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.
Do not leave the engine running in
enclosed spaces. Otherwise, inhalation of
the hazardous exhaust gases could lead to
unconsciousness and death. The exhaust
gases contain carbon monoxide, an odorless
and colorless, but highly toxic gas. Do not leave
the vehicle unattended with the engine running.
An unattended vehicle with a running engine
poses a safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the park-
ing brake to prevent the car from moving.<

Air distribution
Direct the flow of air to the windows
, to the upper body area and to
the footwell . Intermediate settings
are possible.
Switching cooling function on/off
When the cooling function is on, the
air is cooled, dehumidified, then
reheated depending on the tempera-
ture setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, temporarily shut off the supply
to the interior of the car. The system
recirculates the air within the vehicle.
If the windows fog over in the recircu-
lated-air mode, you should switch it off
and, if necessary, increase the air flow rate.
The manually controlled recirculated-air mode
should not be used continuously for lengthy
periods, otherwise the quality of the air inside
the car will gradually deteriorate.<
Temperature
For a higher temperature, turn the
rotary switch clockwise towards red.
For a lower temperature, turn the
rotary switch counterclockwise
towards blue.
Air flow rate
Adjust the air flow rate. The higher
the rate, the more effective the heat-
ing or cooling will be.
Switching the system on/off
Set the air flow rate to 0. Blower and air condi-
tioning are switched off and the air supply is cut
off.
To switch on the heater or air conditioning, set
any desired air flow rate.
Rear window defroster
The defroster switches off automati-
cally after a certain time.

Switch on the desired operating
mode by pressing this button repeat-
edly:
>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 inflow of outside air is shut off perma-
nently. The system recirculates the air
within the vehicle.
If the windows fog over in the recircu-
lated-air mode, you should switch it off
and, if necessary, increase the air flow rate.
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.<

Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter during reg-
ular maintenance. A substantial reduction in air
flow indicates that the filter needs to be
replaced earlier.

cannot be ruled out that vehicle electronics and
the mobile communications device interfere
with one another. In addition, it is not ensured
that the radio waves emitted during transmis-
sion are directed outside of the vehicle inte-
rior.<
Hydroplaning
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the tires and
the road surface. This situation, known as
hydroplaning, means that the tire can com-
pletely lose contact with the road surface, so
that neither the car can be steered nor the brake
be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page87.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Moisture inside the vehicle
Make sure that the passenger compart-
ment does not become wet and that liq-
uids are transported in closed containers.
Otherwise, moisture could penetrate and dam-
age electronic components inside the vehicle.<
Use the parking brake on inclines
On inclines, keep the vehicle from rolling
by using the parking brake rather than by
slipping the clutch, which would lead to a high
degree of clutch wear.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid possible obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Wet roads
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Watch traffic conditions to
ensure that this maneuver does not endanger
other road users. The resulting heat dries the
brake rotors and brake pads. Immediate braking
force is then available if necessary.
Inclines
To prevent overheating and, as a result,
diminished braking effectiveness, drive
down long or steep downhill grades in the gear
that requires the least braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page43.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on the brake rotors
Limited vehicle use, extended periods with the
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle,
low-pressure applications will all increase the
tendency for corrosion to form on the rotors and
contamination to accumulate on the brake
pads. This occurs because the minimal pres-

Correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, other-
wise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.<
You can inquire about the correct wheel/tire
combination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, only use tires of a single brand and
tread configuration. After a tire has been dam-
aged, for instance, mount the original wheel and
tire combination again as soon as possible.
Wheels with electronics for the Tire
Pressure Monitor TPM
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPMS electronics; otherwise the
Tire Pressure Monitor would not be able to
detect a flat tire, refer to page54. Your BMW
center will be glad to provide you with more
information.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW 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
generally do not achieve the full performance of
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pressure
indicated on the sidewall of the tire.
Swapping wheels between the axles
BMW advises against moving the front wheels
to the rear wheel positions and vice versa, as
this may impair vehicle handling characteristics.
