Using energy recovery
Energy recovery is displayed in the instrument
panel.
Coasting mode
In coasting mode, e.g. when rolling toward a
traffic signal, the high-voltage battery is
charged by energy recovery.
Braking
The most efficient energy recovery and charg-
ing of the high-voltage battery are achieved
with moderate braking.
Switching off functions currently not
required
Functions such as air conditioning, seat heat-
ing, or rear window defrosting consume a lot of
energy and require additional fuel. Their influ-
ence is particularly pronounced in city traffic
and stop & go operation. For this reason, it is a
good idea to switch these functions off when
they are not really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW Sports
Activity Vehicle Center. Also pay attention to
the BMW maintenance system, refer to the
BMW X6 Owner's Manual.
General driving notes
Driving through water
Maximum water depth: 17 in/45 cm
Only drive through water up to the above-
mentioned depth at no greater than walk-
ing speed; otherwise, the engine, electrical sys-
tem, and transmission can be damaged.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure.<
With a fully charged high-voltage battery,
the combustion engine is switched on
when driving downhill in order to avoid over-
loading the high-voltage battery.<
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page18. This prevents an
excessive strain on the brakes.
Do not drive in idle or with drive readiness
mode deactivated; otherwise, there is no
braking action from the energy recovery or from
the engine and no power-assistance for braking
and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<

ried out only by your BMW Sports Activity Vehi-
cle Center or a repair shop that works according
to BMW repair procedures with correspond-
ingly trained personnel.
Have maintenance and repair on the vehi-
cle carried out only by your BMW Sports
Activity Vehicle Center or a repair shop that
works in accordance with BMW guidelines and
uses appropriately trained personnel. Other-
wise, there is the risk of life-threatening injury
by electrocution due to the high voltage of the
hybrid system.<
Never touch the high-voltage compo-
nents of the hybrid system; otherwise,
there is the risk of life-threatening injury by
electrocution due to the high voltage of the
hybrid system.<
Do not remove the cover panel of the
cargo bay floor; otherwise, the high-volt-
age battery could be damaged.<
12 Volt batteries
Battery care
The 12 Volt batteries are maintenance-free, i.e.
the electrolyte will last for the life of the battery
when the vehicle is operated under temperate
climatic conditions. Your BMW Sports Activity
Vehicle Center will be glad to advise in all mat-
ters concerning the battery.
Charging batteries
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page37.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always restrain the
battery to prevent it from tipping over during
transport.<

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.

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.

Giving and receiving assistance
40 trained personnel. Otherwise, there is the risk of
life-threatening injury by electrocution due to
the high voltage of the hybrid system.<
Hybrid system: Contact with water
The hybrid system is generally safe, even in the
following sample situations:
>Water in the footwell, e.g. when rain show-
ers occur with an open glass roof.
>The vehicle is in water, e.g. in a flood.
>Fluid escapes in the cargo bay.
In these cases, there is no danger of being
injured by electrocution. Other types of damage
to the vehicle are possible.
Hybrid system: Automatic deactivation
In the event of an accident, the hybrid system is
switched off automatically in order to protect
passengers and other road users from injury.
The high-voltage system is automatically
switched off in the following sample situations:
>Sensors of the airbag system detect an
accident
>Obstacles on the road damage the under-
body and high-voltage cables
After an accident, do not touch any
exposed high-voltage components. Oth-
erwise, there is the risk of life-threatening injury
by electrocution due to the high voltage of the
hybrid system.<
