PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and camera sen-

sor to detect vehicles and pedestrians* in front of your vehicle.

When the system determines that the possibility of a frontal col-

lision with a vehicle or pedestrian is high, a warning operates to

urge the driver to take evasive action and the potential brake

pressure is increased to help the driver avoid the collision. If the

system determines that the possibility of a frontal collision with

a vehicle or pedestrian is extremely high, the brakes are auto-

matically applied to help avoid the collision or help reduce the

impact of the collision.

The pre-collision system can be disabled/enabled and the warning

timing can be changed. (P. 278)

*: Depending on the region in which the vehicle was sold, the pedestrian

detection function may not be available. Contact any authorized Toyota

retailer or Toyota authorized repairer, or any reliable repairer for details.

◆ Pre-collision warning

When the system determines

that the possibility of a frontal

collision is high, a buzzer will

sound and a warning message

will be displayed on the multi-

information display to urge the

driver to take evasive action.

◆ Pre-collision brake assist

When the system determines that the possibility of a frontal colli-

sion is high, the system applies greater braking force in relation to

how strongly the brake pedal is depressed.

◆ Pre-collision braking

When the system determines that the possibility of a frontal colli-

sion is high, the system warns the driver. If the system determines

that the possibility of a frontal collision is extremely high, the brakes

are automatically applied to help avoid the collision or reduce the

collision speed.

WARNING

■ When to disable the pre-collision system

In the following situations, disable the system, as it may not operate prop-

erly, possibly leading to an accident resulting in death or serious injury:

●When the vehicle is being towed

●When your vehicle is towing another vehicle

● When transporting the vehicle via truck, boat, train or similar means of

transportation

●When the vehicle is raised on a lift with the hybrid system operating and

the tires are allowed to rotate freely

● When inspecting the vehicle using a drum tester such as a chassis dyna-

mometer or speedometer tester, or when using an on vehicle wheel bal-

ancer

●When a strong impact is applied to the front bumper or front grille, due to

an accident or other reasons

4

● If the vehicle cannot be driven in a stable manner, such as when the vehi-

cle has been in an accident or is malfunctioning

● When the vehicle is driven in a sporty manner or off-road

● When the tires are not properly inflated

● 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 cam-

era sensor is temporarily installed to the vehicle

■ Operational conditions

Availability of the pedestrian detection function depends on the region in

which the vehicle was sold.

Regions

Function availability

Region A

The pedestrian detection function is available

Region B

The pedestrian detection function is not available

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

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].)

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

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

● Pre-collision 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].)

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

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

● Pre-collision 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].)

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

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

■ Pedestrian detection function*

The pre-collision 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. 287)

*: Depending on the region in which the vehicle was sold, the pedestrian

detection function may not be available.

■ Cancelation of the pre-collision braking

●If either of the following occur while the pre-collision braking function is

operating, 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

• 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

C-HR_HV_OM_Europe_OM10538E

283

• 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 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 there is a vehicle, pedestrian or

object by the roadside at the entrance

of a curve

4

• 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 a crossing pedestrian

approaches very close to the vehicle

board, etc.) at the top of an uphill road

• When rapidly closing on an electric toll gate barrier, parking area barrier,

or other barrier that opens and closes

• When using an automatic car wash

• When driving through or under

objects that may contact the vehicle,

such as thick grass, tree branches, or

a banner

• When the vehicle is hit by water, snow, dust, etc. from a vehicle ahead

• When driving through steam or smoke

• When there are patterns or paint on the road or a wall that may be mis-

taken for a vehicle or pedestrian*

• When driving near an object that reflects radio waves, such as a large

truck or guardrail

■ Situations in which the system may not operate properly

● In some situations such as the following, a vehicle may not be detected by

the radar sensor and camera sensor, preventing the system from operating

properly:

• If an oncoming vehicle is approaching your vehicle

• If a vehicle ahead is a motorcycle or bicycle

• When approaching the side or front of a vehicle

• If a preceding vehicle has a small rear end, such as an unloaded truck

• If a preceding vehicle has a low rear

end, such as a low bed trailer

• If a vehicle ahead is carrying a load which protrudes past its rear bumper

4

• If a vehicle ahead has extremely high

ground clearance

• If a vehicle ahead is irregularly shaped, such as a tractor or side car

• If the sun or other light is shining directly on a vehicle ahead

• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle

• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,

acceleration or deceleration)

• When suddenly cutting behind a preceding vehicle

• When a vehicle ahead is not directly

in front of your vehicle
