National-market specification for
leaded fuel*
In addition to the fuel grades listed
above, you can also fill the tank with
leaded petrol.
The minimum approved grade is
91 RON.
Diesel engine
>
Diesel oil to DIN EN 590 standard.
Do not use rapeseed oil methyl-
ester (RME) or bio-diesel or you
will risk damaging the engine.
<
Winter diesel
To ensure that the diesel engine oper-
ates reliably during the cold season of
the year, it must be run on winter-grade
diesel oil, which garages usually sell
during the period in question. Fuel filter
heating is installed as standard equip-
ment to prevent the fuel from solidifying
during operation.
Additives are not approved,
because their use could result in
damage to the engine.

Tyre pressures
Tyre pressures in bar gauge pressure
are shown on the driver's door post
(visible when the door is open).
Checking tyre pressures
All pressures are listed in bar (gauge
pressure), with the equivalents in kPa
and pounds per square inch, for tyres at
ambient temperature, see tyre-pressure
table below.
When towing a trailer, always use the
values for the higher load.
Cars with tyre pressure control (RDC):
After correcting the tyre pressure, reac-
tivate the system; see page 84.
Check tyre pressures regularly (at
least every two weeks and before
starting a long journey). Incorrect tyre
pressures can adversely affect the car's
roadholding and cause tyre damage,
which could result in an accident.
Also remember to check the pressure in
the compact spare tyre or full-size
spare tyre.
The spare wheel should be inflated to
the highest pressure applicable for any
of the car's tyres.
<
Make sure that only approved
tyres are fitted
These tyre pressures apply to makes of
tyre and tyre sizes approved by BMW
and known to BMW Service. If other
makes of tyre are fitted to the car,
higher tyre pressures may be needed.
