ingly.
Head restraints
A correctly adjusted head restraint reduces the
risk of neck injury in the event of an accident.
Adjust the head restraint in such a way
that its center is at approx. ear level. Oth-
erwise, there is an increased risk of injury in the
event of an accident. Only remove a head
restraint if no one will be sitting on the seat in
question. Reinstall the head restraint before
transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<

Adjustments
50 not fastened, if heavy objects are placed on the
front passenger seat, or if driver or front pas-
senger unfasten their safety belts.
Damage to safety belts
If the safety belts are damaged or
stressed in an accident: have the belt sys-
tem, including any belt tensioners or child-
restraint systems, replaced and the belt
anchors checked. Have this work done only by
your BMW center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, it is
not guaranteed that the safety devices will func-
tion properly.<
Mirrors
Exterior mirrors
The front passenger's mirror is more convex
than the driver's mirror. The objects seen in the
mirror are closer than they appear. Do not
gauge your distance from traffic behind you on
the basis of what you see in the mirror; other-
wise there is an increased risk of an accident.<

3Folding mirrors in and out*
The settings for the exterior mirrors are stored
for the remote control currently in use
*, refer to
Personal Profile, page28. The stored positions
are called up automatically when the vehicle is
unlocked.
Manual adjustment
The mirrors can also be adjusted manually:
press the edge of the glass.
Folding mirrors in and out*
At driving speeds up to approx. 12 mph/
20 km/h, you can fold the mirrors in and out by
pressing button3. This can be beneficial in nar-
row streets, for example, or for moving mirrors
that were folded in by hand back out into their
correct positions. Mirrors that were folded in are
folded out automatically at a speed of approx.
25 mph/40 km/h.
Before entering an automatic car wash,
fold in the exterior mirrors by hand or with
button3, to prevent them from being damaged
due to the width of the vehicle.<
Automatic heating*
At outside temperatures below a certain limit,
both exterior mirrors are automatically heated
while the engine is running or the ignition
switched on.

lever to position R.
The glass of the mirror on the passenger
side tilts slightly down. This allows the
driver to see the area immediately adjacent
to the vehicle, e.g. a curb, when backing into
a parking space.

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle, otherwise they could endanger
themselves and/or other persons by opening
the doors, for example.<
The rear center seat is not suitable for installing
universal child-restraint systems for all age
groups, approved for the age group in question.
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child-restraint systems
appropriate for their age, weight and size. Oth-
erwise there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child-restraint system that is
appropriate for their age, size and weight.
The rear seats in your vehicle meet the recom-
mendations of the SAE J1819 standard for
safely mounting 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 for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, 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 page95.
Installing child-restraint
systems
Observe the child-restraint system man-
ufacturer's instructions when selecting,
installing and using child-restraint systems.
Otherwise the protective effect may be dimin-
ished.<
Standard child-restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly
or improperly installed child-restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger's seat
Before installing a child-restraint system
on the front passenger's seat, make sure
that the front and side airbags for the front pas-
senger are deactivated, otherwise there is an
increased risk of injury if the airbags deploy.<
Backrest width*
The backrest width of the front passen-
ger's seat must be at its widest possible
setting. Do not change the setting after install-
ing the child seat. Otherwise the child seat's
stability on the front passenger's seat is lim-
ited.<
1.Adjust the backrest width to its widest set-
ting, refer to page46.
2.Install the child seat.

Wheels and tires

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transport.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 3006 means that the
tire was manufactured in week 30 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.< e.g.
