Enabling/disabling the pre-collision system

The pre-collision system can be enabled/disabled on 

 (

→P. 99)

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 system) 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-collision warning timing

The pre-collision warning timing can be changed on 

 (

→P. 99) of

the multi-information display.

The operation timing setting is retained when the engine switch is
turned off.

Far

The warning will begin to oper-
ate earlier than with the default
timing.

Middle

This is the default setting.

Near

The warning will begin to oper-

Operational conditions
Availability of the pedestrian detection function depends on the region in
which the vehicle was sold. (For specific countries/areas: 

→

P. 261)

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 180 km/h).

(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

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 approximately 19 and
50 mph [30 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

ahead is approximately 20 mph (30 km/h) or more.

●

Pre-collision braking:

• Vehicle speed is between approximately 7 and 110 mph (10 and 180

km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 7 and 50 mph [10 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian

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 will be opera-
tional)
