Reporting safety defects
For US customers
The following only applies to vehicles owned
and operated in the US.
If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration,
NHTSA, in addition to notifying BMW of North
America, LLC, P.O. Box 1227, Westwood, New
Jersey 07675-1227, Telephone 1-800-831-
1117.
If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order
a recall and remedy campaign. However,
NHTSA cannot become involved in individual
problems between you, your center, or BMW of
North America, LLC.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
http://www.safercar.gov; or write to: Adminis-
trator, NHTSA, 400 Seventh Street, SW.,
Washington, DC 20590. You can also obtain
other information about motor vehicle safety
from http://www.safercar.gov
For Canadian customers
Canadian customers who wish to report a
safety-related defect to Transport Canada,
Defect Investigations and Recalls, may call
1-800-333-0510 toll-free from anywhere in
Canada or 1-613-993-9851 from the Ottawa
region and from other countries, or contact
Transport Canada by mail at: Transport Can-
ada, ASFAD, Place de Ville, Tower C,
330 Sparks Street, Ottawa, ON, K1A 0N5.

Opening and closing
30 as very thin objects, and the roof would con-
tinue closing.<
Closing without pinch protection
If there is an external danger, press the switch
forward past the resistance point and hold it
there. The roof closes without pinch protection.
Following interruptions in electrical
power supply
After a power failure, there is a possibility that
the glass roof can only be raised. The system
must be initialized. BMW recommends having
this work done by your BMW center.
Closing manually*
In the event of an electrical malfunction, you can
move the glass roof manually:
1.Unclip the front of the cover of the interior
lamps using the screwdriver from the
onboard vehicle tool kit, refer to page124.
2.On both sides, use the screwdriver to press
on the clip inside the opening.
3.Remove the control unit.4.Unplug the motor. Considerably less effort
will be required for manual operation.
5.Insert the Allen wrench
* supplied with the
onboard vehicle tool kit, refer to page124,
into the opening provided. Move the glass
roof in the desired direction.
6.Reattach the lamp cover and reinstall the
control unit.
Convertible: top
The fully automatic top combines reliable
weather protection with simple and easy-to-
use operation.
The following tips will enhance your driving
pleasure in your Convertible:
>It is advisable that you close the convertible
top when you park the vehicle. Not only
does the closed top protect the vehicle inte-
rior against unanticipated weather damage,
it also offers a certain amount of theft pro-
tection. However, even when the top is
closed, valuables should only be stored in
the locked cargo area.
>Do not attach roof-mounted luggage sys-
tems to the convertible top.

heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material 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 Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page112.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Designation for specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 1/8 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
1/16 in/1.6 mm. At tread depths below 1/8 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth of 1/6 in/4 mm, they become perceptibly less
suitable for winter conditions. In the interest of
safety, new tires should be installed.
Wear indicators in the base of the tread groove
are distributed around the tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. Once the tire tread has
worn down to the wear indicators, the tire has
worn to a depth of 1/16 in/1.6 mm.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazard and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there.
Otherwise, tire damage can pose a lethal hazard
to vehicle occupants and other road users.<
