Safety beltsGeneral 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 48ControlsAdjusting48

Buckling the belt
Make sure you hear the latch plate engage in
the belt buckle.
Unbuckling the belt
1.Hold the belt firmly.2.Press the red button in the belt buckle.3.Guide the belt back into its reel.
Safety belt reminder for driver and
passenger
The indicator lamp lights up and a
signal sounds. In addition, a message
appears on the Control Display.
Check whether the safety belt has
been fastened correctly.
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.◀

support are not stored.
Storing
1.Switch on the radio ready state or the igni‐
tion, refer to page 55.2.Adjust the seat and exterior mirrors to the
desired positions.3. Press the button. The LED in the
button lights up.4.Press the desired memory button 1 or 2:
the LED goes out.
If the M button is pressed accidentally:
Press the button again. The LED goes
out.

ting, refer to page 47.2.Install the child seat.
Backrest width for the child seat

pull it taut against the child restraint fixing
system.
The safety belt is locked.
To unlock the safety belt
1.Open the belt buckle.2.Remove the child restraint fixing system.3.Allow the belt webbing to be pulled in com‐

Tire Identification NumberTires 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
2013.
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
Treadwear
Traction 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 oftheir 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 passenger
car 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.
Temperature grade for this tire
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀Seite 231Wheels and tiresMobility231

CareVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
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 62, 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.
Manual transmission
1.Shift to neutral.2.Release the parking brake, refer to
page 59.3.Switch the engine off.4.Leave the remote control in the ignition
lock.Seite 255CareMobility255
