Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW mon-
itor themselves automatically, both dur-
ing engine starts and while you are driv-
ing. Indicator and warning lamps that
are identified by "

l

" are tested for
proper functioning whenever the igni-
tion 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 below.

Red: Stop immediately

Battery charge current

l

The battery is no longer being
charged. There is a malfunction
of the alternator ribbed V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the V-belt is defective, do not
continue driving. The engine could
be damaged due to overheating. If the
ribbed V-belt is defective, increased
steering effort is also required.

<


Engine oil pressure

l

Comes on while the engine is
running and the "Stop! ENGINE
OILPRESS" message appears in the
Check Control:
Stop vehicle and switch off engine im-
mediately. Check level of oil in engine,
top up as required. If oil level is correct:
Please contact the nearest BMW cen-
ter.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.

<



Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 128 and 147.
Also comes on with the message
"Check brake pads" in the Check Con-
trol.

Antilock Brake System (ABS)

l

The ABS system has been de-
activated because of a system
fault. Conventional braking efficiency is
available without limitations. Please
have the system inspected by your au-
thorized BMW center.
For additional information: Refer to
page 125.

Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)

*
l

The ASC+T/DSC has been switched off
or has been deactivated because of a
malfunction. In the event of a malfunc-
tion, have the system checked by your
authorized BMW center. For additional
information: Refer to page 92.

Check Engine lamp

l

If the indicator lamp comes on
either continuously or intermit-
tently, this indicates a fault in the emis-
sions-related electronic systems. Al-
though the vehicle remains operational,
you should have the systems checked
by your BMW center at the earliest pos-
sible opportunity.
For additional information: Refer to
OBD connector on page 158.

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.<
384de011
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
