Wheels and tires
Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but
also driving comfort and driving safety that
largely depend on the condition of the tires
and the maintenance of the specified tire
pressure.
Check tire inflation pressures regu-
larly and correct them if necessary: at
least every two weeks and before every
extended journey. If this is not done, incor-
rect tire pressures can cause driving insta-
bility or tire damage, ultimately resulting in
accidents.
Do not drive with a deflated, i.e. flat, tire
unless your vehicle is equipped with Run
Flat tires. A flat tire greatly impairs steering
and braking response, and can lead to
complete loss of control over the vehicle.<
Checking tire pressures
Check the tire inflation pressures only
when the tires are cold. This means after a
maximum driving distance of 1.25 miles/
2 km or if the vehicle has been parked for at
least 2 hours. Warm tires have higher infla-
tion pressures.
Reinitialize the Flat Tire Monitor after cor-
recting the tire inflation pressure. Refer to
page 55.
Inflation pressures for original tires
The specified inflation pressures for tires at
ambient temperature are provided on the
placard on the B-pillar and are visible when
the driver's door is open.
Inflation pressures for other tire
sizes
The following tire inflation pressure tables
show the inflation pressures for the speci-
fied tire sizes at ambient temperature.
Reinitialize the Flat Tire Monitor after
correcting the tire inflation pressure.
Refer to page 55.<
Tire size
The inflation pressures in the table apply to
BMW-approved tire sizes and brands. Your
BMW center will be glad to supply this
information.

Wheels and tires
80
Run Flat tires
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Run Flat tires consist of self-support-
ing tires and special rims. The tire rein-
forcement ensures that driving remains
possible to a restricted degree in the event
of pressure drop or even if the tire is
deflated.
When mounting or replacing summer
tires with winter tires, or vice versa,
use Run Flat tires since no spare wheel is
available in the event of a flat. Your BMW
center knows how to work with Run Flat
tires and is equipped with the necessary
special tools.<
Driving with a damaged tire
When using Run Flat tires, you can con-
tinue driving cautiously at a maximum
speed of 50 mph / 80 km/h, depending on
the cargo load and the extent of tire dam-
age.
If there is a total loss of tire inflation pres-
sure, 0 psi/kilopascal, or obvious tire dam-
age, you can gauge the mileage for contin-
ued driving on the basis of the following
indications:
>With a light load:
1 person without luggage:
approx. 150 miles/250 km
>With a medium load:
1 person, luggage compartment full,
or
2 persons without luggage:
approx. 90 miles/150 km>With a full load:
2 persons, luggage compartment full:
approx. 30 miles/50 km
Drive cautiously. Do not exceed a
speed of 50 mph / 80 km/h. Be aware
that vehicle handling will be altered when
there is a loss in inflation pressure. Antici-
pate, e.g., reduced tracking during braking,
longer braking distances and changed
steering characteristics.
For safety reasons, BMW recommends not
to have Run Flat tires repaired if they are
damaged, but to consult your BMW center
in such cases.<
Snow chains*
Only certain types of snow chains have
been tested by BMW, classified as road-
safe and approved. Consult your BMW
center for more information. BMW recom-
mends using only approved fine-link snow
chains. Use them in pairs on either summer
or winter tires, but only on both rear
wheels.
Comply with all manufacturer's safety pre-
cautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.
Do not initialize the Flat Tire Monitor
after snow chains have been
mounted.
When driving with snow chains, it may be
useful to deactivate the DSC briefly. Refer
to page 53.<

Please contact a BMW center in case of a
malfunction.
License plate lamps
5 watt bulb
1.Push out the lamp with a suitable object
and remove it
2.Replace the bulb.
Snap the lamp back into place.
Changing a wheel
Run Flat tires
Your BMW is equipped with Run Flat tires.
Therefore, the wheel no longer has to be
changed immediately in the event of a loss
in inflation pressure.
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Refer to page 80.
BMW recommends that you consult your
BMW center if you wish to replace the tires
of your BMW, or change from summer to
winter tires or vice versa.
Your BMW center knows how to work with
Run Flat tires and is equipped with the nec-
essary special tools.
When mounting or replacing summer
tires with winter tires, or vice versa,
use only Run Flat tires since no spare
wheel is available in the event of a flat.<
Jacking points
The jacking points are located at the posi-
tions indicated in the illustration.
Your BMW center can provide you
with a suitable jack.<
Battery
Maintenance
The battery is completely maintenance-
free. This means that the original electro-
lyte will normally last for the service life of
the battery under moderate climatic condi-
tions.
Please consult your BMW center
whenever you have any questions
concerning the battery.<
Indicator lamp
The indicator lamp for the battery
charge current lights up:
The battery is no longer being
charged. The alternator drive belt is defec-
tive or there is a malfunction in the charging
circuit of the alternator. Please contact the
nearest BMW center.
If the drive belt is defective, pull over
and switch off the engine immediately
to prevent overheating and serious engine
damage.
If the onboard supply voltage drops to a
very low level, increased steering effort
may also be necessary.<
