Things to rememb er when driving
Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehicle, for example due to
the special 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 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 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 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.

Things to remember when driving
Driving tips
Check tire inflation pressure regularly
Check the tire inflation pressure at least twice a
month and before embarkin
g 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 between you and the 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, 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.
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 Mainte-
nance System, refer to page 260.
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
page 116.
3. Drive cautiously.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-

Refueling
Mobility
Coupe
1.
Remove the cover from the right-hand side-
wall of the trunk.
2. Pull the knob with the fuel pump symbol.
The fuel filler flap is released.
Convertible
1.Loosen the right-hand trunk trim panel by
turning the screws by 90°, see arrow.
2. Slightly lift the top section of the panel. It is
not necessary to remove the entire panel.
3. Pull the knob with the fuel pump symbol.
The fuel filler flap is released.
Observe the following when refueling
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid lifting the filler
nozzle while filling the tank, as that would lead
to
>Premature pump shutoff
> Reduced efficiency of the fuel-vapor recov-
ery system.
The fuel tank is full when the filler nozzle clicks
off the first time. Do not overfill the fuel tank; otherwise,
fuel spills can cause damage to the envi-
ronment and the vehicle. <
When handling fuels, follow the safety
instructions provided at filling stations;
otherwise, there is a risk of personal injury or
property damage. <
Fuel tank capacity
Approx. 16.1 US gal/61 liters, including the
reserve capacity of 2.1 US gal/8 liters.
Fuel specifications
Gasoline
For optimum fuel consumption, the gasoline
should be sulfur-free or as low in sulfur as pos-
sible.
Never use fuels labeled at the fuel pump as
metal-containing.
Do not use leaded gasoline or gasoline
with metal-containing additives such as
manganese or iron; doing so can cause perma-
nent damage to the catalytic converter or other
components. <
Use fuels with a maximum ethanol content of
10 Ξ, i.e. E10.
The ethanol should meet the following quality
standards:
US: ASTM 4806-xx
CAN: CGSB-3.511-xx
xx: comply with the currently valid standard. Do not fill the tank with E85, i.e. fuel con-
taining 85 Ξ ethanol, nor with FlexFuel.
Otherwise, the engine and fuel supply system
will be damaged. <
The engine has a knock control function. It is
therefore possible to use different fuel grades.
Recommended fuel grade
BMW recommends AKI 91.

MobilityEngine compartment
Hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are not familiar with the regulations to be
followed, have the necessary work on the vehi-
cle carried out only by your BMW center; if this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. <
Releasing
Pull the lever.
Opening
In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the hood. Do not open the
engine hood before the engine has cooled
down; otherwise, injuries may result. <
Press the release handle and open the hood.
Closing
Let the hood drop from a height of approx. 10 in/
25 cm. It must be clearly heard to engage. Make sure that the closing path of the
hood is clear; otherwise, injuries may
result.
If you see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely. <
Engine oil
General information
The engine oil consumption is dependent on
driving style and operating conditions; for
example, the engine oil consumption is signifi-
cantly higher with a very sporty driving style.
For this reason, regularly check the oil level
after each time you refuel.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.2 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
