Status of passenger airbags
The indicator lamp for the front passenger air‐
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica‐
tor lamp shows whether the passenger airbags
are activated or deactivated.
▷The indicator lamp lights up when a child
who is properly seated in a child restraint
system intended for that purpose is de‐
tected on the seat or the seat is empty.
The front and side airbags on the front
passenger side are not activated. Most
child seats are detected by the system, Es‐
pecially the child seats required by NHTSA
at the time that the vehicle was manufac‐
tured. After installing a child seat, make
sure that the indicator lamp for the front
passenger airbags lights up. This indicates
that the child seat has been detected and
the front passenger airbags are not acti‐
vated.▷The indicator lamp does not light up when,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat. The front and front passenger air‐
bags on the front passenger side are acti‐
vated.Operational readiness of airbag
system
When the ignition, refer to page 56, is switched
on, the warning lamp comes on briefly to indi‐
cate that the entire airbag system and the belt
tensioners are operational.
Airbag system malfunction
▷The warning lamp does not light up when
the ignition is switched on.▷Warning lamp remains permanently on.
Have the airbag system checked without
delay if there is a malfunction
In the event of a malfunction in the airbag sys‐
tem, have it checked without delay; otherwise,
there is the risk that the system will not func‐
tion as intended even if a sufficiently severe
accident occurs.◀
Flat Tire Monitor FTM The conceptThe system detects a pressure loss in a tire on
the basis of speed differences between the in‐
dividual wheels during a trip.
In the event of pressure loss, the rolling cir‐
cumference changes and, thus, the rotating
speed of the affected wheel. This change is
detected and is reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐

flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv‐
er's responsibility to maintain correct tire pres‐
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal‐
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the in‐
stallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en‐
sure that the replacement or alternate tires andwheels allow the TPMS to continue to function
properly.
Brake force display
The concept▷During normal brake application, the brake
lamps light up.▷During heavy brake application, the turn
signals light up in addition.
The brake force display is not activated if the
turn signal function is switched on.

Close both windows
An open window causes higher air resistance
and thus increases fuel consumption.
Tires
General information
Tires can have varying effects on fuel con‐
sumption; for example, fuel consumption can
be influenced by the tire size.
Check the tire inflation pressure
regularly
Check and, if necessary, correct the tire infla‐
tion pressure, refer to page 227, at least twice
a month and before starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without delay Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐ cle driving ahead of you.
Driving smoothly and looking ahead reduces
fuel consumption.
Avoid high engine speeds
Use 1st gear to get the vehicle in motion. Be‐
ginning with 2nd gear, accelerate rapidly.
When accelerating, shift up before reaching high engine speeds.
When you reach the desired speed, shift into
the highest applicable gear and drive with the
engine speed as low as possible and at a con‐
stant speed.As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use coasting conditions
When approaching a red light, take your foot
off the accelerator and coast to a halt in the
highest applicable gear.
On a downhill slope, take your foot off the ac‐
celerator and coast in a suitable gear.
The flow of fuel is interrupted while coasting.
Switch off the engine during longer
stops
Switch off the engine during longer stops, e.g.,
at traffic lights, railroad crossings or in traffic
congestion.
Automatic Engine Start/Stop Function
The Automatic Engine Start/Stop Function au‐
tomatically switches the engine off during a
stop.
If the engine is stopped and then started again,
fuel consumption and emissions drop com‐
pared to an engine that runs permanently.
Stopping the engine even for just a few sec‐
onds can result in savings.
Use of this system can cause premature wear
on certain vehicle components.
In addition, fuel consumption depends on
other factors as well, such as driving style, road
conditions, maintenance, and environmental
factors.
Additional information on the Automatic En‐
gine Start/Stop Function, refer to page 57.
Switch off any functions that are not
currently needed
Functions such as the automatic climate con‐
trol require a large amount of energy and con‐
sume additional fuel, especially in city and
stop-and-go traffic.
Therefore, switch off these functions if they
are not actually needed.Seite 133Things to remember when drivingDriving tips133

Tire inflation pressure
Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres‐
sure.
Check the tire inflation pressure regularly
Regularly check the tire inflation pres‐
sure and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Checking the pressure Only check the tire inflation pressure when the
tires are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle
has been parked for at least 2 hours. When the
tires are warm, the tire inflation pressure is
higher.
After correcting the tire inflation pressure, rein‐
itialize the Flat Tire Monitor, refer to page 92.
After correcting the tire inflation pressure, re‐
set the Tire Pressure Monitor, refer to page 95.Pressure specifications
The tables below provide all the correct infla‐
tion pressures for the specified tire sizes at
ambient temperature.
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
service center.
For correct identification of the right tire infla‐
tion pressures, observe the following:▷Tire sizes of your vehicle.▷Maximum allowable driving speed.
Tire inflation pressures for driving up
to 100 mph or 160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column for traveling speeds up to 100 mph/
160 km/h to achieve optimum driving comfort.
These tire inflation pressures can also be
found on the driver's side door pillar when the
driver's door is open.
Do not exceed the maximum permissible
speed
The maximum permissible speed for these tire
pressures is 100 mph/160 km/h Do not exceed
this speed; otherwise, tire damage and acci‐
dents could occur.◀

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
