BMW Universal Transmitter
*
1. Program the BMW Universal Trans-
mitter as described above under
"Programming" on the previous page
2. Press and hold the programming key
on the receiver of the device for
about two seconds or until the pro-
gramming lamp on the device comes
on
3. Press the desired channel key of the
BMW Universal Transmitter three
times.
If you have additional questions,
please consult your BMW center.<
Clearing the channel keys
Read and comply with the safety
precautions on page 115.<
The memory of individual channel keys
cannot be deleted. However, the three
channel keys can be cleared together in
the following manner:
>Press and hold the two outer channel
keys of the BMW Universal Trans-
mitter until the indicator lamp flashes,
and then release the keys.
All of the channel keys are cleared.
User's informationDo not use this BMW Universal Trans-
mitter with any garage door opener that
lacks safety "stop" and "reverse" fea-
tures as required by federal safety stan-
dards (this includes any garage door
opener model manufactured before
April 1st, 1982).
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful
interference, and
(2) This device must accept any inter-
ference received, including interference
that may cause undesired operation.

Brake systemBrake fluid level If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the two brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and the vehicle may exhibit
a slight tendency to pull to one side
when the brakes are applied. Braking
distances may also be longer. Please
remember to adapt your driving style
accordingly.<
Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of con-
tamination on the brake pads. The pads
must exert a certain minimal level of
pressure against the rotors for the disc
brakes' inherent self-cleaning effect to
remain effective; the pressure available
under the above conditions may not
provide adequate cleansing.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to
ensure that this maneuver does not
pose a hazard to you or to other road
users. The heat generated in this pro-
cess helps dry the pads and rotors to
ensure that your brake system will
respond with undiminished efficiency
when you need it.When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
Do not coast with the clutch
depressed or with the transmission
or selector lever in Neutral. Do not coast
with the engine switched off. The engine
provides no braking effect when the
clutch is depressed and there is no
power-assist for braking or steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and brake
pedals and obstruct their movement.<
Brake pads
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Tire replacement Wheel and tire combinationsUniform Tire Quality GradingQuality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.< Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 2601 indicates that the tire was
manufactured in Week 26 of the year
2001.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
The right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your par-
ticular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. If non-approved wheels and tires
are used, BMW cannot evaluate their
suitability, and therefore cannot be held
liable for driving safety.<
BMW has tested certain tires for each
tire size, rated them according to road
safety and approved them. Your BMW
center can inform you which tires have
been tested in this way. Observe pos-
sible national guidelines, e.g. regarding
entry into vehicle documents.
The correct wheel and tire combi-
nation affects different systems
such as ABS, ATC, ASC+T/DSC.
The function of these systems is
impaired if improper wheel and tire
combinations are used.
Always ensure that all of the tires
mounted on the vehicle are the same
series, from the same manufacturer and
with the same tread pattern. If you have
to mount the spare tire in response to a
flat tire, etc., you should remount a tire
of the correct specifications as soon as
possible.<
The use of rims and wheel bolts
that do not meet the specifica-
tions of the original factory-installed
equipment will affect the safe operation
of your vehicle and may cause an acci-
dent and personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle con-
trol.< Storage Store tires in a cool, dry place, pro-
tecting them against light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
