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 vehi-
cle 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

■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a detected object is high.
Each function is operational at the following speed
● Pre-collision warning
● Pre-collision brake assist
● Pre-collision braking
The system may not operate in the following situations:
● If a battery terminal has been disconnected and reconnected and then the
vehicle has not been driven for a certain amount of time
● If the shift lever is in R
● When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)

• 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
● 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
■ If VSC is disabled
● If VSC is disabled (P. 425), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on the multi-information display.
• If the front of the vehicle is raised or
lowered

LDA (Lane Departure Alert with Yaw Assist
Function)
When driving on highways and freeways with white (yellow) lane
lines, this function alerts the driver when the vehicle might depart from
its lane or course* and provides assistance by applying a brake force
to keep the vehicle in its lane or course*.
The LDA system recognizes white
(yellow) lane lines or a course*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass,
soil, or a curb
: If equipped
Summary of functions
WARNING
■ Before using LDA system
● Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such
as from driving for a long period of time.
● Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
● When not using the LDA system, use the LDA switch to turn the system
off.

■Yaw assist function
When the system determines that the vehicle might depart from its
lane or course*, the system provides assistance as necessary by
applying a brake force for a short period of time to keep the vehicle
in its lane.
*: Boundary between asphalt and
the side of the road, such as
grass, soil, or a curb
■Vehicle sway warning function
When the vehicle is swaying
within a lane, the warning
buzzer will sound and a mes-
sage will be displayed on the
multi-information display to alert
the driver.

■ Temporary cancellation of functions
When operation conditions are no longer met, a function may be temporarily
canceled. However, when the operation conditions are met again, operation
of the function is automatically restored. ( P. 358)
■ Yaw assist function
● Depending on the vehicle speed, lane departure situation, road conditions,
etc., the driver may not feel the func tion is operating or the function may not
operate at all.
● The yaw assist of the function is overridden by the driver’s steering wheel
operation.
● Do not attempt to test the operation of the yaw assist function.
● A sound may be heard from the engine compartment when the brake pedal
is depressed, when the yaw assist function is operating. This sound does
not indicate that a malfunction is occurred in the LDA system.
