The rear backrest is divided into two
sections (one-third and two-thirds of the
width of the seat). For carrying longer
objects, you can fold down either
section of the backrest separately.
To unlock, pull the lever corresponding
to the section (arrow).460de154
The rear backrest section will move
forward slightly when it is unlocked.
Reach into the gap and pull the back-
rest down.
When you close the backrest, be
sure that the retainer engages
correctly. If it is not correctly engaged,
transported cargo could enter the pas-
senger compartment from the luggage
compartment during brake applications
or evasive maneuvers and endanger the
vehicle occupants.<460de153
The fittings at the corners of the lug-
gage compartment provide you with a
convenient means of attaching luggage
nets
* and flexible straps for securing
suitcases and luggage.

To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. BMW tests and approves
wheel/tire combinations. Refer to
page 118.

All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1 1/2) times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
TractionThe traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of as-
phalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering, hy-
droplaning, or peak traction character-
istics. highest), B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C correspods to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or ex-
cessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure. plicable on the tire sidewall between

Wheel and tire combinations The right choice Use only BMW-approved tires. Refer to
page 118.
Due to the high speeds this vehicle can
reach, the use of specific brands, spec-
ifications and sizes is mandatory. Con-
sult any BMW center for details. Com-
ply with local/national regulations.
The correct wheel-tire combina-
tion affects different systems such
as ABS, ATC and DSC. The function of
these systems is impaired if improper
wheel-tire combinations are used.
For this reason, use only tires of the
same brand and tread pattern. In the
event of a flat tire, for example, remount
the approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
The codes on radial tires:
The speed rating indicates the approved
maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = above 167 mph (270 km/h)
ZR = above 150 mph (240 km/h) Example:
Nominal width
in mm
Aspect ratio in %
Radial tire ID code
Rim diameter in inches
Load rating

Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect tire valve from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks. Example:
