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 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
drive 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.
Please contact the nearest BMW
center.
Do not continue driving, other-
wise, the engine could be
damaged because of inadequate lubri-
cation.

In addition, an acoustic signal is
sounded: a tire failure has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.

Ignition key positions0 Steering locked
1 Steering unlocked
2 Ignition switched on
3 Starting engineSteering locked The key can be inserted or removed in
this position only.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.
Once the ignition has been switched off
(ignition key in position 0 or removed),
the radio functions are still available for
approx. 20 minutes. Turn the radio back
on to use it.Steering unlocked You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation. 1. Engage the parking brake
2. Gearshift lever in idling position
3. Depress the clutch pedal
4. Turn the key to position 3 to 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.
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.

SMG II: refer to the instructions on
page 64.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard.<

Parking brake Manual transmission The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels. To engageThe lever engages automatically, 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 (arrow) and lower the lever.
If, in exceptional circumstances,
it should be necessary to engage
the parking brake while the vehicle is
in motion, do not pull the lever with
excessive pressure. Keep your thumb
pressed against the release button
while carefully pulling the lever up to
apply moderate pressure.
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.
While parking on a downhill road, set
the parking brake, as engaging even
the first or reverse gear may not be
sufficient to prevent the vehicle from
rolling away.<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.
Every time you shift gears, always
depress the clutch pedal all the way
down, pushing the gearshift lever into
the desired position.
When shifting gears in the 5th/6th-
gear plane, be sure to press the
gearshift lever to the right in order to
prevent inadvertent selection of a gear
in the 3rd/4th-gear plane.<

Reverse Select only when the vehicle is
stationary. Press the shift lever to the
left to overcome the resistance.
As you do this, the backup lamps will
turn on automatically when the ignition
key is in position 2.
Do not hold the vehicle in place on
slopes by slipping or "riding" the
clutch. Use the parking brake instead.
Riding the clutch causes the clutch
assembly to wear out sooner.<
The conceptThe sequential M gearbox SMG II is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG II is operated via two shift
paddles on the steering wheel and the
selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs (Drivelogic)
>Gradient assistance
>Upshift display (shift lights)
>Throttle blip
>Driving dependent functions:
The respective driving situation (e.g.
cornering, mountain driving, braking)
is detected by sensors and taken into
account accordingly for shifting, e.g.
to achieve optimum gear selection
during deceleration and subsequent
acceleration>Slip recognition at the rear axle for
increasing driving stability, e.g.
during downshifting on slippery road
surfaces
>Operating safety through protection
against misshifting.

The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
The gradient assistance must be reacti-
vated before each use.
Indicator lamp
The transmission indicator lamp
in the instrument cluster goes
out after the engine is started.
>If it does not go out, or if it lights up
during driving, a fault has occurred.
The available functions may be
limited under certain circumstances.
Drive carefully and with the Dynamic
Stability Control (DSC) activated.
Have the system checked by the
nearest BMW center
>If the indicator lamp flashes while
driving, the system is overloaded.
Avoid high loads until the indicator
lamp goes out again permanently.
Shift lightsTo achieve the best possible vehicle
acceleration with a sporty driving style
in the sequential mode, shift lights in
the instrument cluster indicate the
optimum shifting point shortly before
the maximum engine speed is reached.
1. When the maximum engine speed is
approached, yellow indicator fields
(shift lights) in the tachometer light
up consecutively to indicate the
approaching upshift time
2. Shift at the latest when the last indi-
cator field lights up red.Tire replacement, snow chainsFollowing a tire or wheel change and

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following suggestions.
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.<
Engine and differential>Up to 1,200 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)
Obey your local and state maximum
speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Vehicles with SMG II
* (refer to
page 64): refrain from using driving
program 6 in the sequential mode
during the break-in period.
>Following the break-in inspection at
1,200 miles (2,000 km), you can
gradually increase engine or road
speeds.
Follow the same break-in procedure if
either the engine or the differential is
replaced in the future.TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles (300 km).
Obey your local and state maximum
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 aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
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 long service life later on.
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions permit to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on
when the parking brake is
engaged.
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 Ð when
towing, for example Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). Drive cautiously during this
break-in period and do not press the
clutch or shift at high engine speeds.
Break-in procedures

105n
OverviewControlsMaintenanceRepairsDataIndex
Brakes: do not rest your foot on
the brake pedal while driving.
Even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.
Aquaplaning: when driving on wet or
slushy roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
phenomenon is referred to as aqua-
planing, or hydroplaning, and can lead
to partial or complete loss of traction,
vehicle control and braking effective-
ness.
Driving through water: do not drive
through water on the road if it is deeper
than 1 foot (30 cm), and then only at
walking speed. Otherwise the vehicle
can sustain damage to the engine, the
electrical systems and the transmis-
sion.<
The conceptThe Antilock Brake System (ABS) keeps
the wheels from locking while braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply
maximum brake pressure ("panic
stop"). Since the vehicle maintains
steering responsiveness, you can
nevertheless avoid possible obstacles
with a minimum of steering effort.
Pulsation at the brake pedal combines
with sounds from the hydraulic circuits
to indicate to the driver that ABS is in
its active mode.Cornering Brake Control (CBC)CBC is an advanced engineering
design of the ABS. When braking while
cornering at high speed or braking
during high lateral acceleration, or
when braking during a lane change,
vehicle stability is improved and
steering response is enhanced.
Brake fluid level Low brake fluid level in the reservoir
combined with longer than usual pedal
travel may indicate a defect in one of
the brake system's hydraulic circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary when stop-
ping, and the vehicle may exhibit a
slight tendency to pull to one side.
Brake distances may even be longer.
Please remember to adapt your driving
style accordingly.<

Towing the vehicleUse only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it will not be
possible to control vehicle handling. to page 137.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle1. Gearshift lever in neutral
2. Towing speed:
Max. 45 mph (70 km/h)
3. Towing distance:
Max. 95 miles (150 km)
4. Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signal indicators, horn and wind-
shield wipers remain operative, and
to prevent the steering lock detent
from engaging
5. Switch on the hazard warning system
(observe applicable legal regula-
tions).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to
prevent the steering lock from
engaging.
The steering and brakes are without
power-assist when the engine is off.
This means that increased effort is
required for steering and braking.c
