Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. The AUTO program adjusts the
air supply and the air distribu-
tion to the windshield and the side win-
dows, towards the upper body and to
the footwells, and in addition adapts
the temperature to external influences:
e.g. summer, winter.
The cooling function is automatically
switched on when you are using the
AUTO program.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air distri-
bution mode by selecting the AUTO
button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence purposes. We recommend 727/
+226 as a comfortable setting, even if
the air conditioning is on. When you
start the vehicle, the system ensures
that the selected temperature is
achieved as quickly as possible. It then
maintains this temperature, regardless
of the season.
To select the units of measure 7/6 of
the display, refer to page 88.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic control of the air supply, AUTO
disappears from the display panel. Nev-
ertheless, the automatic air distribution
remains unchanged. You can reactivate
the automatic air distribution mode by
selecting the AUTO button.
When the lowest blower speed is set
and you press the lower button, all of
the displays are canceled: the blower,
heating and air conditioning are
switched off. The outside air supply is
blocked. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
The cooling function is automatically
switched on when you are using the
AUTO program.

Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle. It is
thus not unusual for a small puddle to
form under the car while the system is
running.<
Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
>Indicator lamps off: outside airflow is
on
>Left indicator lamp on – automatic
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The sys-
tem then recirculates the air currently
within the vehicle. Depending on the
air quality, the automatic system then
switches back and forth between
outside air supply and recirculation of
the air within the vehicle
>Right indicator lamp on: the flow of
outside air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
this mode off and increase the air sup-
ply as required. With the convertible top closed
or with the hardtop* mounted,
press the button. The indicator lamp
comes on. The rear window defroster
switches off automatically after a short
while.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vent out-
lets
2Levers for airflow direction
3With the rotary dial, you can add
more or less cool air to the air coming
from the outlets for the upper body
area:
>Rotate toward blue – colder
>Turn toward red – warmer.

Cargo loading
Avoid overloading the vehicle so
that the permitted load on the tires
is not exceeded. Overloading can lead
to overheating and internal tire damage.
The ultimate result can assume the
form of a sudden air loss.<
Determining the maximum load1. Locate the following statement on
your vehicle‘s placard*:
The combined weight of occu-
pants and cargo should never
exceed XXX kg or YYY lbs., as this
could otherwise result in damage to the
vehicle or unstable driving conditions.<
2. Determine the combined weight of
the driver and passengers that will be
riding in your vehicle
3. Subtract the combined weight of the
driver and passengers from
XXX kilograms or YYY pounds
4. The resulting figure equals the avail-
able amount of cargo and luggage
load capacity.
For example, if the XXX amount
equals 1,400 lbs. and there will be
five 150 lbs. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4
6. If your vehicle will be towing a trailer,
load from your trailer will be trans-
fered to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.

Inclines:
To prevent overheating and, as a
result, diminished braking effec-
tiveness, drive down long or steep
downhill grades in a gear which
requires the least braking. Otherwise,
even light but consistent pedal pres-
sure can lead to high temperatures,
brake wear and possibly even brake
failure.<
The braking power of the engine can be
further enhanced by downshifting the
automatic transmission in manual
mode, if necessary, into first gear. This
helps avoid placing excessive loads on
the brake system.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in Neutral. Do not
coast with the engine switched off. Oth-
erwise, the engine provides no braking
effect while the transmission is in idling
position, and there is no power-assist
for braking or steering when the engine
is off.
Floor mats, floor carpets or other
objects must not be in the area near the
brake or accelerator pedal, as this
could impair the movement of the ped-
als.<
Corrosion on the brake rotorsLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which brak-
ing is restricted to gentle, low-pressure
applications will all increase the ten-
dency for corrosion to form on the
rotors and contamination to accumulate
on the brake pads. This occurs because
the minimal pressure which must be
exerted by the pads to clean the rotors
by brake applications is not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Portable phone in the vehicle
BMW advises against using
mobile equipment, e.g. cellular
phones, inside the vehicle without con-
necting them directly to an outside
antenna. Otherwise, it cannot be ruled
out that vehicle electronics and the
mobile equipment interfere with one
another. In addition, it is not ensured
that the radio waves emitted during
transmission are directed outside of the
vehicle interior.<
General driving notes

Tire treadTread depth should not be allowed to
go below 1/8 in/3 mm, even though
European legislation, for example,
requires a mimimum tread depth of only
1/16 in/1.6 mm. Below 1/8 in/3 mm
tread depth, there is a great risk of
hydroplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.
At tread depths below approx.
3/16 in/4 mm, tire performance under
winter driving conditions deteriorates
noticeably. Worn tires should therefore
be replaced for safety considerations.
Tread wear indicators in the tread-
groove base, see arrow, are distributed
around the wheel circumference and
are labeled on the tire sidewall with
TWI, Tread Wear Indicator. At a tread
depth of 1/16 in/1.6 mm, the indicators
signal that the legally permissible wear
limit has been reached.
Run Flat tires*Run Flat tires are labeled on the side-
wall with a circular symbol containing
the letters RSC.
Run Flat tires consist of self-supporting
tires and special rims. The tire rein-
forcement ensures that driving remains
possible to a restricted degree in the
event of pressure drop or even if the tire
is deflated.Driving with a damaged tireDepending on the cargo load, Run Flat
tires allow you to continue driving at a
maximum speed of 50 mph / 80 km/h.

tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Run Flat tiresIf your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, use only
these tires since no spare wheel is
available in the event of a flat.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.
Run Flat tires:
If your vehicle is equipped with Run Flat
tires, refer to Run Flat tires, please note
the following: when mounting new tires
or replacing summer tires with winter tires, or vice versa, use only Run Flat
tires since no spare wheel is available
in the event of a flat. Your BMW center
wil be glad to advise you.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.
Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult your
BMW center for details. BMW recom-
mends using only these approved fine-
link snow chains. Use them in pairs on
either summer or winter tires, but only
on both rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
You cannot mount snow chains with the
following tires:
>225/50 R 16
>225/45 R 17
>245/40 R 17
>225/40 R 18
>255/35 R 18.
Do not initialize the Flat Tire Moni-
tor after mounting snow chains to
the tires.
When driving with snow chains, it may
be useful to turn off the DSC for a short
time, refer to page 92.<

Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Store oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Recommendation: have the oil changed
at your BMW center.Specified engine oilsThe quality of the engine oil is
extremely important for the operation
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small amounts of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit
this website: www.bmwusa.com to
obtain this information.Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for driv-
ing in all ambient temperatures.

146Maintenance
BMW Maintenance SystemThe BMW Maintenance System helps
maintain your vehicle's road safety and
operational safety. Comfort-related
aspects, such as the timely change of
filters for the air inside the vehicle, are
taken into consideration. The goal is to
optimize maintenance with respect to
low total cost of ownership.
If you should sell your BMW one day,
consistent service and maintenance will
prove to your advantage.
Service interval displayThe service interval display shows you
when an oil service, an inspection –
always alternating between I and II – or
a brake fluid change is due. The special
feature is that the service intervals are
calculated according to your BMW's
individual driving conditions instead of
from fixed mileage increments.
The technology developed for this
takes your personal driving style into
account, as well as your BMW's driving
conditions. After all, short-distance
driving, i.e. frequent cold starts, or driv-
ing off at high engine speeds, affects
your BMW differently from long-dis-
tance driving with the engine at consis-
tent operating temperature.
Special feature regarding engine
oil changeThe calculation of the service intervals
covers practically every kind of operat-
ing situation. If you drive very rarely,
however, you should have the oil
changed at least every two years, since
engine oil deteriorates over time
regardless of use.Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.
As a precaution against corrosion, if
your vehicle is exposed to potential
damage from unimproved road sur-
faces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.

BatteryMaintenanceThe battery is completely maintenance-
free. This means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions. Your BMW center
will be glad to advise you if you have
any questions concerning the battery.
Please consult your BMW center
whenever you have any questions
concerning the battery. cle, leave the engine off at all times.
Connect the charge cables to the termi-
nals in the engine compartment. For
terminal locations, refer to Jump-start-
ing on page 163.Disposal
After changing the battery, have
the old battery disposed of by
your BMW center or bring it to a recy-
cling point. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting
during transport.<
Power lossAfter a temporary power loss, e.g. due
to a discharged battery, some equip-
ment will be limited in its use and will
have to be reinitialized. Individual set-
tings are also lost and must be reset:
>Seat and mirror memory
The position settings must be stored
again, refer to page 55
>Clock
must be reset, refer to page 87
>Radio
Stations must be reset, refer to the
Owner's Manual for Radio/Onboard
Computer
>Navigation system
The system will not be operable
immediately, refer to the Owner's
Manual for Radio/Onboard Com-
puter.
FusesYou will find the fuses and information
on their respective allocation in the
glove compartment behind a panel with
two snap clips.
Do not attempt to repair a blown
fuse or replace it with a fuse
having a different color or amperage
rating. To do this could cause a fire in
the vehicle resulting from a circuit over-
load.<
