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
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.

Regardless of your service requirements,

Refueling
Note when refueling
In contrast to the descriptions in the Owner's
Manual for the BMW Z4, please take note of the
following differences for your BMW Z4 M Road-
ster/Z4 M Coupe.
Fuel tank capacity
Approx. 14.5 US gallons/55 liters, including the
reserve capacity of approx. 2.6 US gallons/
10 liters.
Do not drive until the tank is empty. Oth-
erwise, the engine may not operate prop-
erly and damage could result.<
Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended. How-
ever, you may also use gasoline with less AKI.
The minimum AKI Rating is 89.
Do not fill the tank with any gasoline
below the specified minimum fuel grade;
otherwise engine damage could result.<

Engine oil
Like fuel consumption, engine oil consumption
depends on your driving style and the vehicle's
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.

The warning lamp lights up in yellow
after the engine is switched off. A signal
also sounds.
Check the engine oil level using dipstick7 at the
earliest opportunity, e.g. when you stop to
refuel, and refill engine oil.
The warning lamp lights up in yellow
within 30 seconds after the engine is
started:
The oil level sensor is defective. Have the sys-
tem checked as soon as possible.
Checking the oil level
1.Position the vehicle on a level surface.
2.Switch off the engine when it is at operating
temperature.
3.After approx. 1 minute, pull dipstick 7 out
and wipe it off with a clean, lint-free cloth,
paper towel or something similar.
4.Carefully push the dipstick fully into its tube,
then pull it out again.
The oil level must be between the two
marks on the dipstick.
The oil volume between the two marks on the
dipstick corresponds to approx. 1.4 US quarts/
1.3 liters.
Adding engine oil
Do not add oil until the oil level has dropped
almost to the lower mark on the dipstick, refer to
Checking the oil level.
Do not add oil beyond the upper mark on
the dipstick, otherwise excessive oil can
lead to engine damage.<
Before you check the engine oil level after add-
ing oil, restart the engine and let it run to obtain
a correct reading. Then proceed as described
under Checking the oil level.
BMW engines are designed to operate
without oil additives; the use of additives
could even lead to damage in some cases. The
same applies to the transmission and differen-
tial as well as to the power steering.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For this
reason, thoroughly wash any areas of skin that
have come into contact with oil using soap and
water.
Keep oils, greases, etc. out of the reach of chil-
dren and comply with the warnings on the con-
tainers. Otherwise, health hazards may result.<
Comply with the applicable environmen-
tal regulations concerning the disposal of
used oil.<
Recommendation: have the oil changed at your
BMW Center.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
only approves specific oils after confirming their
suitability for use in its vehicles with extensive
testing.
