WARNING
If you are driving and reach through the

WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired.
There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
You should therefore make sure your vehicle is
operating safely at all times. Otherwise, you
could cause an accident by driving an unsafe
vehicle. If your vehicle is not operating safely,
stop immediately, paying attention to the road
and traffic conditions.
Rev counter
If you exceed the maximum permissible
!
engine speed, the warning tone sounds.
Instrument cluster
You should not drive and change gear by the
sound of the engine, but according to the
engine speed shown in the rev counter.
Avoid driving in the red overrevving range.
This could lead to engine damage.
Example: instrument cluster
Economical speed range (green)
:
Engine brake operating range (yellow)
;
Overrevving range, danger of engine dam-
=
age (red)
If the W indicator lamp in the instrument
cluster lights up, the engine speed is high, e.g.
if you select a low gear when shifting down.
Observe further information in the event win-
dow of the on-board computer.
X
Decelerate using the service brake.
or
X
Shift up a gear.
The W indicator lamp in the instrument
cluster goes out.
General notes on the rev counter:
Observe the rev counter while driving and
R
stay within economical speed range :.
In some situations, it may make sense to
operate the engine outside economical
engine speed range :, e.g. on uphill gradi-
ents or when overtaking.
If you drive the vehicle within economical
R
engine speed range :, you achieve low fuel
consumption and reduced wear.
In engine braking mode, use yellow engine
R
speed range ;. The highest engine braking
effect will be achieved just before red over-
revving range =.
When driving downhill, make sure that the
R
engine speed does not rise into red overrev-
ving range =.
