Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own indi-
vidual preferences. In engineering your
vehicle, BMW has incorporated a
number of options for personal adjust-
ment that can be programmed into your
vehicle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle
("Vehicle Memory") or the individual
("Key Memory"). Provided that each
person has a separate remote-control
key, you can have your BMW center
enter two personal adjustments for two
different individuals into the system.463de029
The system then relies on a bilateral
data exchange to identify the individual
user and dial in the selected settings
whenever the remote control unit is
used to disengage the door locks.
In order for you to distinguish between
different keys, colored decals are sup-
plied together with the keys.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems. A
few examples follow below:
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your
vehicle
>Activates/deactivates the "Follow me
home" function.Examples for Key Memory:
>Locks the vehicle when you start off
>Automatically adjusts the driverÕs
seat, the exterior mirrors and the
steering wheel position to your per-
sonal programmed settings when you
unlock the vehicle
>The automatic climate control
assumes your preset comfort settings
when you unlock the vehicle.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

Tire Pressure Monitor (RDC)*Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly (which is normal for any tire),
the yellow indicator lamp comes on or
the message "CHECK TIRE PRES-
SURE" appears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection 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.<
Flat tireIf there is a tire failure with a loss of
inflation pressure, the red indicator
lamp comes on or the message "TIRE
DEFECT" appears in the Check Control.
In addition, a gong sounds.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the flat
tire.
The spare tire which is available in
your vehicle as standard equip-
ment is equipped with the electronics
required for RDC and, following activa-
tion of the system, is also monitored
after it is mounted.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed at your
BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceDuring the period of the malfunction,
the yellow indicator lamp comes on
or the message "TIRECONTROL INAC-
TIVE" appears in the Check Control.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Parking lamps (side marker
lamps)
With the switch in this position,
the front, rear and side vehicle
lighting is switched on.
For lighting on one side for parking as
an additional feature, refer to page 104.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps (side marker lamps)
remain on.
390de732
"Follow me home":
When you activate the headlamp
flasher after parking the vehicle and
switching off the lamps, the low beams
will come on for a brief period. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhen the driver's door is opened with
the ignition key in position 0 an acoustic
signal will sound for several seconds to
remind you that you have forgotten to
switch off the lamps
.
Vehicles with alphanumeric Check
Control
*:
The reminder is provided by the Check
Control, refer to page 87.
Daytime driving lamps
*
The headlamps are automatically
switched on for daytime driving in
ignition key position 2.
Automatic headlamp control
*
When the switch is set to this
position the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light ( in tunnels, at dusk, etc.)
as well as rain and snow.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lamps should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlamps on manu-
ally.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

OverviewControlsMaintenanceRepairsDataIndex
The conceptThe BMW Universal Transmitter
replaces up to three hand-held transmit-
ters to control different devices such as
a garage door opener, alarm systems or
a door locking system. The BMW Uni-
versal Transmitter recognizes and
"learns" the transmitted signal from each
of the original hand-held transmitters.
The signal of an original hand-held
transmitter can be programmed on one
of the three channel keys. Following
that, each of the devices can be actu-ated with the appropriately-programmed

channel key. The indicator lamp flashes
to confirm transmission of the signal.
Before you sell your vehicle, the pro-
grammed channel keys should be
cleared. Refer to page 117 for the
description of this process.
To prevent potential injuries or
damage during the programming
operation and before every remote trig-
gering of a programmed device using
the BMW Universal Transmitter, be sure
that there are no persons, animals or
objects within the range of movement
of the respective device. Also, comply
with the safety precautions of the orig-
inal hand-held transmitter.<
To Canadian residents:
During programming, your hand-
held transmitter may automatically stop
transmitting after two seconds. This
may not be long enough to program the
BMW Universal Transmitter. If you are
programming from one of these hand-
held transmitters, the Universal Trans-
mitter's lamp may begin to flash in a
series of double flashes. If this occurs,
continue to hold the key on the Uni-
versal Transmitter while you reactivate
your hand-held transmitter. You may
have to repeat this function several
times while programming.<
Before programming, read the
"User's information" section on
page 117.<
The original hand-held transmitter
If this symbol is depicted on the
packaging or in the user's
instructions for the original
hand-held transmitter, it may be
assumed that this original hand-held
transmitter is compatible with the BMW
Universal Transmitter.
Checking for the conversion codeIn order to determine whether the orig-
inal hand-held transmitter is equipped
with a conversion-code system, you
may either refer to the instructions for
the original hand-held transmitter or
program a channel key as described in
the left column on page 116 under
"Programming."
Following that, press and hold the pro-
grammed channel key of the BMW Uni-
versal Transmitter. If the indicator lamp
of the BMW Universal Transmitter
flashes rapidly for two seconds and
then stays on continuously, the original
hand-held transmitter is equipped with
a conversion-code system. If the con-
version-code system is available, pro-
gram the channel keys as described in
the right-hand column on page 116
under "Programming a hand-held trans-
mitter with change code."
If you have additional questions,
please consult your BMW center
or call 1-800-355-3515.<

Special characteristics of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While all-season tires (M+S designa-
tion) provide better winter traction than
summer tires with the load ratings H, V,
W, Y and ZR, they generally do not
achieve the performance of winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire inflation
pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and should thus
be replaced.
Comply with the specified tire inflation
pressures and be sure to have the
wheel and tire assemblies balanced
every time you change the wheels/tires.BMW narrow-link snow chains
are
approved exclusively for use in combi-
nation with winter tires on the rear
wheels only. Comply with all manufac-
turer's safety precautions when
mounting the chains. Do not exceed a
speed of 30 mph (50 km/h) while
driving with mounted snow chains.
It is not possible to mount snow
chains on tires with 17-inch
wheels.<

Brake fluid
The warning lamp for the brake
system's hydraulic circuits
comes on/the message
"CHECK BRAKE FLUID"
appears in the Check Control:
brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and cor-
recting the cause of brake fluid loss,
consult your BMW center. Your BMW
center is familiar with the specifications
for factory-approved brake fluids
(DOT 4).
Brake fluid loss may result in extended
brake pedal travel. Should this occur,
refer to the notes on page 134.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have
the brake fluid changed every two years
by a BMW center. Refer also to the Ser-
vice and Warranty Information Booklet
(US models) or to the Warranty and
Service Guide Booklet (Canadian
models).
Brake fluid is hazardous to health and
damages the vehicle's paint. You
should always store it in its original
container and in a location which is out
of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the MAX
mark. 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.<
