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.

ing driving. An acoustic signal also
sounds and "+1.0 " is displayed in the
instrument cluster, refer to page103.
The oil level is at its absolute minimum; top off
e n g i n e o i l a s s o o n a s p ossible. 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

This process can last approx. 3 minutes
while standing on a flat surface and approx.
5 minutes while driving.

Under the hood
104 3Oil level at minimum
At your earliest opportunity, 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 page103, 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 the SAE classes
0W-40, 0W-30, 5W-40, and 5W-30.<
These oils can be used for driving in all ambient
temperatures.

Care
Car-care products
BMW recommends that your vehicle be
cleaned, cared for, and maintained using prod-
ucts that have been approved by BMW for this
purpose.
Regular cleaning and care makes a significant
contribution to maintaining the value of your
BMW.
Your BMW Sports Activity Vehicle Center will
be happy to advise you on products and ser-
vices for the cleaning, care, and maintenance of
your BMW.
Genuine BMW Care Products are materi-
als tested, lab tested, and field tested and
offer optimum care, maintenance, and protec-
tion for your vehicle.<
Do not use cleansers that contain alcohol
or solvents; they can damage your vehi-
cle.<
Cleaning agents can contain substances
that are dangerous or pose health risks.
For this reason, always read and comply with
the warnings and danger notices on the pack-
aging. Open the doors or windows on your vehi-
cle whenever cleaning the interior. Make sure
that there is sufficient ventilation when working
in enclosed spaces. Use only products that are
provided for cleaning vehicles.<
Exterior care
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Heavy soiling and
road salts can result in damage to the vehicle.<
After washing the vehicle, apply the
brakes briefly to dry them. Failure to do so
may lead to a reduction in braking efficiency and
also to corrosion of the brake rotors.<
Car washes
Give preference to cloth car washes.
Before driving into the car wash, check whether
the system is suitable for your BMW. To do so,
pay attention to the following points:
>Dimensions of your vehicle, refer to
page129
>If necessary: fold in the exterior mirrors,
refer to page33.
>Maximum permissible tire width.
Preparations for driving into the car wash:
>Deactivate rain sensor
* to prevent undes-
ired wiper operation.
>Deactivate rear window wiper and protect
from damage. Ask the operator of the car
wash about suitable protection measures
should the need arise.
>Remove additional add-on components,
e.g. spoilers or telephone antennas; other-
wise, they could be damaged.
Steam cleaners/high pressure cleaning
jets
When using steam cleaners or high pres-
sure cleaning jets, be sure to maintain a
sufficient distance and do not exceed a maxi-
mum temperature of 1407/606.
Insufficient distance or excessive pressure or
temperature can damage parts of the vehicle or
water can penetrate to the interior of the vehi-
cle. Follow the operating instructions for the
high pressure cleaning jet.<
Do not aim high pressure cleaning jets at
sensors such as those of the Park Dis-
tance Control for long periods of time and main-
tain a distance of at least 12 in/30 cm.<

Hand washes
When washing the vehicle by hand, use ample
water and optionally Auto Shampoo. Clean the
vehicle with gentle pressure, using a sponge or
a washing brush.
Before cleaning the windshield, deacti-
vate the rain sensor or switch off the igni-
tion in order to prevent undesired wiper activa-
tion.<
Obey local regulations for washing vehi-
cles by hand.<
Headlamps
Do not rub dry and never use abrasives or
strong solvents to clean the covers.
Use shampoo or insect remover to soften
insects and then rinse with ample water.
Remove accumulated ice and snow with win-
dow deicer, not a scraper.
Windows
Use glass cleaner to clean outer and inner sur-
faces of windows and mirror glass.
Do not clean mirror glass with cleansers
that contain powdered quartz.<
Wiper blades
Clean with soapy water and replace regularly to
prevent streaking.
Wax residues and dirt on the windshield
cause streaking during wiper operation
and lead to premature wear on wiper blades and
can cause the rain sensor to malfunction.<
Caring for vehicle finish
Regular care and maintenance helps your vehi-
cle retain its value and protects its finish against
the long-term effects of finish-damaging sub-
stances.
Environmental factors that occur locally or
regionally can have a negative impact on the fin-
ish of your vehicle and may damage it. It is
therefore important to adjust the frequency and
extent of vehicle care accordingly.Immediately remove particularly corrosive sub-
stances such as spilled fuel, oil, grease, brake
fluid, tree sap, or bird droppings; otherwise,
they can damage the finish.
Repairing damages to finish
Depending on the severity of the damage,
have stone damage or scratches touched
up immediately in order to prevent rust from
forming.<
BMW recommends having paint damage pro-
fessionally repaired in accordance with factory
guidelines using Genuine BMW finish materials.
Waxing
It is time to wax the vehicle when water no
longer beads on the clean surface of the paint.
Use only products that contain carnauba wax or
synthetic waxes to protect the finish.
Rubber seals
Only treat with water or rubber cleaner.
To avoid noise or damage, do not use
care products that contain silicone when
caring for rubber seals.<
Chrome parts
Carefully clean parts such as the radiator grille,
door handles, or window frames with ample
water and added shampoo, particularly when
they have been exposed to road salts. Use
chrome polish for additional treatment.
Light-alloy wheels
By design, the system produces dust during
braking, which settles on the light-alloy wheels.
Remove it frequently with an acid-free wheel
cleaner.
Do not use corrosive, acid-containing,
strongly alkaline, or coarse cleansers or
steam cleaners hotter than 1407/606; oth-
erwise, you can damage your vehicle.<
Aluminum running boards
Superficial rust on the aluminum running
boards can be removed with a special cleanser.

Care
110
Outside sensors
Keep sensors outside the vehicle, e.g.
Park Distance Control, clean and free of
ice in order to maintain full functionality.<
Interior care
Upholstery materials/cloth coverings
Clean regularly with a vacuum cleaner in order
to remove surface dirt.
With heavy soiling, such as spotting caused by
beverages, use a soft sponge or a lint-free
microfiber cloth in combination with suitable
interior cleaners. Follow instructions on the
packaging.
Clean upholstery material in large areas
extending all the way to the seams. Avoid
rubbing forcefully.<
Open Velcro-type fasteners on pants or
other items of clothing can damage the
seat covers. Make sure that Velcro-type fasten-
ers are closed.<
Leather/leather seat covers
The leather used by BMW is a high-qual-
ity natural product. Slight grain patterns
are part of the typical properties of a leather in
its natural state.<
Dust and road grime chafe in pores and folds,
leading to pronounced abrasion and premature
degradation of the leather surface. We there-
fore suggest that you clean the leather at fre-
quent intervals with a dust cloth or vacuum
cleaner.
Particularly with light-colored leather, make
sure that it is cleaned regularly since it tends to
soil more easily.
Treat the leather twice a year with a leather
lotion since dirt and grease break down the pro-
tective layer of the leather.
Carpets/cargo area
Floor carpeting and floor mats can be vacu-
u m e d o r w h e n m o r e h e a vily soiled, cleaned with
an interior cleaner.
Floor mats can be removed for cleaning. When
inserting them, make sure that the seat rails do
not protrude over the floor mats; otherwise the
floor mats can be damaged.
Fluff on floormats results from the production
process and can be removed by repeated vacu-
uming.
Plastic components inside
>Imitation leather surfaces
>Lamp lenses
>Covering glass of the instrument panel
>Matte components
Clean with water and solvent-free plastic
cleaner if so desired.
Fine wooden components
Use a damp cloth to clean fine wooden trim
panels and components. Follow up by drying
with a soft cloth.
Safety belts
Do not clean with cleansers; this can
destroy the webbing.<
Displays
Use a display-cleaning cloth or a soft, nonabra-
sive, lint-free cloth to clean displays, e.g. of the
radio or the instrument panel.
Avoid rubbing too forcefully when clean-
ing displays; otherwise, you can damage
them.<
Never use chemical-based cleansers or
scouring household cleansers. Keep all
liquids away from the equipment. Moisture can
attack or damage the surfaces of electrical
components.<
CD/DVD players
Do not use cleaning CDs; they can dam-
age parts of the player.<
