4."Reset"5.Start the engine, but do not start driving.6.Start the system reset with "Reset".7.Drive away. The tires are shown in gray and
"Resetting TPM..." is displayed.
After a short trip at over 30 km/h, the set tire
inflation pressures are adopted as target val‐
ues. The system reset is completed as you
drive, and can be interrupted at any time.
When driving resumes, the reset is continued
automatically. On the Control Display, the tires
are shown in green and "TPM active" is dis‐
played again.
If a flat tire is detected while the system is re‐
setting and determining the inflation pres‐
sures, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.
Low tire pressure message The warning lights come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
▷There is a flat tire or a major loss in tire in‐
flation pressure.▷The system was not reset. The system
therefore issues warnings in case of devia‐
tions from the tire inflation pressures
stored last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 96, are la‐
beled 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.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
The use of tire sealant can damage the
TPM electronics. In this case, have the
electronics checked at the next opportu‐
nity and have them replaced if necessary.
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.Seite 96ControlsSafety96

If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset 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 de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending 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
properties.◀
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 continue driving, and contact your service
center.◀
Message when not reset
The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 95.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐ ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. On the Control Display, the
tires are shown in gray and a message ap‐
pears. No flat tire can be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.

Wheels and tiresVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
When using the features and systems descri‐
bed here, adhere to local regulations.
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 pres‐
sure and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect 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 Tires naturally lose pressure uniformly across
all four tires.
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.Tires warm up during driving and the tire infla‐
tion pressure increases as the temperature
rises. The tire inflation pressure specifications
apply to cold tires or tires at ambient tempera‐
ture.
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.
The values displayed by tire inflation stations
may be up to 0.1 bar, 2 psi too low.
For the Flat Tire Monitor: after adjusting the
tire inflation pressure to a new value, reinitialize
the Flat Tire Monitor, refer to page 92.
For the Tire Pressure Monitor: after adjusting
the tire inflation pressure to a new value, reset
the Tire Pressure Monitor, refer to page 95.
Pressure specifications The tables below provide all the correct infla‐
tion 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
service center.
For correct identification of the right tire infla‐
tion 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,
adjust 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.
