Wheel changes on page108.
Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.<
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 cor-
rect inflation pressure.
The system is deactivated and is unable to
detect flat tires if a wheel not equipped with
TPM electronics has been mounted, e.g. a
compact wheel, or if TPM is experiencing tem-
porary interference from other systems or
devices that use the same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
1.Start engine, but do not begin to drive.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Wheel changes on page108.
4.Check tire inflation pressure and correct as
needed.

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 wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. 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 loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages53,
54.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve optimum driving com-
fort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages53, 54.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective 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.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. 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 soon as
possible.<
Vehicle battery
Maintenance
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 Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page114.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page30.
>Time
Must be set again, refer to page46.
