Vehicle Memory, Key Memory How 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
adjustment data for as many as four
different individuals into the system.
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.
Color-coded decals have been
provided to help you distinguish indi-
vidual keys with different settings.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, refer to pages 29, 31
>Activates/deactivates the "Follow me
home" function, refer to page 82
>Activates/deactivates daytime driving
lamps, refer to page 82.Examples for Key Memory:
>Locks the vehicle when you start off,
refer to page 32
>Automatically adjusts the power seat
to your personal programmed
settings when you unlock the vehicle,
refer to page 46
>Unlocks driver's door first, then
proceeds to disengage the vehicle's
remaining locks, refer to page 29.
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.<

Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position "P" until the engine is running
(ignition key position 2).
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 and removed
until the selector lever is in
position "P."<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the
steering wheel slightly to the left or right
until you hear the lock engage.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition (ignition key in position 0
or key extracted). Simply switch it back
on.Steering unlocked You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation.
Before starting>Engage the parking brake
>Ensure that the shift lever is in
neutral, or, with an automatic trans-
mission, that the selector lever is in
position "P"
>Depress the clutch pedal.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas.
Breathing the exhaust gases poses an
extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious
personal injury and property damage.<
>Start the engine. Do not press the
accelerator pedal.

Starting the engine Switching off the engine
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, drive off
immediately at a moderate engine
speed.<
If the engine does not start on the first
attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures of roughly +5 7 (Ð15 6) or below
and at altitudes of over 3,300 ft
(1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging,
always deactivate electrical devices
that are not in use. Switch the ignition
off when the vehicle is not being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to catalyst
damage.<
Turn the ignition key to position 1 or 0.
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on hills and slopes, as first gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<

Automatic transmission with Steptronic
*
You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by "+" or "Ð." Whenever you want to use
the automatic transmission mode again,
move the selector lever to the right into
the "D" position.
Range selection
P R N D M/S + Ð
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts to
the "Reverse" or "Park" selector lever
positions. To disengage the detent,
press the button on the front side of
the shift knob (arrow).
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. The vehicle will otherwise "creep"
when a drive position is engaged.<
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 unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
P ParkSelect only when the vehicle is
stationary. Transmission locks to
prevent rear wheels from turning.R ReverseSelect only when the vehicle is
stationary.

Automatic transmission with Steptronic
*
N NeutralSelect only when stopping for an
extended period.D Drive (automatic shift program)This position is designed for driving
under all normal operating conditions.
All forward gears are available.KickdownIn the kickdown mode, you achieve
maximum acceleration and in
position D top speed.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S Manual mode and
Sport ProgramMove the selector lever from D to M/S
to activate the Sport Program; SD
appears in the display panel. The M/S
mode is recommended for perfor-
mance-oriented driving.
Once in the M/S mode you can tap the
selector lever to switch the automatic
transmission from the Sport Program to
its manual selection mode.
This mode allows you to execute
upshifts manually by tapping the lever
toward "+," while downshifts are
selected by tapping in the "Ð" direction.
The displays M1 through M5 appear in
the display panel to indicate your
current gear selection.
The Adaptive Transmission Control
(ATC) executes upshifts and downshifts
only when the new gear will provide a
suitable combination of engine and
road speed, for example ATC will not
execute downshifts if the engine speed
to too high. The desired, then the actual
gear, briefly appear in the instrument
cluster.
To accelerate quickly in the
manual mode (to pass another
vehicle), shift down manually or employ
the kickdown mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.

performance has been restored. You
may continue to drive as usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only operate in 3rd and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Never work in the engine
compartment when a drive gear
(forward or reverse) is engaged. If you
do this, the vehicle could move.<
For towing or jump-starting, refer to the
information beginning on page 134.

Cruise control
*
You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
The cruise control is available whenever
the engine is running and the system
has been activated.
To activate the systemIn ignition key position 2:
Press the button and the indicator lamp
on the instrument cluster will come on,
refer to page 20. You can now use the
cruise control.
Do not use cruise control on
twisting roads, when high traffic
density prevents driving at a constant
speed, or when the road surface is slick
(snow, rain, ice) or loose (rocks or
gravel, sand).<To deactivate the systemPress button as often as needed until
the indicator lamp in the instrument
cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.
To store and maintain speed
or to acceleratePress button (+) briefly:
The system registers and maintains the
current vehicle speed. Every time you
tap the button, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold button (+):
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
registers and maintains the current
speed.
If, on a downhill gradient, the
engine braking effect is not suffi-
cient, the preset speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<

Fuel gauge Temperature gauge Service Interval DisplayOnce the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For information on the fuel tank
capacity, refer to page 143.
Certain operating conditions (such as
those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Shut off the engine immediately
and allow it to cool down.
For instructions on checking the
coolant level, refer to page 117.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance to serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OIL SERVICE or INSPEC-
TION, together with the distance
remaining in miles (kilometers) before
the next scheduled service. The
computer bases its calculations of the
remaining distance on the preceding
driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.
