Refueling Fuel specifications
Before filling the tank, shut off the
engine. If you do not, fuel cannot
flow into the tank and the "Check En-
gine" warning lamp may come on.<
To open the fuel filler door, press
against its forward edge.
To unlock the fuel filler door if there is a
malfunction of the central locking sys-
tem, refer to page 178.
When handling fuels, comply with
all of the applicable safety precau-
tions and regulations pertaining to fuels.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an ex-
plosion, or lead to fire in the event of a
collision.<

Open the 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 at-
tached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>results in premature pump shutoff
>and will reduce the effect of the
recovery vapor system on the pump.
Close the fuel cap carefully after
refueling. A loose or missing cap
will activate the "Check Engine“ lamp.<
380de633
Use unleaded gasoline only.
Minimum octane requirement: 91 AKI.
BMW engines are equipped with knock
sensors and will adapt automatically
to different octane ratings, provided
that the minimum octane requirement
(87 AKI) is met.
Fuels with higher octane ratings will
provide enhanced performance and
lower fuel consumption, while the use
of fuels with lower octane ratings will
have the opposite effect.
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic convertor.<
AKI = Anti Knock Index

Energy control Fuel gaugeIndicates current fuel consumption in
mpg (in liters per 100 km on Canadian
vehicles). This instrument clearly
shows whether your current driving
style is conducive to economy and min-
imum exhaust emissions.
When the vehicle is stationary, the dis-
play goes to "Maximum" (zero on Cana-
dian models).380us005
When you switch on the ignition, the in-
dicator lamp comes on briefly to con-
firm that the system is operational.
If the indicator lamp stays on, there are
approx.
>BMW 740i/L 2.6 gallons (10 liters)
>BMW 750iL 3.2 gallons (12 liters)
remaining in the tank.
Tank capacity: Refer to page 197.
Certain operating conditions (such as
those encountered in mountainous ar-
eas) may cause the needle to fluctuate
slightly.380us006
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
