Operational readiness of airbag system
From radio readiness, refer to page56, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up from radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction, otherwise
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<
Convertible: rollover
protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal axis, or loss of ground contact. The
rollover bars located behind the rear head
restraints are deployed within fractions of a sec-
ond.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path 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.<
Lowering
If the rollover protection system experienced no
impact after automatic activation, then it can be
lowered again. No tools are necessary for this
purpose.
1.Press the release backward and hold in that
position.
2.Press the rollover protection unit halfway
down from above.
3.Let go of the release.
4.Press the rollover protection unit down until
it snaps into place.
5.Use the same procedure for the second roll-
over protection unit.
Have the rollover protection system checked
after unexpected triggering.
Never move the convertible top when the
rollover protection system is raised.
No changes of any nature may be made to the
individual components of the rollover protec-
tion system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.

can also be adjusted with the knurled thumb-
wheel of the instrument lighting.
Technology for comfort, convenience and safety
96 Due to the system's need to adjust periodically,
a still image is displayed at certain intervals for
fractions of a second. This is normal and not an
indication of a problem.
To prevent driving without headlamps, at a
speed of more than approx. 3 mph/5 km/h and
when dark, the thermal image on the Control
Display is only shown when the low beams are
on.

Cleaning camera
The function of the camera may be affected by
heavy rain and fog, dirt, snow or ice on the lens.
When this occurs, the displayed image on the
Control Display may become gray.
To minimize icing, the camera lens is automati-
cally heated. However, it may be necessary to
clean the camera lens manually under severe
weather conditions. When doing so, cautiously
remove any debris, ice or snow. To avoid dam-
age to the lens, do not use sharp or abrasive
instruments to clean ice, snow, or dirt off the
lens.
When the windshield is cleaned with the head-
lamps on, the camera lens area is automatically
sprayed as well. Refer to page62.
Lane Departure Warning*
The concept
This system warns you from a speed of approx.
40 mph/70 km/h when the vehicle is leaving the
lane you are currently in on roads with lane
demarcation lines. You feel this due to a slight
vibration of the steering wheel.
The system does not warn you if you signal
before leaving the lane.
It is best to use the system on well-developed
roads and freeways.

from a speed of approx. 40 mph/70 km/h
and warns accordingly.
If you activate the system below a speed of
approx. 40 mph/70 km/h, a message will appear
stating that the system is not active until this
speed is reached.
A warning will be canceled:
>after approx. 3 seconds
>if you return to your lane
>if you brake heavily
>if you signal
System limits
The Lane Departure Warning cannot
serve as a substitute for your personal
judgment in determining the course of the road.
If the system issues a warning, do not move the
steering wheel with unnecessary severity, as
otherwise you could lose control of the vehi-
cle.<
The function of the system may be limited in the
following example situations:
>in heavy fog, rain or snowfall
>with worn-away, poorly visible demarcation
lines, or lines that run together or apart or
are unclear, e.g. in road construction areas
>when demarcation lines are covered by
snow, ice, dirt or a great deal of water
>in tight curves or on narrow roads>when demarcation lines are not white
>when demarcation lines are covered by
objects
>when driving up close behind a vehicle driv-
ing ahead
>with bright counter light
>when the windshield is fogged up, dirty or
covered with stickers, vignettes etc. in the
area of the inside rearview mirror

Weather Band*
Weather Radio is a service of the National Oce-
anic and Atmospheric Administration (NOAA)
of the US Department of Trade. Weather news
flashes are repeated every 4 to 6 minutes and
are routinely updated at intervals of 1 to
3 hours, and more often when necessary. Most
stations operate 24 hours a day. In case of a
storm, the National Weather Service interrupts
the routine weather news and transmits special
warning messages instead. If you have a ques-
tion about NOAA Weather Radio, please con-
tact the nearest office of the National Weather
Service. Details are also provided on the Inter-
net at www.nws.noaa.gov.

204 >"Measuring engine oil level...":
This can take about 3 minutes if the car is at
a standstill on a level surface and the engine
is running, and about 5 minutes while the
car is moving.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
>"Engine oil level below minimum. Add 1
quart!":
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer also
to Adding engine oil below. If the oil level
displayed is below minimum, add engine oil
immediately. Failure to do so may lead to
engine damage.
>"Engine oil level too high! Have this
checked.":
Too much oil will harm the engine.
Have the vehicle checked without
delay.<
>"Measurement inactive. Have this
checked.":
Do not add engine oil. You can continue
your journey. Note the newly calculated dis-
tance remaining to the next oil service, refer
to Service requirements on page75. Have
the system checked as soon as possible.
Adding engine oil
Do not add 1 US quart/liter of oil until a corre-
sponding message is shown on the Control Dis-
play.
Add oil within the next 125 miles/200 km,
otherwise the engine could be dam-
aged.
For this reason, thoroughly wash exposed areas
of skin with soap and water after such work.
Keep oil, grease etc. out of reach of children and
observe the warnings on the containers to pre-
vent health risks.<
Oil change
Have oil changed only at your BMW center or
at a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes. Only
use oils of the specification API SM or higher.
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at 1-
800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Do not use oil additives; under some cir-
cumstances, they can damage your
engine.<
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
The choice of the right SAE grade is based on
the climatic conditions in the region in which
you normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE grades.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
instrument panel.
Exhaust-gas values
The warning lamp lights up:
The vehicle emissions are raised. The
trip can be continued. Have the vehicle
checked as soon as possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will go out
within a few days.<
Data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with
a device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, certain vehicle data can be transmitted or recorded to enable corre-
sponding services.

Care
Car-care products
Regular cleaning and care make a significant
contribution to retaining your BMW's value.
For the cleaning and care of your vehicle, BMW
recommends using only products that BMW
has approved for this purpose.
Your BMW center will be glad to advise you
about products and services for the cleaning
and care of your BMW.
Original BMW Care Products are materi-
als tested, laboratory tested, and tested in
actual use. They offer optimum care and pro-
tection for your vehicle.<
Do not use cleaners that contain alcohol
or solvents; they can damage your vehi-
cle.<
Cleaning agents can contain substances
that are dangerous or pose health risks.
You should therefore heed the warnings and
hazard indications on the packaging. Open the
doors or windows on your vehicle whenever
cleaning the interior. Make sure there is suffi-
cient ventilation in enclosed spaces. Use only
products that are formulated for vehicle clean-
ing.<
Exterior care
Washing your vehicle
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Otherwise, signifi-
cant soiling and road salt can cause damage to
the vehicle.<
After washing the vehicle, apply the
brakes briefly to dry them. Failure to do so
may lead to a reduction in braking efficiency and
also to corrosion of the brake rotors.<
Car washes
Give preference to cloth car washes.Do not use high-pressure car washes
because they can cause drops of water to
penetrate in the vicinity of the windshield.<
Before driving into the car wash, make sure that
it is suitable for your BMW. Pay attention to the
following points:
>Dimensions of your vehicle, refer to
page225.
>If necessary, fold in the outside rearview
mirrors, refer to page51.
>Maximum permissible tire width.
>The convertible top must not be treated
with wax. Make sure that a program without
wax or a special convertible program is
available.
Avoid car washes with guide rail heights
over 4 in/10 cm; otherwise, there is a dan-
ger of damaging chassis parts.<
Preparations for driving into the car wash:
>Deactivate rain sensor to prevent unwanted
wiper activation.
>Remove additional add-on parts, e.g. spoil-
ers or phone antennas, if they could be
damaged.
Automatic transmission
Before driving into the car wash, make sure the
vehicle is able to roll by making sure to:
1.Insert the remote control into the ignition
lock, even with Comfort Access.
2.Shift into transmission position N.
3.Release the parking brake.
4.Switch off the engine.
5.Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 140 °F/606.
