What the system can do
You can learn about the entire array of features
that Vehicle Memory and Key Memory offer you
at your BMW center. A few examples follow
below:
Examples for Vehicle Memory:
>Various signals as acknowledgement when
locking or unlocking your vehicle: refer to
page17
>Windows are opened automatically, refer to
page20
>Reminder that the key is still in the ignition
switch after the driver's door has been
opened, refer to page37
>Activation/deactivation of the Follow-me-
home function: refer to page56
>Activation/deactivation of daytime driving
lamps: refer to page56
>Sets the units of measure for displaying
time, outside temperature, distance trav-
eled and fuel consumption in the instru-
ment cluster, refer to page48.
Examples for Key Memory:
>Locking of the vehicle when you start off:
refer to page18
>Automatically adjusts the driver's seat to
the personal programmed settings when
the vehicle is unlocked, refer to page29.
You will see this symbol throughout the
Owner's Manual. It is to remind you at
appropriate places of the settings that are avail-
able to you.<
Depending on how the memory functions
are configured, the vehicle may be oper-
ated differently from what is described in the
Owner's Manual. Should you decide to sell your
BMW one day, please remember to have the
memory functions returned to their original fac-
tory settings.<

Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated manual gearbox with which clutch-
ing and shifting is assumed by an electro-
hydraulic system.
The SMG is operated via two shift paddles on
the steering wheel and the selector lever in the
center console.
It offers the following functions:
>Optionally manual or automatic operation:
sequential mode or drive mode
>Ability to choose between two different
driving programs: standard or Sport, refer to
page41
>Protection against misshifting, and auto-
matic downshifting at minimum engine rpm
even in sequential mode
>Kickdown function in the drive mode
>Acceleration assistant, refer to page42.
The SMG is ready for operation when the igni-
tion key is in position 2.
Selector lever positions
You can see the current selector lever position
in the center console.
>R: Reverse
>N: Neutral
>One-touch functions for the sequential
mode
+: manual upshifting
–: manual downshifting>D: Drive mode.
N is automatically selected if the driver's
door is opened while the engine is run-
ning and the driver does not actuate the pedals,
the shift paddles or the selector lever.
This is accompanied by an acoustic signal and a
flashing N in the instrument cluster.<

Sequential mode
Each time the engine is started, the sequential
mode is activated as soon as you move the
selector lever towards the right while depress-
ing the brake pedal.
The gear is changed via the shift paddles or the
selector lever.
It is also possible to drive off in second gear, e.g.
on slippery roads.
D Drive mode
In the drive mode all forward gears are shifted
automatically.
To switch from sequential to drive mode: tap
the selector lever to the right toward D.

Brake force display
The Brake force display lights up in two stages
depending on how strongly you are braking.
>Normal braking:
The brake lamps and the center brake lamp
light up
>Hard braking or braking with ABS:
In addition, the illuminated surface of the
brake lamps is extended, refer to the pic-
ture.
Flat Tire Monitor
The concept
As you drive, the Flat Tire Monitor keeps track
of pressure levels in all four tires. The system
alerts you whenever the inflation pressure of a
tire falls significantly below the pressure of
another tire.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affecting the
rotational speed of the wheels. This change is
detected, and a flat tire warning is issued to the
driver.
System requirements
To ensure a reliable flat tire warning, the system
must be initialized with the correct tire inflation
pressures.
Each time you correct the pressure in a
tire, or change a wheel or tire, the system
must be re-initialized.<
System limitations
The Flat Tire Monitor cannot provide you
with advance warning of sudden and
severe tire damage caused by external factors
and does not detect the balanced and very
gradual pressure loss that takes place in all four
tires over an extended period of time.<
The system could issue a false warning or func-
tion in a delayed manner in the following situa-
tions:
>System was not initialized
>You are driving on a snow-covered or slip-
pery road surface
>Performance-oriented driving: slip at the
drive wheels, high levels of lateral accelera-
tion
>You are driving with snow chains.
Initializing the system
The initialization is completed while you
are driving, and can be interrupted at any
time. Initialization is automatically continued
when you continue driving.
When driving with snow chains, do not initialize
the system.<
1.Start the engine, but do not drive off
2.Press the button as long as you need to until
the yellow indicator lamp in the instrument
cluster lights up for a few seconds
3.Drive off.
Initialization is completed during the drive,
without any feedback issued.

Lamps

Lamps
Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle lighting
is switched on. You can use the parking
lamps to signal the position of the vehi-
cle when it is parked. For information on lighting
on one side of the vehicle for parking, which is
available as an additional feature, refer to
page57.
Low beams
When you switch off the ignition with
the low beam headlamps on, only the
parking lamps will remain on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page91.
Follow me home lamps
When you activate the headlamp flasher after
parking the vehicle and switching off the lights,
the low beams will come on for a brief period.
You can also have this function activated/
deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after hav-
ing turned the ignition key to position 0, you will
hear an acoustic signal for a few seconds to remind you that the lamps have not been
switched off.
Daytime driving lamps*
If you desire, the light switch can be left in the
second position:
When the ignition is switched off, the external
lighting is also switched off.
You can have the activation settings for
the daytime driving lamps programmed
on your vehicle.<
Automatic headlamp control*
When the switch is set to this position,
the system automatically activates and
cancels the low beams in response to
changes in ambient light, for example in tun-
nels, at dusk, and when it is raining or snowing.
The low-beam headlamps remain on
regardless of the ambient light when you
switch on the fog lamps.<
Automatic headlamp control cannot
serve as a substitute for the driver's jud-
gement in determining when the vehicle lights
should be switched on. For example, the sen-
sors 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 manually.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<

Controlling the climate for pleasant driving
62
Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior tem-
perature.
Detailed setting options are described for you
below.
Automatic air distribution and supply
The AUTO program assumes the
adjustment of the air distribution and
air supply for you and in addition
adapts the temperature to external
influences, summer or winter, to meet prefer-
ences you can specify.
In the AUTO program, the air conditioning
mode is also turned on at the same time.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Individual air distribution
You yourself can direct airflow onto
the windows , toward the upper
body and into the footwell . The
arrow lights up. The automatic air
supply remains unchanged. All intermediate
settings are possible. By pressing the AUTO
button, you can reactivate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a gen-
eral figure intended for reference
purposes. When you start the vehi-
cle, the system ensures that the selected tem-
perature is reached as quickly as possible,
regardless of the season. It then maintains this
temperature.
Air supply/blower
Turn the rotary control to adjust the
air supply. This shuts off the auto-
matic air supply. The arrow lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic air supply by pressing the AUTO but-
ton.When you turn the rotary control toward zero:
the blower, heating and air conditioner are
switched off, and the air supply is stopped. You
can reactivate the system by turning the control
toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
Above an outside temperature of
327/06 and with the engine run-
ning, you achieve a maximum cooling
effect as quickly as possible. At the
same time, the air conditioning is turned on.
The temperature is set to the lowest possible
value. The system switches to the recirculated
air mode, and air flows at maximum blower
speed from the ventilation grills in the upper
body area only. Therefore, the air outlets must
always be open when you select this program.
Air conditioning
The air is cooled and dehumidified
and, depending on the temperature
setting, rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the engine is
started.
The air conditioning system is automatically
switched on when you use the AUTO program.
Condensation forms during operation of
the air conditioning system, which then
exits under the vehicle. Traces of condensed
water on the ground underneath the vehicle are
thus normal.<
Outside air/Automatic recirculated air
control AUC/recirculated air mode
You can respond to unpleasant
external odors or pollutants by tem-
porarily stopping the flow of outside
air. The system then recirculates the
air currently within the vehicle.

Maintenance
The BMW Maintenance
System
The BMW Maintenance System helps maintain
the road safety and operating reliability of your
BMW.
Please keep in mind that regular maintenance is
not only necessary for the safety of your vehi-
cle, but also plays a significant role in maintain-
ing the resale value of your vehicle.
Service interval display
While conventional systems rely on distance
traveled alone to determine when a service is
due, the BMW Maintenance System has taken
the actual conditions under which the vehicle is
operated into consideration for years, because
miles can be traveled in many different ways:
From a maintenance point of view,
60,000 miles/100,000 km accumulated in
short-distance urban driving are not the same
as 60,000 miles/100,000 km accumulated at
moderate cruising speeds in long-distance
highway travel.
The BMW Maintenance System includes the
Engine Oil Service and Inspections I and II.
Determining the maintenance intervals based
on the actual loads on the vehicle covers every
kind of operating situation. Minimal use drivers,
who drive fewer than about 6,200 miles/
10,000 km per year, should nevertheless have
the oil changed at least every 2 years since
engine oil deteriorates over time, regardless of
use.

Service Guide Booklet for Canadian
models
For additional information on required mainte-
nance intervals and procedures, please refer to
the Service and Warranty Information Booklet
for US models, or the Warranty and Service
Guide Booklet for Canadian models.
Depending on operating conditions, it may be
advisable to have the body checked for damage
from rocks or gravel as a precaution against cor-
rosion.
BMW recommends that you have your
BMW center perform the maintenance
and repair.
Be sure that all maintenance work is recorded in
the Service and Warranty Information Booklet
for US models, Warranty and Service Guide
Booklet for Canadian models. These entries will
serve as proof that the vehicle has received reg-
ular maintenance.<
