Roof-mounted luggage rackA special roof-rack system is available
for your coupe as an optional acces-
sory. Please comply with the precau-
tions included with the installation
instructions.
Roof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
have 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 axle loads when loading
the rack. You will find the specifications
for this under "Technical Data" on
page 172.
Make sure that the load is not too large
in size, and distribute it evenly. Always
load the heaviest pieces first (on the
bottom). Be sure that adequate clear-
ance is maintained for raising the
sunroof, and that objects do not project
into the opening path of the luggage
compartment lid.Secure the roof luggage correctly
and securely to prevent it from
shifting or being lost during driving
(danger to following traffic).<
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.

Special features of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While so-called all season tires (M+S
designation) provide better winter trac-
tion than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufac-
turer and which have the same tread
configuration at all four wheels.Comply with recommended speed
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 skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.BMW narrow-link snow chains are
intended for mounting in pairs at the
rear wheels only. Comply with all manu-
facturer's safety precautions when
mounting the chains. Do not exceed a
speed of 30 mph (50 km/h) while
driving with mounted snow chains.
