Engine oil
Checking oil level
1.Park the vehicle on a level surface with
the engine at operating temperature
2.After approx. 5 minutes, pull the
dipstick 3 out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material3.Carefully push the dipstick all the way
into the guide tube and pull it out again
4.The oil should extend to between the
two marks on the dipstick.
The engine oil consumption is dependent
on driving style and driving conditions.
The oil quantity between the centers of the
two marks on the dipstick, refer to arrows,
is approx. 1.6 US quarts/1.5 liters. Do not
fill beyond the upper mark on the dipstick.
Excess oil can damage the engine.

Replacing components
Onboard tool kit
The onboard tool kit 1, the screw-in tow
fitting 2 and spare fuses and a pair of plas-
tic tweezers 3 are stored in the luggage
compartment. Fold up the cover located
under the floor mat.
Windshield wiper blades
To replace, fold the wiper arm up and hold.
Press the locking lugs together while push-
ing the wiper blade out of the detent toward
the front.
Lamps and bulbs
Lamps and bulbs make an essential contri-
bution to vehicle safety. Therefore, comply
fully with the following instructions during
bulb replacement. If you are not familiar
with the specified procedures, have the
replacements carried out at your BMW
center.Never touch the glass on new bulbs
with your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life.
Use a clean cloth, napkin etc., or hold the
bulb by its metal socket.<
You can obtain a selection of replacement
bulbs at your BMW center.
When working on the lighting system
you should always switch off the
lights affected to prevent short circuits.
To avoid possible injury or equipment dam-
age when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<
When performing maintenance on the
headlamps, comply with the instructions in
the separate Caring for your vehicle bro-
chure.
In the case of bulbs where the
replacement is not described, please
consult your BMW center.<
Xenon lamps
The service life of these lamps is very long
and the probability of a failure is very low,
provided that they are not switched on and
off an unusual number of times. In the
unlikely event that one of these lamps
should fail, you can continue driving under
poor visibility conditions by switching on
your fog lamps and proceeding carefully,
where allowed by law.
To avoid the risk of potentially fatal
injuries: owing to the extremely high
voltages at which these units operate, ser-
vice work on the xenon lighting system
should only be carried out by a BMW cen-
ter.<
