154Driving and operating
General information
9Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the valid
following distance based on traffic, weather and visibility conditions.
The complete attention of the
driver is always required while
driving. He shall always be ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also on
other objects.
In the following cases, forward
collision alert may not detect a vehicle
ahead or sensor performance is
limited:
■ on winding roads,
■ when weather limits visibility, such as fog, rain, or snow,
■ when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage.
Following distance
indication The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in
the vehicle's path. It is active at
speeds above 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 94 . Press
the MENU button on the turn signal
lever to select Vehicle Information
Menu X and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
