WARNINGS
The system may fail or operate with
reduced function during cold and
severe weather conditions. Snow,
ice, rain, spray and fog can adversely affect
the system. Keep the front camera and
radar free of snow and ice. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
In situations where the vehicle
camera has limited detection
capability, this may reduce system
performance. These situations include but
are not limited to direct or low sunlight,
vehicles at night without tail lights,
unconventional vehicle types, pedestrians
with complex backgrounds, running
pedestrians, partly obscured pedestrians,
or pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
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 Pre-Collision Assist
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 provides three levels of
functionality:

Driving Aids
1. Alert
2. Brake Support
3. Active Braking
E156131
Alert: When activated, a flashing visual
warning and an audible warning tone
occurs.
Brake Support: Assists the driver in
reducing collision speed by preparing the
brake system for rapid braking. Brake
support does not automatically activate
the brakes, but if the driver presses the
brake pedal even lightly, brake support can
add additional braking up to full force.
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.
Note: The system turns off when you select
4-Wheel Drive Low mode or when you
manually disable AdvanceTrac™.
