Safety belts
General information
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
Seats with safety belt The vehicle has two seats, each of which is
equipped with a safety belt.
The shoulder strap's anchorage point will be
correct for adult seat occupants of every build
if the seat is correctly adjusted.
One person per safety belt
Never allow more than one person to
wear a single safety belt. Never allow infants or
small children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies
low around the hips in the lap area and does
not press on the abdomen. Otherwise, the belt
can slip over the hips in the lap area in a frontal
impact and injure the abdomen.
The safety belt must not lie across the neck,
rub on sharp edges, be routed over solid or
breakable objects, or be pinched.◀
Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀Seite 50ControlsAdjusting50

The safety belt reminder is active at speeds
above approx. 5 mph/8 km/h. It can also be ac‐
tivated if objects are placed on the front pas‐
senger seat.
Damage to safety belts In the case of strain caused by accidents or
damage:
Have the safety belts, including the safety belt
tensioners, replaced and have the belt anchors
checked.
Checking and replacing safety belts
Have the work performed only by your
service center; otherwise, it cannot be ensured
that this safety feature will function properly.◀

W = up to 167 mph/270 km/h

Tire Identification Number Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
DOT xxxx xxx 0313
xxxx: manufacturer code for the tire brand
xxx: tire size and tire design
0313: tire age
Tire age The tire manufacturing date is contained in the
tire identification mark: DOT ... 0313 means
that the tire was manufactured in the week 3 of
2,013.
BMW recommends that you replace all tires af‐
ter 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:
Treadwear 200 Traction AA
Temperature A
DOT Quality Grades
TreadwearTraction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.◀
Treadwear The treadwear 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
(11/2) 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, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics 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 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,
hydroplaning, or peak traction characteristics.
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 ma‐
terial 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 passengerSeite 232MobilityWheels and tires232

Car washes Notes Steam jets or high-pressure washers
When using steam jets or high-pressure
washers, hold them a sufficient distance away
and use a maximum temperature of
140 ℉/60 ℃.
Holding them too close or using excessively
high pressures or temperatures can cause
damage or preliminary damage that may then
lead to long-term damage.
Follow the operating instructions for the high-
pressure washer.◀
Cleaning sensors/cameras with high-
pressure washers
When using high-pressure washers, do not
spray the seals of the retractable hardtop and
the exterior sensors and cameras, for Park Dis‐
tance Control, for instance, for extended peri‐
ods of time and only from a distance of at least
12 in/30 cm.◀
Regularly remove foreign bodies, such as
leaves, from the area below the windshield
when the hood is open.Wash your vehicle frequently, particularly in
winter.
Intense soiling and road salt can damage the
vehicle.
Washing in automatic car washes Give preference to cloth car washes or those
that use soft brushes in order to avoid paint damage.
Notes Note the following:▷Make sure that the wheels and tires are not
damaged by the transport mechanisms.▷Fold in the exterior mirrors; otherwise, they
may be damaged, depending on the width
of the vehicle.▷Deactivate the rain sensor, refer to
page 64, to avoid unintentional wiper acti‐
vation.▷Unscrew the road antenna.
Guide rails in car washes
Avoid car washes with guide rails higher
than 4 in/10 cm; otherwise, the vehicle body
could be damaged.◀
Before driving into a car wash The vehicle is able to roll if the following steps
are taken.
