activated, refer to Status of front passenger air-
bags below.<
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, refer to page52.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indicator lamp for the front
passenger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the front passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise, a correct analysis of the seat cushion is
not ensured.<
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger front and side airbags in accordance
with whether and how the front passenger seat
is occupied. The indicator lamp shows whether
the front passenger airbags are activated or
deactivated.
>The indicator lamp lights up when a child in
a specially designated child restraint sys-
tem is detected, as intended, on the seat.
The front and side airbags for the front pas-
senger are not activated.Most child seats are detected by the
system, especially child seats
required by the NHTSA at the time of vehi-
cle production. After mounting a child seat,
ensure that the indicator lamp for the front
passenger airbag is lit. It indicates that the
child seat has been detected and that the
front passenger airbags are deactivated.<
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat.
The front and side airbags for the front pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty.
The front and side airbags for the front pas-
senger are not activated.
Operational readiness of airbag system
As of radio readiness, refer to page55, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
>Warning lamp does not light up at radio
readiness or beyond.
>Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay; otherwise,
there is the risk that the system will not function
as intended even if a sufficiently severe acci-
dent occurs.<

Technology for driving comfort and safety

Convertible: rollover
protection system
The rollover protection system is activated
automatically in the event of an accident, a crit-
ical driving situation, an extreme tilt in the car's
longitudinal axis or upon loss of ground contact.
The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants.
Always keep the area of movement of the
rollover protection system clear.
In minor accidents, you are protected by the
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and
multi-phase airbag retention system.<
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1.Push the locking lever to one side and hold
it there.
2.Push the protection bar halfway down from
above.
3.Release the locking lever.4.Push the protection bar down until it snaps
into place.
5.Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked
after an unexpected activation.
Never move the retractable hardtop when
the rollover protection system is in the
activated position.
Do not make any modifications to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
only be performed by a BMW center.
Incorrectly performed work on the system may
lead to system failure or incorrect operation.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page73.<

Practical interior accessories
114 5.Insert the latch plate of the retaining strap
into the belt buckle under the transport bag.
6.Load the transport bag. The zipper eases
access to the stored items.
Only place clean skis in the transport bag. Wrap
sharp edges to prevent damage.
You can use the snaps to shorten the transport
bag if you do not need its full length.
Securing cargo
After loading, secure the transport bag and its
contents. Tighten the retaining strap on the
tensioning buckle for this purpose.
Secure the transport bag in the manner
described; otherwise, it could endanger
the car's occupants, e.g. in case of heavy brak-
ing or sudden swerving.<
To store the transport bag, perform the steps
described for loading in reverse order.
Removing the front cover
You can remove the front cover to use the full
height of the through-loading opening. With the
cover folded down, pull the handle, see arrow,
and remove the cover toward the front. To
replace, insert the cover at an angle from above
and let it snap it into place.

develops inside the tires. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY amount equals
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs:
1,400 lbs. minus 750 lbs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.

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 … 3209 means that the
tire was manufactured in week 32 of 2009.
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 e.g.

Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 1407/606; otherwise, dam-
age may occur.<
Outside sensors/cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g. those for Park
Distance Control, clean and free of ice to ensure
that they remain fully functional.<
Interior care
Upholstery fabrics/cloth trims/
Alcantara fabrics
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To remove severe spots such as stains from
beverages, use a soft sponge or lint-free
microfiber cloth and suitable interior cleaners.
Follow the instructions on the packaging.
Clean the upholstery down to the seams
using a sweeping motion. Avoid strong
rubbing.<
Opened Velcro fasteners on pants or
other articles of clothing can damage the
seat covers. Ensure that Velcro fasteners are
closed.<
Leather/leather trim
The leather used by BMW is a high quality
natural product. Slight irregularities in the
leather are a typical characteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Therefore, fre-
quently clean the leather of dust using a cloth or
vacuum cleaner.Clean light-colored leather more frequently as
dust and dirt are more noticeable.
Treat the leather at least once every two
months using a leather lotion as dirt and grease
will gradually attack the leather's protective
layer.
Carpets/cargo area
You can vacuum the carpets and floor mats or
clean them with interior cleaner if heavily soiled.
The floor mats can be removed for cleaning.
When replacing the mats, ensure that the seat
rails do not extend over the floor mats, as this
may damage the mats.
Lint on the floor mats occurs for technical rea-
sons and can be removed by vacuuming
repeatedly.
Interior plastic parts
>Imitation leather surfaces
>Lamp glasses
>Display pane of instrument cluster
>Matte parts
Clean with water and solvent-free plastic
cleaner if necessary.
Fine wood parts
Clean fine wood trim and fine wood parts with a
damp cloth. Wipe dry with a soft cloth.
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean chemically, as this may
destroy the webbing.<
Interior sensors/cameras
To clean interior sensors and cameras, e.g. of
the high-beam assistant, use a lint-free cloth
moistened with glass cleaner.
Displays
To clean displays, e.g. of the radio or instrument
cluster, use a cleaning cloth for displays or a
soft, non-abrasive, lint-free cloth.
