FORWARD ALERT FUNCTION
WARNINGS
Never wait for a collision warning.
When driving you are responsible for
maintaining the correct distance and
speed, even when the system is used.
The system will only react to vehicles
in front travelling in the same
direction and will not react to slow
or stationary vehicles.
Never drive in a manner to provoke
the system. The system is designed
to assist in emergencies only.
CAUTIONS
Warnings may be triggered late, be
absent or triggered unnecessarily due
to detection beam issues. See
Principle of Operation (page 166).
The system uses the same radar
sensors as adaptive cruise control and
therefore has the same limitations.
See Principle of Operation (page 166).
Note: The brake support system only
reduces the collision speed if you brake
immediately once alerted.
Note: If the brake pedal is depressed
sufficiently quickly then braking is
implemented with full brake function, even
if the force on the pedal is light.
Note: Brake support prepares the brake
system for rapid braking and the brakes are
applied gently, which may be noticed as a
slight jerk.
Note: The collision alerts will only occur if
the system is switched on, however the
brake support is always on and cannot be
turned off.
Note: The system may be used with or
without the Adaptive cruise control system
being activated.
The system assists you by warning of the
risk of a collision with a vehicle in front.
The system alerts you by warning chimes
and a visual warning in the information
display. See Information Messages
(page 97).
Brake support is activated to enable full
braking effectiveness, and reduce the
severity of a collision with the vehicle in
front.
Switching the system on and off
Note: When the system is switched off, a
warning indicator will remain illuminated in
the information display. See Warning
Lamps and Indicators (page 80).
Note: The system status and settings will
remain unchanged during ignition cycles.
The system can be switched on and off
using the information display. See General
Information (page 84).
Adjusting the warning sensitivity
You may adjust the system warning
sensitivity using the buttons on the steering
wheel. See General Information (page
84). This controls how early the visual and
audible warning is activated.
