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 convertible top when the
rollover protection system is in the acti-
vated 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 page72.<

Things to remember when driving
116 >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
retaining straps
*, a cargo area net* or 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, arrows 1,
on the inside wall of the cargo area.
Depending on your vehicle's equipment,
there may be two additional lashing eyes,
arrows2, on the cargo area sidewalls.
Follow the information included with the
cargo straps.
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 approved axle loads, refer
to page229, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic 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 occu-
pants.
Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page53, otherwise, these could be damaged.<
Coupe: roof-mounted
luggage rack*
A special rack system is available as an option
f o r y o u r B M W . C o m p l y w i t h t h e d i r e c t i o n s g i v e n
in the installation instructions.
Mounting points
Fold open the cover.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the applicable data under Weights
on page229.
The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure
that adequate clearance is maintained for rais-
ing the glass roof, and that objects do not
project into the opening path of the trunk lid.
Fasten roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.

Wheels 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 … 1010 means that the
tire was manufactured in week 10 of 2010.
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.
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.
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.< e.g.

Care
212 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.
Carpet/floor mats*
The floor mats can be removed for cleaning.
When heavily soiled, clean carpets with a
microfiber cloth and water or textile cleaner.
Rub back and forth in the direction of travel; oth-
erwise, the carpet may become matted.
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.
Avoid applying excessive pressure when
cleaning the displays; otherwise, damage
may occur. hold cleaning agents. Keep all types of
fluid away from the device. Otherwise, surfaces
or electrical components may be corroded or
damaged.<
CD/DVD drives
Do not use a cleaning CD, as it may dam-
age parts of the drive.<
Vehicle storage
If your vehicle is to be decommissioned for
longer than three months, your BMW center or
a workshop that operates according to BMW
specifications will be glad to advise you.
