Steering locked The key can be inserted or removed in
this position only.
To lock the steering column after you
have removed the key, turn the steering
wheel until you hear it lock.
If the key is not removed, an acoustic
signal sounds after the driver's door
has been opened.
Steering unlocked Individual electrical accessories are
ready for operation.
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. Ignition switched onAll electrical equipment and accesso-
ries are available for use. 1 Engage the parking brake
2 Put manual-shift gear lever in idling
position
3 Step on 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 igni-
tion key immediately when the engine
starts.
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.<
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
begin driving immediately at a
moderate engine speed.<

Parking brake Manual transmission
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.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
gear or reverse may not be enough to
prevent it 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.
The shift lever's neutral plane is located
between 3rd and 4th gear.
When shifting from each gear into
"Neutral," the shift lever automatically
springs back to the gear lever's home
position.
When shifting gears in the
5th/6th-gear plane, be sure to
press the gear lever to the right in order
to prevent inadvertent selection of a
gear in the 3rd/4th-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 causes the clutch assembly
to wear out sooner.<
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.

Cruise control
Do not use cruise control on
winding roads, when high traffic
density prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice), or when the road
surface is loose (rocks, sand).<
To deactivate the system Press switch 3 repeatedly until the indi-
cator lamp in the instrument cluster
goes out.
The cruise control is also deactivated
when the ignition key is in position 0.
The speed stored in the memory is
deleted.To store and maintain speed as
well as to acceleratePress button 1 briefly:
The system registers and maintains the
current vehicle speed. Each additional
tap on the button increases the speed
by approx. 0.6 mph (1 km/h).
Press and hold button 1:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
records and maintains the current
speed.
If, on a downhill gradient, the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button 2 briefly:
Whenever cruise control is active,
your speed will reduce by approx.
0.6 mph (1 km/h) each time you tap
the button.
Press and hold button 2:
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the button, the
system records and maintains the
current speed.To cancel the cruise control When the cruise control is on, press
and hold button 3. The indicator lamp
will stay on.
You can use the cruise control again
whenever required by calling up the
speed that was stored last.
In addition, the cruise control is
canceled automatically:
>If the brakes are applied
>When pressing down the clutch pedal
>If the cruise speed is either exceeded
or not met for an extended length of
time (if you depress the accelerator
pedal and exceed the set speed, for
example).Recal the stored speedPress button 4:
The vehicle accelerates to and main-
tains the last speed stored.

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following instructions:
Because of its engineering design,
the BMW M3 is an especially high-
quality vehicle. It is in your best interest
to follow the break-in procedure very
closely. Doing this, you will create the
basis for a long, optimum service life.<
Engine and differential>Until a mileage reading of 1,200 miles
(2,000 km): drive at varying engine
and road speeds, but do not exceed
the following engine speeds 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.
>After you have monitored the break-
in period for 1,200 miles (2,000 km),
you can begin to gradually increase
both the engine speed and road
speed.
You should also comply with these
break-in procedures if the engine or
differential is replaced later in the
course of the vehicle service life.
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 systemApproximately 300 miles (500 km) must
elapse before the brake pads and disks
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 allow you to do so. To
avoid corrosion, repeat this procedure
from time to time.
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 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 shift
roughly.
Break-in procedures

106n
Disk brakesDisk brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
disks and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
disks by brake applications is not
reached.
If the brake disks are corroded, they will
tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
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.<
Driving notes While driving on wet roads or in heavy
rain, it is a good idea to apply light
pressure to the brake pedal every few
miles or kilometers. Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and disks.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS should ever fail, pump
the brakes if possible (refer to
page 109).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect. Stay
within the allowable engine speed
range. For further information, refer to
page 69.
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary. Should engine braking prove inade-
quate, you should still avoid extended,
continuous braking. Instead of main-
taining low to moderate pressure over
an extended period of time, you should
decelerate the vehicle by applying more
substantial force on the pedal (watch
for following traffic). Pause before
repeating the brake application. This
staggered braking technique allows the
brakes to cool in the intervals between
active braking phases, preventing over-
heating and ensuring that full braking
capacity remains available at all times.
Do not coast with the clutch
depressed, with the shift lever in
neutral or with the engine shut off. The
engine does not provide any braking
effect with the transmission in neutral or
with the engine shut off.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<

Winter operationBrakingWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface;
the resulting increase in braking
distance is considerable and should
always be kept in mind.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock:
Reduce the pressure on the brake
pedal until the wheels just start to roll
again while still maintaining enough
force to continue braking. Then
increase the pressure, reduce the pres-
sure when the wheels lock, reapply
pressure etc.
This staggered braking procedure will
reduce stopping distances while
helping you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal. Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces which
provide only poor or uneven traction.<
Skid control Depress the clutch and let up on the
gas. Countersteer carefully and attempt
to regain control of the vehicle.
ParkingEngage first or reverse gear. Depending
on the steepness of the incline, you can
apply the parking brake as well. In order
to prevent the parking brake pads from
locking due to frost or corrosion, dry
them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not light up
when the parking brake is
applied.<
