4-5. Using the driving support systems
■
The pre-collision system is operational when
The pre-collision system is on (P. 225) and the following conditions are met:
●
Pre-collision warning:
• Vehicle speed is greater than approximately 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 7 mph (10 km/h).
●
Pre-collision brake assist:
• The VSC is not turned off.
• Vehicle speed is greater than approximately 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 19 mph (30 km/h).
• The brake pedal is depressed.
●
Pre-collision braking:
• The VSC is not turned off.
• Vehicle speed is greater than approximately 10 mph (15 km/h).
• The speed at which your vehicle is approaching the obstacle or the vehi-
cle running ahead of you is greater than approximately 7 mph (10 km/h).

Conditions that may trigger the system even if there is no possibility of a
collision
If the following obstructs the front of the sensor, the system judges that a col-
lision may be possible and operates.
●
When passing by a vehicle while making left or right turns or passing a vehi-
cle in an opposite lane.
●
When the vehicle rapidly approaches an object in front of it (such as another
vehicle, toll gate, etc.)
●
When climbing a steep hill, etc., and there are structures in the upper region
of the road (billboards, low ceilings, street lamps, etc.)
●
When driving through narrow passages or places with low ceilings (bridges,
tunnels, overhead passes, etc.)
●
When driving on an uneven road surface
●
When metal objects are on the road surface causing level differences or
protrusions in the road
●
When an extreme change in vehicle height occurs
●
When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact.
●
When there is an obstacle on the side of an entrance of a curb for road
(guardrails, etc.)
When the system is activated in the situations described above, there is also
a possibility that the brakes will be applied with a force greater than normal.
