The units of measure can be set.
Setting the units of measure
You can change the units for fuel consumption,
route/distance, temperature and pressure.
1."Settings"
2."Language/Units"
3.Select the desired menu item.
4.Select the desired unit.
The settings are stored for the remote control
currently in use.
Service requirements
The remaining driving distance and the date of
the next scheduled service are displayed briefly
immediately after you start the engine or switch
on the ignition.
The extent of service work required can
be read out from the remote control by
your BMW Service Advisor.<
For certain maintenance operations, you can
view the respective distance remaining or due
date individually in the instrument cluster.1.Switch on the ignition, refer to page55.
2.Push button 1 in the turn signal/high beam
lever up or down repeatedly until the appro-
priate symbol appears in the display,
accompanied by the words "SERVICE-
INFO".
3.Press button2.
4.Use button 1 to scroll through the individual
service items.

Message for unsuccessful system
reset
Yellow warning lamp comes on. A
message appears on the Control Dis-
play.
The system is not reset, e.g. after a wheel
change.
Check the tire inflation pressure and reset the
system, refer to page85.
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp comes
on in yellow.The tires appear in gray
in the Control Display. No punctures can be
detected.
Display in the following situations:
>Malfunction:
Have the system checked
>A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
>Interference from systems or devices that
use the same radio frequency:
The system automatically becomes active
again when the vehicle moves out of the
interference zone.
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 under-inflated. 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 indicator.
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 lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, 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 road speed
range, e.g. in a town or when parking, the steer-
ing angle is increased, i.e. steering becomes
very direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.

Things to remember when driving
112
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 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.
Check tire inflation pressure regularly
Check the tire inflation pressure 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 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.
