Technology for driving comfort and safety
Controls
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the following situations:
> Interference from systems or devices that
use the same radio frequency:
The system automatica lly 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 infl ation 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 pres sure 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
t e l l t a l e w h e n o n e o r m o r e o f y o u r t i r e s a r e s i g n i f -
icantly underinflated. Accordingly, when the
low tire pressure telltal e illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underi nflated tire causes the
tire to overheat and ca n 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 pr essure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
The TPMS malfunction in dicator 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, includ
ing 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 depe nding 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 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 im proves the handling 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 stabilizing
intervention is simult aneously deactivated
when DSC is switched off, refer to page 91.

Things to remember when driving
Driving tips
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 between you and th e 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, accele rate without hesitation
or pauses. When accelera ting, shift up before
reaching high engine speeds.
When you reach the desi red 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 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
your BMW center. Also note the BMW service
system, refer to page 202.
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 air
conditioner or automatic climate control
system, refer to page 110 or113.
3. Drive cautiously.

MobilityWheels and tires
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for driving on
winter roads or at temperatures below +45 7/
+7 6. Although all-season M+S tires provide
better winter traction th an summer tires, they
generally fail to provide th e same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents. <
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels betwee n the axles is not per-
missible.
Run-flat tires
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-sup-
porting tire and a spec ial rim. The reinforce-
ment in the sidewalls en sures that the tire can
continue to be used su bject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to In dication of a flat tire, page 94.
Snow chains
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Fl at Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DT C temporarily, refer to
page 91.<
