Jump starting
If the car's own battery is flat, your BMW's
engine can be starte d 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
accident may occur. Ca refully adhere to the
following sequence, both to prevent damage
to one or both vehicles, and to guard against
possible personal injuries. <
Preparation
1.Check whether the ba ttery 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 page 255. The cap is
marked with +. 1.
Pull the cap of the BMW jump-starting
connection up to remove.
2. Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a starting-a id terminal of the
vehicle providing assistance.
3. Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a star ting-aid terminal of
the vehicle to be started.
4. Attach one terminal clamp of the minus/–
jumper cable to the nega tive 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 te rminal 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 fe w 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 be fore another attempt
in order to allow the discharged battery to

Tow-starting, towing away
Observe the applicable laws and
regulations for tow-starting and towing
vehicles.<
Do not transport any passengers other

Using a tow fitting
The screw-in tow fitting must always be carried
in the car. It can be sc rewed in at the front or
rear of the BMW.
Coupe: it is stored in the onboard vehicle tool kit
underneath the cover on the right-hand side of
the trunk, refer to page 266.
Convertible: it is stored in the onboard vehicle
tool kit underneath the trunk floor, refer to
page 266.
Use only the tow fitting provided with the
vehicle and screw it a ll the way in. Use the
tow fitting for towing on paved roads only. Avoid
lateral loading of the tow fitting, e.g. do not lift
the vehicle by the tow fitting. Otherwise, the
tow fitting and the vehicle could be damaged. <
Access to screw thread

Being towed
Make sure that the ignition is switched on,
refer to page62; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable.

MobilityGiving and receiving assistance
Do not exceed a towing speed of 45 mph
or 70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged. <
Sport automatic transmission with
double clutch
Make sure that the parking lock P is not
engaged; otherwise, the rear wheels are
immobilized.
When using the car wash function, refer to
page 263, note that the parking lock P is
engaged automatically after approx.
30 minutes, blocking the rear wheels.
In the event of an electrical malfunction or if the
vehicle must be towed for more than approx.
20 minutes, unlock the parking lock manually,
refer to page 70.<
When towing, do not exceed a maximum
speed of 30 mph or 50 km/h and a maxi-
mum distance traveled of 30 miles/50 km; oth-
erwise, the transmission may be damaged. <
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise,
damage 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 la teral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to othe r parts of the vehicle
could result in damage.<
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: vehicle without xDrive
Manual and automatic transmission:
Sport automatic transmission with
double clutch:
Have the BMW transported with a tow truck
with a so-called lift bar, or on a flatbed.
Do not tow the vehicle with just the rear axle
raised as this may cause the steering to turn.

With a tow truck: vehicle with xDrive
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 BMW transported on a flatbed surface
only.
Tow-starting
Avoid tow-starting the vehicle whenever possi-
ble; instead, jump start the engine, refer to
page 274. Vehicles with a catalytic converter
should only be tow-star ted when the engine is
cold, vehicles with an automatic transmission or
Sport automatic transmission with double
clutch cannot be tow-started at all.
1. Switch on hazard warning flashers, comply
with local regulations.
2. Switch on the ignition, refer to page 62.
3. Shift into 3rd gear.
4. Have the vehicle tow-st arted 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
warning flashers.
