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, luggage compartment or
cargo area full, or 4 persons without
luggage:
approx. 94 miles/150 km
>With a full load:
from 4 persons, luggage compartment
or cargo area full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. 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 have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, as
otherwise 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 influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
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" is displayed on the Control Dis-
play.
A wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.

Technology for comfort, convenience and safety
92
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
*.
iDrive, for explanation of principle, refer to
page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.Select "TPM" and press the controller.
5.Start the engine, but do not start driving.
6.Select "Reset" and press the controller.7.Select "Yes" and press the controller.
8.Start to drive.
The tires are shown in gray and
"Resetting TPM..." is displayed.
After a few minutes of driving, the set tire infla-
tion pressures in the tires are applied as the set
values to be monitored. Resetting finishes dur-
ing driving. The tires are shown in gray on the
Control Display and "Status: TPM active" is dis-
played again.
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
page201.<

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 page215.
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 sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page201, do not
continue driving. Continuing to drive with a
flat tire could cause severe accidents.<
2.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, luggage compartment or
cargo area full, or 4 persons without
luggage:
approx. 95 miles/150 km
>With a full load:
from 4 persons, luggage compartment
or cargo area full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. 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.<
Malfunction
The yellow warning light 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 wheels is mounted without TPM elec-
tronics
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
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
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
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 simultaneously deactivated
when DSC is switched off, refer to page87.

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
page90, or reset the Tire Pressure Monitor,
refer to page92.<
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. 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 permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
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
observe, and, if necessary, adjust tire pressures
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.

face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the vehicle and remove the jack from
beneath the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the specified torque. The tightening torque is
88.5 lb ft/120 Nm.<
2.When stowing the wheel and tools in the
vehicle, execute these steps in the reverse
order.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as quickly as
possible.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page220.
