ControlsTechnology for driving comfort and safety
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling inst ructions under Trans-
porting children safely, refer to page 58.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indi cator lamp for the front
passenger airbags lights up. In such cases, the
passenger should change his or her sitting
position so that the fr ont 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 in tended, on the seat.
The front and side airbags for the front
passenger are not activated. Most child seats are detected by the
system. This partic
ularly applies to
child seats that were required by NHTSA at
the time of manufacture of the vehicle. After
mounting a child seat, ensure that the indi-
cator lamp for the fron t passenger airbag is
lit. It indicates that th e child seat has been
detected and that the front passenger air-
bags are deactivated. <
> The indicator lamp does n o t c o m e o n w h e n ,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat.
The front and side airbags for the front
passenger are activated.
> The indicator lamp does not light up if the
seat is empty.
The front and side airbags for the front
passenger are not activated.
Operational readine ss of airbag system
As of radio readiness, refer to page 61, the
warning lamp lights up br iefly 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 withou t delay; otherwise,
there is the risk that th e system will not function
as intended even if a sufficiently severe acci-
dent occurs. <

Technology for driving comfort and safety
Controls
Convertible: rollover
protection system
The rollover protection
system is activated
automatically in the event of an accident of suf-
ficient severity or an extreme tilt in the car's lon-
gitudinal axis. The protection bars behind the
rear head restraints depl oy within fractions of a
second.
As a supplementary system to the reinforced
windshield frame, the rollover protection
system increases the safety of the 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 sa fety 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.
If the rollover protective system is
extended, do not operate the convertible
top.
Do not make any modifica tions to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
be performed only by your BMW center.
Faulty repair may lead to the failure of the sys-
tem or malfunctions.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page 80.<

Driving tipsThings to remember when driving
1,400 lbs and there will be five 150-lb
passengers in your vehicle, the amount of
available cargo and lugga ge 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 tra iler will be transferred
to your vehicle. Co nsult 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 sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
Coupe Convertible
Storing cargo
>
Position heavy objects as low and as far
forward 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.
Securing cargo
> Secure smaller and lighter items using draw
straps.
> Heavy-duty cargo straps for securing larger
and heavier objects are available at your
BMW center. To attach the cargo straps,
there are two lashing eyes on the inside wall
of the trunk.
Comply with the information enclosed with
the load-securing devices.
Always position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle
weight or either of the a pproved axle loads, refer
to page 259, as excessive loads can pose a
safety hazard, and may al so place you in viola-
tion of traffi c safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the
occupants.

MobilityWheels and tires
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 … 1013 means that the
tire was manufactured in week 10 of 2013.
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 betw een 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 Requir ements 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 conditio ns on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditio ns 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.
These grades represent the tire's ability to stop
on wet pavement, as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.

Care
Mobility
In order to prevent staining, e.g due to clothing,
clean the leather approximately every two
months.
Clean light-colored leather
more frequently as it
shows dust and dirt more noticeably.
Use BMW Premium Leather Care since dirt and
grease will otherwise slow ly affect the protec-
tive layer of the leather.
Suitable care products are available at your
BMW center.
Upholstery care
Regularly vacuum with a vacuum cleaner.
To remove severe spots such as beverage
stains, use a soft sponge or lint-free microfiber
cloth and suitable interior cleaners.
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. <
Care of special parts
Light-alloy wheels
When cleaning on the vehicle, use only neutral
rim cleaner with a pH value of 5 to 9. Do not use
coarse cleansers and do not use steam clean-
ers at temperatures greater than 140 7/60 6.
Follow manufacturer's instructions.
Aggressive, acid-containing, or strongly alka-
line cleaning agents can destroy the protective
coating of nearby components such as the
brake discs.
Chrome look surfaces
Carefully clean vehicle parts such as the radia-
tor grill or door handles with copious quantities
of water and possibly a shampoo additive, par-
ticularly when roads ar e treated with deicing
salt.
Rubber parts
Treat only with water or rubber care products.
Do not use silicon-containing care products on
rubber seals; otherwis e, noise and damage
could occur.
Fine wood parts
Clean fine wood trim an d fine wood parts only
with a damp cloth. Wipe dry with a soft cloth.
Plastic parts
These include:
>Imitation leather surfaces
> Roofliner
> Lamp glasses
> Display pane of instrument cluster
> Parts spray painted matte black
> Painted parts in the passenger
compartment
Use a microfibre cloth for cleaning.
Moisten the cloth slightly with water.
Do not soak the roofliner. Do not use any cleaners that contain alco-
hol or solvents such as lacquer thinner,
cold cleaning agents, fuel, and the like; other-
wise, you may damage the surfaces. <
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Do not clean chemic ally, as this may
destroy the webbing. <
Only clean with a mild soap solution in the
installed state.
Only reel in seat belts when they are dry.
