The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.
Have the damaged tire replaced by your BMW
Sports Activity Vehicle Center or a workshop
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. Flat tires
cannot be detected.
Such a message is displayed in the following
situations:
>When a malfunction is occurring:
Have the system checked
>When a wheel without TPM electronics is
mounted, e.g. a compact wheel
>When TPM is experiencing temporary inter-
ference from other systems or devices that
use the same frequency
NHTSA/FMVSS-required explanation
of 138 Tire Pressure Monitoring
System
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,
then 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 pressure warning lamp
when one or more of your tires are significantly
under-inflated. When the low tire pressure
warning lamp lights up, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly underinflated tire causes the tire to over-
heat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Please note that the TPMS is not a
substitute 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 warning lamp.
The TPMS malfunction indicator is combined
with the low tire pressure warning lamp. When
the system detects a malfunction, the warning
lamp will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups 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 intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction warning lamp after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking
The brake lamps and the center brake lamp
light up.
>Heavy braking
The rear fog lamps light up as well.

seat from below. Otherwise, a correct analysis
of the seat cushion is not ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbag
indicates the functional status of the front and
side airbag on the passenger side depending on
whether or not the seat is occupied. By lighting
up, the indicator lamp indicates that the pas-
senger airbags deactivated.
>The indicator lamp lights up when a child
sitting as directed in a child restraint system
designed for this is detected.
The front and side airbags on the passenger
side are deactivated.
Most child seats are detected by the
system. It is particularly advisable to
use the child seats approved by NHTSA at
the time the vehicle was produced. After
installing a child's seat, make sure that the
indicator lamp for the front passenger air-
bags has illuminated. This indicates that the
system has detected the child's seat and
that the front passenger airbags have been
deactivated.<
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat. The front and side airbags for the pas-
senger are activated.
>The indicator lamp does not light up when
the seat is empty.
In this case, the front and side airbags for
the passenger are deactivated.
Operational readiness of airbag system
When the ignition key is moved into position 1,
the warning lamp lights up briefly, thus indicat-
ing the operational readiness of the entire air-
bag system and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not come on when the
ignition key is moved into position 1.
>The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs; otherwise,
there is a danger of the system failing to
respond in the expected manner to an impact
occurring within its normal response range.<

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.

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 2806 indicates that a tire was manufac-
tured in week 28 of the year 2006.BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half (1γ) times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices, and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g. 235/50 R 18 97 V

age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
Correct wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After tire
damage, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page54. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.
Changing wheels from one axle to
another
BMW does not recommend changing the front
wheels to the back or vice versa as this can
impair handling characteristics.

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.
