Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child-restraint systems
appropriate for their age, weight and size. Oth-
erwise there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, size and weight.
Exception for front passenger seat
Should it be necessary to use a child-
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child-restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page73.
Installing child-restraint
systems
Observe the child-restraint system man-
ufacturer's instructions when selecting,
installing and using child-restraint systems.
Otherwise the protective effect may be dimin-
ished.<
Standard child-restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly or improperly installed child-restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child-restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated, otherwise there is an
increased risk of injury if the airbags deploy.<
Backrest width*
The backrest width of the front passen-
ger's seat must be at its widest possible
setting. Do not change the setting after install-
ing the child seat. Otherwise the child seat's
stability on the front passenger's seat is lim-
ited.<
1.Adjust the backrest width to its widest set-
ting, refer to page37.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger's
safety belt can be prevented from being pulled
out in order to fasten child-restraint systems.
To lock the safety belt
1.Secure the child-restraint system with the
belt.
2.Pull the belt strap all the way out.

Storage compartments inside
the vehicle
Depending on your vehicle's equipment, you
will find compartments beside the steering col-
umn
*, in the front doors and in the center con-
sole
*.
There are nets
on the front-seat backrests.
Storage compartments in the rear
console
Depending on your vehicle's equipment ver-
sion, the following storage compartments can
be found in the rear console:
>Storage tray
>Storage compartment with cover
>Cup holders
Coupe: clothes hooks
Press the upper edge to flip open.
Items of clothing hung from the hooks
must not obstruct the driver's view. Do
not hang heavy objects from the hooks, other-
wise they could endanger the car's occupants,
e.g. in case of heavy braking or sudden swerv-
ing.<
Cup holders
Use lightweight and shatterproof contain-
ers and do not transport hot beverages,
otherwise there is an increased risk of injury in
the event of the accident. Do not force contain-
ers that are too large into the cup holders, oth-
erwise damage could result.<
Front
Opening
Briefly press the center of the cover.
Closing
Briefly press the cover in the center and push in
the cup holder.
Rear*
There are two additional cup holders in the rear
console.
Press the button to open.
Before folding down the rear seat back-
rest or using the transport bag, remove all
containers from the cup holder and close it. Do
not place objects into the cup holder and do not
use force to close it. Do not use the cup holder
as a grab handle.<

Things to remember when driving
100 during brake applications to clean the rotors is
not reached.
This can also lead to a permanent loss in ride
comfort and to squealing noises during braking.
A loss in comfort can also be caused by
extended braking with little pressure on the
pedal.
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.
For information on brake system technology,
refer to Compound brake on page103.
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.
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. This can ultimately
result in a sudden blow-out.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
bay, as this could result in damage to the vehi-
cle.<
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-lb. pas-
sengers in your vehicle, the amount of avail-
able 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
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 the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.

Convertible: before opening the hardtop,
fold down the cargo bay partition. Make
sure the cargo bay is loaded correctly, other-
wise parts of the hardtop can be damaged, refer
to page91.<
>Secure smaller and lighter items using
retaining straps, a cargo bay net
* or draw
straps
*.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes are
provided for attaching the cargo straps.
Two are located on the cargo bay
sidewalls1, two more are on the rear cargo
bay panel2.
Please comply with the information sup-
plied with the cargo straps.
Position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page155, as excessive loads can pose a

Things to remember when driving
102 safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.
Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page45, otherwise these could be damaged.<
Coupe roof-mounted luggage
rack*
A luggage rack mounted on the roof
changes vehicle aerodynamics and han-
dling. Exercise restraint when driving with a
roof-mounted luggage rack to avoid the risk of
an accident.<
A special rack system is available as an option
f o r y o u r B M W . C o m p l y w i t h t h e d i r e c t i o n s g i v e n
in the installation instructions.
Mounting points
The mounting points are located in the roof.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the applicable data under Weights
on page155.The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure
that adequate clearance is maintained for rais-
ing the glass roof, and that objects do not
project into the opening path of the luggage
compartment lid.
Fasten roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.

>reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 16.6 US gal/63 liters, including the
reserve capacity of 3.3 US gal/12.5 liters.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel specifications
Do not fill the tank with leaded fuel, as this
would cause permanent damage to the
catalytic converter.
Do not fill the tank with E85, i.e. fuel containing
85Ξ ethanol, nor with FlexFuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
Required fuel
Super Premium Gasoline/AKI 93
Always use this premium grade fuel to obtain
maximum fuel economy and performance.
The minimum approved fuel grade is AKI 91.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10Ξ ethanol or other
oxygenates with up to 2.8Ξ oxygen by weight,
that is, 15Ξ MTBE or 3Ξ methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
driveability, starting and stalling problems especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter driveability 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
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
