Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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

●

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, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

An alarm sounds at the same
time. 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, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.
For additional information: refer to
page 87
Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 114 and 129.

Starting the engine and driving off
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
drive off immediately at a moderate
engine speed.<
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.<
If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures
below about 57/–156 and at high
altitudes above 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period, but no longer than
20 seconds.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<
When driving, standing at idle or
parking the vehicle, take care to
avoid contact between the hot exhaust
system and flammable materials –
grass, hay, leaves, etc. Such contact
could lead to a fire, resulting in serious
personal injury and property damage.<

2. Gearshift lever in idling position
3. Start the engine. Do not press the
accelerator pedal. Do not actuate the
starter for too short a time. Do not
turn it for more than approx.
20 seconds. Release the ignition key
immediately when the engine starts.Sequential M gearbox with

3. Start the engine. Do not actuate the
starter for too short a time. Do not
turn it for more than approx.
20 seconds. Release the ignition key
immediately when the engine starts
4. Engage a driving position
5. Release footbrake and slowly
depress accelerator pedal.
With the engine running, the gear
indicator in the SMG Drivelogic
display flashes to indicate that a driving
position is engaged with the driver's
door open or if the hood is not closed
properly, refer to page 71.
If neither the pedals, the shift paddles,
nor the selector lever are actuated, then
the gearbox is automatically taken out
of gear after approx. four seconds. It
will then be necessary to move the
selector lever back to position N before
engaging the desired driving position.
Driving off is not possible with the hood
open.<

67
Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the
parking brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.

Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not provide ade-
quate resistance to rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox with
DrivelogicIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in
position N, a warning tone and the
flashing gear indicator in the SMG
Drivelogic display remind you that no
gear is engaged to secure the vehicle
against rolling.
The warning stops after approx. ten
seconds. If you move the selector lever
into a forward or reverse position dur-
ing this time, a gear is automatically
engaged.
Parking brakeThe parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button and lower the lever.

69
If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on slopes and inclined sur-
faces. Engaging a gear may not provide
adequate resistance to rolling, not even
in first or reverse gear.<
To avoid corrosion and one-sided
braking, apply the parking brake
lightly from time to time when coasting
to a standstill – at a traffic light, for
example – provided that it is safe to do
so.<
Manual transmission
When shifting gears in the
fifth/sixth gear plane, be sure to
press the gearshift lever to the right in
order to prevent inadvertent selection
of a gear in the third/fourth gear plane.
Do not hold the vehicle in place on
slopes by slipping or 'riding' the clutch.
Use the parking brake instead. Riding
the clutch leads to severe and prema-
ture clutch wear.<
ReverseSelect only when the vehicle is station-
ary. Press the gearshift lever to the left
to overcome the slight resistance.
When you select reverse the backup
lamps will light up automatically when
the ignition key is in position 2.

Service interval displayRemaining distance to next
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or higher or
after the engine is started.
The next service due appears with the
message OIL SERVICE or
INSPECTION, together with the dis-
tance remaining in miles – in kilometers
in Canada – before the next scheduled
service.
The computer bases its calculations of
the remaining distance on the preced-
ing driving style.
A flashing message and a '–' in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.
Check ControlDisplayWhen the ignition key is in position 2,
the following information and/or condi-
tions are indicated using symbols until
the conditions have been corrected.

headlamps, as well as the parking
lamps
2Door open
3Luggage compartment lid open
4Check brake and tail lamps
When you open the driver's door after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.

112Special operating instructions
Break-in proceduresTo ensure that your vehicle continues to
provide maximum economy throughout
an extended service life, we request
that you devote careful attention to the
following instructions.
Because of its engineering design,
the BMW M3 Convertible is an
especially high-quality vehicle. It is in
your best interest to follow the break-in
tips very closely. Doing this, you will
create the basis for a long, optimum
service life.The first 1,250 miles/2,000 km: drive
at varying engine and road speeds,
but do not exceed the following
engine or road speeds:
5,500 rpm or 105 mph / 170 km/h.
Always obey all official speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Vehicles with SMG Drivelogic, refer to
page 70: refrain from using driving pro-
gram 6 in the sequential mode during
the break-in period.
>Following the break-in inspection at
1,250 miles/2,000 km, you can grad-
ually increase engine or road speeds.
Please remember to observe the same
break-in procedures if either the engine
or the differential should have to be
replaced later in the course of the vehi-
cle's service life.TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
We thus ask you to drive with extra care
during the first 200 miles/300 km.
Always obey all official speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as hydroplaning, and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
Brake systemApprox. 300 miles/500 km must elapse
before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and an extended service life
later on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill – at a traf-
fic signal, for instance; use caution to
avoid posing a danger to other road
users.
You can prevent corrosion in the drums
by periodically repeating this proce-
dure.
The brake lamps do not come on
when the parking brake is set.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off – when tow-
ing, for example – substantially higher
levels of pedal force will be required to
brake the vehicle.<

3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached — do not
overfill.
Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: brake fluid level
too low, refer to page 18.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for determin-
ing 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 in brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced. Refer to the informa-
tion on page 114.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet for
US models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location inaccessible to children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

Repairing a flat tire
Precautions in case of a flat tire:
Stop the vehicle as far as possible
from passing traffic; switch on the haz-
ard warning flashers.
Turn the steering wheel to the straight-
ahead position and engage the steering
lock. Shift into 1st or reverse 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 necessary, set up your warning trian-
gle or portable hazard warning lamp on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.<
M Mobility systemYou will find an M Mobility system in
your BMW M3 Convertible for repairing
flat tires. With this system you can
apply a sealing liquid to the inside of
the tire that seals off the damaged point
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.
