You can prevent the intervention of the PRE-
®
SAFE Brake at any time by:
depressing the accelerator pedal further
R
activating kickdown
R
releasing the brake pedal.

The braking action of PRE-SAFE
ended automatically if:
you maneuver to avoid the obstacle.
R
there is no longer any danger of a rear-end
R
collision.
there is no longer an obstacle detected in
R
front of your vehicle.
With the help of the radar sensor system,
®
PRE-SAFE Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds of up to 40 mph (70 km/h), PRE-
®
SAFE Brake can also detect stationary
obstacles, for example, stopped or parked
vehicles.
If you approach an obstacle and PRE-SAFE
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If
you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventive passenger protection
measures (PRE-SAFE
Y
( page 52). If, at speeds over 20 mph
(30 km/h), a risk of collision remains and you
do not brake, take evasive action or
significantly accelerate, automatic braking
may be performed up to the level of
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided.
