Toyota Camry: Parking Support Brake function - PKSB (Parking Support
If the Parking Support Brake detects that a collision with an object is
possible, the engine output will be restricted to restrain any increase
in the vehicle speed. (Engine output restriction control: See A below.)
Additionally, if the accelerator pedal continues to be depressed, the
brakes will be applied automatically to reduce the vehicle speed.

Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.

- A sensor may be covered with ice, snow, dirt, etc. In this case, remove
ice, snow, dirt, etc., from the sensor to return the system to normal. If
message is shown even after removing dirt from the sensor, or shown when
the sensor was not dirty to begin with, have the vehicle inspected at your

- Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.
■Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the safety of the surroundings of the vehicle.
Depending on the vehicle and road conditions, weather, etc., the system
may not operate.
The detection capabilities of sensors and radars are limited. Always drive
while checking the safety of the surroundings of the vehicle.
- The driver is solely responsible for safe driving. Always drive
care to observe your surroundings. The Parking Support Brake system
is designed to provide support to lessen the severity of collisions.
it may not operate in some situations.
- The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the system has stopped the vehicle, it is
necessary to depress the brake pedal immediately as brake control will be
canceled after approximately 2 seconds.
- It is extremely dangerous to check the system operations by
driving the vehicle into the direction of a wall, etc. Never attempt such
■When to disable the Parking Support Brake
In the following situations, disable the Parking Support Brake as the
may operate even though there is no possibility of a collision.
- When inspecting the vehicle using a chassis roller, chassis dynamo or
- 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
- If the front of the vehicle is raised or lowered due to the carried
- When equipment that may obstruct a sensor is installed, such as a
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier,
- When using automatic car washing devices
- If the vehicle cannot be driven in a stable manner, such as when the
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 or compact spare tire is used
