Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the key is turned. They each light up once for
different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding lamp does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
>Luggage compartment lid/tailgate
>Fuel filler door
>Storage compartment between the back-
rests
>Roadster: opened manual convertible top
Operating from outside
>Via the remote control
>Via the door lock
The anti-theft system is operated at the same
time. It prevents the doors from being unlocked
with the lock buttons or release handles. The
remote control is also used to switch the interior
lamps on and off. In addition, the alarm system
*
is armed or disarmed.
For further details of the alarm system
*, refer to
page23.
Operating from inside
By means of the button for central locking, refer
to page21.In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.

Opening and closing:
from inside
This button serves to unlock or lock doors and
the luggage compartment lid/tailgate when the
doors are closed, but does not activate the anti-
theft system. The fuel filler door remains
unlocked.
If only the driver's door was unlocked from the
outside and you press the button, then, with the
driver's door still open, the luggage compart-
ment lid/tailgate and the fuel filler door will
unlock, too. If the driver's door is closed, it will
be locked.
If you prefer, the central locking system is
activated automatically as soon as you
begin to drive. You can have the corresponding
adjustment made for each key specifically.<
Unlocking and opening
>Either unlock the doors together using the
button for the central locking system and
then pull the door handle above the armrest
or
>pull the release handle for each door twice:
the initial pull unlocks the door, and the sec-
ond one opens it.
Locking
>Either use the central locking button to lock
both doors simultaneously, or
>press down the safety lock button of a door.
To prevent you from being locked out, the
open driver's door cannot be locked using
the lock button.
Persons or animals in the vehicle could
lock the doors from the inside. You should therefore take the key with you when leaving
the vehicle so that the car can be opened from
the outside.<

Automatic transmission
1.Depress the brake.
2.Start the engine.
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. +57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting attempts in quick
succession or repeated starting attempts
during which the engine does not start. Other-
wise, the fuel is not burned or inadequately
burned; there is a danger of overheating and
damaging the catalytic converter.<
Switching off the engine
Do not remove the key while the vehicle is
still moving. Otherwise, the steering lock
would engage when the steering wheel is
turned.
When you leave the vehicle, always remove the
key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, otherwise the vehicle could start to
roll.<
You can have an acoustic signal set as a
reminder that the key is still in the ignition
switch after the driver's door has been
opened.<
Manual transmission
1.Turn the key to position 1 or 0.
2.Engage first gear or reverse gear.
3.Apply the parking brake.
Automatic transmission
1.With the car at a standstill, move the selec-
tor lever to position P.
2.Turn the key to position 1 or 0.
Parking brake
The parking brake is designed primarily to pre-
vent the vehicle from rolling when parked. It
operates against the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.
The parking brake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button 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 it with
excessive pressure. In doing so, continuously
press the button of the parking brake lever. Oth-
erwise, too violent an application of the parking
brake can overbrake the rear axle and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<

R Reverse
Select only when the vehicle is stationary.
N Neutral, idle
You can select this in a car wash, for example.
The vehicle can roll.
D Drive, automatic position
This position is designed for driving under all
normal operating conditions. All forward gears
are selected automatically.
Under normal operating conditions, fuel con-
sumption is lowest when you are driving in posi-
tion D.
Kickdown
Kick-down enables you to achieve maximum
performance.
Press the accelerator pedal beyond the full-
throttle resistance point.
Manual operation and Sport program
M/S
Move the selector lever from position D to the
left into the M/S range:
The Sport program is activated. This is indi-
cated by the display SD in the instrument clus-
ter. This position is recommended for a perfor-
mance-oriented driving style.
The Sport program is enabled automatically
when the Dynamic Driving Control system is
activated, refer to page44.
To use the automatic function again, move the
selector lever to the right into position D.
Shifting gears using the selector lever
When you press the selector lever forwards or
backwards, the manual mode is activated and
Steptronic changes gear. The instrument clus-
ter shows M1 through M6.
The transmission will only execute upshifts and
downshifts that will result in an appropriate
combination of vehicle speed and engine rpm.
For instance, downshifts that would result in
excessive engine speed will not be executed.
The desired gear will appear briefly in the
instrument cluster, followed by the actual gear.
Shifting gears via the shift paddles* on
the steering wheel
The shift paddles allow you to shift gears
quickly since your hands can remain on the
steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears while in auto-
matic mode, the transmission automatically
switches to manual mode.
>If you do not use the shift paddles for a cer-
tain amount of time and do not accelerate,
the transmission automatically switches
back to automatic mode.
If the selector lever is in the M/S gear
plane, manual mode remains active.
>To shift up, pull one of the shift paddles.
>To shift down, press one of the shift pad-
dles.
The instrument cluster shows M1 through M6.
The transmission will only execute upshifts and

Outside temperature warning
If the outside temperature drops to approx.
377/+36, the computer automatically
switches to the outside temperature display.
A signal also sounds and the display flashes for
a short time. There is an increased risk of black
ice.
After an outside temperature warning has
been issued, the computer switches back
to its previous screen. You can have this acti-
vated/deactivated.<
Black ice can also form at temperatures
above 377/+36. You should therefore
drive carefully on bridges and shaded roads, for
example, otherwise there is an increased risk of
an accident.<

55 liters. You can find information on refueling
on page82.

Service interval display
The remaining driving distance in miles/km until
the next scheduled service is displayed briefly
immediately after you start the engine or switch
on the ignition.
The words OILSERVICE or INSPECTION indi-
cate the type of service due next. The computer
bases its calculations of the remaining driving
distance on the preceding driving style.
A flashing message and a minus sign in front of
the number mean that the service interval has
already been exceeded by the number of miles/
kilometers shown on the display. Please sched-
ule an appointment with your BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
The extent of service work required can
be read out from the remote control by
your BMW Service Advisor.<
