Roof-mounted luggage rack for the hardtop*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the covers, please use the
tool provided with the roof-rack system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
handling and steering response.
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the maximum axle loads
when loading the rack. These weights
are listed under Technical data on
page 168.
Make sure that the load is not too bulky,
and attempt to distribute it evenly.
Always load the heaviest pieces first so
that they are at the bottom. Make sure
that no objects will be in the way when
the luggage compartment lid is opening
or closing.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
The roof-mounted luggage rack and the
roof load increase the aerodynamic
resistance: increased fuel consumption
and additional stress on the vehicle's
body are the result.

Wheel and tire combinationsThe right choice
BMW recommends using only
wheels and tires that have been
approved by BMW for your particular
vehicle model, as otherwise body con-
tact and serious accidents can result
despite the use of the same nominal
size, e.g. due to manufacturing toler-
ances. BMW cannot evaluate all tires
and wheels on the market, and is thus
unable to guarantee that the vehicle will
continue to perform safely if unap-
proved tires and/or wheels are
mounted.<
For each tire size, BMW has assessed
the safe performance of specific tire
brands and approved them for use.
Consult any BMW center for details.
Comply with any local/national regula-
tions, for example by recording the tire
type in the vehicle documents.
The correct wheel and tire combi-
nation affects various systems
that would otherwise be impaired, for
example ABS, DSC and DBC.
For this reason, use only tires of the
same manufacture and tread configura-
tion. In the event of a flat tire, for exam-
ple, remount the approved wheel and
tire combination as soon as possible.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.
Do not exceed the maximum tire infla-
tion pressures specified on the tire
sidewall.
Winter tiresChoosing the right tireBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires – with
M+S designation – provide better winter
traction than the corresponding sum-
mer tires, they generally do not achieve
the performance of winter tires.
In the interest of safe tracking and
steering response, install winter tires
made by the same manufacturer and
with the same tread configuration on all
four wheels.
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by trained
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you. your BMW is eqipped with Run Flat
tires. These are indicated by a circular
symbol containing the letters RSC on

Washer fluidHeadlamp* and windshield
washer systemApproximate capacity is
5.6 US quarts/5.3 liters.
Fill with water and, if required, with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in closed
original containers, inaccessible to chil-
dren. Comply with the instructions on
the containers.<
Engine oilChecking the oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
