Distance warning function
Even if Distronic is deactivated, the distance to the
vehicle ahead continues to be measured, see page 269
for multifunction display.
The Distronic lamp in the speedometer dial illuminates
to advise the driver of a situation which under normal
braking conditions and dry surfaces should have been
addressed by the driver.
The distance notification function can be activated
separately, see page 267. It operates when driving at
speeds above approximately 25 mph
(Canada: 30 km/h).
When recognizing a stationary obstacle or a slower
vehicle moving in the vehicle’s path and the danger of a
collision exists, the distance warning lamp in the
speedometer dial lights up and simultaneously a
continuous warning sounds.
Note:
Model S 55 AMG only:
Distance notification function is deactivated if the
vehicle speed exceeds approximately 160 mph
(260 km/h).
Important!
With the Distronic switched off, only the distance
notification function operates, meaning the vehicle does
not slow down.
Important!
Complex driving situations are not always fully
recognized by Distronic, which could result in wrong or
missing distance warnings.
See page 264 for additional driving hints.
Warning!
If the distance warning lamp in the speedometer
dial lights up while driving and a continuous
warning sounds, immediate attention on the part of
the driver is required.
As required by the traffic situation, apply the
service brakes and navigate around a possible
obstacle. However, do not drive by relying on the
distance notification function as that will result in
an emergency braking application which,
especially depending on road surface conditions
and driver reaction, will not always be able to avoid
a collision.
