When you turn right/left,
pedestrian is detected in the
forward direction and esti-
mated 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 sys-
tem. 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 vari-
ous 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 pos-
sibility 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.

WARNING
■
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 func-
tion, 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-colli-
sion 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 deter-
mines 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 follow-
ing 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 deter-
mine 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.

Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on
(4.2-inch
display) or
(7-inch display) (
P. 109, 126) of the multi-informa-
tion display.
The system is automatically enabled each time the power switch is
turned to ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■
Changing the pre-collision warning timing
The pre-collision warning timing can be changed on
(4.2-inch
display) or
(7-inch display) (
P. 109, 126) of the multi-informa-
tion display.
The warning timing setting is retained when the power switch is turned
off. However, if the pre-collision system is disabled and re-enabled, the
operation timing will return to the default setting (middle).
If the pre-collision warning timing is changed, emergency steering
assist timing will also be changed accordingly.
If late is selected, emergency steering assist would not operate in
case of an emergency.

While driving on a road with clear white (yellow) lane lines, the LTA
system warns the driver if the vehicle may deviate from the current
lane or course
*
, and also can slightly operate the steering wheel to
help avoid deviation from the lane or course
*
. Also, while the dynamic
radar cruise control with full-speed range is operating, this system will
operate the steering wheel to maintain the vehicle’s lane position.
The LTA 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.

Summary of functions
WARNING
■
Before using LTA system
●
Do not rely solely upon the LTA system. The LTA 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.
