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

Multifunction steering wheel (MFL)

The controls integrated in the multi-
function steering wheel are provided so
that you can operate a number of ac-
cessories quickly and without being
distracted from traffic conditions. You
may operate:

>

Some of the functions of the radio,
the CD and cassette modes

>

The recirculated-air mode of the air
conditioner or

>The steering wheel heating
>The cruise control and
>Selected cellular phone functions.
In order to operate a system via
the MFL, the corresponding sys-
tem controls must be switched on.<
The illustration shows the maximum
possible number of controls, corre-
sponding to a full range of optional
equipment. Refer to the individual ac-
cessory manuals for more detailed de-
scriptions.

First-aid kit
The push-button flashes rhythmically
when the hazard flashers are on.
To help you to locate the switch, the
button is also lighted whenever the car
lamps are on.380de039
The hazard warning triangle is stored
underneath the luggage compartment
lid in the onboard tool holder where it is
quickly available.
Comply with legal requirements
which cover the availability of a
hazard warning triangle in the car.< 394de053
Stored between the rear seats. Pull the
lever (arrow) and fold the cover forward.
Some of the articles in the first-aid
kit may be used within a limited
time only. For this reason, check the ex-
piration dates of each of the items regu-
larly, and replace any whose expiration
dates have passed. You can acquire re-
placements in any drugstore or phar-
macy.

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

Tire inflation pressureThe inflation pressures are indicated on
a sticker attached to the B-pillar behind
the driver's door (visible with door
open). Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) with cold tires (cold =
ambient temperature).
For vehicles with Tire Pressure Control
(RDC)
*:
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 94.
460de163
Check tire inflation pressures reg-
ularly - at least every two weeks
and before beginning a longer trip. In-
correct tire pressure can otherwise lead
to tire damage and accidents.
Also check the inflation pressure of the
spare tire. Inflate the spare tire to the
highest inflation of any tire on your vehi-
cle.<
Comply with tire approval
specificationsThe inflation pressures in the table ap-
ply to tires from BMW-approved manu-
facturers. Your BMW center is familiar
with these pressures. Higher pressures
may be specified for tires from other
manufacturers. You will find a list of ap-
proved tires beginning on page 136.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW-approved
tires.
