Warning triangle*
The warning triangle is conveniently stored in
the onboard tool kit mounted on the inside of
the luggage compartment lid.
First-aid kit*
The first-aid kit is also located in the container
of the onboard tool kit.
Some of the articles contained in the first-aid kit
have a limited service life. Check the expiration
dates of the contents regularly and replace the
contents concerned in a timely fashion as
needed.
Jump starting
When your battery is discharged, you can use
two jumper cables to start your vehicle with
power from the battery in a second vehicle. You
can also use the same method to help start
another vehicle. Use only jumper cables with
fully-insulated terminal clamps.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible personal injury.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
This information is listed on the battery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.
Make sure that there is no contact
between the bodywork of the two vehi-
cles; otherwise, there is a danger of short cir-
cuits.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting jum-
per cables.<
In your BMW, the so-called jump starting termi-
nal in the engine compartment functions as the
positive battery terminal. The symbol + is
embossed on the cover.
1.Remove the cover of the BMW jump start-
ing terminal, refer to arrow1.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a jump starting terminal of the
vehicle providing assistance.
3.Attach the second positive/+ clamp of the
jumper cable to the positive battery terminal
or to a jump starting terminal on the vehicle
to be started.
4.Attach one negative/– clamp of the jumper
cable to the negative battery terminal or to
an engine or body ground of the assisting
vehicle.

arrow2.
5.Attach the second negative/– clamp of the
jumper cable to the negative battery termi-
nal or to an engine or body ground on the
vehicle to be started.
Starting engine
1.Start the engine of the assisting vehicle and
allow it to run for several minutes at a fast
idle.
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.Allow the engines to run for several min-
utes.
4.Disconnect the jumper cables again in the
reverse sequence.
If need be, have the battery checked and
recharged.
Never use spray fluids to start the
engine.<
Towing and tow starting
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
The threaded tow fitting is stored in the
onboard tool kit and must always remain in the
vehicle. It can be screwed in at the front or rear
of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do not lift the vehicle by the tow fitting. Otherwise,
damage to the tow fitting and the vehicle can
occur.<
Access to screw thread
Press the arrow symbol to push out the cover.
Being towed
Do not tow the vehicle by the rear axle;
because there is no steering lock, the
wheels could turn to an extreme angle during
towing. There is no power assist with the
engine stopped. This then requires increased
effort for braking and steering.<
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.
Selector lever in position N. Releasing
shiftlock manually, refer to page64. To
avoid damaging the automatic transmission, do
not exceed a towing speed of 45 mph/70 km/h
and a towing distance of 95 miles/150 km.<
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle must not be lighter
than the vehicle to be towed; otherwise,
it will no longer be possible to control vehicle
response.<
