Disabling the pre-crash safety system

Press the PCS switch for 3 sec-
onds or more.

The PCS warning light will turn
on and a message will be dis-
played on the multi-information
display.
To enable the system, press the
PCS switch again.

The system is enabled each time the engine switch is turned to the “ON”
position (vehicles without smart entry & start system) or IGNITION ON
mode (vehicles with smart entry & start system).

■

Changing the pre-crash warning timing

Press the PCS switch to display
the current warning timing on
the multi-information display.
Each time the PCS switch is
pressed with the warning timing
displayed, the warning timing
will change as follows.

The operation timing setting is
retained when the engine switch
is turned to the “LOCK” position
(vehicles without smart entry &
start system) or off (vehicles
with smart entry & start system).

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 operate later than with the default timing.

Operational conditions
The pre-crash safety system is enabled and the system determines that the
possibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:

●

Pre-crash warning:
• Vehicle speed is between approximately 10 and 180 km/h (7 and

110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph]. For detecting a stationary vehicle,
vehicle speed is between approximately 10 and 90 km/h [7 and 55 mph].)

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

ahead is approximately 10 km/h (7 mph) or more.

●

Pre-crash brake assist: 
• Vehicle speed is between approximately 30 and 180 km/h (19 and

110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 30 and 80 km/h [19 and 50 mph]. For detecting a stationary vehi-
cle, vehicle speed is between approximately 30 and 90 km/h [19 and
55 mph].)

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

ahead is approximately 30 km/h (19 mph) or more.

●

Pre-crash braking:
• Vehicle speed is between approximately 10 and 180 km/h (7 and

110 mph). (For detecting a pedestrian, vehicle speed is between approxi-
mately 10 and 80 km/h [7 and 50 mph]. For detecting a stationary vehicle,
vehicle speed is between approximately 10 and 90 km/h [7 and 55 mph].)

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

ahead is approximately 10 km/h (7 mph) 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-crash warning function will be operational)

●

If the low speed four-wheel drive indicator light is illuminated (only the
pre-crash warning function will be operational)

●

If the PCS warning light is flashing or illuminated

■

Cancelation of the pre-crash braking
If either of the following occur while the pre-crash braking function is operat-
ing, 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 determine that
there is a possibility of a frontal collision and operate.
• When passing a vehicle or pedestrian
• When changing lanes while overtaking a preceding vehicle
• When overtaking a preceding vehicle that is changing lanes

The pre-crash safety system detects
pedestrians based on the size, profile,
and motion of a detected object. However,
a pedestrian 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. 298)

• When overtaking a preceding vehicle

that is making a left/right turn

• When passing a vehicle in an oncom-

ing lane that is stopped to make a
right/left turn

4-5. Using the driving support systems

• When rapidly closing on a vehicle ahead
• If the front of the vehicle is raised or lowered, such as when the road sur-

face is uneven or undulating

• When approaching objects on the roadside, such as guardrails, utility

poles, trees, or walls

• When driving on a narrow path surrounded by a structure, such as in a

tunnel or on an iron bridge

• When there is a metal object (manhole cover, steel plate, etc.), steps, or a

protrusion on the road surface or roadside

• When driving on a road where relative

location to vehicle ahead in an adja-
cent lane may change, such as on a
winding road

• When there is a vehicle, pedestrian,

or object by the roadside at the
entrance of a curve

• When a crossing pedestrian

approaches very close to the vehicle

• When passing through a place with a

low structure above the road (low ceil-
ing, traffic sign, etc.)
