Tire inflation pressures If the driver's door is open, the infla-
tion pressures are also visible on the
door pillar. Inflation pressures are
indicated in psi (bar) with tires cold
(ambient temperature).
The inflation pressures apply to tires
from BMW-approved manufacturers;
your BMW Retailer will provide you
with this information. Higher pres-
sures may be required for tires from
other manufacturers.a
Periodically check the inflation
pressure Ð also of the spare tire Ð at
least twice each month and before
setting out on an extended trip. Failing
this, incorrect tire pressure may ren-
der the car unstable or cause tire
damage resulting in an accident.cSedan models

protection and can be opened and
closed simply and quickly by one
person.
Here are a few tips to ensure that you
have a lot of pleasure with your con-
vertible: It is advisable to close the top
when the vehicle is parked. The closed
convertible top not only protects the
passenger compartment from unfore-
seeable damage from the weather, it
also provides a certain degree of theft
protection.
Even with the top closed, it is always
advisable to keep valuables locked in
the luggage compartment.
Do not mount roof racks on the convert-
ible top.
Please contact your BMW Retailer for
suitable mounting equipment and other

neously, otherwise the windows may

*
The fully automatic convertible top per-
fectly combines extremely simple, com-
fortable operation with reliable protec-
tion from the elements. Here are a few
tips to ensure that you have years of
pleasure with your convertible:
It is advisable to close the top when the
vehicle is parked. The closed top not
only protects the passenger compart-
ment from unforeseen weather-related
damage, it also provides a certain
degree of theft protection. Even with
the top closed, it is always advisable to
keep valuables locked in the luggage
compartment.
Do not mount roof racks on the convert-
ible top. Please contact your BMW
Retailer for suitable mounting equip-
ment and other accessories.
To prevent damage, do not operate the
top at temperatures below 325F (0

To protect the battery, it is advisable to
operate the top with the engine running
when possible.
