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 a major loss in tire infla-
tion pressure.
>The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steering
maneuvers. Do not exceed a speed of 50 mph/
80 km/h.
If the vehicle is not equipped with run-flat
tires as provided at the factory, refer to
page249, do not continue driving. Continuing
to drive with a flat tire could cause severe acci-
dents.<
Continued driving with a flat tire
Possible driving distance with complete loss of
tire inflation pressure:
>With a light load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or
4 persons without luggage:
Approx. 95 miles/150 km
>With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km
Drive reservedly 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.
reduced lane stability during braking, a longer
braking distance and altered self-steering prop-
erties.<
Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces
of the tire could come loose and cause an acci-dent. Do not continue driving, and contact your
BMW Sports Activity Vehicle Center.<
Message when not reset
The yellow warning lamp lights up. A
message appears on the Control Dis-
play.
The system is not reset, e.g. after a wheel
change.
Check the tire inflation pressure and reset the
system, refer to page102.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are displayed in gray on the Control
Display. No flat tire can be detected.
Display in the following situations:
>Malfunction:
Have the system checked
>If a wheel without TPM electronics is
mounted, e.g. a compact wheel
*
>Interference due to systems or devices that
use the same radio frequency:
The system automatically reactivates once
it is outside of the field of interference.
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

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
page100, or reset the Tire Pressure Monitor,
refer to page102.<
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. 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. Oth-
erwise tire damage and accidents could
occur.<

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 page100
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure
page103
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

Wheels and tires
250 Tire Pressure Monitor cannot detect a flat tire,
refer to page101. 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
page96.<

Replacing components
270 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 area.
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
page100, or reset the Tire Pressure Moni-
tor, refer to page102.
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. 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.
Replacing battery
Only use vehicle batteries that have been
approved for your vehicle by the manu-
facturer; otherwise, the vehicle could be dam-
aged and systems or functions may not be fully
available.<
After a battery replacement, have the battery
registered on the vehicle by your BMW Sports
Activity Vehicle Center to ensure that all com-
fort functions are fully available.
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 page274.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a recycling cen-
ter. Maintain the battery in an upright position
for transport and storage. Always restrain the
battery to prevent it from tipping over during
transport.<
Power failure
Following a temporary power failure, e.g. due to
a discharged battery, the use of some equip-
ment will be restricted, requiring its reinitializa-
