Washer fluids for washer
systems
Headlamp* and windshield washer
system
Capacity of windshield washer system:
approx. 3.2 US quarts / 3 liters.
Capacity when equipped with headlamp
washer system: approx. 5.3 US quarts /
5 liters.
Fill with water and – if required – with an
antifreeze agent according to the manufac-
turer's recommendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. For this reason,
keep it away from sources of flame and
store it only in its original container. Store it
so that it is inaccessible to children. Com-
ply with the instructions on the contain-
ers.<
Engine oil
Engine oil pressure
The red engine oil warning lamp
lights up:
Stop the vehicle immediately and
switch off the engine. Check the engine oil
level and top off as required. If the oil level
is correct, please contact the nearest BMW
center.
Do not continue driving, as the engine
could sustain serious damage from
inadequate lubrication.<
Engine oil level
The yellow engine oil indicator lamp
lights up while driving:
The oil level is at the absolute mini-
mum; refill as soon as possible. Do not
drive more than approx. 30 miles / 50 km
until you do.
The yellow engine oil indicator lamp
lights up after the engine is
switched off: add engine oil at the
earliest opportunity, when you stop to
refuel.
Engine oil sensor
The yellow engine oil indicator lamp
lights up within 20 seconds after
the engine is started:
The oil level sensor is defective. Please
have it checked by a BMW center.
Checking the oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil level should be between the two
marks on the dipstick
6.Return the dipstick to the guide tube,
inserting it as far as it will go.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.

Replacement procedures
Onboard tool kit
The onboard tool kit is stored in a tool
pouch. It is located in the luggage compart-
ment beneath the floor panel.
Windshield wiper blades

it toward the windshield
4.Pull the wiper blade past the wiper arm

Lamps and bulbs
The lamps and bulbs make essential contri-
butions to the safety of your vehicle. There-
fore, comply fully with the following instruc-
tions during bulb replacement. If you are
not familiar with the procedures, BMW rec-
ommends that you have your BMW center
carry out the work.
Do not touch the glass portion of a
new bulb with your bare hands since
even small amounts of impurities burn into
the surface and reduce the service life of
the bulb. Use a clean cloth, paper napkin or
a similar material, or hold the bulb by its
metallic base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical sys-
tem, switch off the electrical acces-
sory you are working on or disconnect the
cable from the negative terminal of the bat-
tery. Failure to observe this precaution
could result in short circuits.
To prevent injuries and damage, always
comply with any instructions provided by
the bulb manufacturer.<
Accessing the headlamps
To gain access to the headlamp covers,
turn the front wheels in the required direc-
tion.
