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 driving 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.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
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.
Removing 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.
Closing windows and glass sunroof
An open glass sunroof or open windows like-
wise increase the drag coefficient and therefore
the fuel consumption.
Checking 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
Use 1st gear only for starting off. Accelerate
rapidly in 2nd gear and above. Avoid high
engine speeds in doing so and shift into the
next gear early.
When you have reached the desired speed,
shift into the highest possible gear and drive
with the lowest possible engine speed while
maintaining a constant a vehicle speed.
In general: driving at a low engine speed
reduces fuel consumption and minimizes wear.
Taking advantage of coasting
When approaching a red light, let off the gas
and allow the vehicle to coast to a stop in the
highest possible gear.
On steep roadways, let off the gas and allow the
vehicle to roll in the appropriate gear.
The flow of fuel is interrupted when coasting.
Switching off the 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 center. Also
please pay attention to the BMW maintenance
system, refer to page237.
General driving notes
Closing luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is com-
pletely closed. Otherwise, exhaust fumes could
enter the interior of the vehicle.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Close all windows and the glass sunroof or
panorama glass sunroof.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page115.
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 exhaust tail
pipes. Otherwise there is a risk 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

Things to remember when driving
136 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, refer also to Mini-
mum tire tread on page229.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle in
place for a long time by riding the clutch;
use the handbrake. Otherwise greater clutch
wear will result.<
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
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, if necessary all the
way down into first gear. This strategy helps
you avoid placing excessive loads on the brake
system. For information on downshifting in the
manual mode of the automatic transmission,
refer to page64.
Do not drive with the clutch depressed, in
idle or with the engine switched off, other-
wise 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 air conditioner sys-
tem 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 page53,
otherwise they could be damaged due to the
width of the vehicle.

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 logon 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 cen-
ter 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 traffic conditions
allow 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 distracted
can endanger vehicle occupants and other road
users.<
Suitable mobile phones
Ask your BMW 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. Malfunctions can occur with
other mobile phones.
Care instructions
You can find valuable information on this topic
under Care, starting on page239 and the oper-
ating instructions for the mobile phone.
Operating options
You can operate the mobile phone* using:
>Buttons on steering wheel, refer to page11
>iDrive, refer to page16
>Voice commands, refer to page205
>Programmable memory 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 "BMW Assist" or
"BMW Service" is displayed in "Communica-
tion", 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
progress. If this happens, you must log off the
