Air volume
You can vary the air volume in
steps 1 through 4. The heating or
cooling output is more effective
with a higher air volume.
Switching system on/off
Turn air volume rotary switch to 0. This com-
pletely shuts off the blower and air conditioning
system and stops the flow of air.
To switch on the air conditioning system, set an
arbitrary air volume.
Temperature
To increase the temperature, turn
to the right, toward red.
For a lower temperature, turn the
rotary switch counterclockwise
toward blue.
Air distribution
You can direct air to flow onto the
windows , toward the upper
body and into the footwell .
Intermediate settings are possible.
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.
Switching cooling function on/off
When the cooling function is on,
the air is cooled, dehumidified, and
then reheated depending on the
temperature setting.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Recirculated-air mode
You can respond to unpleasant
odors outside the vehicle by tem-
porarily suspending the supply of
outside air. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in recirculated-air mode, you should switch it off
and increase the air supply 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.<

A congenial climate
For almost all conditions, the AUTO program 12
offers the optimum air distribution and air vol-
ume, 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. 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. It is only pos-
sible to cool the passenger compartment when
the engine is running.

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
1Knurled wheels for opening and closing the
air vents through an infinitely variable range
2Levers for changing airflow direction
3Knurled wheel for more or less cool air from
the air vents for the upper body region
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.

2.Greatly increase the air supply of the air
conditioning system or automatic climate
control, refer to page62 or65.
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.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. mobile
phones, on the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise, the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
When the 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 page32;
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 page41.
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 page94.
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 pads and rotors.
The full braking force will then be available
when you need it.

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages53,
54.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve optimum driving com-
fort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire’s resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a level of performance that all pas-
senger car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm. At tread depths below 0.12 in/3 mm,
there is an increased risk of high-speed hydro-
planing, even when only small amounts of water
are present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires, make
wheels, tires and suspension parts more
susceptible to road hazard and consequential
damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires checked
immediately. Drive carefully to the nearest
BMW Sports Activity Vehicle Center or tire spe-
cialist. Have the vehicle towed to one of these
locations if necessary.
Tire damage can pose a potentially lethal safety
hazard for the vehicle's occupants and other
road users alike.<
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-
