■Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on (P. 787)
of the multi-information 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.
WARNING
● 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

■Changing the pre-collision warning timing
The pre-collision warning timing can be changed on (P. 787)
of the multi-information display.
The warning timing setting is retained when the power switch is turned
off. However, if the pre-collision system is disabled and re-en abled, the
operation timing will return to the default setting (middle).
For region A: If the pre-collision warning timing is changed, e mer-
gency steering assist timing will also be changed accordingly.
If late is selected, emergency steering assist would not operat e in
case of an emergency.
Early
Middle
This is the default setting.

■Operational conditions for each pre-collision function
The pre-collision system is enabled and the system determines t hat the pos-
sibility of a frontal collision with a detected object is high.
The system may not operate in the following situations:
• If a 12-volt battery terminal has been disconnected and reconn ected and
then the vehicle has not been driven for a certain amount of ti me
• If the shift lever is in R
• When the VSC OFF indicator is illuminated (only the pre-collis ion warning
function will be operational)
The operation speeds and operation cancellation for each functi on is listed
below.

● Pre-collision brake assist

● Pre-collision braking
If either of the following occur while the pre-collision brakin g function is oper-
ating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
● Emergency steering assist (for region A)
When the turn signal lights are flashing, emergency steering as sist will not
operate in case of an emergency.
If any of the following occur while the emergency steering assi st function is
operating, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
• The brake pedal is depressed.

■ Object detection function
The system detects objects based on their size, profile, motion , etc. However,
an object may not be detected depending on the surrounding brig htness and
the motion, posture, and angle of the detected object, preventi ng the system
from operating properly. ( P. 383)
The illustration shows an image of detectable objects.
■ Conditions under which the system may operate even if there is no pos-
sibility of a collision
● In some situations such as the following, the system may determine that
there is a possibility of a frontal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while overtaking a detectable object, etc.
• When rapidly closing on a detectable object, etc.
• When approaching objects on the roadside, such as detectable o bjects,
guardrails, utility pol es, trees, or walls
Region A
Region B
• When approaching a detectable
object in an adjacent lane or on the
roadside, such as when changing the
course of travel or driving on a wind-
ing road

• When there are patterns or paint in front of your vehicle that may be mis-
taken for a detectable object
• When the front of your vehicle is hit by water, snow, dust, et c.

on an iron bridge
• When there is a metal object (manhole cover, steel plate, etc. ), steps, or a
protrusion in front of your vehicle

entrance of a curve

that is changing lanes or making a
right/left turn
• When passing a detectable object in
an oncoming lane that is stopped to
make a right/left turn

radar in the vicinity (tunnels, truss bridges, gravel roads, sn ow covered
road that have tracks, etc.)

a crossing pedestrian has already exited the path of your vehic le
• For region A: While making a right/left turn, closely in front of an oncom-
ing vehicle or a crossing pedestrian
• For region A: While making a right/left turn, when an oncoming vehicle or
