2009 BMW 3 SERIES fuel consumption

Everything under control

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control Dis-
play.
Check coolant level, refer to page215.
Energy Control*
Displays the current fu el consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 210 7/1006 and approx. 300 7/
150 6.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 16.1 US gallons/
61 liters.
You can find information on refueling on
page 191.
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
Once the fuel level ha s fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
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. 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:
> Gasoline engine
4,500 rpm or 100 mph/160 km/h
> Diesel engine
3,500 rpm or 93 mph/150 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 no t achieve their full trac-
tion potential until afte r 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 distan ce 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 vehicle serviced regularly.
Remove any unneeded cargo
Additional weight incr eases 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.
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 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, accele rate without hesitation
or pauses. When accelerating, shift up before
reaching high engine speeds.
When you reach the desired 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 engi ne 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 a dditional 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 page 216.
General driving notes
Close the luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate and rear
window are closed. Otherwise, exhaust fumes
could enter the interior of the vehicle. <
If the vehicle must be driven with the luggage
compartment lid/tailgate 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 95.
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 sect ions of the exhaust sys-
tem, and never apply un dercoating 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 ho t exhaust tail pipes.
Otherwise there is a risk of burns. <
Diesel particulate filter*
The diesel particulate filter collects soot parti-
cles and burns them periodically at high tem-
peratures. This cleaning process takes several
minutes. During cleaning, you may notice that
the engine temporarily runs less smoothly and
that a somewhat higher engine speed is neces-
sary to achieve the accustomed performance.
Also, noises may be heard and a slight amount
