Immediately apply the brake to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking. See the following warning
note.
The intermittent warning sound ceases and
the distance warning lamp
l
goes out
when the necessary distance to the vehicle
ahead is again established.
G
Warning!
An intermittent warning sounds and the
distance warning lamp
l
in the
instrument cluster is illuminated if the
DISTRONIC Plus system calculates that the
distance to the vehicle ahead and your
vehicle’s current speed indicate that the
DISTRONIC Plus will not be capable of
slowing the vehicle sufficiently to maintain
the preset following distance, which
creates a danger of a collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your
own braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact
being avoided.
Tailgating increases the risk of an accident.
G
Warning!
The DISTRONIC Plus brakes your vehicle
with a maximum deceleration of 13 ft/s
2
(4 m/s
2
). This corresponds to
approximately 40% of the maximum
deceleration of your vehicle.
You must also apply the brakes yourself to
avoid a collision. The DISTRONIC Plus
brakes the vehicle in an effort to restore the
preset distance or to maintain the set
speed. The brake pedal is automatically
applied as this happens which results in the
brake pedal moving
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects stored in this area may impair
pedal movement which could interfere with
the braking ability of the DISTRONIC Plus
system.
Do not place your foot under the brake
pedal – your foot could become caught.
G
Warning!
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC Plus has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC
Plus is operating, it is ultimately always the
drivers responsibility to apply the brakes in
order to control the vehicle and avoid a
collision.
