The status is displayed.
Malfunction
The yellow warning lamp 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 wheel without TPM electronics is
mounted, e.g. a compact wheel
*
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency
Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation 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 underinflated. 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 underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping 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 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
approximately one minute and then remain con-
tinuously illuminated. This sequence will con-
tinue upon subsequent vehicle startups as long
as the malfunction exists. When the malfunc-
tion indicator is illuminated, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement 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
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
The active steering actively varies the steering
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies
the steering force required for steering depend-
ing on the vehicle's speed.
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

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. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect 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 acci-
dent. Do not drive with depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously 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
page93, or reset the Tire Pressure Monitor,
refer to page94.<
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 Sports Activ-
ity Vehicle Center.<For correct identification of the right tire infla-
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. of
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.
Otherwise tire damage and accidents could
occur.<

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 letter
Q = up to 100 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 US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT ... 0809 indicates that the
tire was manufactured in week 8 of 2009.
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 government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those 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.<

Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire page93
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure page95
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-
age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly different tire casing structures and the often
wide variations in their age, which can result in a
limited service life.<
The right wheels and tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. Your
BMW Sports Activity Vehicle Center will be
happy to advise you.
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.<
When changing to larger wheels and tires,
it may be necessary to make changes to
the wheelwell trim piece, as otherwise road
users could be endangered or the vehicle could
be damaged. Only have this work carried out by
a BMW Sports Activity Vehicle Center or a
workshop that works in accordance with BMW
guidelines and uses appropriately trained per-
sonnel.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel/tire combination.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC, xDrive,
Dynamic Performance Control in the BMW X6,
or Flat Tire Monitor.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.

Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
Tire Pressure Monitor cannot detect a flat tire,
refer to page94. Your BMW Sports Activity
Vehicle Center will be happy to advise you on
this subject.
Recommended tire brands
Certain tire makes are recommended by BMW
depending on the tire size. You can recognize
these from the clearly visible BMW marking on
the tire sidewall.
When used properly, these tires comply with
the most demanding standards for safety and
vehicle response.
Special characteristics of winter tires
BMW recommends using winter tires for opera-
tion on winter road or at temperatures below
+457/+76. Although all-season M+S tires
provide better winter traction than summer
tires, they generally fail to provide the same lev-
els of cold-weather performance as winter tires.
Paying attention to speed
Always observe the maximum permissi-
ble speed for the winter tires, otherwise
tire damage may occur, which can result in acci-
dents.<
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
Even with tires of the same size, BMW
recommends that you not rotate the front
tires to the rear or vice versa as this can nega-
tively affect handling characteristics.
When the vehicle is equipped with different
tires sizes
*, rotating tires from one axle to the
other is not permitted.<
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Your BMW Sports Activity Vehicle Center
can provide you with this information.
BMW X5: use is only permitted in pairs on the
rear wheels with tires of the size:
>255/55 R 18
>255/50 R 19
BMW X6: it is only permissible to use snow
chains in pairs, on the 255/50 R 19 rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor
*, as otherwise
incorrect displays can occur.
When you are driving with snow chains, it can
be beneficial to activate DTC briefly, refer to
page89.<

Replacing components
258 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 speci-
fied torque. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 101 lb ft/140 Nm.<
2.Stow the defective wheel in the cargo bay.
The defective wheel cannot be stored
under the floor panel flap due to its
size.<3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page93, or reset the Tire Pressure Monitor,
refer to page94.
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. Otherwise,
changes in the driving characteristics could
result, 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 charac-
teristics are more pronounced.<
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
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 Sports Activity Vehicle 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 switched off. Connections, refer to
Jump starting on page262.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
