ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. ( P.344)
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditioning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.,
to clear the obstruction.

*: If equipped
The system can detect the following (The detectable objects differs
depending on the function.):
The countries and areas for each region listed in the table are current as of

PCS (Pre-Collision System)*
The pre-collision system uses a rad ar sensor and front camera to
detect objects ( P.231) 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 act ion
and the potential brake pressure is increased to help the drive r
avoid the collision. If the syste m 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 reduc e the
impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g timing
can be changed. ( P.235)

■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.
“BRAKE!”
■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 (for
region A)
If the system determines that the
possibility of a collision with a
pedestrian 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 move-
ments to help enhance the vehicle
stability and for lane departure pre-
vention. During operation, the indi-
cator will illuminate in green.
■Intersection right/left turn
assistance (for region A)
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 pos-
sible to support.

WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking care to observe your sur-
roundings. Do not use the pre-collision system instead of normal braking opera-
tions under any circumstances. This system will not prevent colli-sions 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 effec-
tiveness may change according to various conditions, therefore the system may not always be able to
achieve the same level of perfor- mance.Read the following conditions care-
fully. Do not overly rely on this sys- tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos-sibility of a collision: P. 2 3 8
• Conditions under which the system may not operate properly: P. 2 3 9
●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 brak-
ing function, the pre-collision brak- ing function operation will be canceled after approximately 2 sec-
onds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain opera-tions 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 tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
234
Owners Manual_Europe_M52N75_en
4-5. Using the driving support systems
WARNING
●In some situations, while the pre- collision braking function is operat-
ing, operation of the function may be canceled if the accelerator pedal is depressed strongly or the steer-
ing wheel is turned and the system determines that the driver is taking evasive action.
●If the brake pedal is being depressed, the system may deter-
mine that the driver is taking eva- sive action and possibly delay the operation timing of the pre-collision
braking function.
■Emergency steering assist (for
region A)
●As emergency steering assist oper- ation will be canceled when the sys-
tem determines that lane departure prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol-
lowing 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 tak-ing evasive action and the emer-
gency steering assist may not operate.
• In some situations, while the emer- gency 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-colli-sion 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 chassis dynamometer or speedometer tes-
ter, 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
