RefuelingFuel filler door
Always switch off the engine 
before refueling, as it is not 
possible to add fuel with the engine 
running, 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.
394de729
sport wagon
1. Release the right-hand panel in the 
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 filler cap carefully to 
prevent fuel from spraying out. 
Fuel spray may cause injury.
Do not attempt to continue adding fuel 
to the last drop, as this practice can 
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: approximately 18.5 gal. 
(70 liters), with a reserve capacity of
>BMW 525i, 530i: 2.0 gal. (8 liters)
>BMW 540i: 2.5 gal. (10 liters).
After refueling, close the filler cap 
carefully, continuing until you hear 
the detent engage. While closing, be 
sure not to squeeze the strap which is 
fastened to the cap. A loose or missing 
cap will activate the message "CHECK 
FILLER CAP" in the Check Control
* or 
the Check Filler Cap lamp
*.< 
The engine uses lead-free gasoline 
only.
Required fuel:
>Premium Unleaded Gasoline, 
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.<

gauge.
To protect the engine, the engine-
management system interrupts the fuel 
supply when you approach this sector.390us004
Indicates the current fuel consumption 
in mpg (in liters/100 km on Canadian 
vehicles). This allows you to see 
whether your current driving style is

minimum exhaust emissions.
When the vehicle is stationary, the 
display goes to "Maximum" (zero on 
Canadian models).390us005
When you switch on the ignition, the 
indicator lamp comes on briefly to 
confirm that the system is operational. 
If the indicator lamp stays on, there are

Certain operating conditions (such as 
those encountered in mountainous 
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
