Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
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,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency 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 under-inflation has
not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure 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.Brake force display

Wheels and tires
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 if necessary, including on the
spare wheel
*: 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 a depressurized, i.e. flat, tire. 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
page83, or reset the Tire Pressure Monitor,
refer to page85.<
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.<

suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there. Tire damage can
be extremely dangerous for vehicle occupants
and other road users.<
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards. Make sure that the new wheels are bal-
anced.<
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
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. When selecting the tires, also ensure
that they have a sufficient load-carrying capac-
ity. If non-approved wheels and tires are used,
BMW cannot evaluate their suitability, and
therefore cannot be held liable for driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct wheel/tire combination also affects
various systems whose function would other-
wise be impaired, e.g. ABS or DSC.
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 converting from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the

Wheels and tires
198 Tire Pressure Monitor cannot detect a flat tire,
refer to page84. Your BMW 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 winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay 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.<
After changing wheels/tires
After changing tires or wheels, the slip detec-
tion of the Sequential Manual Transmission
must become familiar with the changed state.
Reinitialize the system for this purpose:
1.Move the selector lever into the idling
position N on a straight stretch of road at
a speed between 20 mph/30 km/h and
90 mph/150 km/h.2.Pull both shift paddles for approx. 2 sec-
onds.
If you do not carry out initialization, the system
will automatically learn the changed state grad-
ually during driving. This may be noticeable
from the clutch opening and closing briefly.
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
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permitted in pairs, with winter tires
of the size 245/45 R 18 on the 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.
Make sure that the snow chains are always suf-
ficiently tensioned. Retension in accordance
with the chain manufacturer's specifications if
necessary.
After mounting snow chains, do not ini-
tialize the Flat Tire Monitor, otherwise
incorrect displays can occur.
After mounting or removing snow chains, the
slip detection of the Sequential Manual Trans-
mission must become familiar with the altered
state. To do this, reinitialize the system, refer to
After changing wheels/tires.<

Replacing components
210 4.Screw dust cap off valve of defective wheel
and screw filling hose2 of sealant bottle
onto valve.
5.Insert sealant bottle on compressor hous-
ing so that it is positioned upright.
6.Make sure that the device is switched off,
position 0.
7.Insert connector3 into lighter socket in
vehicle interior, refer to page106.
8.With the ignition switched on:
Switch on the device and allow to run for
approx. 3 minutes to fill wheel with sealant.
It is not important what inflation pressure
the tire has after filling.
9.Switch off device.
10.Remove connecting hose from connection
of sealant bottle and tire valve.
Stow the M Mobility System in the vehicle
again.
Distributing sealant
Immediately drive approx. 2 miles/3 km so that
sealant is evenly distributed in tire.
Do not exceed a maximum speed of
35 mph/60 km/h. Do not drop below
12 mph/20 km/h if possible.<
Producing tire inflation pressure
1.After approx. 2 miles/3 km, stop at suitable
location.
2.Screw compressor hose9 directly onto tire
valve.
3.Insert connector 3 in lighter socket in vehi-
cle interior.4.Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>Increase inflation pressure: switch on
compressor, position I. To check cur-
rently set inflation pressure, briefly
switch off device.
Do not allow compressor to run
longer than 10 minutes, otherwise
the device will overheat and may be dam-
aged.<
>Reduce inflation pressure: press but-
ton8 or turn s crew8 on pressure gauge.
If the inflation pressure is not held, drive
the vehicle again, refer to Distributing
sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire damage from a size of approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page215, or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made ready for driving with the
M Mobility System.<
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise do not con-
tinue driving.<
Continue driving
Do not exceed the permissible maximum
speed of 50 mph/80 km/h, otherwise
accidents can occur.<
Reinitialize the Flat Tire Monitor.
For details, refer to page83.
Have the defective tire and the sealant bottle of
the M Mobility System replaced as soon as
possible.<
Changing wheels*
Safety precautions in the event of a flat
tire or wheel change: park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead set-
ting of the wheels. Apply the handbrake and
engage first gear or reverse gear with a manual

Replacing components
212 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 spare 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. The tightening torque is
88.5 lb ft/120 Nm.<
2.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve stem
seal caps against dirt and contamina-tion. Dirt in valve stems is a frequent source
of gradual air loss.<
3.Initialize the Flat Tire Monitor, refer to
page83, and the Sequential Manual Trans-
mission, refer to After changing wheels/
tires on page198.
4.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Stowing wheel and tools
1.Lay the wheel in the tool mounting.
2.Lay the cover on the mounting.
3.Center the wheel and cover relative to the
lashing eyes5.
4.Hook the belt into the lashing eyes.
5.Completely open the tensioning lock.
6.Thread the belt3 through the axis6 of the
tensioning lock without twisting it and ten-
sion it by hand.
7.Tighten the belt firmly with the tensioning
lock by opening and closing the lock several
times.
8.Fold the tensioning lock closed and stow
the protruding belt end.
Driving with spare wheel
With certain wheel-and-tire combinations
the size of the spare wheel differs from
that of the other wheels. The spare wheel is
equivalent to them in all load and speed ranges.
However, to restore the original state, the nor-
mal wheel should be remounted as soon as
possible.<
