Brake fluidBrake fluid level
Brake hydraulic system warning
lamp comes on, "Check brake
fluid" appears in the Check Con-
trol display: The brake fluid level
is too low in the reservoir.
Fill up to upper mark ("MAX" level visi-
ble through the transparent reservoir).
Any BMW center can provide you with
information on factory-approved brake
fluids (DOT 4).
Brake fluid loss results in extended
pedal travel. Refer to the information on
page 128.

Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the operating safety
of the brake system, have the brake
fluid changed every two years by your
BMW center. Refer also to the Service
Warranty Information Booklet (US mod-
els) or to the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is toxic and damages the ve-
hicle's paint. Always store brake fluid in
the original containers. Keep the con-
tainers tightly closed and out of reach
of children. Do not spill brake fluid. Do
not fill beyond the "MAX" level in the
reservoir. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Observe the following instructions
during bulb replacement carefully. If
you are not familiar with any of the pro-
cedures, consult your authorized BMW
center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn in to the surface, thus reducing the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, comply
with any instructions provided by the
bulb manufacturer.<

Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-startingIt is not possible to start the engine of
vehicles equipped with automatic trans-
mission by towing or pushing.
For instructions on jump starting, refer
to page 179.
Never attempt to use your vehicle to
push another car, as damage to the
energy-absorbing bumpers could
result.

transmission1 Place selector lever in position N
2 Towing speed:
Max. 45 mph (70 km/h)
3 Towing distance:
Max. 95 miles (150 km)
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging
5 Switch on the hazard-warning system
(observe country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key re-
mains in position 1 even when the
electrical system has failed to prevent
the steering lock from engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is re-
quired for steering and braking.<
