Protect valve stems with valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page95, or reset the Tire Pressure Monitor,
refer to page97.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page248.
Disposal
Have old batteries disposed of by your
BMW center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
restrain the battery to prevent it from tipping
over during transport.<
Power failure
After a temporary power supply interruption,
some settings are lost. Take the following
steps:
>Seat, mirror and steering wheel memory
Store the positions again, refer to page48.
>Time and date
Reset, refer to text starting on page86.
>Radio
Store stations again, refer to page174.
>Navigation system
Wait until the system starts, refer to
page142.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<

Emergency request
Conditions for an emergency request:
>Full preparation package mobile phone.
With this equipment, an emergency request
is still possible when no mobile phone is
paired in the vehicle.
>BMW Assist is activated.
Activating BMW Assist, refer to page214.
>Radio readiness is activated.
>The BMW Assist system is logged on to a
mobile phone network.
>The emergency request system is opera-
ble.
Once your BMW Assist subscription expires,
the BMW Assist system can be deactivated by
a BMW center without you having to visit a
workshop. Once the BMW Assist system has
been deactivated, emergency requests are not
possible. The BMW Assist system can be reac-
tivated by a BMW center after signing a new
contract.
Initiating an emergency request
1.Briefly press protective cover to open.
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
2.Press the SOS button for at least
2seconds.The LED in the button lights up. As soon as the
voice connection to the BMW Assist Response
Center has been established, the LED flashes.
Even if you are unable to answer, the BMW
Assist Response Center can take further steps
to help you under certain conditions.
If conditions allow, remain in the vehicle until
the connection has been established. You will
then be able to provide a detailed description of
the situation.
If the current position of your vehicle can be
determined, it will be transmitted to the BMW
Assist Response Center.
If the LED is flashing but the BMW Assist
Response Center cannot be heard over the
hands-free system, it is possible that the
hands-free system is malfunctioning. You may
still be heard by the BMW Assist Response
Center, however.
Under certain conditions, an emergency
request is automatically initiated immediately
after a severe accident. The automatic collision
notification is not affected by the button being
pressed.
For technical reasons, the emergency request
cannot be guaranteed under unfavorable condi-
tions.
You can also use other services of
BMW Assist with this button, refer to
page209.<

approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks,
follow this sequence when connecting
jumper cables.<
In your BMW, the so-called jump-starting termi-
nal in the engine compartment serves as a pos-
itive terminal for the battery, also refer to engine
compartment overview on page231. The cover
cap is marked with a +.

positive terminal of the battery or to a start-
ing-aid terminal of the vehicle to be started.
4.Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the assisting
vehicle.Your BMW has a special nut as body ground
or negative terminal.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.Starting engine
1.Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
Always keep the screw-in tow fitting with the
vehicle. It can be screwed in at the front or rear
of the BMW.

Giving and receiving assistance
250 Sedan:
It is located in the toolkit in the luggage com-
partment lid, refer to page237.
Sports Wagon:
It is located in the toolkit behind the left side
panel in the cargo bay, refer to page237.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Press the arrow symbol on the cover in the
bumper.

Rear
Being towed
Make sure that the ignition is switched on,
refer to page61, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right. When
the engine is stopped, there is no power assist. This then requires increased effort for braking
and steering. Active steering is deactivated and
larger steering wheel movements are
required.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Automatic and sport automatic
transmission
Before towing, manually release the
transmission lock, even if there is no mal-
function in the transmission. Otherwise there is
a risk that the transmission lock will automati-
cally be engaged during towing.<
Manually unlocking and locking transmission
lock, refer to page65.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km, otherwise the automatic
transmission may be damaged.<
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.

>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
With tow truck for 528xi, 535xi
Do not tow a BMW with xDrive with just
the front or rear axle raised, otherwise the
wheels could lock up and the transfer case
could be damaged.<
Have the vehicle transported on a flatbed sur-
face only.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page248. With a catalytic con-
verter, tow-starting should only be carried out
with the engine cold, and with automatic trans-
missions, the engine cannot be started by tow-
starting.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Switch on the ignition, refer to page61.
3.Shift into 3rd gear.
4.Tow-start with the clutch completely
depressed and slowly release the clutch.
