Notes on the instrument cluster
& WARNING Risk of distraction from infor‐
mation systems and communications
equipment
If you operate information and communica‐
tion equipment integrated in the vehicle when
driving, you will be distracted from the traffic
situation. This could also cause you to lose
control of the vehicle.
Only operate this equipment when the
#
traffic situation permits.
If you cannot be sure of this, stop the
#
vehicle whilst paying attention to road
and traffic conditions and operate the
equipment with the vehicle stationary.
& WARNING Risk of accident due to an
instrument cluster malfunction
If the instrument cluster has failed or mal‐
functioned, you may not recognise function
restrictions applying to safety relevant sys‐
tems.
The operating safety of your vehicle may be
impaired.
Park the vehicle safely as soon as possi‐
#
ble and notify a qualified specialist
workshop.
Observe the legal requirements for the country
you are currently in while operating the instru‐
ment cluster.
Multimedia cockpit rev counter
* NOTE Engine damage due to maximum
engine speed being exceeded
If you exceed the maximum permissible
engine speed, a warning tone will sound.
Avoid driving in the red engine speed
#
range (danger zone).
Instrument cluster (example)
1
Economical operating range (green)
2
Operating range of engine brake
3
Danger zone, danger of overrev (red)
If the W indicator lamp on the instrument clus‐
ter lights up, the engine speed is high, e.g. when
you shift down to a lower gear.
Observe further information in the event window
of the on-board computer.
Reduce the vehicle speed with the service brake
or shift to a higher gear.
The W indicator lamp on the instrument clus‐
ter will go out.
General driving instructions for the rev counter:
Keep an eye on the rev counter while driving
R
and stay within the economical operating
range 1.
In some situations, it may make sense to
operate the engine outside the economical
operating range, e.g. on uphill gradients or
when overtaking.
If you drive the vehicle within the economical
R
operating range 1, you will achieve low fuel
consumption and reduced wear.
In engine braking mode, drive in the engine
R
speed range 2. The maximum engine brak‐
ing effect will be achieved just before the red
danger zone 3.
When driving downhill, make sure that the
R
engine speed does not enter the red danger
zone 3.
Idle speed will be set automatically depending
R
on the coolant temperature.
When the vehicle is stationary, the engine is
R
running and the transmission is in neutral, the
engine will accelerate only slowly.
