when you select the AUTO program.
Temperature adjustment
You can turn to select the
desired temperatures for the
driver and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains
this temperature, regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection
represented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic
air supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and
starts to provide maximum air supply
through the vent outlets only. For this rea-
son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/
recirculated air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-
air mode: the supply of outside air into
the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<

Things to remember when driving
Break-in procedures
To ensure that your vehicle continues to
furnish optimized economy of operation
throughout an extended service life, we
request that you devote careful attention
to the following section.
Engine and differential
Up to 1,200 miles/2,000 km:
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4,500 rpm or 105 mph/170 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine or vehicle speeds
can be gradually increased.
You should also comply with these break-in
procedures should the engine or differen-
tial need to be replaced at a later point.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period.Therefore, drive reservedly
during the first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve opti-
mized contact and wear patterns between
brake pads and rotors.
General driving notes
High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, and
never apply undercoating to them.
When driving, standing at idle and while
parking 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, accompanied by the risk of serious
property damage as well as personal
injury.<
Parking the vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into the car wash
1.Fold in the exterior mirrors, refer to
page 51, as otherwise they could be
damaged due to the width of the vehicle
2.Leave the remote control in the ignition
lock, as otherwise the position P of the
automatic transmission will automati-
cally be selected when the remote con-
trol is removed, refer to pages 61
and 67.
With Comfort Access, be sure to
observe the instructions on page 61
3.Release the parking brake, especially
when you have activated Automatic
Hold, refer to pages 62 and 63.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface. This phenomenon is referred

to as hydroplaning, and is characterized
by a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability to steer and brake
the vehicle.<
Driving through water
Do not drive through water on the
road if it is deeper than 1 ft/30 cm,
and then only at walking speed at the most.
Otherwise, the vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Brake system
Braking with ABS
The best way to achieve the best response
from the ABS is to apply maximum pres-
sure to the brake pedal Ð panic stop. Since
the vehicle maintains steering responsive-
ness, you can nevertheless avoid possible
obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Disc brakes
Driving in wet conditions
While driving in wet conditions and in
heavy rain, it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to ensure
that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to
ensure that full braking efficiency will then
be available when you need it.
Hills
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's
braking effect by selecting a lower gear
in the automatic transmission's manual
mode, downshifting as far as first gear
on extremely steep stretches, refer to
page 67. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never allow the vehicle to coast with
the transmission in Neutral Ð or with
the engine switched off Ð as there is no
engine braking when the transmission is in
Neutral, and no power-assist for brakes
and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are
less frequent, there is an increased ten-
dency for corrosion to form on rotors, while
contaminants accumulate on the brake
pads. This occurs because the minimal
pressure which must be exerted by the
pads during brake applications to clean the
rotors is not reached.
Should corrosion form on the brake rotors,
the brakes will tend to respond with a pul-
sating effect that even extended applica-
tion will fail to cure.
Brake pads
If the brake pad wear warning lamp
appears in the Check Control,
accompanied by a text. Please take
careful note of the additional information on
the Control Display.

Safety notes
A car phone can provide many services, in
an emergency even initiating a lifesaving
rescue. However, bear the following in
mind:
Adjustments
To avoid posing an unnecessary haz-
ard due to inattention, both to your
own vehicle's occupants and to other road
users: never attempt to use the controls or
make entries unless traffic and road condi-
tions allow.<
Using the phone in your vehicle
Using a portable phone to make and
receive calls while driving is now ille-
gal in virtually every country in the world.
Always use your hands-free system, or
stop your vehicle in an area where you will
not pose a safety hazard to other road
users and switch the engine off.<
Antenna
When using the phone, ensure that
all persons in the area are at least
20 in/50 cm from the antenna. Never use
your BMW portable phone if the antenna is
damaged. Contact between your skin and
a damaged antenna can result in minor
burns.
If the antenna is damaged, have it replaced
immediately.<
Special environmental conditions
Do not use your phone from within a
garage, or near an open hood. The air
in these areas could contain fuel vapors,
and the phone might generate sparks that
could result in burns.
This same precaution applies to opening
luggage compartment lids on vehicles
equipped for operation using natural gas or
hydrogen, and to all vehicles with luggage
compartment-mounted batteries.Always switch off your BMW portable
phone in areas where blasting work is
being conducted with explosives. The
phone signals could potentially act as a
high-frequency transmitter and set off
explosions.
Always switch off your BMW portable
phone in areas where an increased explo-
sion danger is present. This category
includes filling stations along with fuel and
chemical storage depots, etc., and all
areas in which the air can contain fuel,
chemicals or metal particles. Under these
conditions, your BMW portable phone
could conceivably generate sparks that
could lead to a fire or explosion. Always
observe all legal regulations governing the
use of portable phones in the vicinity of fill-
ing stations, chemical factories and other
areas where an explosion potential exists.
Never use the BMW portable phone in hos-
pitals, care centers or at other locations
where medical equipment may be in oper-
ation, such as accident sites, etc.
Your service provider can furnish you with
more detailed information on legal regula-
tions governing the use of your phone.<
Medical equipment
Portable phones can generate inter-
ference capable of preventing hearing
aids and cardiac pacemakers from operat-
ing correctly. If you or any occupant of the
vehicle will be using such equipment, con-
sult a physician or the manufacturer of the
equipment to determine whether it is ade-
quately shielded against high-frequency
energy.
Persons with cardiac pacemakers should
bear the following in mind:
Always hold the switched-on BMW porta-
ble phone more than 15 cm away from the
cardiac pacemaker.
Do not carry the BMW portable phone in
your breast pocket.
Use the ear on the opposite side of the car-
diac pacemaker to reduce the likelihood of

compartment
2.Take the button with the fuel pump
symbol from the bracket and pull it to
unlock the fuel filler door.
Always observe all applicable precau-
tions and regulations when handling
fuels. Never carry spare fuel containers in
your vehicle. Whether empty or full, these
containers can leak, cause an explosion,
and lead to fire in the event of a collision.<
Simple and environmentally friendly
When handling fuels always observe
any safety guidelines posted at the
filling station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
nozzle during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the
fuel-vapor recovery system.
The fuel tank is full when the filler nozzle
clicks off the first time.
Close the filler cap carefully after refu-
eling, continuing until you hear the
detent engage. While closing, be sure not
to squeeze the strap which is fastened to
the cap. A loose or missing cap will activate
a message in the Check Control.<
