2001 BMW 540I SEDAN fuel cap

28n
RefuelingFuel filler door
Before refueling, shut the engine
off. If the engine is running, fuel
cannot be filled into the tank and the
Service Engine Soon lamp may come
on.<
To open the filler door, press on the
front edge.
To unlock the filler door if the central
locking system fails, refer to page 198.
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.< 394de011
Simple and friendly to the environment
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
attached to the fuel filler door.390de603
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 vapor
recovery system on the pump.
As long as the filler nozzle is used prop-
erly, the fuel tank is full whenever the
nozzle shuts off the first time.
Tank capacity: refer to page 223.
Close the filler cap carefully after
refueling until a "click" is heard.
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 Service Engine
Soon lamp.<

Tachometer Energy control Fuel gaugeNever allow the engine to operate with
the needle in the red overspeed zone of
the gauge.
To protect the engine, the engine-man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power.390us004
Indicates current fuel consumption in
mpg (in liters per 100 km on Canadian
vehicles). This instrument shows
whether your current driving style is
conducive to fuel economy with mini-
mum exhaust emissions.
When the vehicle is stationary, the dis-
play goes to "Maximum" (zero on Cana-
dian models).390us005
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. >2.0
gal (8 liters) –
BMW 525i, BMW 530i
>2.5 gal (10 liters) – BMW 540i
remaining in the tank.
Tank capacity: refer to page 223.
Certain operating conditions (such
as those encountered in mountainous
areas) may cause the needle to fluctu-
ate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 390us006
