The warning lamp lights up in yellow
after the engine is switched off. A signal
also sounds.
Check the engine oil level using dipstick7 at the
earliest opportunity, e.g. when you stop to
refuel, and refill engine oil.
The warning lamp lights up in yellow
within 30 seconds after the engine is
started:
The oil level sensor is defective. Have the sys-
tem checked as soon as possible.
Checking the oil level
1.Position the vehicle on a level surface.
2.Switch off the engine when it is at operating
temperature.
3.After approx. 1 minute, pull dipstick 7 out
and wipe it off with a clean, lint-free cloth,
paper towel or something similar.
4.Carefully push the dipstick fully into its tube,
then pull it out again.
The oil level must be between the two
marks on the dipstick.
The oil volume between the two marks on the
dipstick corresponds to approx. 1.4 US quarts/
1.3 liters.
Adding engine oil
Do not add oil until the oil level has dropped
almost to the lower mark on the dipstick, refer to
Checking the oil level.
Do not add oil beyond the upper mark on
the dipstick, otherwise excessive oil can
lead to engine damage.<
Before you check the engine oil level after add-
ing oil, restart the engine and let it run to obtain
a correct reading. Then proceed as described
under Checking the oil level.
BMW engines are designed to operate
without oil additives; the use of additives
could even lead to damage in some cases. The
same applies to the transmission and differen-
tial as well as to the power steering.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For this
reason, thoroughly wash any areas of skin that
have come into contact with oil using soap and
water.
Keep oils, greases, etc. out of the reach of chil-
dren and comply with the warnings on the con-
tainers. Otherwise, health hazards may result.<
Comply with the applicable environmen-
tal regulations concerning the disposal of
used oil.<
Recommendation: have the oil changed at your
BMW center.
Approved engine oils
The quality of the engine oil is extremely impor-
tant for the function and life of an engine. BMW
only approves specific oils after confirming their
suitability for use in its vehicles with extensive
testing.

9Connecting hose for connecting compres-
sor and sealant bottle or compressor and
wheel
Connector, cable and connecting hose are
attached to the bottom of the compressor.
Using the M Mobility System
To repair a flat tire with the M Mobility System,
proceed as follows:
>Fill sealant into wheel
>Distribute sealant
>Restore tire inflation pressure
Filling sealant into wheel
Strictly adhere to the specified order, oth-
erwise highly pressurized sealant could
escape.<
1.Shake sealant bottle.
2.Screw hose9 onto connection of sealant
bottle.
3.Unscrew and remove dust cap from valve of
defective wheel and screw filler hose2 of
sealant bottle onto valve.
4.Insert sealant bottle on compressor hous-
ing so that the bottle is in an upright posi-
tion.
5.Make sure that the device is switched off,
position 0.
6.Insert connector 3 into cigarette lighter
socket inside the vehicle.
7.With the ignition switched on:
Switch on the device and allow it to run for
approx. 3 minutes to fill the wheel with seal-
ant. It is not important what inflation pres-
sure the tire has after this.8.Switch off device.
9.Remove connecting hoses from connection
of sealant bottle and tire valve.
Stow the M Mobility System in the vehicle
again.
Distributing sealant
Immediately drive approx. 2 miles/3 km so that
the sealant is evenly distributed in the tire.
Do not exceed a speed of 35 mph or
60 km/h. Do not drive slower than 12 mph
or 20 km/h if possible.<
Restoring tire inflation pressure
1.After approx. 2 miles/3 km, pull over at a
suitable location.
2.Screw compressor hose9 directly onto tire
valve.
3.Insert connector 3 into cigarette lighter
socket inside the vehicle.
4.Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>To increase inflation pressure: switch on
the compressor, position I. To check the
current pressure setting, briefly switch
off the device.
Do not allow the compressor to run
for more than 10 minutes, otherwise
the device will overheat and may be dam-
aged.<
>To reduce inflation pressure: press but-
ton 8.
If the inflation pressure is not maintained,
drive the vehicle again, refer to Distribut-
ing sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire punctures larger than approx. 1/6 in/
4 mm. Please contact the nearest BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel if the tire cannot be made ready for
driving with the M Mobility System.<
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise do not con-
tinue driving.<
