Air supply/blower
You can select blower speeds 1
to 4. The heating and ventilation
become more and more effective
as the air supply settings are
increased. In position 0, the blower
and heater are switched off. The air supply is
blocked in position 0.
Temperature
To increase the temperature of the
interior, turn to the right.
Air distribution
You can direct air to flow onto the
windows , toward the upper
body and into the footwell .
All intermediate settings are possi-
ble. In the setting, there is a
slight flow of air onto the windows to keep them
free of condensation.
Rear window defroster
When the rear window defroster is
activated, the indicator lamp
comes on. The rear window
defroster switches off automatically.
You can have your vehicle programmed in
such a way that the rear window defroster
switches on automatically. It is then switched
on at outside temperatures of less than approx.
+397/+46 within 5 minutes of the engine
start.<
Air conditioner
The air is cooled and dehumidified
and warmed again as needed,
depending on the temperature set-
ting. Depending on the weather, the windshield
may fog over briefly when the engine is started.
You can reduce condensation forming on the
windows by switching on the air conditioner.Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.<
Outside air/recirculated-air mode
You can respond to unpleasant
odors outside the vehicle by tem-
porarily switching off the outside
air supply. The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. The recirculated-air mode should not
be used over a sustained period of time, other-
wise the air quality inside the vehicle will deteri-
orate.<
Ventilation
The air vents for the upper body area can be
adjusted:
1Serrated dials
Serrated dials for opening and closing the
vent outlets through an infinitely-variable
range.
2Levers

A congenial climate
For almost all conditions, the AUTO pro-
gram 12 offers the optimal air distribution and
air volume. Select an interior temperature you
find pleasant.
The following section contains 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.<
Automatic air distribution and supply
The AUTO program adjusts the
airflow and distribution patterns for
you while also using your prese-
lected temperature setting as the basis for
adjusting the interior climate to adapt to exter-
nal influences: summer, winter.
The cooling is switched on automatically with
the AUTO program.
Individual air distribution
You can cancel the AUTO program
by selecting specific air distribu-
tion patterns for your personal
comfort, the automatic air supply
remains in operation. You can
direct air to flow onto the win-
dows , toward the upper body , and into
the footwell . You can reactivate the auto-
matic air distribution mode by selecting the
AUTO button.
Adjusting temperature
The figures in the display provide a
general indication of interior tem-
perature. When you start the vehi-
cle, the AUTO program ensures
that the selected temperature is
achieved as quickly as possible. It
then maintains this temperature, regardless of
the season.
Air supply/blower
You can vary the air supply by
pressing the upper or lower button.
This switches off the automatic
program for the air supply, and the
word AUTO goes out in the dis-
play. The automatic mode for air
distribution remains in operation as before. You
can reactivate the automatic air supply mode by
selecting the AUTO button.
If you press the lower button when at the lowest
blower speed, all displays go out: the blower,
heating and air conditioner are switched off.
The outside air supply is shut off. You can
restart the automatic climate control by press-
ing any of its buttons.
Defrosting windows and removing
condensation
This program quickly removes ice
and condensation from the wind-
shield and door windows.
Air conditioner
When the air conditioning 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 air conditioner
reduces the formation of condensation on the
windows.
The air conditioner can only operate when the
engine is running and is automatically switched
on with the AUTO program.
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.<

Things to remember when driving
Breaking-in
Moving parts should be allowed to adjust to one
another. To ensure that your vehicle provides
maximum economy throughout a long service
life, we request that you observe the following
instructions.
Engine and differential
Up to 1,200 miles/2,000 km:
Drive at varying engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h in the process:
Always obey all official speed limits.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
Once you have driven 1,200 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse before
the brake pads and rotors achieve the optimal
pad-surface and wear patterns required for
trouble-free operation and long service life later
on. To break in the separate handbrake drums,
apply the handbrake lightly when coasting to a
stop – at a traffic signal, for instance; use cau-
tion to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the vehicle
with the engine off – e.g. by towing – substan-
tially higher levels of pedal force will be required
to brake the vehicle.<
Clutch
The functio n of the clutch is als o only at its o pti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following component replacements
Observe the break-in instructions again if previ-
ously addressed components must be replaced
again during driving later.
General driving notes
Closing tailgate
Operate the vehicle only when the tail-
gate is completely closed, as 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
tailgate open:
1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioner or automatic climate control,
refer to page56 or59.

Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking take care to avoid pos-
sible 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.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. portable
phones, in 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.<
Inside rearview mirror, automatically
dimming*

The inside rearview mirror contains two photo-
cells that control the automatic dimming func-
tion. One is integrated into the mirror glass, the
other is located on the back of the mirror.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers on the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page28, as
otherwise they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor as otherwise dam-
age could result from undesired wiper activa-
tion, refer to page39.
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.<
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.<
Use 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. The best way to brake is to apply
maximum pressure to the brake pedal during
emergency: panic braking. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.

Things to remember when driving
74 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
While driving in wet conditions and in heavy
rain, it is a good idea to 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 which
is generated by the brake applications helps to
dry the brake pads and rotors. The full braking
force will then be available when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill gradients in the gear in which
the least braking is required. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
effect by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page37. This strategy helps you avoid
placing excessive loads on the brake system.
During slower downhill driving, use the HDC Hill
Descent Control, refer to page48.
Never drive with the clutch engaged, the
transmission in Neutral or with the engine
switched off, as otherwise there is no engine
braking when the transmission is in neutral, and
no power-assist for brakes and steering with
the engine switched off.
Never allow floor mats, carpets or other objects
to protrude into the area around the brake or
accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden air loss.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX Ibs. or YYY kg, as otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving comfort and – to a great extent – driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Checking pressure
Only check tire inflation pressure when the tires
are cold, i.e. 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 if necessary, including com-
pact wheel: at least every two weeks and before
beginning a longer trip. 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 a depressurized, i.e.
flat tire. A flat tire will seriously impair your vehi-
cle's handling and braking response. Attempts
to drive on a flat tire can lead to loss of control
over the vehicle.<
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page50.<
Inflation pressures for factory-installed
tires
The inflation pressures for your factory-
installed tires can be found on the door jamb
when you open the driver's door.
Inflation pressures for other tire sizes
The table below provides all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
For correct identification of the right tire
inflation pressure for your tires, observe
the specifications for the corresponding tire
sizes.<
Tire size
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
BMW Sports Activity Vehicle Center.

Wheels and tires
86
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or 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-
age and related safety hazards.<
Retreaded tires
BMW does not recommend the use of
retreaded tires, as otherwise driving
safety may be reduced. The causes for this
include the possibly different tire casing struc-
tures and the often wide variations in their age,
which can result in a limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always remember to have the specified
wheel-and-tire combination remounted on the
vehicle as soon as possible.
Recommended tire sizes and brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. These are available at a specialized
dealer, preferably your BMW Sports Activity
Vehicle Center. Observe any country-specific
regulations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on your vehicle; if properly cared
for, they will provide a combination of safety and
excellent ride comfort.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires
can lead to damage and accidents. Have this
work performed by skilled professionals only.
The technicians at your BMW Sports Activity
V e h i c l e C e n t e r w i l l b e g l a d t o a s s i s t y o u w i t h t h e
required professional knowledge and special-
ized equipment.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them against light whenever possible.
Protect the tires against contact with oil, grease
and fuel. Do not exceed the maximum tire infla-
tion pressure indicated on the side wall of the
tire.
