In vehicles equipped with BMW Assist or
TeleService, you can establish contact with
BMW Roadside Assistance for breakdown
assistance directly via iDrive, refer to page185.
First aid pouch*
Some of the articles contained in the first aid
pouch have a limited service life. Therefore,
check the expiration dates of the contents reg-
ularly and replace any items in good time, if nec-
essary.
The first aid pouch is located on the lateral stor-
age shelf behind the seats.
Warning triangle*
The warning triangle is located in a holder in the
luggage compartment lid. Press the tabs to take
it out.
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.

Giving and receiving assistance
220 2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-aid terminal of the vehi-
cle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a starting-aid terminal of
the vehicle to be started.
4.Attach one terminal clamp of the minus/–
jumper cable 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 pole.
5.Attach the second terminal clamp of the
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.
If necessary, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
Tow-starting, towing away
Observe the applicable laws and regula-
tions for tow-starting and towing
vehicles.<
Do not transport any passengers other
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.<

Release the cover panel in the bumper:
Press on the recess at the bottom center in the
cover panel.
Being towed
Make sure that the ignition is switched on,
refer to page50; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.
If the electrical system fails, do not tow-start or
tow the vehicle. The electrical steering wheel
lock cannot be released and the vehicle cannot
be steered. Jump-starting, refer to page219.
Power steering assistance is not available when
the engine is not running. Thus, braking and
steering will require increased effort.<
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever positions, refer
to page54.
Do not exceed a towing speed of 31 mph
or 50 km/h and a towing distance of
31 miles/50 km; otherwise, the automatic
transmission may be damaged.<
7-gear sport automatic transmission
with dual clutch
Ensure that transmission lock P is not
engaged as the rear wheels will otherwise
be blocked.
When using the car wash function, refer to
page209, note that the parking lock P is
engaged automatically after approx. 30 min-
utes, blocking the rear wheels.
If an electrical malfunction occurs or if towing
takes longer than approx. 20 minutes, manually
release the parking lock, refer to page58.<
Do not exceed a towing speed of 31 mph
or 50 km/h and a towing distance of
31 miles/50 km; otherwise, the 7-gear sport
automatic transmission may be damaged.<
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise, dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle; otherwise, it may
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.<

Giving and receiving assistance
222
With a 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.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
With a tow truck
Manual and automatic transmission:
7-gear sport automatic transmission with dual
clutch:
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump-start the engine, refer to
page219. Vehicles with a catalytic converter
should only be tow-started when the engine
is cold.
Vehicles with an automatic transmission or 7-
gear sport automatic transmission with dual
clutch cannot be tow-started at all.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on the ignition, refer to page50.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch completely again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
