Indicator and warning lamps

Technology
that monitors itself

Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. 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 drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the drive belt is defective, do not
continue driving. The engine could
be damaged due to overheating. If the
V-belt is defective, increased steering
effort is also required.

<


Engine oil pressure

l

Stop vehicle immediately and
switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct: please contact
the nearest BMW center.
Do not continue driving, other-
wise, the engine could be
damaged because of inadequate lubri-
cation.

<



Tire Pressure Warning (RDW)
In addition, an acoustic signal is
sounded: a flat tire has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
For additional information, refer to
page 78.
Brake hydraulic system

l

If the lamp comes on when the
parking brake is not engaged:
Check the brake fluid level. Before
driving further, be sure to read the addi-
tional information on pages 107
and 126.

Brake system Brake fluid level
If the brake warning lamp
comes on with the parking
brake released:
The brake fluid level is too low in the
reservoir (refer to page 126).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up: only the
minimum pad thickness still
remains on the brake pads. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Brake fluid Vehicle IdentificationIf the brake warning lamp comes on
and the parking brake has been
released: check the brake fluid level
and if necessary, fill it up to the "MAX"
mark.
For adding brake fluid or for deter-
mining and correcting the cause of
brake fluid loss, consult your BMW
center. Your BMW center is familiar
with the specifications for factory-
approved brake fluids (DOT 4).
Due to loss of brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced. Comply with the
instructions for this found on page 107.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the brake system's
safety and reliability, have the brake
fluid changed every two years by an
authorized BMW center. Refer also to
pages 71, 151 and to the Service and
Warranty Information Booklet (US -
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion inaccessible to children.
Do not spill brake fluid and fill the brake
fluid reservoir only as far as the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
with special body-cavity protectants, by
applying specially developed and
extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treat-
ment with a wax-based protectant is
applied. Regular maintenance makes
an important contribution to maintaining
the safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
programs designed to further improve
the durability of their finishes. Despite
this, regional environmental factors can
have negative effects on your vehicle's
finish. These should guide you in deter-
mining the frequency and extent of your
efforts to maintain the vehicle finish.
Depending upon material and type of
impact (perforation of paint layer),
physical stresses from sand, road salt,
gravel etc., can cause corrosion to
extend beneath the finish, starting at
the point of impact.Road dirt, tar spots, dead insects,
animal droppings (strong alkali effect)
and tree excretions (resins and pollen)
all contain substances capable of
causing damage when allowed to
remain on the finish of your vehicle
for any period of time (spots, etching,
flaking, separation in the top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other
environmental pollutants will damage
the vehicle's finish unless adequate
care is provided Ð even though this
is generally limited to the outside hori-
zontal surfaces.
In coastal regions, high levels of
atmospheric salt and humidity promote
corrosion.
In tropical zones, high humidity and
heavy ultraviolet radiation prevail, in
addition to temperatures of over 105 7
(+40 6) in the shade. Under these
conditions, light paints can reach tem-
peratures up to 175 7 (+80 6) and
dark ones up to 250 7 (+120 6).
Caring for the vehicle finish Regular washing is a preventive
measure against long-term effects from
substances that are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels
of air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive
substances. Failure to do so can lead to
changes in the paint's chemical
structure or to discoloration. Gasoline
spilled during refueling, oil, grease and
brake fluid should always be cleaned
away immediately, as should bird
droppings (finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use
cleaning fluid or alcohol with a clean
cloth or cotton pad to remove. Remove
tar spots with tar remover. After
cleaning, the affected areas should be
waxed to ensure continued protection.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic; switch on the
hazard warning flashers.
Switch on the hazard warning flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse gear and engage the parking
brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle.
Comply with all safety guidelines and
regulations.<
M Mobility system With the BMW M3, you will find an
M Mobility system for fixing flat tires.
With the aid of this system, you can
apply a liquid sealant to the inside of
the tire, thereby sealing off the
damaged area, and then continue
driving.
The M Mobility system makes trans-
porting a spare wheel superfluous,
thereby reducing the amount of weight
you have to carry around.
The M Mobility system is located in the
luggage compartment under the floor
panel:
1 Lift up the floor panel
2 Loosen the M Mobility system from
its storage location.
Note that the fluid bottle in the
system's sealant container must
be replaced every 3 years by your BMW
center if the system is not used.<

Battery Fuses
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and
storage. Secure the battery against
tilting in transit.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
For this reason, be sure that the brake
fluid is changed every two years,
regardless of the information displayed.
Please read the information on
page 126.<
If an electrical accessory should fail,
switch it off and check the fuse. In glove compartment1 Open the glove compartment and
turn the two white quick-release
fasteners outward. Spare fuses and
plastic tweezers are located on the
fuse holder
2 Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working
3 Replace a blown fuse, recognizable
by its melted metal strip, with a new
fuse that has the same color or
ampere rating.
A list of fuses, their respective ampere
ratings and the equipment in their
circuits is provided below the fuse
holder.
To close the fuse holder, snap it into
position at the top and turn the two
fasteners inward.
Do not attempt to repair a burned
fuse or replace it with a fuse
having a different color or ampere
rating. To do this could cause a fire in
the vehicle resulting from a circuit
overload.<
If the fuse continues to burn through,
have the problem taken care of by a
BMW center.
