Pinch protection system
If the belt hand-over encounters resistance on
moving in or out, it moves back slightly in the
opposite direction and stops in this position. To
reactivate the belt hand-over: open and close
the door or switch the ignition off and on.
Although there is a pinch protection sys-
tem, always check that the maneuvering
area of the belt hand-over is clear. Otherwise it
cannot be ensured that the system will stop
moving in certain extreme situations.<
Mirrors
Exterior mirrors
The front passenger's mirror is more con-
vex 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;
otherwise, there is an increased risk of an acci-
dent.<

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 narrow 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

driver to see the area immediately adjacent
to the vehicle, e.g. a curb, when backing into
a parking space.
Deactivating
Push the switch to the position for the passen-
ger side mirror, arrow 2.

Transporting children safely

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.<
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.
Children in the 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.<
For more information on automatic deactivation
of the front passenger airbags refer to page98.
Installing child restraint
systems
Observe the child restraint system manu-
facturer'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 seat
After installing a child restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated; otherwise, there is an
increased risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the front passenger seat as far back and up as
possible to obtain the best possible position for
the belt. Do not change the seat position after
this.
Backrest width*
The backrest width of the front passenger
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise, the child seat's stabil-
ity on the front passenger seat is limited.<
1.Adjust the backrest width to its widest
setting, refer to page44.
2.Install the child seat.
Child seat security
The rear safety belts and the front passenger
safety belt can be prevented from being pulled
out in order to fasten child restraint systems.

Wheels and tires
218
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 Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in
the tire coding: DOT … 1010 means that the
tire was manufactured in week 10 of 2010.
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

Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage.<
After washing the vehicle, apply the
brakes briefly to dry them; otherwise,
water can reduce braking efficiency over the
short term and the brake discs can corrode.<

Preference should be given to cloth car washes.
Do not use high-pressure car washes;
otherwise, water may drip into the vehicle
around the windows.<
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following:
>Dimensions of your vehicle, refer to
page247.
>If necessary: fold in the exterior mirrors,
refer to page50.
>Maximum permissible tire width.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is the
danger of damaging chassis parts.<
Preparations before driving into an automatic
car wash:
>Unscrew the rod antenna
*.
>Deactivate the rain sensor
* to prevent
unintentional wiping.
>Remove additional add-on parts,
e.g. spoilers or phone antennas, if they
could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Move the selector lever to position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
