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 indicator lamp when
one or more of your tires are significantly
under-inflated. Accordingly, when the low tire
pressure indicator lamp comes on, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level to trigger illumi-
nation of the TPMS low tire pressure indicator
lamp.
The TPMS malfunction indicator is combined
with the low tire pressure indicator lamp. When
the system detects a malfunction, the indicator
lamp will flash for approximately one minute and
then remain continuously lit. 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 indicator lamp after replac-
ing 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 func-
tion properly.Brake force display

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, including the
spare wheel: at least twice a month and before
starting long trips. If you fail to take this precau-
tion, 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 acci-
dent. Do not drive with deflated, i.e. flat tires,
except run-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, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.<
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.<
For correct identification of the right inflation
pressure for your tires, pay attention to the fol-
lowing:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving
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 for traveling speeds up to a 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 driving
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
consult the relevant table on the following
pages and adjust tire pressures as necessary to
the specified pressures for speeds exceeding
100 mph/150 km/h. Otherwise, tire damage
and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the law could
occur.

ingly trained personnel. If necessary, have the
vehicle towed there.
Tire damage can be extremely dangerous for
vehicle occupants and other road users.<
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire.
The run-flat tires consist of special rims and
tires that are self-supporting to a limited
degree. The tire reinforcement 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:
>When equipped with Flat Tire Monitor, refer
to Indication of a flat tire on page91.
>When equipped with Tire Pressure Monitor,
refer to Low tire pressure message on
page93.
New wheels and tires
Only have new wheels and tires mounted
by a BMW center or a tire specialist that
works in accordance with BMW guidelines and
uses appropriately trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. Possible variations in the
design and the age – which could be substantial
– of the tire casing structures can lead to unusu-
ally rapid wear.<
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. 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 center for the right
wheel and tire combination.
The correct wheel and tire combination affects
various systems whose function would other-
wise be impaired, such as ABS or DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always remember to 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 over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise the
Tire Pressure Monitor may not be able to detect
a flat tire, refer to page91. Your BMW center
will be glad to advise you.

Recommended tire sizes and 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.
Run-flat tires
When installing new tires or when changing
from summer tires to winter tires or vice versa,
for your own safety, use run-flat tires. No spare
wheel is provided in the event of a flat. Your
BMW center will be glad to advise you.
For safety reasons, BMW recommends
that you not have damaged run-flat tires
repaired; they should be replaced.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although so-called
all-season M+S tires provide better winter trac-
tion than summer tires, they generally fail to
provide the same levels of cold-weather perfor-
mance as winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Always store wheels or 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 pres-
sure indicated on the side wall of the tire.
Wheel changing between axles
BMW does not recommend changing the front
wheels to the rear or vice versa as this can dam-
age handling characteristics.
Snow chains*
Only certain fine-link snow chains are tested,
classified as road-safe, and recommended by
BMW. Consult your BMW center for more infor-
mation. Use on winter tires is only permissible in
pairs on the rear wheels. Follow the manufac-
turer's instructions when installing snow
chains. Do not exceed 30 mph/50 km/h with the
chains mounted.
Do not initialize the Flat Tire Monitor after
mounting snow chains. When you are
driving with snow chains, it can be beneficial to
activate DTC briefly, refer to page88.<

2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up the jack, refer to section of illustration.
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. Clean the lug bolts.
3.Position the new wheel or spare tire on the
hub and screw in at least two bolts diago-
nally.
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
100lbft/140Nm.<
2.Reverse the removal sequence when stor-
ing the wheel and tools in the vehicle.3.Check and correct the tire inflation pressure
at the earliest opportunity.
Use valve stem seal caps to protect
valve stems from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with spare tire
On certain wheel-tire combinations, the
size of the spare tire differs from that of
the rest of the tires. The spare tire is fully capa-
ble of running in all load and speed ranges.
However, to recreate the original conditions,
the tire should be replaced as soon as possi-
ble.<
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 center will be happy to advise
you on all questions concerning the battery.
Charging battery
Charge the battery in the vehicle only via the
terminals in the engine compartment and with
the engine off. Connections, refer to Jump
starting on page220.
