Practical interior accessories
104 The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.
You can operate the system when the engine is
running or when the ignition is switched on.
If the system fails to function even after
repeated programming, check whether
the original hand-held transmitter uses an alter-
nating-code system. To do so, either read the
instructions for the original hand-held transmit-
ter or hold down the programmed memory
button1 of the integrated universal remote
control. If the LED2 on the integrated universal
remote control flashes rapidly for a short while
and then remains lit for about two seconds, the
original hand-held transmitter uses an alternat-
ing-code system. If it uses an alternating-code
system, program the memory buttons1 as
described under Alternating-code hand-held
transmitters.<
Alternating-code hand-held
transmitters
To program the integrated universal remote
control, consult the operating instructions for
the device to be set. You will find information
there on the possibilities for synchronization.
When programming hand-held transmitters that employ an alternating code, please observe
the following supplementary instructions:
Programming will be easier with the aid of
a second person.<
1.Park your vehicle within the range of the
remote-controlled device.
2.Program the integrated universal remote
control as described above in the section
Fixed-code hand-held transmitters.
3.Locate the button on the receiver of the
device to be set, e.g. on the drive unit.
4.Press the button on the receiver of the
device to be set. After step 4, you have
approx. 30 seconds for step 5.
5.Press the programmed memory button1 of
the integrated universal remote control
three times.
The corresponding memory button 1 is now
programmed with the signal of the original
hand-held transmitter.

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follow the instructions below
in order to achieve the optimal service life and
economy of operation for your vehicle.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Attempt to vary both engine and vehicle
speeds, but refrain from exceeding an engine
speed of 4,500 rpm or a driving speed of
100 mph or 160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode.
After 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Sequential manual gearbox SMG
Do not use the acceleration assistant during the
break-in period, page57.
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 cautiously 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 cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx. 300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Close the luggage compartment lid
Operate the vehicle only when the lug-
gage compartment lid is closed. Other-
wise, exhaust fumes could enter the interior of
the vehicle.<
If special circumstances make it absolutely nec-
essary to drive with the luggage compartment
lid open:
1.Close all windows and the glass sunroof.
2.Increase the air flow rate of the automatic
climate control considerably, refer to
page99.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to various sections of the exhaust sys-
tem, and never apply undercoating to them.
When driving, standing at idle and while park-
ing, 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, with the
risk of serious personal injuries and property
damage.<
Mobile phone in the vehicle
BMW discourages the use of mobile
communications devices, e.g. mobile
phones, inside the vehicle without a direct con-

nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.
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 situation, known as hydroplaning,
means that the tire can completely lose contact
with the road surface, so that neither the car can
be steered nor the brake be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page195.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the vehicle's engine, the electrical systems and the
transmission may be damaged.<
Use the handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page87.
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. 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.
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 brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<

Things to remember when driving
118 You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page58.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
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 the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
For general information about taking care of
your BMW, refer to the Caring for your vehicle
brochure.
With convenient access and automatic
transmission
Insert the remote control into the ignition
switch.The engine can be switched off when the selec-
tor lever is in position N. Refer also to page36.
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.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
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 kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150 lbs.
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available

The concept
Your BMW is equipped with a full mobile phone
preparation package. After pairing a suitable
mobile phone with the vehicle once, you can
operate the mobile phone via iDrive, the buttons
on the steering wheel or via voice commands.
Once a mobile phone has been paired with your
vehicle, it is automatically recognized as soon
as it is inside the vehicle while the engine is run-
ning or the ignition is switched on. You can
store the pairing data for up to four mobile
phones simultaneously. If several mobile
phones are detected at the same time, the
mobile phone last paired can be operated via
the vehicle.
Using the telephone inside
the vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a holder for
mobile phones, allows you to charge the mobile
phone's battery and connect the mobile phone
to your vehicle's outside antenna. This ensures
better network reception and consistent repro-
duction quality. Please contact your
BMW Center to find out for which mobile
phones there are snap-in adapters available.
BMW discourages the use of mobile
phones or other mobile communications
devices inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, inter-
ference between vehicle electronics systems
and the mobile communications device cannot
be ruled out. In addition, there is no assurance
that the radiation which results from transmis-
sion will be dissipated from the vehicle inte-
rior.<
Avoid operating a mobile phone recognized by
the vehicle via the mobile phone's keypad, oth-
erwise malfunctions may result.
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 Owner's Manual for a detailed
description of safety precautions and informa-
tion, 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
Please ask your BMW Center which mobile
phones with Bluetooth interface are supported
by the mobile phone preparation package and/
or which mobile phones are compatible with the
snap-in adapter. By virtue of their particular
software versions, these mobile phones sup-
port the functions described in this Owner's
Manual. Malfunctions may 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 Owner's Manual.
Operating options
You can operate the mobile phone* using:
>The steering wheel, refer to page10
>iDrive, refer to page170

troller.
The next time you use the mobile phone inside
the vehicle, it will be recognized within no more
than two minutes as long as the engine is run-
ning or the ignition is switched on.
As soon as a mobile phone is detected by the
vehicle, the phone book entries stored on the
SIM card or on your mobile phone are transmit-
ted to the vehicle. Refer also your mobile
phone's operating instructions, if necessary.
This data transfer depends on your mobile
phone and can take several minutes; please
refer to your mobile phone's operating instruc-
tions, if necessary.
Up to four mobile phones can be paired, one
after the other. If a fifth mobile phone is paired,
the pairing data for the last mobile phone on the
list is deleted, refer also to the information
below.
