Toyota Camry (XV70): PCS (Pre-Collision
System)
The pre-collision system uses a radar sensor and front camera
to detect objects in front of the vehicle. When the system
determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take evasive
action and the potential brake pressure is increased to help
the driver avoid the collision. If the system determines that the
possibility of a frontal collision with an object is extremely high,
the brakes are automatically applied to help avoid the collision
or help reduce the impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed.
Detectable objects
The system can detect the following (The detectable objects differs
depending on the function.):
- Vehicles
- Bicyclists
- Pedestrians
System functions
■ 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 collision
is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.
■ Pre-collision braking
If the system determines that the possibility of a frontal collision is
extremely high, the brakes are automatically applied to help avoid
the collision or reduce the impact of the collision.
■ Emergency steering assist
If the system determines that the possibility of a frontal collision is
high and that there is sufficient space for the vehicle to be steered
into within its lane, and the driver has begun evasive maneuver or
steering, emergency steering assist will assist the steering movements
to help enhance the vehicle stability and for lane departure
prevention.
During operation, the indicator
will illuminate in green.
■ Intersection right/left turn assistance
If the system determines that there is a high possibility of a collision
in the following situations, it will assist with Pre-collision warning
and, if necessary Pre-collision braking.
Depending on the configuration of the intersection, it may not be
possible to support.
- When you turn right/left at an
intersection and cross the
path of an oncoming vehicle
- When you turn right/left,
pedestrian is detected in the
forward direction and estimated
to enter your vehicle's
path (bicyclists are not
detected.)
WARNING
■Limitations of the pre-collision system
- The driver is solely responsible for safe driving. Always drive
safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this
system.
Failure to do so may lead to an accident, resulting in death or serious
injury.
- Although this system is designed to help avoid a collision or help
reduce
the impact of the collision, its effectiveness may change according to
various
conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
- Conditions under which the system may operate even if there is no
possibility
of a collision
- Conditions under which the system may not operate properly
- Do not attempt to test the operation of the pre-collision system
yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.
■Pre-collision braking
- When the pre-collision braking function is operating, a large amount
of
braking force will be applied.
- If the vehicle is stopped by the operation of the pre-collision
braking function,
the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
- The pre-collision braking function may not operate if certain
operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the
pre-collision
braking function from operating.
- In some situations, while the pre-collision braking function is
operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system determines
that the driver is taking evasive action.
- If the brake pedal is being depressed, the system may determine that
the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
■Emergency steering assist
- As emergency steering assist operation will be canceled when the
system
determines that lane departure prevention function has been completed.
- Emergency steering assist may not operate or may be cancel in the
following
cases as the system may determine the driver is taking actions.
- If the accelerator pedal is being depressed strongly, the
steering wheel
is being operated sharply, the brake pedal is being depressed or the
turn signal lever is being operated. In this case, the system may
determine
that the driver is taking evasive action and the emergency steering
assist may not operate.
- In some situations, while the emergency steering assist is
operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly, the steering wheel is operated sharply or the brake
pedal is being depressed and the system determines that the driver is
taking evasive action.
- When the emergency steering assist is operating, if the steering
wheel
is held firmly or is operated in the opposite direction to that which
the
system is generating torque, the function may be canceled.
■When to disable the pre-collision system
In the following situations, disable the system, as it may not operate
properly,
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 engine running 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
vehicle
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 sensor or
front
camera is temporarily installed to the vehicle
