WARNINGS
This system is an extra driving aid. It
does not replace your attention and
judgment, or the need to apply the
brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle.
The system cannot help prevent all
crashes. Do not rely on this system
to replace driver judgment and the
need to maintain a safe distance and
speed.
Using the Pre-Collision Assist
System
The Pre-Collision Assist system is active
at speeds above approximately 3 mph
(5 km/h) and pedestrian detection is active
at speeds up to 50 mph (80 km/h).
E156130
If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system is design to provide three levels of
functionality:
1. Alert
2. Brake Support
3. Active Braking

Driving Aids
Alert: When activated, a red warning light
flashes, an audible warning chime sounds
and a warning message shows in the
information display.
Brake Support: The brake support system
assists the driver in reducing the collision
speed by lightly applying the brakes. If the
risk of collision further increases after the
warning light illuminates, the brake support
prepares the brake system for rapid
braking. This may be apparent to the driver.
The system does not automatically
activate the brakes, but if you press the
brake pedal, the system may apply full
force, even if the brake pedal is lightly
pressed.
Active Braking: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.
Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.
