Notes

Status at time of printing

BMW pursues a policy of continuous,
ongoing development 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
environmental 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
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 on the
market to determine 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

Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position P until the engine is running,
ignition key position 2.
To turn the key to position 0 or to
remove it, first move the selector lever
to position P – Interlock.<
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
you hear the lock engage.
If the key is not removed, an acoustic
signal sounds when the driver door is
opened.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition, ignition key in position 0
or key removed. 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
>Ensure that the gearshift lever is in
neutral, or, with an automatic trans-
mission, that the selector lever is in P
>Depress the clutch pedal at low tem-
peratures.
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.<
