Climate
110 By pressing the button repeatedly, you can
request three operating modes:
>LED off: outside air flows in continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
>Right LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
without interruption over an extended period of
time, as the air quality inside the vehicle deteri-
orates continuously.<
Residual heat
The heat stored in the engine is used to heat the
passenger compartment, e.g. while stopped at
a school to pick up a child.
Switching on
Pressing the right side switches on
the residual heat utilization when
the following conditions are met:
>up to 15 minutes after switching off the
engine
>with the engine at operating temperature
>with sufficient battery voltage
>at an outside temperature below 777/
256
REST appears on the display of the automatic
climate control when the residual heat utiliza-
tion is switched on.
From radio readiness the interior temperature,
the air volume and the air distribution can be
set.
Switching off
You can select the lowest blower speed by
pressing and holding the left side. Pressing
again switches off the residual heat utilization.
REST disappears from the display of the auto-
matic climate control.

Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. This com-
bined filter is changed during maintenance by
your BMW Sports Activity Vehicle Center.
You can select a display of more detailed infor-
mation on the Control Display, refer to page75.

and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Driving at a low engine speed reduces fuel con-
sumption and minimizes wear.
Taking advantage of coasting
The flow of fuel is interrupted when coasting.
Switching off engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad crossings, or in traffic
jams. Even having the engine switched off for
approx. 4 seconds results in fuel savings.
Switching off functions currently not
required
Functions such as air conditioning, seat heat-
ing, or rear window defrosting consume a lot of
energy and require additional fuel. Their influ-
ence is particularly pronounced in city traffic
and stop & go operation. For this reason, it is a
good idea to switch these functions off when
they are not really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW Sports
Activity Vehicle Center. Also please pay atten-
tion to the BMW maintenance system, refer to
page245.
General driving notes
Closing liftgate/tailgate
Operate the vehicle only when the tail-
gate and liftgate are completely closed.
Otherwise, exhaust fumes could enter into the
passenger compartment. gate open:
1.Close all windows and the panorama glass
sunroof.
2.Increase the air volume of the automatic
climate control to a high level, refer to
page108.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle and while
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, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot tailpipes, as
otherwise there is a danger of burns.<
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 the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tread depth on page238.
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 at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid

Things to remember when driving
130 possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page65. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise there will be no
engine braking action or support of the braking
force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
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 minimum
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.
When vehicle is parked
Condensation forms in the automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page51,
otherwise they could be damaged due to the
width of the vehicle.
Release the parking brake, particularly when
you have activated Automatic Hold, refer to
page61.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Mixed tires*
Before driving into a car wash, make sure
that the vehicle width is not too large for
the car wash, as otherwise the vehicle and the
car wash could be damaged.<
Rear window wiper
The rear window wiper can be damaged in car
washes. Take appropriate protective measures;
ask the car wash operator if necessary.
With comfort access*
Insert the remote control into the ignition lock.
The engine can be switched off in transmission
position N, also refer to page37.

Telephoning
214
Adjusting volume
Turn the knob during a call to select the desired
volume.
This volume for the hands-free system is main-
tained, even if the other audio sources are set to
minimum volume.
You can also adjust the volume with buttons on
the steering wheel, refer to page10.
The setting is stored for the remote control cur-
rently in use.
Operation via iDrive
You can operate the following functions via
iDrive:
>Accepting/refusing a call
>Dialing phone numbers
>Dialing phone numbers from the phone
book
>Dialing stored phone numbers, e.g. from the
list of accepted calls.
>Ending a call
When the ignition and radio readiness are
switched off, e.g. after removing the remote
control from the ignition lock, you can continue
an ongoing call via the hands-free system for no
more than 25 minutes.
Speech quality
If the person you are talking to cannot under-
stand you well, this may be due to excessively
loud background noises. The full mobile phone
preparation package can compensate for these
noises to a certain degree. To optimize the speech quality during a call, we recommend
that you:
>Reduce background noises, e.g. by closing
the windows, reducing the air volume of the
automatic climate control or pointing the
opened front air vents downward
>Reduce volume of hands-free system
Requirements
>The pairing data of the mobile phone are
stored in the vehicle and the mobile phone
is ready to operate.
>The engine is running or the ignition is
switched on.
>The mobile phone is detected by the vehi-
cle.

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 letter
Q = up to 100 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 US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT ... 1207 indicates that the
tire was manufactured in week 12 of 2007.
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 (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics 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.< e.g.
