Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.
Also on the passenger side, do not incline the
backrest too far to the rear while the vehicle is
being driven, otherwise there is a danger in the
event of an accident of sliding under the safety
belt, eliminating the protection normally pro-
vided by the belt.<
Please observe the information on damage to
safety belts provided on page50 and the infor-
mation on the active front
head restraints* on
page49.
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page45.<

Adjusting lumbar support*
You can also adjust the contour of the backrest
to obtain additional support in the lumbar
region.
The upper hips and spinal column receive sup-
plementary support to help you maintain a
relaxed, upright sitting position.
>Increase or decrease curvature: press front
or rear section of switch.
>Shift curvature up or down: press upper or
lowers section of switch.
Adjusting active backrest width*
First set a comfortable backrest width, see
above. Based on the backrest width set, the lat-
eral support is automatically adapted to the cur-
rent driving situation.
The adaptation of the backrest width and the
speed of the adjustment vary depending on the
program. You can select from among three pro-
grams from comfort to sport.
Press button once per program:
>"Comfort" program: one LED
>"Normal" program: two LEDs
>"Sport" program: three LEDs
To switch off: press button longer.
Easy entry/exit*
To facilitate entry and exit, the backrest width
temporarily opens all the way.
Seat, mirror and steering
wheel memory*
You can store and request two different posi-
tions for the driver's seat and passenger seat
*,
exterior rearview mirrors, and steering wheel.
The adjustment of the lumbar support is not
stored in the memory.
Storing
1.Switch on radio readiness or ignition, refer
to page59.
2.Set the desired seat, exterior mirror and
steering wheel positions.
3.Press the button:
The LED in the button lights up.
4.Press the desired memory button1 or2:
The LED goes out.
Requesting
Do not request a position from the mem-
ory while the vehicle is moving. There is a
risk of accident from unexpected movement of
the seat or steering wheel.<
Comfort mode
1.Open the driver's door after unlocking or
switch on radio readiness.
2.Briefly press the desired memory button1
or2.

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and other persons, e.g. by opening
the doors.<
Children always in the rear
Accident research shows that the safest place
for children is on the rear seat.
Children younger than 13 years of age or
with a height under 5 ft/150 cm may only
be transported in the rear in child restraint sys-
tems which correspond to the age, weight and
height of the child. Otherwise there is an
increased danger of injury in an accident.<
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
system can no longer be used due to their age,
size and weight.
With the exception of the driver's seat, all seats
in your BMW comply with the recommenda-
tions of the standard SAE J1819 for the safe
securing of child restraint systems in motor
vehicles.
Exception for front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front and side airbags on the passen-
ger side must be deactivated. Otherwise, there
is an increased risk of injury for the child if the
airbags are triggered, even with a child restraint
system. Your BMW center will be glad to advise
you.<
For more information on automatic deactivation
of the front passenger airbags, refer to page97.
Installing child restraint
systems
Observe the child restraint system manu-
facturer's instructions for selection,
installation and use of the child restraint sys-
tems. Otherwise the degree of protection may
be reduced.<
Backrest width* on front passenger
seat
Before mounting a child restraint system
on the front passenger seat, the backrest
width adjustment must be open completely.
After mounting the child's seat, no memory
position may be called up and the active back-
rest width adjustment must be deactivated,
otherwise the stability of the child's seat on the
front passenger seat is limited.<
1.After unlocking the vehicle, sit on the front
passenger seat and close the door to call up
the memory position.
2.Completely open the backrest width adjust-
ment, refer to page46.
3.Deactivate active backrest width adjust-
ment, refer to page47.
4.Install child's seat.
Child seat security
All rear safety belts and the safety belt for the
front passenger can be locked against pulling
out to secure child restraint systems.

Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT... 3406 indicates that the
tire was manufactured in week 34 of 2006.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
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
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service practices and differences in road characteris-
tics and climate.
Traction
The 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 specified government test sur-
faces 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, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
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 car
tires must meet under the Federal Motor Vehi-
cle 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 excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page213. e.g.
