Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate. Your BMW center will be
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
fold up the cover.

Giving and receiving assistance
Warning triangle*
The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard warn-
ing triangle in the vehicle.<
First-aid kit*
You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.
Therefore, check the expiration dates of the
contents regularly and replace the contents
concerned in good time if necessary. You
can find replacements in any pharmacy.
Comply with legal requirements requiring
you to carry a first-aid kit in the vehicle.<
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. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible 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 can be found on
the battery
2.Switch off the engine of the support
vehicle
3.Switch off any electrical systems and
components in both vehicles.
Ensure that no contact exists
between the bodywork on the two
vehicles, otherwise there is a danger of
short circuits.<
Connecting jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting. It is located within the engine
compartment, refer to arrow 1 in the illus-
tration. The symbol + is embossed on the
cover.
1.Remove the cover of the BMW auxiliary
terminal for jump-starting
2.Connect one terminal clamp of the pos-
itive/+ jumper cable to the positive ter-
minal of the battery or an auxiliary termi-

providing starting assistance
3.Connect the second terminal clamp of
the positive/+ jumper cable to the posi-
tive terminal of the battery or to an aux-
iliary terminal for jump-starting of the
vehicle to be started
On your BMW, there is a special nut as
body ground on the suspension strut
dome, refer to arrow2 in the illustration.
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 vehicle providing assistance
5.Connect the second terminal clamp of
the negative/– jumper cable to the neg-
ative 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 support 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 success-
ful, wait a few minutes before another
attempt in order to allow the discharged
battery to recharge
3.Allow the engines to run for several
minutes
4.Disconnect the jumper cables by
reversing the connection sequence.
If required, have the battery inspected and
recharged at your BMW center.
Never use spray fluids to start the
engine.<
Towing
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.
To avoid damage to the tow fitting
and the vehicle, observe the follow-
ing: only use the tow fitting that comes with
the vehicle and screw it in as far as it will
go. Only use the tow fitting to tow on roads.
Avoid lateral loading of the tow fitting, e.g.
do not lift the vehicle by the tow fitting.<
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 the steering detent is
not operational, 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
depending on the local regulations. If the
electrical system fails, mark the vehicle to
be towed, e.g. with a sign or warning trian-
gle in the rear window.

release of the transmission lockout,
refer to page70. Do not exceed a towing
speed of 45 mph/70 km/h and a towing dis-
tance of 90 miles/150 km, as otherwise the
automatic transmission may be dam-
aged.<
Towing methods
In some countries, towing with tow bars or
ropes in public traffic is not permitted.
Familiarize 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, other-
wise it mill not be possible to control vehi-
cle response.<
The tow fittings used should be on the
same side on both vehicles. Should it prove
impossible to avoid mounting the tow bar
at an offset angle, please observe the fol-
lowing:
>Clearance and maneuvering capability
will be strictly limited in corners
>When mounted at an angle, the tow bar
will exert lateral forces, tending to push
the vehicle sideways.
Secure the tow bar on the tow fitting
only. Otherwise damage could result
on other vehicle parts.<
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. Secure the tow rope on the
tow fitting only. Otherwise damage could
result on other vehicle parts.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a load bed.
Do not lift vehicle by tow fitting or
body and chassis parts, as otherwise
damage may result.<
