Integrated universal remote
control*
The concept
The integrated universal remote control
replaces up to three different hand-held
transmitters for various items of radio-con-
trolled equipment such as door openers
and house alarm systems. The integrated
universal remote control registers and
stores signals from the original hand-held
transmitters.
The signal of an original hand-held trans-
mitter can be programmed on one of the
three memory buttons 1. Then the respec-
tive device can be actuated with the mem-
ory button 1 programmed for its use with
the ignition key in position 2. The indicator
lamp 2 flashes to confirm transmission of
the signal.
If you sell your vehicle one day, delete the
saved programs beforehand for your own
security, refer to page 95.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control, always
inspect the immediate area to make certain
that no people, animals or objects are
within the travel range of the device. Also,
comply with the safety precautions of the
original hand-held transmitter.<
Checking compatibility
If you see this symbol on the pack-
aging or in the manual supplied with
the original hand-held transmitter, it
is safe to assume that it is compatible with
the integrated universal remote control.
If you have additional questions, please
consult your BMW Sports Activity Vehicle
Center or call 1-800-355-3515.

Fixed-code hand-held transmitters
1.Ignition key in position 2
2.When using for the first time: press both
outer buttons 1 for approx. 20 seconds,
maintaining pressure until the indicator
lamp 2 starts to flash. The three mem-
ory buttons 1 are cleared
3.Hold the original hand-held transmitter
at a distance of approx. 2 in/5 cm to
8 in/20 cm to the memory buttons 1
The required distance between
the hand-held transmitter and the
memory buttons 1 depends on the rele-
vant system of the original hand-held
transmitter used.<
4.Simultaneously press the transmit but-
ton on the original hand-held transmit-
ter and the desired memory button 1 on
the integrated universal remote control.
Initially, the indicator lamp 2 flashes
slowly. Release both buttons as soon
as the indicator lamp 2 flashes rapidly.
If the indicator lamp 2 does not flash
rapidly after approx. 15 seconds,
change the distance
5.To program other original hand-held
transmitters, repeat steps 3 and 4.

Things to remember when driving
Break-in procedures
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 following section.
Engine and differential
Up to 1,200 miles/2,000 km:
You should attempt to vary both vehicle
and engine speeds. Until the break-in
period has been completed, you should
also refrain from exceeding an engine
speed of 4500 rpm or a driving speed of
100 mph/160 km/h.
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle speeds
can be gradually increased.
SMG Sequential manual
transmission
Do not use the acceleration assistant dur-
ing the break-in period, refer to page 60.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction 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 opti-
mized contact and wear patterns between
brake pads and rotors.
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.
After component replacement
You should also comply with these break-in
procedures should the components men-
tioned above need to be replaced at a later
point.
General driving notes
Hot exhaust system
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to vari-
ous sections of the exhaust system, 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 prop-
erty damage as well as personal injury.<
Parking vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors manually, as
otherwise they could be damaged due to
the width of the vehicle.
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 surface. This phenomenon is referred
to as hydroplaning, and is characterized
by a partial or complete loss of contact
between the tires and the road surface, ulti-
mately 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 Tire tread on page 167.
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 vehicle's engine, the electri-
cal systems and the transmission may be
damaged.<
Braking safely
Your BMW is equipped with ABS as stan-
dard. The best way to achieve optimized
braking response from the ABS is to apply
maximum pressure to the brake pedal in
situations where this is required: panic
stops. Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a minimum
of steering effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indi-
cate to the driver that ABS is in its active
mode.
Do not drive with your foot resting on
the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.<
Driving in wet conditions
While driving in wet conditions and 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 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 thus
reduced efficiency of the brake sys-
tem, downshift to a gear in which only min-
imal brake applications are needed when
descending long or steep downhill
stretches. Even light but consistent pedal
pressure can lead to high temperatures,
brake wear and possibly even brake fail-
ure.<
You can further enhance the engine's brak-
ing effect by selecting a lower gear in the
automatic transmission's manual mode,
downshifting as far as first gear on
extremely steep stretches, refer to
page 59. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
Never drive with the clutch pressed
or allow the vehicle to coast with the
transmission in Neutral – or with the engine
switched off – there is no engine braking
when the transmission is in Neutral, and no
power assist for brakes and steering when
the engine is not running.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion on brake rotors
When the vehicle is driven only occasion-
ally, 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 ten-
dency 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 pul-
sating effect that even extended applica-
tion will fail to cure.

Things to remember when driving

Mobile communication devices in
vehicle
BMW advises against using mobile
communication devices, e.g. portable
phones, in the inside of the vehicle without
a direct connection to an external antenna.
Otherwise, the vehicle electronics and
mobile communication device can influ-
ence one another. It is not ensured that the
waves emitted during transmission are led
out of the vehicle interior.<
Cargo loading
To avoid loading the tires beyond
their approved carrying capacity,
never overload the vehicle. Overloading
can lead to overheating and increases the
rate at which damage develops inside the
tires. The ultimate result can assume the
form of a sudden air loss.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occu-
pants and cargo should never
exceed XXX lbs. or YYY kg, as other-
wise the vehicle may be damaged and
unstable driving conditions 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 kg4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
1400 lbs. and there will be five 150-lbs.
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs.:
1400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of lug-
gage 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 permitted 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.

TeleService , BMW Assist
TeleService
TeleService supports you in communicat-
ing with your BMW center. The installed car
phone can be used to transmit data on the
service status of your vehicle or on legally
mandated inspections directly to your
BMW center. This is the same data that is
also stored for CBS Condition Based Ser-
vice in the ignition key. Your BMW center
can then contact you, and you can make an
appointment that suits you while you are
still on the road. Your advantage is that
your BMW center can prepare in advance
for the required maintenance work. The
functions of TeleService are country-spe-
cific: the data on the service status of your
vehicle or on legally mandated inspections
is transmitted on a country-specific basis
either automatically before they fall due or
simultaneously when you call your BMW
center. Your BMW center will be glad to
provide more detailed information.
BMW Assist
BMW Assist provides you – in addition to
TeleService – with other services, e.g. the
position data of your vehicle can be trans-
ferred to the BMW Assist emergency call
center if an emergency call is started.
Many functions of BMW Assist depend on
the individually agreed contract. The data
transmission, e.g. of CBS Condition Based
Service, is different in individual countries.
The subscriber agreement must be com-
pleted successfully before using the BMW
Assist services.
Requirements
The installed car phone is logged on to a
portable telephone network. This network
must be able to transmit the services.To transmit position data, the vehicle must
be able to determine the current position.
This is displayed on the Control Display. In
order to enable and update TeleService or
BMW Assist, a GPS signal must be present.
Enabling TeleService or BMW Assist
For you to be able to use the services of
TeleService or BMW Assist, these must be
enabled.
Leave the ignition key in position 1 during
the entire operation.

Using tow fitting
The threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment under the floor mat, refer to
page 178, and should always remain in the
vehicle. It can be screwed in at the front or
rear of the BMW.
To avoid damage to the tow fitting
and the vehicle, observe the follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Only use the tow fitting to tow on the
roadway. Avoid heavy lateral loading of the
tow fitting, e.g. do not lift the vehicle by the
tow fitting.<

Being towed
Even if there is a failure in the electri-
cal system, make sure that the igni-
tion key is in position 1, as otherwise the
steering wheel could lock and it would be
impossible to steer the vehicle. There is no
power assist with the engine stopped. This then requires increased effort for braking
and steering. The active steering is deacti-
vated; when stopped and in the low speed
range greater steering wheel movements
are required.<
Switch on the hazard warning flashers
depending on the local regulations. If the
electrical system fails, mark the vehicle to
be towed, e.g. with a sign or warning trian-
gle in the rear window.
Vehicles with manual transmission
Gearshift lever in idle position
Vehicles with automatic
transmission

Do not exceed a towing speed of
45 mph/70 km/h and a towing dis-
tance of 90 miles/150 km, as otherwise the
automatic transmission may be dam-
aged.<
Vehicles with SMG Sequential

Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with all regulations on
towing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as oth-
erwise it will not be possible to control
vehicle response.<
The tow fittings used should be on the
same side on both vehicles. Should it prove
impossible to avoid mounting the tow bar
at an offset angle, please observe the fol-
lowing:
