RefuelingFuel filler door
Always switch off the engine
before refueling, as it is not pos-
sible to add fuel with the engine run-
ning, and attempts may also trigger the
Service Engine Soon lamp.<
To open the filler door, press on the
front edge.
In the event of an electrical malfunction,
you can also open the fuel filler door
manually:
sedan
1. Use the handle to lower the trim
panel on the right side of the luggage
compartment
2. Pull the button with the fuel pump
symbol.

luggage compartment with the
button and fold the panel down
2. Pull the button with the fuel pump
symbol.
If a subwoofer
* is installed, loosen the
T-screw and swing the subwoofer to
the side.
Always observe all safety precau-
tions posted at the service station
when handling fuel. Never carry spare
fuel containers in your vehicle. Whether
empty or full, these containers can leak,
cause an explosion, or lead to fire in the
event of a collision.<
Simple and environmentally
friendly
Open the fuel filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.
Do not top off. Topping off may cause
fuel spillage.<
Keep the filler cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature pump shutoff
>and will reduce the effectiveness of
the vapor recovery system on the
pump.

Refueling Fuel specificationsAs long as the filler nozzle is used prop-
erly, the fuel tank is full whenever the
nozzle shuts off the first time.
Refill early to avoid damaging the
catalytic converter; never attempt
to drive to the last drop of fuel in the
tank.<
Tank capacity: approx. 18.5 gal.
(70 liters), with a reserve capacity of
>BMW 525i, 530i: approx. 2.0 gal.
(8 liters)
>BMW 540i: approx. 2.5 gal. (10 liters).
Close the filler cap carefully after
refueling until a click is heard.

min. 91 AKI
AKI = Anti Knock Index
Never use leaded fuel, as it would
cause permanent and irreversible
damage to the oxygen sensor and the
catalytic converter.<

Tire inflation pressureThe inflation pressures are indicated on
a sticker attached to the B-pillar behind
the driver's door (visible with door
open).Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) for tires at ambient
temperature (refer also to the next
pages).
Vehicles with Tire Pressure Monitor
(RDC)
*:
After correcting tire inflation pressures,
reactivate the system, refer to
page 101.
390de697
Check tire inflation pressures on a
regular basis Ð at least twice a
month Ð and before every extended
journey. Incorrect tire pressure can lead
to driving instability, tire damage and
accidents.
Check the inflation pressure of the
spare tire also. Inflate the spare tire to
the highest pressure of any tire on your
vehicle.<
Comply with tire approval
specificationsThe inflation pressures in the tables
apply to BMW approved tire sizes and
tire manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers.
Your vehicle is equipped with tires that
not only meet US, but also European
standards. We recommend the exclu-
sive use of BMW approved tires.
