e pre-collision system
The pre-collision system can be enabled/disabled on ( P. 1 0 5 )
of the multi-information display.
The system is automatically enabled each time the engine switch is
turned to the “ON” position (vehicles without a smart key syste m) or
IGNITION ON mode (vehicles with a smart key system).
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-colli sion warning timing
The pre-collision warning timing can be changed on ( P. 1 0 5 )
of the multi-information display.
The operation timing setting is retained when the engine switch is
turned off.

■Operational conditions
Availability of the pedestrian detection function depends on th e region in
which the vehicle was sold. (For specific countries/areas:
P. 267)
Read the following for details:
Region A
(The pedestrian detection function is available)
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80 km/h).
(For detecting a pedestrian, vehicle speed is between approxima tely 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approxima tely 19 and
50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 20 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 1 80
km/h). (For detecting a pedestrian, vehicle speed is between ap proxi-
mately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or ped estrian
ahead is approximately 7 mph (10 km/h) or more.
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
● If VSC is disabled (only the pre-collision warning function wil l be opera-
tional)

*2: For countries/areas specified as Region B ( P. 267), the pedestrian detec-
tion function may not be available.
■ Cancelation of the pre-collision braking
If either of the following occurs while the pre-collision braki ng function is oper-
ating, it will be canceled:
● The accelerator pedal is depressed strongly.
● The steering wheel is turned sharply or abruptly.
■ 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 determ ine that
there is a possibility of a frontal collision and operate.
• When passing a vehicle or pedestrian
*2
• When changing lanes while overtaking a preceding vehicle
• When overtaking a preceding vehicle that is changing lanes
The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 277)
• When overtaking a preceding vehiclethat is making a left/right turn
• When passing a vehicle in an oncom- ing lane that is stopped to make a
right/left turn
