Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this in the
following section.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. The alternator drive
belt is defective or there is a malfunc-
tion in the charging circuit of the alter-
nator. Please contact the nearest BMW
center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive belt
is defective, increased steering effort is
also required.

<


Engine oil pressure

l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

<



Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 104 and 126.

lamp for Canadian models.

Refueling
Before filling the tank, switch off
the engine, as otherwise fuel
cannot flow into the tank and the
"Service Engine Soon" warning lamp
may come on, refer to page 22.<
Open the fuel filler cap:
To open the fuel filler door, turn the fuel
filler cap counterclockwise and remove
the cap. Place the filler cap in the
bracket attached to the fuel filler door.
Open the filler cap carefully. If you
do not, fuel could spray out.<
To unlock the fuel filler door manually in
the event of an electrical malfunction of
the central locking system, refer to
page 157.
367de391
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refu-
eling
>results in premature shutoff
>and will reduce the effect of the vapor
recovery system.
If the filler nozzle is operated correctly,
the fuel tank is full when it shuts off the
first time.
Tank capacity, approx. 13.5 gal.
(51 liters), incl. a reserve capacity of
approx. 2.1 gal. (8 liters).
Close the fuel filler cap:
Position the cap on the neck. Turn the
cap clockwise to the stop.
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
"Service Engine Soon" lamp.<
Close the fuel filler door.
When handling fuels, comply with
all of the applicable safety
precautions and regulations pertaining
to fuels.
Never carry spare fuel containers in
your vehicle. Whether they are empty or
full, these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<
