Auto Collision Preparation

well as the automatic braking

Collision Alert as well as the
automatic braking capability of the
Auto Collision Preparation feature
are available. The Alert setting
disables most automatic braking
functions of the Auto Collision
Preparation feature. Some
last-second automatic braking
capability is still provided with the
Alert setting, but it is much less
likely to be triggered by most driving
conditions. Off disables all Forward
Collision Alert and automatic
braking capabilities of the Auto
Collision Preparation feature.
Select Off, Alert and Brake, or Alert.
