Retractable hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
Please note:
>It is advisable that you 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 area.
>Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
>Do not attach rack systems 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 operating 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 area. If necessary, remove items
from the cargo area 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 retractable 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 the mechanism while the
hardtop is opening or closing. Keep children

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control
Display.
Check coolant level, refer to page204.
Engine oil temperature*
When the engine is at normal operating
temperature, the engine oil temperature is
between approx. 2107/1006 and approx.
3007/1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14.5 US gallons/
55 liters.
You can find information on refueling
on page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<

Wheels and tires
200
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 +457/+76.
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 tires, 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 against 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 this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
Snow chains*
Only certain fine-link snow 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 page78.<

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. 6.2 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
1.Push button 1 in the turn indicator lever up

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 page69. Have the system checked as
soon as possible.
Adding engine oil
Do not add 1 US quart/1 liter of engine oil until
a corresponding message is shown on the
Control Display.
Add oil within the next 125 miles/200 km;
otherwise, the engine damage could
occur.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
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.
Oil types
Do not use oil additives as these may
cause engine damage.<
Specified engine oils
Your service center can advise you on which
engine oils have been approved by the manu-
facturer of your vehicle.
The engine oil quality is critical for the life of the
engine.Approved oils can be identified by the following
specification:
Approved oils belong to the following viscosity
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant consists of half water and half additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW center for
suitable additives.
Only use suitable additives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is
important to follow the instructions on the con-
tainers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Do not open the engine hood before the
engine has cooled down.
2.Turn the expansion tank cap counterclock-
wise slightly to allow any accumulated pres-
sure to escape, then continue turning
to open.
