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.

Engine oil
Engine oil consumption depends on driving
style and operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top off as needed. If the oil level is correct:
Have the system checked immediately.
Do not continue driving. The engine could
be damaged because of inadequate lubri-
cation.<
Engine oil level
The warning lamp lights up yellow dur-
ing driving. An acoustic signal also
sounds and "+1.0 " is displayed in the
instrument cluster, refer to page99.
The oil level is at its absolute minimum; top off
engine oil as soon as possible. Until then, do not
drive more than approx. 125 miles/200 km.
The warning lamp lights up yellow after
the engine is switched off. In addition, a
signal sounds.
Top off engine oil at the earliest opportunity,
e.g. with your next refueling.
The warning lamp lights up yellow
within 30 seconds after starting the
engine:
The oil level sensor has failed. It is not possible
to take a current or meaningful measurement.
Have the system checked as soon as possible.
Checking oil level
Your vehicle is equipped with an electronic oil
level control.
For the most precise possible display of the oil
level, the engine must be at operating tempera-
ture, i.e. after at least 6.5 miles/10 km of unin-
terrupted driving. You can have the oil level dis-
played while you drive or while the vehicle is standing on a flat surface with the engine run-
ning.
You can have the current oil level displayed in
the instrument cluster.
Press button1. The oil level is checked and dis-
played for approx. 15 seconds.
In order to cancel the display early, press but-
ton 1 again.
Possible displays
1Oil level OK
2Oil level is being detected
This process can last approx. 3 minutes
while standing on a flat surface and approx.
5 minutes while driving.

Under the hood
100 3Oil level at minimum
A t yo ur e a r li es t o p p ortunity, add 1 US quart/
1 liter engine oil, also refer to Adding engine
oil.
4Oil level too high
Have vehicle checked immediately;
otherwise, overfilled oil can lead to
engine damage.<
5Oil level sensor has failed
It is not possible to take a current or mean-
ingful measurement.
Do not add engine oil. It is possible to con-
tinue driving. Have the system checked as
soon as possible.
Adding engine oil
Add the maximum quantity of 1 US quart/1 liter
of oil only after the warning lamp in the instru-
ment cluster lights up, refer to page99, or when
the oil level measurement "+1.0 " appears on
the display.
Add oil within the next 125 miles/200 km;
otherwise, engine damage could result.<
Keep oil, grease, etc. out of reach of chil-
dren and heed warnings on the contain-
ers. Otherwise, you could endanger your
health.<
Oil change
Have the oil changed only by your BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil in between oil
changes. Only use oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for more details concerning BMW
High Performance Synthetic Oil or other
approved synthetic oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity classes
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climate conditions in the area where you
typically drive your BMW.
Approved oils belong to SAE classes
5W-40 and 5W-30.<
These oils can be used for driving in all ambient
temperatures.
