Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Run-flat tires*
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible to
a restricted degree.
If you switch from summer to winter
tires, or vice versa, use run-flat tires,
as in the event of a breakdown there is no
spare wheel available. In this case, BMW
recommends that you consult your BMW
center. Your BMW center is qualified to
handle run-flat tires and equipped with the
necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue,
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h.
In the case of complete inflation pressure
loss, 0 psi/kPa, or obvious tire damage,
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values:
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. With
inflation pressure loss, the driving charac-
teristics change, for example reduced track
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.<
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
These snow chains are approved exclu-
sively for use in pairs on the rear wheels,
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe
the manufacturer's instructions when
installing snow chains.Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page 93.<

Run-flat tires*
You will recognize run-flat tires by a circu-
lar symbol containing the letters RSC on
the side of the tire. They consist of self-
contained tires and special rims. The tire
reinforcement ensures that the tire retains
some residual safety in the event of pres-
sure drop and driving remains possible
to a restricted degree. The vehicle is
equipped with a Flat Tire Monitor which
indicates punctures.
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
Flat tire
If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
You can find more detailed information on
the Flat Tire Monitor on page 95.
Reduce vehicle speed carefully to under
50 mph/80 km/h, avoiding hard brake
applications and steering maneuvers.
If the defective wheel is not recognizable
as such immediately, check the inflation
pressure in all four tires.
For reasons of safety, do not arrange
for run-flat tires to be repaired. Your
BMW center has the information needed
for working with these tires and is equipped
with the necessary special tools.<
Continuing driving with a damaged
tire
Driving on run-flat tires can continue
depending on the vehicle load and the
severity of the tire damage, at a maximum
speed of 50 mph/80 km/h. You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:
>Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles/
150 km
With full payload approx. 30 miles/
50 km
>Tire inflation pressure 7 psi/50 kPa to
15 psi/100 kPa:
Approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
Approx. 600 miles/1,000 km.
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the case
of air loss, you can expect changes in vehi-
cle handling such as reduced lane stability,
longer braking distances, and changes in
self-steering properties.<
Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
For all questions that regard the bat-
tery, please consult your BMW cen-
ter.<
Charging the battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page 208.
