Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.
Operating principle, refer to page 62.
1.Start the engine immediately before pulling
away, but do not drive off yet.2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the appro‐
priate symbol appears in the display, ac‐
companied by the word "RESET".3.Press button 2 to confirm your choice of the
Flat Tire Monitor.4.Press button 2 for approx. 5 seconds until
the display appears:5.Drive away.
Initialization is completed while the car is on
the move without providing feedback.
Indication of a flat tire
The warning lamps come on in yellow
and red. In addition, a signal sounds.
There is a flat tire or a major loss in tire
inflation pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 161, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.Seite 76ControlsSafety76
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the
system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀
Tire Pressure Monitor TPM
The concept
TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla‐
tion pressures are correct.
Always use wheels with TPM electronics. Oth‐
erwise, the system may malfunction.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flatSeite 77SafetyControls77
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

in spite of the fact that the tire is filled to the cor‐
rect inflation pressure.
The system is deactivated and is unable to de‐
tect flat tires if a wheel not equipped with TPM
electronics has been mounted, e.g., a compact
wheel, or if TPM is experiencing temporary in‐
terference from other systems or devices that
use the same frequency.
Resetting the system
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
Operating principle, refer to page 62.1.Start the engine, but do not start driving.2.Lightly push button 1 in the turn indicator
lever up or down repeatedly until the appro‐
priate symbol appears in the display, ac‐
companied by the word "RESET".3.Press button 2 to confirm your choice of the
Tire Pressure Monitor.
The following display appears:4.Press button 2 for approx. 5 seconds until
the small warning lamp lights up yellow and
the following display appears:5.Drive away.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the
target values to be monitored. The system
reset is completed during your drive, and
can be interrupted at any time. When driving
resumes, the reset is continued automati‐
cally. The indicator lamp goes out after the
system reset is completed.
Low tire pressure message
The warning lamps come on in yellow
and red. In addition, a signal sounds.
▷There is a flat tire or a major loss in
tire inflation pressure.▷The system was not reset after a wheel
change and thus issues warnings based on
the inflation pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires , refer to page 160, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.Seite 78ControlsSafety78

your service center.▷TPM could not be fully reset. Reset the sys‐
tem again.
The small warning lamp flashes in yel‐
low and then lights up continuously;
the larger warning lamp comes on in
yellow. No flat tire can be detected.

Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended 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 inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly 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 pres‐
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi‐
ciency and tire tread life, and may affect the ve‐
hicle's handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re‐
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres‐
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups 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 in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement 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 re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Brake force display
The concept▷During normal brake application, the brake
lamps light up.▷During heavy brake application, the turn sig‐
nals light up in addition.
The brake force display is not activated if the
turn signal function is switched on.

Tire inflation pressure
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
Checking the pressure
Only check the 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 the tires
are warm, the tire inflation pressure is higher.
After correcting the tire inflation pressure, rein‐
itialize the Flat Tire Monitor, refer to page 75.
After correcting the tire inflation pressure, reset
the Tire Pressure Monitor, refer to page 78.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
approved and tire brands recommended by
BMW; a list of these is available from your serv‐
ice center.
For correct identification of the right tire inflation
pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h, ad‐
just pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be found
on the driver's side door pillar when the driver's
door is open.
Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀
