CAUTION
Seat adjustment
Do not recline the seat more than necessary when the vehicle is in motion to
reduce the risk of sliding under the lap belt.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury in the event of an acci-
dent.

IS F_EE
When passing an oncoming vehicle on a right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle's line of travel.
When an overhead billboard or other metallic structure appears to be in
the vehicle’s direct line of travel due to driving on a hill.
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When driving on a bridge.
When the system is activated in the situations described above there is also a
possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 425,
431)
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
