Notes

For your own safety
Fuels
Use unleaded gasoline only.
Fuels containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight – that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent – will not void
the applicable warranties with respect to
defects in materials or workmanship. Field
experience has indicated significant differ-
ences in fuel quality – volatility, composi-
tion, additives, etc. – among gasolines
offered for sale in the United States and
Canada. The use of poor-quality fuels may
result in drivability, starting and stalling
problems, especially under certain environ-
mental conditions such as high ambient
temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.<
Maintenance and repair
Advanced technology, e. g. the use of
modern materials and high-perfor-
mance electronics, requires specially
adapted maintenance and repair methods.
Therefore, only have corresponding work
on your BMW carried out by a BMW center
or a workshop that works according to
BMW repair procedures with correspond-
ingly trained personnel. If work is carried
out improperly there is a danger of conse-
quential damage and the related safety
risks.<
Parts and accessories
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Genuine BMW
Parts, you simultaneously acquire the
assurance that they have been thoroughly
tested by BMW to ensure optimum perfor-
mance when installed on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for dam-
age resulting from installation of parts and
accessories not approved by BMW.
BMW cannot test every product made by
other manufacturers to verify if it can be
used on a BMW safely and without risk to
either the vehicle, its operation, or its occu-
pants.
Genuine BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW
centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones – including operation of
any portable phone from within the vehicle
without using an externally mounted
antenna – or transceiver equipment, for
instance, CBs, walkie-talkie, ham radio or
similar accessories, may cause extensive
damage to the vehicle, compromise its
safety, interfere with the vehicle's electrical
system or affect the validity of the BMW
Limited Warranty. Refer to your BMW cen-
ter for additional information.<
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part.<

Transporting children safely
The right place for children
Children always in the rear
Accident research shows that the safest
place for children in a vehicle is in the rear
seat.
Older children should be tightly secured
with a safety belt, after they have outgrown
a booster seat that is appropriate for their
age, height and weight.
Child-restraint system in the rear
Children under 13 years of age and
children less than 5 ft/150 cm tall
should always ride in the rear and the
restraint systems should be secured with
the vehicle's safety belts.<
Younger children should be secured in an
appropriate forward-facing child-restraint
system that has first been properly
secured. We strongly urge you to carefully
read and comply with the instructions for
installation and use provided by the child-
restraint's manufacturer whenever you use
such a device.
All rear sitting positions in your vehicle
meet the recommendations of SAE J1819,
an industry-recommended practice for
securing child-restraint systems in motor
vehicles.
Exception for front passenger seat
Should it become necessary to use
a child-restraint system on the front
passenger seat, the airbags on the passen-
ger's side must be deactivated. Deactivat-
ing the passenger airbags is only possible
on the Coupe. Your BMW center will be
glad to advise you. restraint system in the front passen-
ger seat of this vehicle if the passenger air-
bag is not deactivated. If you do so, the
child could be severely injured when the
airbag is triggered.
Your vehicle is equipped with an airbag
supplemental restraint system for the front
passenger. Because the backrest on any
rearward-facing child-restraint system – of
the kind designed for infants under 1 year
and 20 Ibs./9 kg – would be within the air-
bag's deployment range, you should never
mount such a system in the front passenger
seat, since the impact of the airbag against
the child restraint's backrest could lead to
serious or fatal injuries.<
Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Observe the child-restraint system
manufacturer's instructions for instal-
lation and use. Otherwise the degree of
protection can be reduced.
After an accident, have all parts of the
child-restraint system and of the relevant
vehicle safety belt system checked by a
BMW center and replaced if necessary.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.

Things to remember when driving
104
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.

Stowing cargo
>Load heavy cargo as far forward and
as low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners.
Securing cargo
>Use the luggage net* or securing straps
to hold down small and lightweight lug-
gage and cargo
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available
at your BMW center. Four lashing eyes
fitted in the luggage compartment are
used to secure these heavy-duty cargo
straps, refer to arrows
>Please observe the special instructions
supplied with the heavy-duty cargo
straps.
Always position and secure the load
as described above. If you do not, it
can even endanger the passengers during
braking or evasive maneuvers.
Never exceed either the approved gross
vehicle weight or either of the approved
axle loads, refer to page 190, as excessive
loads can pose a safety hazard, and may also place you in violation of freeway safety
laws.
You should never transport heavy or hard
objects unsecured in the passenger com-
partment, as they could fly around and
even pose a safety hazard to the vehicle's
occupants during abrupt braking or evasive
maneuver.<
Pad on base of luggage
compartment
If required, you can use the pad e.g. to
transport dirty or soiled objects. The rub-
berized side is washable and has an anti-
slip effect.

mined according to the so-called (R+M)/
2 method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic
converter will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight, that is,

alent amount of co-solvent, will not void
the applicable warranties with respect to

result in drivability, starting and stall-
ing problems, especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may also result in unscheduled main-
tenance.<
