Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and vehicle speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
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. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Remove add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Close windows and glass sunroof
An open glass sunroof or open window likewise
increases the drag coefficient and therefore the
fuel consumption.
Check tire inflation pressures regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.
Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
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.
Switch 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
page243.
General driving notes
Closing liftgate
Operate the vehicle only when the liftgate
is completely closed. Otherwise, exhaust
fumes could enter into the passenger compart-
ment. gate open:
1.Close all windows and the glass sunroof.
2.Increase the air volume of the automatic
climate control to a high level, refer to
page105.
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 page236.
Driving through water
Do not drive through water on the road if it
is deeper than 18 in/45 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
128 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 page62. 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 page50,
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
page58.
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.<
With comfort access*
Insert the remote control into the ignition lock.
The engine can be switched off in transmission
position N, also refer to page38.
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 blow-out.<

>If you want to drive on very steep uphill or
downhill gradients, make sure beforehand
that the engine oil and coolant levels are
near the MAX mark, refer to page240.
>On very steep downhill slopes, use Hill
Descent Control HDC, refer to page87.
>While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenever possible.
>Please make sure that the undercarriage
does not touch the ground, for example on
crests and bumpy roads. The ground clear-
ance of the vehicle is a maximum of approx.
8 in/20 cm. Please note that the ground
clearance can vary depending on loading
and the driving conditions of the vehicle.
>Only drive through water on roads up to a
maximum depth of 18 in/45 cm and only at
walking speed, making sure not to stop in
the process.
>After driving through water at low speed,
lightly press the brake pedal several times
to dry the brakes and to prevent the braking
effect from being reduced by wetness.
>Depending on the condition of the surface,
it may be practical to briefly activate DTC,
refer to DTC Dynamic Traction Control on
page86.
>If the drive wheels spin on one side, depress
the accelerator pedal sufficiently so that the
driving stability control systems can distrib-
ute the drive forces to the individual wheels.
Please note the following points after driving on
poor roads to maintain the driving safety of your
BMW:
>Clean the coarsest dirt from the body.
>Clean mud, snow, ice etc. from the wheels
and tires and check the tires for damage.

The concept
Your BMW is equipped with a full mobile phone
preparation package. After pairing a suitable
mobile phone in the vehicle once, you can oper-
ate the mobile phone via iDrive, with the buttons
on the steering wheel and by voice.
A mobile phone that has been paired once is
automatically detected again with the engine
running or the ignition switched on as soon as
it is in the vehicle interior. The pairing data of up
to four mobile phones can be stored simulta-
neously. If several mobile phones are detected
simultaneously, the respective last mobile
phone paired can be operated via the vehicle.
Using a phone in your vehicle
Using snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW
Sports Activity Vehicle Center which mobile
phones snap-in adapters are offered for.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate operating instructions for a
detailed description of safety precautions and
information, we request that you direct your
particular attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do
not observe this precaution, your being dis-
tracted can endanger vehicle occupants and
other road users.<
Suitable mobile phones
Ask your BMW Sports Activity Vehicle Center
which mobile phones with a Bluetooth interface
are supported by the mobile phone preparation
package or which mobile phones snap-in
adapters are available for. These mobile phones
support the functions described in this Owner's
Manual with a certain software version. Mal-
functions can occur with other mobile phones.
Care instructions
You can find what you need to know about car-
ing for your mobile phone in the Caring for your
vehicle brochure and in the separate mobile
phone operating instructions.
Operating options
You can operate the mobile phone* using:
>Buttons on steering wheel, refer to page11
>iDrive, refer to page212
>Voice commands, refer to page217
>Programmable memory/direct selection
buttons, refer to page21
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
Placing phone calls with BMW Assist
system*: BMW Assist calls
You can use the BMW Assist system via the
hands-free unit for BMW Assist calls.
When the status information "Communication"
or "BMW Assist" is displayed in "BMW Ser-
vice", only BMW Assist calls are possible.
It may not be possible to establish a telephone
connection using the mobile phone while a con-
nection is being established to BMW Assist or
while a call to BMW Assist is already in

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
