Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Coupe: head airbags, front and rear
3Side airbags in the seat backrests
Protective action
Observe the adjustment instructions on
page45 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 restraint. 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 situation, 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. Do not attach
seat covers, cushions or other objects not spe-
cifically approved for seats with integral side air-
bags to the front seats. Do not hang items of
clothing such as coats or jackets over the back-
rests. Do not attempt to remove the airbag
retention system from the vehicle. Do not mod-
ify the individual components of the system or
its wiring in any way. This includes the uphol-
stered 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 malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and 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 result 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 impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
activated, refer to Status of front passenger air-
bags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, refer to page56.

Things to remember when driving

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
Drive at varying engine and road speeds, but do
not exceed an engine speed of 4500 rpm or a
road speed of 100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down 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 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.
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 vehicle 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 the 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.
Check tire inflation pressure regularly
Check the tire inflation pressure 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 warm 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 to the forward vehicle. 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, accelerate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear 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 light, take your foot off
the accelerator and coast to a stop in the high-
est applicable gear.
O n a d o w n h il l s lo p e , t a k e y o u r f o o t o f f t h e a c c el -
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.
4 seconds.
Switch off functions you do not need at
the moment
Functions such as the air conditioner and the
seat or rear window heating draw large amounts
of power and consume additional fuel. Espe-
cially in city traffic and in stop and go driving
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 a
BMW center. Also note the BMW service sys-
tem, refer to page229.
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 the vehicle must be driven with the luggage
compartment lid open:
1.Close all windows and the glass roof.
2.Greatly increase the air volume of the auto-
matic climate control system, refer to
page106.
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. Do not touch hot exhaust tail pipes.
Otherwise there is a risk of burns.<
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.<

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.<
Coupe: roof-mounted
luggage rack*
A special rack system is available as an option
for your BMW. Comply with the directions given
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 page247.
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.
