Drive defensively
Avoid unnecessary acceleration and braking
maneuvers. To do so, keep an adequate dis-
tance between you and the vehicle in front of
you. A defensive and smooth driving style
keeps fuel consumption down.
Avoid high engine speeds
Use first gear only for driving 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.
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 a
BMW center. Also note the BMW service sys-
tem, refer to page221.
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 air volume of the auto-
matic climate control system, refer to
page101.
3.Drive cautiously.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Do not remove the heat shields installed in
its vicinity, 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, 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

Have the vehicle checked immedi-
ately; otherwise, the excess oil may
lead to engine damage.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page74. Have the
system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until a
corresponding message is shown on the Con-
trol Display.
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
If the engine oil is too high, have the vehi-
cle checked immediately; failure to do so
may result in engine damage.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil grades to add
Do not use oil additives as this could
result in engine damage.<
When selecting an engine oil, make sure
to use one from the SAE viscosity classes
0W-40, 0W-30, 5W-40 or 5W-30; failure to do
so may result in malfunctions or engine dam-
age.<
The engine oil quality is critical for the life of the
engine.Some oil grades may not be available in all
countries.
Approved oil grades
Additional information about approved oil
grades is available at your BMW center.
Alternative oil types
If approved oils are not available, you can add
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
Oil change
Oil changes should only be performed by a
BMW center.
Coolant
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Coolant temperature
If the coolant and therefore the engine over-
heats, a warning lamp lights up. A message
appears on the Control Display.

Socket for Onboard
Diagnosis OBD
On the driver's side is an OBD socket for check-
ing components relevant to the composition of
the vehicle's emissions.
Emissions
The warning lamp lights up:
The vehicle is producing higher emis-
sions. The trip can be continued. Have
the car checked as soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under certain condi-
tions. This indicates excessive misfiring in the
engine. If this happens, you should reduce your
speed and visit your nearest BMW center as
soon as possible. Severe engine misfiring can
quickly lead to serious damage of emissions-
related components, especially the catalytic
converter.
The warning lamp comes on if the fuel
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. Make sure that the fuel cap is cor-
rectly positioned and close it until it audibly
clicks.
Data memory
Your vehicle records data about the operation,
faults, and user settings. These data are stored
in the vehicle and in extract form, in the remote
control, and can be read out using suitable
devices at your BMW center. The data that are
read out are used to support service proce-
dures and repairs or to optimize and expand
vehicle functions. If you have a BMW Assist
contract, certain vehicle data can also be trans-
mitted directly from the vehicle in order to
enable the desired services.

Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW center perform any work that you
do not feel competent to perform yourself or
that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW center.Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns.<
When working on electrical systems,
always begin by switching off the con-
sumer in question; otherwise, short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
If the routine for changing a particular
bulb is not described here, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light sources for many
of the controls and displays in your vehicle.
These light-emitting diodes, which operate
using a concept similar to that applied in con-
ventional lasers, are officially designated as
Class 1 light-emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation of the retina.<
Headlight lenses
In cool or humid weather, condensation may
form on the interior of outside lamps. When the
light is switched on, the condensation will dis-
appear after a short time. The headlamp
glasses do not need to be changed.
At high humidities, e.g. water droplets may form
in the lights; have these checked by your BMW
center.
Xenon lamps*
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon lamp fails never-
theless, switch on the fog lamps and continue
