For you 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 Ð that is, 15 %
MTBE or 3% methanol plus an equivalent
amount of co-solvent Ð will not void the
applicable warranties respecting defects in
materials or workmanship. Field experi-
ence has indicated significant differences
in fuel quality Ð volatility, composition, addi-
tives, etc. Ð among gasolines offered for
sale in the United States and Canada. The
use of poor quality fuels may result in drive-
ability, starting and stalling problems espe-
cially under certain environmental
conditions such as high ambient tempera-
ture 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 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 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 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
damage 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 Accesso-
ries and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW
centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones Ð including operation of
any portable cellular phone from within the
vehicle without using an externally
mounted antenna Ð or transceiver equip-
ment, for instance, CBs, walkie-talkie, ham
radio or similar accessories, may cause
extensive damage to the vehicle, compro-
mise 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.

of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part.

Technology for comfort, convenience and safety
92 Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving
conditions, varying from performance-
oriented during cornering to smooth and
comfort-oriented when the vehicle is
proceeding in a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive During vehicle operation, the system
continuously runs through closed-loop
control cycles lasting only fractions of a
second. In case of malfunction
The symbol will light up, accompa-
nied by a status message in the
Check Control panel. Please take
note of the additional information in the
Control Display panel.
You can find more detailed information on
the Check Control starting on page 80.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater
tendency to tilt during cornering and in
crosswinds.
If a status message appears in the Check
Control panel, accompanied by a red
symbol, the hydraulic fluid in the reservoir
may have fallen to below the minimum
level, possibly owing to leakage in the
hydraulic system. Stop the vehicle and
switch off the engine immediately.
Please observe the additional instructions
provided in the Control Display panel.<
EDC Electronic Damping
Control*

The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.Comfort program The system automatically assumes opera-
tion in its Comfort mode each time you start
the engine; this mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load. Sport programActivate in "Settings" menu with the igni-
tion on.
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and
steering. RDC Tire Pressure Monitor*The conceptRDC monitors inflation pressures in all four
tires while you drive. The system provides
an alert whenever the inflation pressure
drops significantly below the specified
pressure in one or more tires.
To initialize RDC, start by checking the
inflation pressures in all four tires and
comparing them with those specified in the
chart on page 171, correcting them as
necessary. Then proceed to initialize the
system.

In the event of loss in tire pressure If the indicator lamp symbol in the Check
Control lights up in yellow, and a message
also appears, this indicates that the infla-
tion pressures in the tires have fallen to
below the specified level, which is normal
in every tire after a certain amount of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible.
Please take note of the additional informa-
tion in the Control Display panel.
If you are prompted to check the tire
pressure shortly after a correction has
been made, this indicates that the
corrected values were not accurate. Please
check the inflation pressure again and
make corrections according to the inflation
pressure table. Then reinitialize the
system.< Flat tire If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. Replace the damaged tire.
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support RDC operation;
once the spare tire is installed, the pressure
in this tire will also be monitored following
system initialization.
Have the tires changed at your BMW
center. Your BMW center has the informa-
tion needed for working with RDC and is
equipped with the necessary special
tools. radio frequency as RDC can generate inter-
ference signals that may prevent the
system from operating as intended. The symbol will appear in yellow in the
Check Control panel and a message will
appear.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, additional
wheels with RDC electronics are on board.
Please refer to the additional information
supplied in the Control Display, and have
the system inspected at your BMW center.
Self-leveling suspension*

In the event of malfunction
A Check Control message
appearing together with this symbol
indicates a malfunction in the self-
leveling suspension. Please take note of
the additional information in the Control
Display panel.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, you should respond by immedi-
ately proceeding to the nearest BMW
center. Drive with appropriate caution in
the meantime. The vehicle has reduced
ground clearance and driving comfort may
be noticeably reduced. Even if the attitude
of the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
Adaptive brake lamp The adaptive brake lamp indicates the
intensity with which you are applying your
brakes to drivers of following vehicles.

Towing
Even if the transmission is in perfect
working order, you should always
remember to disengage the transmission
lockout manually before towing the vehicle.
Failure to observe this precaution could
result in automatic activation of the trans-
mission lockout while the vehicle is being
towed.<
Releasing transmission lockout manually,
refer to page 70.
Tow fittingThe threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment lid, refer to page 181, and
should always remain in the vehicle. This
fitting, which fits the tow sockets on both
the front and the rear of the vehicle, is
intended exclusively for use in towing the
vehicle on paved roads.
Access to tow sockets Press the arrow symbol to push out the
cover. Front
Rear
Screw the tow fitting in until it
bottoms firmly. If this is not done, the
threads could be damaged.
Never attempt to tow or tie down the
vehicle using suspension components, as
this could lead to damage that might ulti-
mately result in an accident.<
To avoid jerking and the associated
stresses on vehicle components when
towing, always use either a tow bar or a
nylon rope.
Keep the vehicles in line, taking care
to avoid towing at an offset angle, and
make certain that the tow rope connecting
the two vehicles is tight before starting
off.<
Towbars The tow fittings used should be on the
same side on both vehicles.
Should it prove impossible to avoid
mounting the tow bar at an offset angle,
please observe the following:
