Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
telltale when one or more of your tires are signif-
icantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator lights up, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low speed range,
e. g. in a town or when parking, the steering
angle increases, i.e. the steering becomes very
direct. In the higher speed range, on the other
hand, the steering angle is reduced more and
more. This improves the handling capability of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page83.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Control Dis-
play. Active steering is malfunctioning
or is temporarily deactivated. At low speed,
larger steering wheel movements are required,
while the vehicle reacts more sensitively to
steering wheel movements in the higher road
speed range. The stability-promoting interven-
tion can also be deactivated. Proceed cau-
tiously and drive defensively.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature

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 kickdown 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 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 the 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 the cooling function of the
automatic climate control, seat heating or rear
window defroster draw large amounts of power
and consume additional fuel. Their influence is
particularly pronounced in city and stop-and-go
traffic. 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 page206.
General driving notes
Closing luggage compartment lid
Only drive with the luggage compartment
lid completely closed, otherwise exhaust
can penetrate into the passenger compart-
ment.<
If it is absolutely necessary to drive with the lug-
gage compartment lid open:
1.Coupe: close both windows and the glass
sunroof.
Convertible: with closed top, close all win-
dows.
2.Increase the air volume of the automatic cli-
mate control to a high level, refer to
page105.
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
