WARNING
■
When to disable the PKSB (Parking Support Brake) system
In the following situations, disable the PKSB (Parking Support Brake) as the system may
operate even though there is no possibility of a collision.
●
When inspecting the vehicle using a chassis roller, chassis dynamo or free roller
●
When loading the vehicle onto a boat, truck or other transport vessel
If the suspension has been modified or tires of a size other than specified are installed
●
●
If the front of the vehicle is raised or lowered due to the carried load
●
When equipment that may obstruct a sensor is installed, such as a towing eyelet,
bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
●
When using automatic car washing devices
If the vehicle cannot be driven in a stable manner, such as when the vehicle 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 a tire chains, compact spare tire or an emergency tire puncture repair kit is
●
used
■
Precautions for the suspension
Do not modify the suspension of the vehicle. If the height or tilt of the vehicle is changed,
the sensors may not be able to detect detectable objects and the system may not operate
correctly, possibly leading to an accident.

System overview
If the PKSB (Parking Support Brake) determines that a collision with a detected
object or pedestrian is possible, the engine output will be restricted to restrain
any increase in the vehicle speed. (Engine output restriction control: See figure 2.)
Additionally, if the accelerator pedal continues to be depressed, the brakes will be
applied automatically to reduce the vehicle speed. (Brake control: See figure 3.)
