Airbags
The following airbags are located under the
marked covers:
1
Front airbags
2 Coupe: head airbags
3 Side airbags in the seat backrests
4 Convertible: knee airbags
Protective action
Observe the adjustment instructions on
page 47 to ensure the best possible per-
sonal protection. <
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restrain t. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision si tuation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Keep the dashboard and windows on the front
passenger side clear, i. e. do not cover with
adhesive labels or coveri ngs, and do not attach
holders such as for navi gation instruments or
mobile phones.
Do not attach seat cove rs, cushions or other
objects not specifically approved for seats with integral side airbags to the front seats. Do not
hang items of clothing such as coats or jackets
over the backrests. Do
not attempt to remove
the airbag retention system from the vehicle. Do
not modify the individu al components of the
system or its wiring in any way. This includes
the upholstered covers on the steering wheel,
instrument panel, seats and roof posts, as well
as the sides of the roof lining. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of faults, immobilization, or after the
airbag system has been triggered, have the
testing, repair, or disassembly and scrapping of
gas generators performe d only by your BMW
center or a workshop that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could resu lt in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impr ession in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passe nger are activated or
deactivated by the system accordingly.

Things to remember when driving
Vehicle equipment
In this chapter, all pr oduction, country, and
optional equipment that is offered in the model
range is described. As a result, some equip-
ment described may not be available in a partic-
ular vehicle, for example due to the options or
national-market version selected. This also
applies to safety related functions and systems.
Break-in period
Moving parts need breaking-in time to adjust to
each other. Please follo w 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
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4,500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do no t 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 clut ch 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 renewe d in the course of the
vehicle's operating life.
Saving fuel
The fuel consumption of your vehicle depends
on several factors. You can lower fuel consump-
tion and the environmental impact by taking
certain measures, adjusting your driving style
and having the vehicl e serviced regularly.
Remove any unneeded cargo
Additional weight increases fuel consumption.
Remove any mounted parts after you
have finished using them
Remove unneeded additional mirrors, the roof
rack and the rear luggage rack after use.
Mounted parts affect th e vehicle's aerodynam-
ics and increase fuel consumption.
Close the windows and glass roof
An open glass roof or window causes higher air
resistance and thus increases fuel consump-
tion.

Driving tips
Check tire inflation pressure regularly
Check the tire inflation pr
essure at least twice a
month and before embarking on a long journey,
and correct it if necessary.
Low tire inflation pressure causes higher rolling
resistance and thus increases fuel consumption
and tire wear.
Set off immediately
Do not let the engine wa rm up while the car is
still standing, but set off immediately at moder-
ate engine speed. This is the fastest way for the
cold engine to reach its operating temperature.
Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and th e vehicle in front of
you. A defensive and smooth driving style
keeps fuel consumption down.
Avoid high engine speeds
Only use first gear when setting off. In second
and higher gears, accele rate without hesitation
or pauses. When accelera ting, shift up before
reaching high engine speeds.
When you reach the desi red speed, shift into
the highest applicable ge ar and drive with the
engine speed as low as possible and at a con-
stant speed.
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Coasting
When approaching a red lig ht, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
On a downhill slope, take your foot off the accel-
erator and coast in a suitable gear.
The fuel supply is interrupted when coasting.
Switch off the engine during lengthy
stops
Switch off the engine when stopping for lengthy
periods, e.g. at traffic lights, railroad crossings
or in traffic congestions. You achieve fuel sav-
ings even if standing time is as short as approx.
4seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner, seat
heating or rear window defroster draw large
amounts of power and consume additional fuel.
Especially in city traffic and in stop-and-go driv-
ing they have a considerable impact. Therefore,
switch these functions off when they are not
really needed.
Have the vehicle serviced
Have the vehicle serviced regularly to achieve
good economy and a long vehicle life. BMW
recommends having the vehicle serviced at
your BMW center. Also note the BMW service
system, refer to page 264.
General driving notes
Close the trunk lid
Only drive with the trunk closed. Failure to
do so may endanger passengers or other
road users or may damage the vehicle in the
event of an accident or a braking and evasive
maneuver. In addition, exhaust gas may flow
into the passenger compartment. <
If special circumstances make it absolutely nec-
essary to drive with the trunk open:
1. Close all windows and the glass roof.
2. Greatly increase the ai r volume of the auto-
matic climate control system, refer to
page 118.
3. Drive cautiously.

Driving tips
Securing cargo
Coupe
Convertible
>
Secure smaller and lighter items using
retaining straps, a carg o area net, or draw
straps.
> Heavy-duty cargo straps for securing larger
and heavier objects are available at your
BMW center. Four lashing eyes are pro-
vided for attaching the cargo straps. Two
are located on the side walls of the cargo
area 1, two additional ones are located on
the inside wall of the cargo area 2.
Please note the information supplied with
the cargo straps.
Convertible: before opening the hardtop,
fold down the cargo ar ea partition. Make
sure the cargo area is loaded correctly; other-
wise parts of the hardto p can be damaged, refer
to page 130.<
Always 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 page
287; otherwise, excessive loads can
pose a safety hazard and may also place you in
violation of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, sinc e 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 st raps using the lashing
eyes shown in the illust ration. Do not secure
cargo with the anchors for tether straps, refer to
page 59; otherwise, these could be damaged. <
Coupe: roof-mounted
luggage rack
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 page 287.

Driving tipsThings to remember when driving
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 tilting
the glass roof, and that objects do not project
into the opening path of the trunk lid.
Fasten roof-mounted cargo correctly and
securely to prevent it fr om shifting or falling off
during the trip.
Drive smoothly. Avoid su dden acceleration and
braking maneuvers. Ta ke corners gently.
