ControlsOpening and closing
After switching off the ignition
When the remote control  is removed or the igni-
tion is switched off, you can still operate the roof 
for approx. 1 minute as long as no door has 
been opened.
Pinch protection system
If the glass roof encounters an obstruction dur-
ing closing from approximately the middle of 
the opening in the roof, or during closing from 
the tilted position, the closing movement is 
interrupted and the glass roof is opened again 
slightly.
Despite the pinch protection system 
check and clear the roof's travel path prior 
to closing it; otherwise,  the safety system might 
fail to detect certain kinds of obstructions, such 
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 resistan ce 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 tilted. The system 
must be initialized.  BMW recommends having 
this work performed at your BMW center.
Convertible: 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 recommended that you close the con-
vertible top whenever the vehicle is parked. 
The closed convertible top not only pro-
tects the vehicle interior from damage due 
to unforeseen bad we ather, but also pro- vides a certain degree of protection against 
theft. However, even when the top is 
closed, valuables should
 only be stored in 
the locked trunk.
> Do not mount any roof rack systems on the 
convertible top.
> If the top is opened while it is wet, e.g. after 
driving in the rain, water may drip into the 
trunk. If necessary, remove items from the 
trunk beforehand to av oid water stains or 
soiling.
At temperatures below +14 7/–10 6, do 
not move the convertible top as this could 
result in damage.
Do not keep the convertible top in the convert-
ible top box for longer than  one day if it is wet; 
otherwise, the moistu re may cause damage.
Do not place objects on the convertible top, as 
otherwise they may fall off when you operate 
the convertible top and cause damage or injury.
Never move the converti ble top when the roll-
over protection system is in the activated 
position.
Always completely finish the operation of the 
convertible top. Driving  with the convertible top 
incompletely opened or  closed can result in 
damage or injury.
Do not reach into the mechanism during the 
opening or closing procedure. Keep children 
away from the opening/closing path of the 
convertible top.
For safety reasons, only operate the convertible 
top while the vehicle is standing. <
While opening and closing, the convert-
ible top pivots upward. When operating 
the convertible top in a garage, under a bridge, 
etc., ensure that there are at least 6.5 ft/2 m of 
headroom; otherwise, the vehicle may be 
damaged. <

ControlsControls overview
Tachometer
Never force the engine speed up into the red 
warning field, see arrow. In this range, the fuel 
supply is interrupted to protect the engine.
Engine oil temperature
When the engine is at normal operating temper-
ature, the engine oil temperature is between 
approx. 2107/100 6 and approx. 300 7/
150 6.
If the engine oil temp erature is too high, a 
message appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14 US gal/53 liters.
You can find information on refueling on 
page 221.
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.
Fuel display 135i: in speedometer.
Reserve
Once the fuel level ha s fallen to the reserve 
zone, a message briefly  appears on the Control 
Display and the remaining  cruising range is dis-
played on the computer. Under a cruising range 
of approx. 30 miles/50 km, the message 
remains in the Control Display.
With a dynamic driving style, e.g. rapid corner-
ing, engine functions are not always assured.
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
Mobility
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 driving on 
winter roads or at temperatures below +45
7/
+7 6. Although all-season M+S tires provide 
better winter traction th an summer tires, they 
generally 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 
accidents. <
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
Store wheels and tires in a cool, dry place with 
as little exposure to light as possible. Always 
protect tires against all co ntact with oil, grease 
and fuels.
Do not exceed the maximum tire inflation 
pressure indicated on th e 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 between the axles is not 
permissible.
Run-flat tires
The symbol identifying run- flat tires is a circle 
with the letters RSC on the sidewall. 
Run-flat tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls en sures that the tire can 
continue to be used su bject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat 
tire, refer to Indication  of a flat tire on page92.
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 manufacturer's instructions when 
mounting snow chains. Do not exceed a speed 
of 30 mph/50 km/h with chains.
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 DT C temporarily, refer to 
page 89.<

Do not work on the car unless you pos-
sess the necessary technical knowledge. 
If you are not familiar with the regulations to be
