A congenial climate
For almost all conditions, the AUTO pro-
gram12 offers the optimum air distribution and
air volume, refer to AUTO program below. You
need only select an interior temperature 5 that
you find pleasant.
The following sections contain more detailed
information on the available setting options.
Your vehicle has been designed to auto-
matically select your personal climate-
control settings whenever you unlock the doors
using your individually programmed remote
control.<
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well. It also adapts your instructions for the air
volume and temperature to outside influences
throughout the year, e.g. solar radiation or win-
dow condensation.
The cooling function is switched on automati-
cally along with the AUTO program.
Manually switching air distribution
on/off
You can direct air to flow onto the
windows , toward the upper
body and into the footwell .
You can reactivate the automatic
air distribution mode by selecting
the AUTO button.
Temperature
Set the desired temperature.
The automatic climate control
assures that this temperature is
reached as quickly as possible any
time of year, using maximum cool-
ing or heating capacity as needed, and then
keeps this temperature constant.The highest setting produces the maximum
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air
conditioning.
When you change between different tem-
perature settings in rapid succession, the
system does not have enough time to achieve
the desired temperature.<
Manually adjusting air volume
By pressing the lower button, you
can reduce the air volume. You can
increase it by pressing the upper
button.
You can reactivate the automatic
air volume mode by pressing the AUTO button.
Switching system on/off
At the lowest fan speed, press the lower button
to turn off the automatic climate control com-
pletely. All displays disappear.
Press any button to turn the automatic climate
control back on again.
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front door windows.
Also switch on the cooling function.
Switching cooling function on/off
When the cooling function is on,
the air is cooled, dehumidified, and
then reheated depending on the
temperature setting. This function is only avail-
able with the engine running.
The cooling function helps to prevent conden-
sation from forming on the windows or to
remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is automatically switched
on along with the AUTO program.

AUC Automatic Recirculated-air
Control/recirculated air mode
You can set the desired operating
mode by pressing the button
repeatedly:
>LEDs off: outside air continuously flows into
the vehicle.
>Left LED on, AUC mode: a sensor detects
pollutants in the outside air. The system
suspends the supply of outside air as
needed and recirculates the air currently
within the vehicle. As soon as the concen-
tration of pollutants in the outside air has
decreased sufficiently, the system switches
automatically back to supplying outside air.
>Right LED on, recirculated-air mode: the
outside air supply into the vehicle is shut off
continuously. The system then recirculates
the air currently within the vehicle.
If the windows fog over in recirculated-air
mode, then press the AUTO button or
switch off the recirculated air mode and
increase the air volume as needed.
The recirculated-air mode should not be used
over a sustained period of time; otherwise, the
air quality inside the vehicle will steadily deteri-
orate.<
Rear window defroster
The rear window heating switches
off automatically after a certain
amount of time. Depending on
your equipment package, the upper wires are
used as an antenna and are not part of the rear
window defroster.
Ventilation
1Serrated dials for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Serrated dial for more or less cool air from
the air vents for the upper body region,
independent of the temperature selected
on the automatic climate control
Ventilation for cooling
Adjust the vents to direct the flow of cool air in
your direction, for instance, if the interior has
become too warm.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter*
The microfilter removes dust and pollen from
the incoming outside air. The activated-char-
coal filter provides additional protection by fil-
tering gaseous pollutants from the outside air.
This combined filter is replaced when mainte-
nance is performed by your BMW Sports Activ-
ity Vehicle Center. A substantial reduction in
air supply indicates that the filter should be
replaced before normal maintenance.

Things to remember when driving
84
General driving notes
Closing liftgate
Operate the vehicle only when the liftgate
is completely closed; otherwise, exhaust
fumes could enter the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
liftgate open:
1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioning system or automatic climate
control, refer to page64 or67.
Hot exhaust system
High temperatures occur in the exhaust
system of every vehicle. Do not remove
the heat shields installed adjacent to various
sections of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle, and 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, resulting in serious personal injury and
property damage. Do not touch hot exhaust
pipe, it can cause burns.<
When vehicle is parked
Condensation forms in the air conditioner/auto-
matic climate control system during operation,
and then exits under the vehicle. Traces of con-
densed water under the vehicle are therefore
normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page33;
otherwise, they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor; otherwise, damage
could result from undesired wiper activation,
refer to page42.
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 sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
The danger of hydroplaning increases as tire
tread depth decreases, also refer to Minimum
tread depth on page98.
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle´s
engine, the electrical systems and the trans-
mission may be damaged.<
Using handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise, greater clutch
wear will result.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake rotors and pads.
The full braking force will then be available
when you need it.

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 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 3008 indicates that a tire was manufac-
tured in week 30 of the year 2008.
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 (1 1/2) times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement, as measured under con-
trolled conditions on specified government test
surfaces 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.<
