spare key into the adapter before using it.
Personal Profile
The concept
You can set many of your BMW's functions to
suit your personal needs and preferences.
Without any action on your part, Personal Pro-
file ensures that most of these settings are
stored for the remote control currently in use.
When you unlock the car, the remote control
used for the purpose is recognized and the set-
tings stored for it are called up and imple-
mented.
This means that your personal settings are
active when you return to your BMW, even if the
car was used in the meantime by someone else
with a remote control of their own and the set-
tings were changed accordingly.
You can configure a maximum of three remote
controls for three different people. The prereq-
uisite for this is that each person has his or her
own remote control.
Personal Profile settings
For more information on specific settings, refer
to the specified pages.

Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
>Tailgate
>Fuel filler door
Operating from outside
>Via the remote control
>Via the door lock
>In cars with convenient access
*, via the
handles on the driver's and front passen-
ger's doors
The anti-theft system is also operated at the
same time. It prevents the doors from being
unlocked using the lock buttons or door han-
dles. The interior lamp and the courtesy lamps
*
are also switched on or off with the remote con-
trol. The alarm system
* is also armed or dis-
armed.
For further details of the alarm system,
refer to
page25.
Operating from inside
By means of the button for central locking, refer
to page22.

Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance if it has become
too hot in the car.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and not straight at you.
Microfilter
The microfilter removes dust and pollen from
the incoming air. The microfilter is changed by
your BMW Center during routine maintenance work. You can call up further information in the
service requirements display, refer to page61.

Comfortable interior climate
AUTO program4 offers the ideal air distribution
and air flow rate for almost all conditions, refer
to AUTO program below. All you need to do is
select an interior temperature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer also to Personal Profile
settings on page19.
Switching manual air distribution on/
off
The emerging air is directed to the
windows, to the upper body area or
to the footwell.
You can switch the automatic air
distribution back on by pressing the AUTO but-
ton.
Temperature
Set the desired temperatures indi-
vidually for the driver's and front
passenger's sides.
The automatic climate control
achieves this temperature as quickly as possi-
ble regardless of the season, using maximum
cooling or heating power if necessary, and then
maintains it.
When you switch between different tem-
perature settings in quick succession, the
automatic climate control does not have
enough time to achieve the set temperature.<
Maximum cooling
At outside temperatures above
327/06 and when the engine is
running, you obtain a maximum
cooling effect as soon as possible.
The automatic climate control switches to the
lowest temperature and operates in recircu-
lated-air mode. Air flows at maximum rate only
from the vents for the upper body area. You

Climate
82 should therefore open them for maximum cool-
ing.
AUTO program
The AUTO program adjusts the air
distribution to the windshield and
side windows, towards the upper
body area and into the footwell for you. The air
flow rate and your temperature specifications
will be adapted to outside influences as a result
of seasonal changes, e.g. sunlight or window
condensation.
The cooling is switched on automatically with
the AUTO program.
Adjusting air flow rate manually
Press the left side of the button to
reduce airflow. Press the right side
of the button to increase it.
You can reactivate the automatic mode for the
air flow rate with the AUTO button.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All indicators go out.
Press any button except REST to reactivate the
automatic climate control.
AUC Automatic recirculated-air
control/Recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
>LEDs off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently shut off. The system then recirculates the
air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<
Via the button* on the steering wheel
You can switch between operating modes via a
button
on the steering wheel, refer to page11:
>When outside air is coming in, you can use
the button on the steering wheel to switch
between outside air and recirculated-air
mode.
>When recirculated-air mode or AUC mode
is switched on, you can use the button on
the steering wheel to switch between recir-
culated-air mode and AUC mode.
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.

Things to remember when driving
96
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100 mph or 160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
After 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Close the tailgate
Operate the vehicle only when the tail-
gate and rear window are closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If special circumstances make it absolutely nec-
essary to drive with the tailgate or rear window
open:
1.Close all windows and the glass sunroof.
2.Increase the air flow rate of the air condi-
tioner or automatic climate control consid-
erably, refer to page79 or82.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, with the
risk of serious personal injuries and property
damage.<
Mobile phone in the vehicle
BMW discourages the use of mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,

Wheels and tires

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transport.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 0705 means that the
tire was manufactured in week 7 of 2005.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air. The
objective is to optimize efforts with respect to
minimal vehicle maintenance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
In the instrument cluster, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page61:
>Engine oil
>Brakes: separately for front and rear
>Microfilter/activated-charcoal filter
for auto-
matic climate control
>Microfilter
for air conditioner
>Brake fluid>Spark plugs
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date in the instrument
cluster is always set correctly, refer to
page63; otherwise the effectiveness of Condi-
tion Based Service CBS is not assured.<
