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.<

Automatic transmission
*
Before leaving the vehicle when
the engine is running, move the
selector lever to the "Park" or "Neutral"
position and apply the parking brake to
prevent the vehicle from rolling.
Never leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.
If you should accidentally select
"Neutral" while traveling at high speed,
remove your foot from the accelerator
pedal immediately. Allow the engine
speed to drop to idle before selecting
the desired drive position. Damage
could otherwise occur due to excessive
engine speed.<
P ParkSelect only when the vehicle is com-
pletely stopped. The transmission locks
to prevent the rear wheels from turning.R ReverseSelect only when the vehicle is com-
pletely stopped.
N Neutral (idle)Select only if your journey is interrupted
for a longer period.D Drive
(automatic shift program)This position is designed for driving
under all normal operating conditions.
All forward gears are available.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.4 Ð Sport ProgramThe Sport Program is designed for per-
formance-oriented driving.
3 and 2 Ð shift limiterSelect this range when you wish to limit
gear changes (on steep uphill or down-
hill slopes, for instance). The transmis-
sion shifts up only as far as the selected
gear limit."Kickdown" In the "kickdown" mode, you achieve
maximum performance.
Depress the accelerator pedal past the
resistance point at the full-throttle posi-
tion.

Automatic transmission with Steptronic
*
To prevent the vehicle from
starting off on its own, always
move the selector lever to position P or
N and engage the parking brake before
leaving your vehicle with the engine
running. Do not leave the vehicle unat-
tended with the engine running. An
unattended vehicle with a running
engine represents a potential safety
hazard.<
P ParkSelect "Park" only when the vehicle is
completely stopped. The transmission
locks to prevent the rear wheels from
turning.R ReverseSelect "Reverse" only when the vehicle
is completely stopped.N Neutral (idle)Select "Neutral" only if your journey is
interrupted for a longer period.
D Drive
(automatic shift program)This position is designed for driving
under all normal operating conditions.
All forward gears are available."Kickdown"In the "kickdown" mode, you achieve
maximum acceleration and top speed
in position D.
Depress the accelerator pedal past the
resistance point at the full-throttle posi-
tion.
M/S Manual mode and
Sport ProgramWhen you change from "D" to "M/S,"
the Sport Program is activated. This is
indicated by "D S" in the transmission
range display. The Sport Program is
designed for performance-oriented
driving.
With the first brief touch, the automatic
transmission shifts from the Sport Pro-
gram to the manual mode. Whenever
you move the selector lever in the "+"
direction, the transmission upshifts, and
when you move it in the "Ð" direction,
the transmission downshifts. M1...M5
will be displayed in the gear indicator.390de721

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.

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.<

Lamps and bulbs Changing a wheelLicense plate lamps5 watt bulb
1. Insert a screwdriver into the slot and
press to the left (arrow); this disen-
gages the lamp
2. Remove the lamp and replace the
bulb.394de772
Safety measures in the event of a
flat tire or wheel change:
Stop the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. Switch on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse (selector lever in Park with
automatic transmission) and engage
the parking brake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area (behind a guardrail,
for instance).
If necessary, set up your warning tri-
angle or portable hazard warning lamp
on the roadside at an appropriate dis-
tance from the rear of the vehicle.
Comply with all safety guidelines and
regulations.
Change the wheel only on a level, firm
surface which is not slippery. Avoid
jacking the vehicle up on a soft or slip-
pery surface (snow, ice, very smooth
surfaces, etc.), since it could slide side-
ways.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack Ð risk of fatal injury.<
