Malfunction in driving-stability control
systems
The warning lamp for the brake system
lights up yellow, together with the indi-
cator lamps for ABS, DSC and Tire
Pressure Monitor or Flat Tire Monitor.
A message appears on the Control Dis-
play. The driving-stability control sys-
tems have failed. While you may con-
tinue, you should remember to proceed
cautiously and drive defensively while
avoiding full brake applications. The
Tire Pressure Monitor or the Flat Tire Monitor is
also malfunctioning. Have the system checked
as soon as possible.

Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.
1.Hold the vehicle with the brake.
2.Release the brake and begin to drive imme-
diately.
After releasing the brake, begin to drive
immediately; otherwise, the starting
assistant no longer holds the vehicle after
approx. 2 seconds and your vehicle will start to
roll backward.<
Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.

Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
is shown on the Control Display. A mal-
function has occurred in the self-leveling sus-
pension. Stop and check the vehicle. If it is con-
siderably lower at the rear than at the front, and
possibly also on one side – rear left compared to
rear right –, go to the nearest BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
ably reduced. Even if the position of the vehicle
is normal, go to the nearest BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
In order to ensure that a flat tire is reported cor-
rectly, the system must be initialized while the
tires have the correct inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate sudden
severe tire damage caused by outside factors
and does not detect a natural, even pressure
drop in all four tires.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. The system is initialized
after this activation phase. When driving with
snow chains
*or a compact tire*, the system is
not initialized.<

Indication of a flat tire
The warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact a BMW center.<
3.Replace the damaged wheel, refer to
Changing wheels on page248.
Run-flat tires*
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid severe braking and steering
maneuvers and do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page229, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 94 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
50 mph/80 km/h or else you run the risk of
causing an accident. In the event of pressure
loss, vehicle handling changes. This includes
reduced tracking stability in braking, extended
braking distance and altered natural steering
characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact your BMW
center.<

TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset at the correct tire
inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious tire
damage caused by external influences.
The system does not function properly if it has
n o t b e e n r e s e t , e . g . a f l a t t i r e i s r e p o r t e d d e s p i t e
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, e.g. a compact wheel, or if TPM is
temporarily interfered with by other systems or
devices which use the same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" appears on the Control Display.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems or
devices which use the same radio fre-
quency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving, which can be
interrupted at any time. When driving resumes,
resetting is continued automatically. Do not
reset the system when driving with a compact
wheel

ing driving. The tires are shown in green on the
Control Display.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.<
Message with low tire inflation
pressure
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Check whether your vehicle is equipped
with standard tires or run-flat tires.
You will recognize run-flat tires by a
circular symbol containing the letters
RSC on the side of the tire, refer to
page229.<
Standard tires
1.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
2.Replace the damaged wheel or wheels,
refer to Changing wheels on page248.
In contrast to a compact wheel, a spare wheel is
equipped with the necessary TPM electronics
and also monitored after mounting and after
resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Run-flat tires*
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid severe braking and steering
maneuvers and do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page229, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<

Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheel is mounted without TPM elec-
tronics.
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly underin-
flated. 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 handling and stopping
ability. Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if underinflation has not reached
the level to trigger illumination 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
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes

Things to remember when driving

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 kick-down 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.

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. Otherwise driving instability
or tire damage, and therefore accidents, can
result from incorrect tire inflation pressures.
Do not drive with depressurized, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page95, or reset the Tire Pressure Monitor,
refer to page97.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW center.<
For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. 100 mph/
160 km/h to achieve optimum driving comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The maximum permissible speed for
these tire pressures is 100 mph/160 km/
h. Do not exceed this speed, otherwise tire
damage and accidents could occur.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please

for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages. Oth-
erwise tire damage and accidents could
occur.<
Observe all national and local maximum speed
limits, otherwise violations of the law could
occur.
