QPre-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.
QPre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.
QPre-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.

• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
O In some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
Q If VSC is disabled
O If VSC is disabled (P. 359), the pre-collision brake assist and pre-collision
braking functions are also disabled.
O The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on the multi-information display.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

To change the set speed, operate the lever until the desired set speed
is obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1.0 km/h (0.6 mph) each time the lever
is operated.
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also canceled
when the brakes are applied or the
clutch pedal (manual transmission
only) is depressed.
Pushing the lever up resumes
the constant speed control.
Resuming is available when the vehicle speed is more than approximately
30 km/h (20 mph).

O The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may show an
abnormal display, or objects may not be detected.
O The sensor is covered in any way.
O On an extremely bumpy road, on an incline, on gravel, or on grass
O When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of ot her vehicles or other devices which
produce ultrasonic waves are near the vehicle.
O A sensor is coated with a sheet of spray or heavy rain.
O If objects draw too close to the sensor.
O When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
O When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the detection range.
O Strong wind is blowing.
O When driving in inclement weather such as fog, snow or a sandstorm.
O When an object that cannot be detected is between the vehicle and a
detected object.
O 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.
O If the orientation of a sensor has been changed due to a collision or other
impact.
O When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow.
O If the front of the vehicle is raised or lowered due to the carried load.
O If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning.
O When tire chains, a compact spare tire or an emergency tire puncture repair
kit are used.
O When a sensor or the area around a
sensor is extremely hot or cold

Q Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may operate even
though there is no possibility of a collision.
O When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots).
O When there is a rut or hole in the surface of the road.
O When driving on a metal cover (grating), such as those used for drainage

WARNING
QTrailer 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 envi ronment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
Q If trailer sway occurs (vehicles with Trailer Sway Control)
Observe the following precautions.
Failing to do so may cause death or serious injury.
O Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway by turning the steering wheel.
O Begin releasing the accelerator pedal immediately but very gradually 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. 215)
