Notes

Status at time of printing

BMW pursues a policy of continuous,
ongoing development that is conceived
to ensure that our vehicles continue to
embody the highest quality and safety
standards combined with advanced,
state-of-the-art technology. For this
reason, the features described in this
Owner's Manual could differ from those
in your vehicle. Nor can errors and
omissions be entirely ruled out. You are
therefore asked to appreciate that no
claims can be recognized on the basis
of the data, illustrations or descriptions
in this Owner's Manual.

For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight – that is,
15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent – will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality – volatility, composition, addi-
tives, etc. among gasolines offered for
sale in the United States and Canada.
The use of poor-quality fuels may result
in driveability, starting and stalling
problems especially under certain envi-
ronmental conditions, such as high
ambient temperature and high altitude.
Should you encounter driveability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Obey all applicable safety rules when
you are handling gasoline.

<

Important safety information!
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Original
BMW Parts, you simultaneously acquire
the assurance that they have been thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damage resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product made
by other manufacturers to ascertain
whether it can be used on a BMW
safely and without risk to either the
vehicle, its operation, or its occupants.
Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on
using these items, are available from all

3Starting the engine
Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position P until the engine is running –
ignition key position 2.
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 or removed until
the selector lever is in position P.<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing 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.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition – ignition key in position
0 or key extracted. Simply switch it
back on.Steering unlockedYou 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.
Starting the engineBefore starting>Engage the parking brake
>Gearshift lever in neutral, or, with an
automatic transmission, selector
lever in position P
>Depress the clutch pedal.
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.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable materi-
als – grass, hay, leaves, etc. Such con-
tact could lead to a fire, resulting in
serious personal injury and property
damage.<
>Start the engine. Do not press the
accelerator pedal.

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 designed primarily
to prevent the vehicle from rolling when
it is 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.

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 mode again, just shift the
selector lever toward the right to posi-
tion D.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.Selector lever positionsP 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. Otherwise the vehicle will "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.<
