Seat adjustmentLumbar support
*
You can adjust the backrest's contour
for additional support in the curvature
of your spine's lumbar region.
The upper hips and spinal column
receive supplementary support to help
you maintain a relaxed, upright posture.
>Increase/decrease curvature:
Press the front/rear end of the switch
>Increase the upper/lower curvature:
Press the upper/lower end of the
switch.
Adjusting the width of the
backrests
*
The backrest width can be changed
with the sides to adjust the side support
to your individual needs.
Decreasing/increasing the width of the
backrest: press the front/rear end of the
switch.

Seat and mirror memoryYou can store and recall three different
driver's seat and outside mirror posi-
tions. The illustration shows the buttons
located on the side of the seat.
The memory will not retain the
adjustments made to the lumbar
supports or the width of the back-
rests.<
If you press the
M
EMORY button acci-
dentally: press the button again; the
indicator lamp goes out.
To store1 Turn the key to ignition key position
1 or 2
2 Adjust your seat and outside mirrors
to the desired position
3 Press the
M
EMORY button: the indi-
cator lamp in the button lights up
4 Press memory button 1, 2 or 3, as
desired: indicator lamp goes out.
To select a stored setting
Do not select a memory position
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected seat movement.<
Convenience function:
1 The driver's door remains open after
unlocking or the ignition key is in
position 1
2 Briefly press memory button 1, 2 or 3,
as desired.
Movement stops immediately when
one of the seat-adjustment or
memory buttons is activated during
the adjustment process.
Security function:
1 The driver's door is closed and the
ignition key is either removed or in
position 0 or 2
2 Maintain pressure on the desired
memory button 1, 2 or 3, until the
adjustment process is completed.
Your can have your vehicle's
systems adjusted in such a
manner that your personalized settings
are automatically set for the seat and
outside mirror positions when you
unlock the vehicle with your personal
remote control.<
If you make use of this method of
adjustment, be sure that the foot-
well behind the driver's seat is unob-
structed before unlocking the vehicle. If
you fail to do so, any persons or objects
behind the seat could be injured or
damaged by a rearward movement of
the seat.<

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 116.
DOT Quality Grades Treadwear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades.< Tread wearThe tread wear grade is a comparative
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 g) 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
asphalt 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,
aquaplaning, or peak traction charac-
teristics.< TemperatureThe temperature grades are A (the
highest), B, and C, representing the
tireÕs 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
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger vehicle 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, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.<< < <
Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200 Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired by
their use. This is due to the possible
variations in casing structures and, in
some cases, to their extreme age,
factors that can lead to a decrease in
their durability.<

Wheel and tire combinations The right choice Use only wheels and tires approved by
BMW for the corresponding vehicle
model, as otherwise the tires may make
contact with the body as the result of
tolerances despite the same nominal
size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
For wheel and tire specifications
approved by BMW, refer to page 116.
The correct wheel-tire combina-
tion affects different systems that
otherwise will not function properly,
e.g. ABS, DSC.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel-tire combination
following a flat tire as soon as
possible.<
Codes on tires and wheels The code on tires has the following
meaning.
Codes on radial tires:
The speed rating indicates the
approved maximum speed for the tire.
Summer tires:
S = up to112 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 = up to 187 mph (300 km/h)
ZR= over 150 mph (240 km/h) e.g.
Nominal width
in mm
Aspect
ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
225/45 R
1892W
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 on light-alloy wheels:
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valves frequently leads to slow
leaks. Storage Store tires in a cool, dry place,
protecting them against light when-
ever possible. Protect the tires against
contact with oil, grease and fuel. e.g.
