle height in
any mode is always adjusted to a fixed height by the automatic leveling func-
tion.
■ When “HI” mode is selected
The vehicle height will change to “N” mode when driving at the speeds of
18 mph (30 km/h).
■ When “LO” mode is selected
●The vehicle height will change to “N” mode when vehicle speed e xceeds
7 mph (12 km/h).
● This mode allows for easy access to the vehicle (getting in and out) and
easy loading and unloading.
■ The electronically modulated air suspension will not operate in the fol-
lowing cases:
● The underbody of the vehicle is touching the surface of the roa d.
● The area around the suspension is covered with ice.
The height control indicators will blink, turn off and then turn on continuously
to indicate that the electronically modulated air suspension is not operational.
To re-enable operation, turn off the engine and then restart it .
■ Even if you hear an operating noise
This does not indicate a problem in the electronically modulate d air suspen-
sion.
■ The electronically modulated air suspension failure warning
The warning message is displayed on the multi-information displ ay, and the
electronically modulated air suspension cannot be activated unt il the malfunc-
tion is corrected.
Stop the engine and start again. If the warning message turns off, the system
operating correctly. If the warning message continues to be displayed, have
your vehicle inspected by your Toyota dealer as soon as possibl e.

WARNING
■The electronically modulated air suspension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, and you may catch part of your body in the vehicle, resulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the veh icle
height in “HI” mode and turn off the electronically modulated a ir suspen-
sion. Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying th e vehicle with
chains/wires for transportation via flat bed truck (Turn the system to the
manual mode and stop the engine.)
● When the vehicle must be towed (Put the vehicle height in “N” mode and
turn the system to the manual mode.)
● When the vehicle gets stuck (Turn the system to the manual mode .)
● When disconnecting a trailer (Put the vehicle height in “N” mod e and turn
the system to the manual mode.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as w ell as dan-
gerous handling characteristics, which may lead to fatal or inj ury accidents.
● Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● “HI” mode should only be used when driving on rough roads, for example
when driving off-road.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.
● Do not select “HI” mode when you load cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the
mode, the vehicle may become unstable when turning abruptly, resulting
in an accident.

WARNING
■When the TRAC/VSC/Trailer Sway Control systems is turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless
necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC, Trailer Sway Control and VSC systems will not function
correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Swa y Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering w heel.
● Begin releasing the accelerator pedal immediately but very grad ually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 193)
