The pre-crash safety system is operational when
Pre-crash seat belts (type A)
• Vehicle speed is greater than about 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash seat belts (type B)
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
Pre-crash brake assist:
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.
Pre-crash braking:
• The pre-crash braking off switch is not pressed.
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 15 km/h (10 mph).

Conditions that may trigger the system even if there is no possibility of a
collision
When there is an object by the roadside at the entrance to a curve
When passing an oncoming vehicle on a curve
When driving over a narrow iron bridge
When there is a metal object on the road surface
When driving on an uneven road surface (nose up, nose down)
When passing an oncoming vehicle on a left-turn (left-hand drive vehi-
cles) or right-turn (right-hand drive vehicles)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
When the steep angle of the road causes a metal object located beneath
the road surface to be seen ahead of the vehicle
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When passing through an overpass
When the system is activated in the situations described above, there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.

Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 571,
578)
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of vehicle, such as at an intersection
If a vehicle suddenly cuts in front of vehicle, such as when overtaking
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.

CAUTION
Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, tak-
ing care to observe your surroundings and checking for any obstacles or
other road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is
intended to assist the driver in avoiding collisions through the process of
LOOK-JUDGE-ACT. There are limits to the degree of assistance the system
can provide, so please keep in mind the following important points.
Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in
front of the vehicle, and only within a limited range. It is not a mechanism
that allows careless or inattentive driving, and it is not a system that can
assist the driver in low-visibility conditions. It is still necessary for the
driver to pay close attention to the vehicle’s surroundings.
Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-crash safety system is that from obstacles it has
detected directly in front of the vehicle. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of collision in any given situation.
Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop
safely. For this reason, when encountering a dangerous situation the driver
must take direct and immediate action in order to ensure the safety of all
involved.

CAUTION
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
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
luggage compartment etc.)
Vehicles that cut in suddenly
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function
effectively:
Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover 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 become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
Do not modify or paint the sensor and grille cover.

Cargo and luggage
CAUTION
Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
Receptacles containing gasoline
Aerosol cans
Take notice of the following information about storage precautions,
cargo capacity and load:
Stow cargo and luggage in the luggage compartment when-
ever possible.
Be sure all items are secured in place.
To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
For better fuel economy, do not carry unnecessary weight.

CAUTION
Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
Stow cargo and luggage in the luggage compartment whenever possible.
Do not stack cargo and luggage in the luggage compartment higher than
the seatbacks.
Such items may be thrown about and possibly injure people in the vehicle
in the event of sudden braking or in an accident.
Do not place cargo or luggage in or on the following locations as the item
may get under the brake or accelerator pedal and prevent the pedals from
being depressed properly, block the driver’s vision, or hit the driver or
passengers, causing an accident:
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the luggage cover
• On the instrument panel
• On the dashboard
Secure all items in the occupant compartment, as they may shift and injure
someone in the event of an accident or sudden braking.
When you fold down the rear seats, long items should not be place
directly behind the front seats.
Never allow anyone to ride in the luggage compartment. It is not designed
for passengers. They should ride in their seats with their seat belts prop-
erly fastened. Otherwise, they are much more likely to suffer death or seri-
ous bodily injury, in the event of sudden braking or an accident.

CAUTION
Load and distribution
Do not overload your vehicle.
Do not apply loads unevenly.
Improper loading may cause deterioration of steering or braking control
which may cause death or serious injury.
