Mercedes-Benz E-Cab 2012 Owners Manual - Manual (Page 170)

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
DISTRONIC PLUS brakes your vehicle with a
maximum deceleration of 13 ft/s
2 (4 m/s 2 ).
This is equivalent to approximately 40 % of
your vehicle's maximum possible
deceleration.
You need to brake yourself to prevent a
collision. DISTRONIC PLUS brakes the vehicle
to restore the set distance from the vehicle
ahead or the set speed.
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.
