Instruments and Indicator/Warning Lights
Engine revolutions counter
The start of the red zone in the revolutions counter
indicates the maximum permissible engine speed for all gears for an
engine which has been run in and operating at a normal temperature. You
should shift into the next higher gear before this red zone is reached, or
move the selector lever into position D if your car is fitted with an automatic
gearbox.
One should shift to the next lower gear at the latest when the engine is no
longer running smoothly.
Avoid high engine speeds during the running-in period ⇒ page 176
Caution
The needle of the revolutions counter must on no account move into the
red zone of the scale: Risk of damage to the engine!
For the sake of the environment
Shifting up early helps you save fuel and reduce the operating noise of
your vehicle.

Cold range
If the pointer is still in the left-hand area of the scale it means that the
engine has not yet reached its operating temperature. Avoid running at
high engine speeds, at full throttle and at severe engine loads.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the mid-range of the scale. The pointer may also move further
to the right at high engine loads and high outside temperatures. This is not
critical provided the warning symbol
flash.
If the symbol
in the instrument cluster flashes it means that either the
coolant temperature is too high or the coolant level is too low. Please
refer to the guidelines ⇒ page 31, "Coolant temperature/coolant level ".
WARNING
Pay attention to the warning notes ⇒ page 203, "Working in the
engine compartment" before opening the bonnet and inspecting
the coolant level.
Caution
Additional headlights and other attached components in front of the fresh
air inlet impair the cooling efficiency of the coolant. There is then a risk of
the engine overheating at high outside temperatures and high engine
loads!
