Jump starting When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the bat-
tery in a second vehicle. You can also
use the same method to help start
another vehicle. Use only jumper cables
with fully-insulated clamp handles.
To avoid the risk of potentially
fatal injury, always avoid all con-
tact with electrical components while
the engine is running. Carefully observe
the following instructions to avoid per-
sonal injury and/or damage to one or
both vehicles.<
Preparing1. 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.
To avoid personal injury from
sparks, always observe this
sequence when connecting jumper
cables.<
On your BMW the so-called jump-start
connection point in the engine com-
partment acts as the battery positive
terminal, also refer to the engine com-
partment overview on page149. The
cover cap is marked with +.
1. Fold up the cap of the BMW auxiliary
terminal for jump starting, refer to
arrow
2. Connect one terminal clamp of the
positive/+ jumper cable to the posi-
tive terminal of the battery or an aux-
iliary terminal for jump starting of the
vehicle providing starting assistance
3. Connect the second terminal clamp
of the positive/+ jumper cable to the
positive terminal of the battery or to
an auxiliary terminal for jump starting
of the vehicle to be started530de325

Jump starting Tow-starting and towing Your BMW is equipped with a special
nut on the left side panel as a body
ground or negative terminal, refer to
arrow in illustration.
4. Attach one end of the negative/–
jumper cable 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
negative terminal of the battery or to
the engine or body ground of the
vehicle to be started.530us127
Starting engine1. Start the engine on the support vehi-
cle and allow it to run for several min-
utes at a fast idle
2. Start the engine on the other vehicle
in the usual way.
If the first start attempt is not suc-
cessful, 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 connection sequence.
Depending on the cause of the fault,
have the battery recharged by your
BMW Sports Activity Vehicle center.
Never use spray fluids to start the
engine.<
Using tow fitting The screw-in tow fitting is stored
beneath the cargo floor cover. Carry it
with you at all times. It can be screwed
in at the front or rear of the vehicle.
To prevent damage to the tow fit-
ting and the vehicle, observe the
following: 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 the roadway. Avoid lat-
eral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting.<
