Vehicle equipment

In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehicle, for example due to
the special options or national-market version
selected. This also applies to safety related
functions and systems.

Observe the following when

refueling

Note the following instructions for your
BMW 1-Series M Coupe that deviate from the
description in the Owner's Manual for Vehicle.

Fuel tank capacity

Approx. 14 US gal/53 liters, including the
reserve capacity of 2.1 US gal/8 liters.

Refuel as soon as possible once your
cruising range falls below 30 miles/

50 km; otherwise, engine functions are not
ensured and damage can occur.

Fuel specifications

Never use fuels labeled at the fuel pump as
metal-containing.

Do not use leaded gasoline or gasoline
with metallic additives such as manga-

nese or iron; doing so can cause permanent
damage to the catalytic converter and other
components.

Do not fill the tank with E85, i.e. fuel con-
taining 85X ethanol, nor with FlexFuel.

Otherwise, the engine and fuel supply system
will be damaged.

Required fuel

Super premium gasoline/AKI 93

Always use this premium grade fuel to obtain
maximum fuel economy and performance.
The minimum approved fuel grade is AKI 91.

Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise, the

engine could be damaged.

Use high-quality brands

Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10X ethanol or other
oxygenates with up to 2.8X oxygen by weight,
that is, 15X MTBE or 3X methanol plus an
equivalent amount of cosolvent, will not void the
applicable warranties with respect to defects in
materials or workmanship.

The use of poor-quality fuels may result in
drivability, starting and stalling problems

especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.
