Tachometer
The orange warning zone between arrows 1
and 2 shows the currently permissible engine
speed, which depends on engine temperature.
As engine temperature increases, some of the
LEDs in this warning zone go out one after
another.
As much as possible, avoid driving at engine
speeds within the illuminated warning zone.
Never force the engine speed up into the red
warning zone beginning at arrow 2. To protect
the engine, the fuel supply is interrupted when
speed reaches this sector.

Reserve
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, the reserve level for
the BMW Z4 M Roadster/Z4 M Coupe is approx.
2.6 US gallons/10 liters.
Coolant temperature
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, your BMW Z4 M Road-
ster/Z4 M Coupe is not equipped with a coolant
thermometer.
Should the coolant and thus the engine become
too hot, a warning lamp will come on in the
instrument cluster.
Red warning lamp
The engine is overheated. Reduce your
speed immediately and pull over at a
suitable location. Switch off the engine
and allow it to cool down. Contact your nearest
BMW Center or a workshop that works accord-
ing to BMW repair procedures with correspond-
ingly trained personnel.
Do not open the hood, otherwise there is
a risk of injury from scalding.<
Yellow warning lamp
The engine is too warm. Continue driv-
ing, but in a moderate manner, so that
the engine can cool down.
If the warning lamp comes on again, have the
engine checked without delay.
Engine oil thermometer
The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed the maximum temperature of
3007/1506.
If the engine oil temperature is too high, the per-
missible engine speed, and thus the available
engine output, is reduced.

cumstances.<
Alternative oil grades
If a high-performance synthetic oil approved by
BMW should be unavailable, you may use small
volumes of other oils for topping up between oil
changes. The following data must appear on
the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or SAE 10W-40
>Specification
preferred: API SJ/CF
alternative: API SJ, also SK, SL, S...
Low ambient temperatures
The oils used by BMW at the factory for your
vehicle model can be used at virtually all ambi-
ent temperatures. However, if the vehicle is
operated for a longer period at temperatures
below –47/–206, your BMW Center will be
glad to recommend a suitable oil.
