■ The pre-collision system is operational when
The pre-collision system is on (→P. 306) and the following conditions are met:
● Pre-collision warning:
• Vehicle speed is greater than about 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 7 mph (10 km/h).
● Pre-collision brake assist:
• The VSC is not turned off.
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.
● Pre-collision braking:
• The VSC is not turned off.
• Vehicle speed is greater than about 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 7 mph (10 km/h).
● Suspension control (vehicles with Adaptive Variable Suspension system):
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehicle running
ahead of you is greater than about 19 mph (30 km/h).
■ Conditions that may trigger the system even if there is no possibility of a collision
In any of the following situations where the frontal area of the radar sensor is interrupted,
the radar sensor may detect possibility of a frontal collision and the system may be acti-
vated.
● When passing by an oncoming vehicle in a curve or a turn to the right or the left
● When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
etc.)
● When there is a structural object (billboard, low ceiling, fluorescent light, etc.) above
the uphill road ahead
● When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
● When driving on an uneven road surface
● When there is a metal object, bump, or protrusion on the road surface
● When vehicle’s front part is raised or lowered depending on loading conditions
● When the direction of radar sensor is misaligned by strong impact applied on an area
around the radar sensor, etc.
● When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
● When the front of your vehicle is pointing upwards (caused by towing a trailer or put-
ting a heavy load in the luggage compartment, etc.)
When the system is activated in the situations described above, there is also a possibility
that the brakes may be applied with a force greater than normal.
