Things to remember when driving
Breaking-in
Moving parts need time to adjust to one
another. To ensure that your vehicle continues
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 the 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 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 done
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 page221.
General driving notes
Closing luggage compartment lid
Only drive with the luggage compartment
lid completely closed, otherwise exhaust
can penetrate into the passenger compart-
ment.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Coupe: close both windows and the glass
sunroof.
Convertible: with closed top, close all win-
dows.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page110.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated in 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
126 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 tire tread on page213.
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 at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver 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 driving on wet roads or in heavy rain, it is
a good idea to apply light pressure to the brake
pedal every few miles. Monitor traffic conditions
to ensure that this maneuver does not endan-
ger 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 thus reduced
efficiency of the brake system, downshift
to a gear in which only minimal brake applica-
tions are needed when descending long or
steep downhill stretches. Even light but consis-
tent 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 sport automatic transmis-
sion, refer to page61.
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 automatic climate
control during operation, and then exits under
the vehicle. Traces of condensed water under
the vehicle are therefore normal.

Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Sport automatic transmission
Insert the remote control into the ignition lock.
The engine can be switched off with the trans-
mission in neutral. Also refer to page38.
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 blow-out.<
Make sure that no fluids leak in the cargo
bay; otherwise the vehicle could be dam-
aged.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. 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.3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
800 lbs. and there will be four 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
200 lbs.:
800lbs. minus 600lbs. = 200lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.

The concept
Your BMW is equipped with a full mobile phone
preparation package. After a suitable mobile
phone has been paired in the vehicle once, you
can operate 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 as soon as it is
brought back inside the vehicle, provided that
the engine is running or the ignition is switched
on. The pairing data of up to four mobile phones
can be stored simultaneously. If several mobile
phones are detected simultaneously, the most
recently paired mobile phone 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 will fit in the snap-in adapters
they offer. These mobile phones support the
functions described in this Owner's Manual,
provided they are running a certain software
version. Malfunctions 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 separate Caring
for your vehicle brochure and in the mobile
phone operating instructions.
Operating options
You can operate the mobile phone* using:
>Buttons on steering wheel, refer to page11
>iDrive, refer to page16
>Voice commands, refer to page195
>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 "BMW Assist" or
"BMW Service" is displayed in "Communica-
tion", only BMW Assist calls are possible.

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 the buttons
on the steering wheel, refer to page11.
The setting is stored for the remote control cur-
rently in use.
Operation via iDrive
You can operate the following functions via
iDrive:
>Accepting/rejecting 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 vent outlets downward.
>Reduce the volume of the hands-free sys-
tem.

Changing between mobile
phone and hands-free system
From mobile phone to hands-free
system*
You can continue calls begun outside the Blue-
tooth range of the vehicle via the hands-free
system when the engine is running or the igni-
tion is switched on. Depending on your mobile
phone, the system automatically switches over
to the hands-free mode.
For mobile phones that do not automatically
switch over to the hands-free mode:
>Depending on the mobile phone model
used, the conversation can be continued via
the hands-free system if necessary. Follow
the instructions displayed on the mobile
phone display, refer to the operating
instructions of your mobile phone.
>Press the button above the storage
compartment. Switching over may take
several seconds.
From hands-free system to mobile
phone
When you telephone via the hands-free system,
you can also continue the call via the mobile
phone if necessary, depending on the mobile
phone model. Act according to what is shown
on the mobile phone display, refer to the oper-
ating instructions of your mobile phone.
As an alternative, you can deactivate the Blue-
tooth link.
Depending on your mobile phone model, poor
reception of the wireless communications net-
work can result in the system switching from
the hands-free system to the mobile phone.
Operation by voice*
The concept
You can operate your mobile phone without
having to remove your hands from the steering
wheel. When making your entries, you will be
supported by announcements or questions in
many cases.
