Everything under control
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.
Fuel gauge
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
temperature gauge.
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 175 7/80 6 and 250 7/120 6. Do
not exceed the maximum temperature of
300 7/150 6.
Service interval display
Regardless of your service requirements,
have the breaking-in inspection per-
formed by your BMW center after driving
1,200 miles/2,000 km. <

operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up in red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top up if necessary. If the oil level is correct,
please contact your nearest BMW center or a
workshop that works according to BMW repair procedures with correspondingly trained per-
sonnel.
Do not continue driving, otherwise the
engine could sustain serious damage
from inadequate lubrication. <
Engine oil level
The warning lamp lights up in yellow
while you are driving. A signal also
sounds.
The oil level is at the absolute minimum; check
engine oil level using dipstick 7 and refill as
soon as possible. Do not drive more than
30 miles/50 km before refilling.
