Do not actuate the starter for too
short a time, but do not actuate 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.<
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 extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 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
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup 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.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<

Switching off the engineTurn the ignition key to position 1 or 0.
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.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces. Placing the lever in gear may not
provide adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in Park.<
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 – see arrow – and lower the
lever.

63
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.
Vehicles with manual transmission:
Always engage the parking brake when
parking on slopes and inclined sur-
faces. Placing the lever in gear may not
provide adequate resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in Park.<
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
example – provided that it is safe to do
so.<
Manual transmission
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
premature clutch wear.<
ReverseSelect only when the vehicle is station-
ary. Press the shift lever to the left to
overcome the slight resistance.
As you do this, the backup lamps will
light up automatically when the ignition
key is in position 2.

Automatic transmission with Steptronic*You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the D position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by + or –. Whenever you want to use
the automatic transmission mode again,
move the selector lever to the right into
the D position.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.Selector lever positions P R N D M/S + –Starting the engineThe engine can only be started in selec-
tor lever positions P – for Park – or N –
for Neutral.
Range selectionA detent prevents inadvertent shifts to
the Reverse or Park selector lever posi-
tions. To disengage the detent, press
the button on the front side of
the selector lever button – see arrow.
While the vehicle is stationary and
before shifting out of Park or Neu-
tral, depress the footbrake in order to
disengage the selector lever's lock
mechanism – Shiftlock.
Hold the footbrake down until starting
off. The vehicle will otherwise "creep"
when a drive position is engaged.<
To prevent the vehicle from start-
ing off on its own, always move
the selector lever to position P and
engage the parking brake before leav-
ing your vehicle with the engine run-
ning.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard.<
PParkSelect only when the vehicle is station-
ary. Transmission locks to prevent rear
wheels from turning.RReverseSelect only when the vehicle is station-
ary.NNeutralSelect only when stopping for an
extended period.DDrive – automatic shift programThis position is designed for driving
under all normal operating conditions.
All forward gears are available.

KickdownIn the kickdown mode, you achieve
maximum acceleration and top speed
in position D.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S manual operation and Sport
ProgramMove the selector lever from D to M/S
to activate the Sport Program; SD
appears in the display panel. The M/S
mode is recommended for
performance-oriented driving.
Once in the M/S mode you can tap the
selector lever to switch the automatic
transmission from the Sport Program to
its manual selection mode.
This mode allows you to execute
upshifts manually by tapping the lever
toward +, while downshifts are selected
by tapping in the – direction. The dis-
plays M1 through M5 appear in the dis-
play panel to indicate your current gear
selection.
The Adaptive Transmission Control
(ATC) executes upshifts and downshifts
only when the new gear will provide a
suitable combination of engine and
road speed, i.e., ATC will not execute
downshifts if the engine speed is too
high. The desired, then the actual gear,
briefly appear in the instrument cluster.
To accelerate quickly in the man-
ual mode for maneuvers such as
passing another vehicle, shift down
manually or employ the kickdown
mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.

Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only operate in 3rd and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized BMW center.
Never work in the engine com-
partment when a drive gear – for-
ward or reverse – is engaged. If you do
this, the vehicle could move.<
For towing or jump-starting, refer to the
information beginning on page 147.
