Only have work on the vehicle carried out
by a BMW Sports Activity Vehicle Center
or a repair shop that works in accordance with
BMW guidelines and uses appropriately trained personnel. Otherwise, there is the risk of life-
threatening injury by electrocution due to the
high voltage of the hybrid system.<

Giving and receiving assistance
Jump starting, charging
high-voltage battery
Your BMW ActiveHybrid X6 is equipped with
two types of battery:
>12 Volt battery
>High-voltage battery
If the 12 Volt battery or high-voltage battery is
dead, the combustion engine can be started
with the aid of another vehicle using two jumper
cables.
Only use jumper cables with fully insulated ter-
minal clamps and do not deviate from the
described procedure.
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 injuries.<
Identifying the dead battery
>Dead 12 Volt battery: Ignition cannot be
switched on.
>Dead high-voltage battery: Ignition can be
switched on. Drive readiness cannot be
activated.
A message appears on the Control Display.
Preparation
1.Check whether the battery of the other
vehicle is a 12 Volt battery and has approxi-
mately the same capacitance in Ah. This
information can be found 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.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
In your BMW, the so-called jump-starting termi-
nal in the engine compartment functions as the
positive battery terminal, also refer to the
engine compartment overview on page35. The
cover cap is marked with a + symbol.
1.Fold open the cover of the BMW starting-
aid terminal. To do so, pull the tab.
2.Attach one end of the jumper cable plus/+
to the positive terminal of the battery or a
starting-aid terminal of the vehicle provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a start-
ing-aid terminal of the vehicle to be started.
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 assisting
vehicle.
Your BMW has a special nut as body ground
or negative pole.

Giving and receiving assistance
38 5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Charging: 12 Volt battery
1.Start the engine on the assisting vehicle
and activate drive readiness, allowing the
assisting vehicle to run at idle for several
minutes at slightly increased speed.
2.Start the engine on your vehicle in the usual
way.
If the first starting 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 connection sequence.
Have the battery checked if necessary.
Never use spray fluids to start the
engine.<
Charging: High-voltage battery
1.Start the engine on the assisting vehicle
and activate drive readiness, allowing the
assisting vehicle to run at idle for several
minutes at slightly increased speed.
2.Switch on the ignition of your vehicle when
prompted by the corresponding message
on the Control Display. The charging
begins.
3.The charging is concluded when this is
prompted by a corresponding message on
the Control Display.
4.Start the combustion engine of your own
vehicle.
5.Disconnect the jumper cables by reversing
the connection sequence.
Have the hybrid system checked if necessary.
Never use spray fluids to start the
engine.<
Charging interrupted
The charging may be interrupted, for example if
the battery power of the assisting vehicle is
insufficient.
Disconnect the jumper cables in the reverse of
the sequence described above and contact
your BMW Sports Activity Vehicle Center.
Tow-starting and towing
Getting towed:
Have your BMW ActiveHybrid X6 trans-
ported only on a flat bed of a tow truck;
otherwise, the high-voltage system may be
damaged.<
In special circumstances, it is possible to have
the vehicle towed on the road for short dis-
tances, e.g. in order to remove the vehicle from
a dangerous area.
No tow-starting
The engine cannot be started by tow-starting.
Start the engine by jump starting it, refer to
page37.
Have the cause of the starting difficulties elimi-
nated.
Towing the vehicle
Towing your BMW ActiveHybrid X6 with a tow
rope or tow bar is only possible in special cir-
cumstances for short distances, e.g. in order to
remove the vehicle from a dangerous area. Oth-
erwise, the hybrid system can be damaged.
