These lamps use LED technology for operation.
In the event of a malfunction, please contact
your BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.
Changing wheels
Your BMW is equipped with run-flat tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire
on page81.
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
Run-flat tires, page199.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount run-flat tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page199.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<

>BMW Assist is activated. Activating
BMW Assist, refer to page186.
>Radio readiness is on.
>The BMW Assist system is logged on to a
wireless network.
>The Emergency Request system is
operable.
>Equipment version with full preparation
package mobile phone. This equipment
makes it possible to send an Emergency
Request even if no mobile phone is paired
with the vehicle.
Once your service contract for BMW Assist
expires, the BMW Assist system can be deacti-
vated 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 reactivated by a BMW center after a new
contract has been signed.
Sending an Emergency Request
1.Briefly press the cover flap to open.
2.Press the SOS button until 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.Once the BMW Assist Response Center has
received your Emergency Request, the
BMW Assist Response Center contacts you
and takes further steps to help you. Even if you
are unable to respond, the BMW Assist
Response Center will be able to initiate further
steps to assist you under certain conditions.
If the circumstances allow this, remain in the
vehicle until the connection has been estab-
lished. You will then be able to provide a
detailed description of the situation.
In a BMW Assist Emergency Request, data for
determining the necessary rescue measures
are transmitted to the BMW Assist Response
Center, e.g., the current position of your vehicle,
if it can be determined.
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 sent automatically immediately after
a severe accident. This Automatic Collision
Notification is not affected by the button being
pressed.
For technical reasons, the Emergency
Request service cannot be guaranteed
for the most unfavorable conditions.<

BMW Roadside Assistance is there to assist
you around the clock in the event of a break-
down, including on weekends and public
holidays.

Jump-starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You can also use the same method to help start
another vehicle. Only use jumper cables with
fully-insulated clamp handles.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Carefully adhere to the follow-
ing sequence, both to prevent damage to one or
both vehicles, and to guard against possible
personal injuries.<
Preparation
1.Check whether the battery of the other
vehicle has a voltage of 12 volts and
approximately the same capacitance in Ah.
This information can be found on the
battery.
2.Switch off the engine of the assisting
vehicle.
3.Switch off any consumers 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
Connect the jumper cables in the correct
order, so that no sparks which could
cause injury occur.<
Your BMW has a jump-starting connection in
the engine compartment which acts as the bat-
tery's positive terminal, refer also to the Engine
compartment overview on page202. The cap is
marked with +.
1.Pull the cap of the BMW jump-starting con-
nection up to remove.

minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
2.Start the engine on the other vehicle in the
usual way.
If the first start 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 above connecting sequence.

than the driver in a vehicle that is being
towed.<
Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be screwed in at the front or
rear of the BMW.
It is stored in the onboard vehicle tool kit under-
neath the floor panel in the cargo area, refer
to page212.
Use only the towing eyelet supplied with
the vehicle and screw it in firmly until it
stops. Use the tow fitting for towing on paved
roads only. Avoid lateral loading of the tow fit-
ting, e.g., do not lift the vehicle by the tow fitting.
Otherwise, the tow fitting and the vehicle could
be damaged.<

be impossible to maintain control.<
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 angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
