Personal Profile
The concept
You can set a number of functions of your BMW
individually according to your preferences.
Personal Profile ensures that most of these set-
tings are stored for the remote control currently
in use without you having to do anything. When
the vehicle is unlocked, the corresponding
remote control is detected and the settings
stored for it are called up and carried out.
This means that you will always find your BMW
set to your own personal settings even if
another person with his/her own remote control
and settings has used the vehicle since the last
time you drove it. The individual settings are
stored for a maximum of four remote controls.

Details on the settings are provided on the
specified pages.

Energy Control
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters, including the reserve capacity of
approx. 2.1 US gal/8 liters.
550i: approx. 2.6 US gal/10 liters reserve
capacity.
You will find information on refueling on
page218.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.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.<

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
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 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 optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
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.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof
An open glass sunroof or open windows like-
wise increase the drag coefficient and therefore
the fuel consumption.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.

Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Use 1st gear only for starting off. Accelerate
rapidly in 2nd gear and above. Avoid high
engine speeds in doing so and shift into the
next gear early.
When you have reached the desired speed,
shift into the highest possible gear and drive
with the lowest possible engine speed while
maintaining a constant a vehicle speed.
In general: driving at a low engine speed
reduces fuel consumption and minimizes wear.
Taking advantage of coasting
When approaching a red light, let off the gas
and allow the vehicle to coast to a stop in the
highest possible gear.
On steep roadways, let off the gas and allow the
vehicle to roll in the appropriate gear.
The flow of fuel is interrupted when coasting.
Switching off engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad crossings, or in traffic
jams. Even having the engine switched off for
approx. 4 seconds results in fuel savings.
Switching off functions currently not
required
Functions such as air conditioning, seat heat-
ing, or rear window defrosting consume a lot of
energy and require additional fuel. Their influ-
ence is particularly pronounced in city traffic
and stop & go operation. For this reason, it is a
good idea to switch these functions off when
they are not really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW center. Also
please pay attention to the BMW maintenance
system, refer to page235.
General driving notes
Closing luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is com-
pletely closed. Otherwise, exhaust fumes could
enter the interior of the vehicle.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Close all windows and the glass sunroof or
panorama glass sunroof.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page116.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, 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 property damage as well as
personal injury. 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 phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
