Retractable hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
Please note:
> It is advisable that yo u close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked
cargo bay.
> Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
> Do not attach rack sy stems to the luggage
compartment lid, and in particular do not
attach magnetic racks.
> When the retractable hardtop is operated,
the luggage compartment lid swings back
and up. Before operat ing the retractable
hardtop, ensure that there is enough clear-
ance, e.g. in tight parking spaces.
> If you open the hardtop while it is wet, e.g.
after driving in the rain, water may drip into
the cargo bay. If necessary, remove items
from the cargo bay beforehand to avoid
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the luggage compart-
ment lid, otherwise they could fall during move-
ments of the retracta ble hardtop and cause
damage or injury.
Driving when the hardtop is not fully opened or
not fully closed may result in damage or injury.
Do not reach into th e mechanism while the
hardtop is opening or closing. Keep children

Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between

Wheels and tires
196
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for winter roads
or at temperatures below +45 7/+7 6.
Although all-season M+ S tires provide better
winter traction than summer tires, they gener-
ally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents. <
If the car is capable of speeds higher than that
permitted for the winter ti res, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as th is could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels betwee n the axles is not per-
missible.
Snow chains*
Only certain fine-link sn ow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information.
Snow chains must be mounted in pairs and on
the rear wheels only. Observe the manufac-
turer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page 78.<

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking engine oil level
Your car is equipped with an electronic oil-level
monitor.
For the oil level to be measured and displayed
correctly, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
Display in the instrument cluster

or down repeatedly until the appropriate
symbol is shown in the display, accompa-
nied by the word "OIL".
