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 – i.e. 15 % MTBE or
3% methanol plus an equivalent amount of
co-solvent – will not void the applicable
warranties respecting defects in materials
or workmanship. Field experience has indi-
cated significant differences in fuel quality –
i.e. volatility, composition, additives, etc. –
among gasolines offered for sale in the
United States and Canada. The use of poor
quality fuels may result in drivability, start-
ing and stalling problems especially under
certain environmental conditions, such as
high ambient temperature and high alti-
tude.
Should you encounter driveability prob-
lems that 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 recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.<
Important safety information!
For your own safety, use 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 thoroughly
tested by BMW to ensure optimum perfor-
mance when installed on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for dam-
age resulting from installation of parts and
accessories not approved by BMW.
BMW cannot test every product made by
other manufacturers to verify if it can be
used on a BMW safely and without risk to
either the vehicle, its operation, or its occu-
pants.Original BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW
retailers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones – including operation of
any portable cellular phone from within the
vehicle without using an externally mounted
antenna – or transceiver equipment – e.g.
C.B., walkie-talkie, ham radio or similar –
may cause extensive damage to the vehicle,
compromise its safety, interfere with the
vehicle's electrical system or affect the
validity of the BMW Limited Warranty. See
your BMW center for additional information.
Do not use key or remote control to lock
doors or luggage compartment with any-
one inside the car. Refer to the Owner's
Manual for more details.<
Maintenance, replacement or repair
of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part. This manual is supplemented by a Service
and Warranty Information Booklet for US
models or a Warranty and Service Guide
Booklet for Canadian models.
We recommend that you read this publica-
tion thoroughly.
Your BMW is covered by the following war-
ranties:
>New Vehicle Limited Warranty
>Rust Perforation Limited Warranty
>Federal Emissions System Defect
Warranty
>Federal Emissions Performance
Warranty
>California Emission Control System
Limited Warranty.

Notes
8 Detailed information about these warran-
ties is listed in the Service and Warranty
Information Booklet for US models or in the
Warranty and Service Guide Booklet for
Canadian models.
Reporting safety defects
The following only applies to vehicles
owned and operated in the US.
If you believe that your vehicle has a defect
which could cause a crash or could cause
injury or death, you should immediately
inform the National Highway Traffic Safety
Administration – NHTSA – in addition to
notifying BMW of North America, LLC,
P.O. Box 1227, Westwood, New Jersey
07675-1227,
Telephone toll-free 1-800-831-1117.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot
become involved in individual problems
between you, your retailer, or BMW of
North America, LLC.
To contact NHTSA, you may either call the
Auto Safety Hotline toll-free at
1-800-424-9393 or 366-0123 in
Washington, D.C. area, or write to: NHTSA,
U.S. Department of Transportation, Wash-
ington, D.C. 20590. You can also obtain
other information about motor vehicle
safety from the Hotline.

Indicator and warning
lamps
Technology that monitors itself
Indicator and warning lamps that are iden-
tified by
+ are tested for proper functioning
whenever the ignition key is turned. They
each light up once for different periods of
time.
If a fault should occur in one of these sys-
tems, the corresponding lamp does not go
out after the engine is started or it lights up
again while the vehicle is moving. The indi-
cated pages provide information on what
measures to take.

Driving
Ignition lock
0Steering locked
1Steering unlocked
2Ignition switched on
3Engine started
Steering locked
This is the only position in which the igni-
tion key can be inserted or removed.
After removing the key, turn the steering
wheel slightly to the left or right until the
lock engages.
If the key is not removed, an acoustic signal
sounds when the driver's door is opened.
Once the ignition has been switched off –
ignition key in position 0 or removed – the
radio functions are still available for approx.
20 minutes. Turn the radio back on to use it.
Vehicles with automatic transmission:
do not move the selector lever from
position P until the engine is running – igni-
tion key in position 2.
In order to turn the key back to position 0 or
to remove it, move the selector level into
position P first – Interlock.<
Steering unlocked
You will often find that it is easier to turn the
ignition key from position 0 to 1 if you move
the steering wheel slightly to help disen-
gage the detent.
Individual electrical equipment and acces-
sories are available for use.
Engine
Do not allow the engine to warm up while
the vehicle is stationary. Instead, begin
driving immediately at a moderate engine
speed.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and should
decrease as the engine warms up. If engine
speed does not decrease, service is
required.
To prevent the battery from discharging,
always deactivate electrical devices that
are not in use. Switch the ignition off when
the vehicle is not being driven.
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 unattended vehicle
with a running engine poses a safety haz-
ard.
When driving, standing at idle and parking
the vehicle, take care to avoid contact
between the hot exhaust system and flam-
mable materials – e.g. hay, leaves, grass,
etc. Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
Starting the engine
Do not press the accelerator pedal while
starting the engine.
Vehicles with manual transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine from
starting if the clutch is not depressed.<
Do not actuate the starter for too
short a time, but do not actuate it for
more than approx. 20 seconds. Release

When you switch on the ignition, warning
lamp 1 comes on briefly to indicate an
operational check.
Comes on while driving:
The engine has overheated. Switch off the
engine immediately and allow it to cool
down.
For checking the coolant level, refer to
page 80.
Service interval display
Remaining distance to next service
The displays shown in the illustration
appear for a few seconds when the ignition
key is in position 1 or after the engine is
started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the distance remaining in
miles – in kilometers in Canada – before the
next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driv-
ing style.
A flashing message and a "–" in front of the
number mean that the service interval has
already been exceeded by the distance
shown on the display. Please contact your
BMW center for an appointment.
Outside temperature
If the vehicle is not equipped with a com-
puter, the display in the instrument cluster
always shows the outside temperature.
Clock
If you wish to have a permanent time dis-
play, you can have it appear in the car radio
display, refer to the Owner's Manual for
Radio.
You can set the clock and the time display
in the car radio as follows.
