Functions of the hybrid system
The hybrid system of your BMW ActiveHybrid
X6 offers the following functions.
Electric driving: eDRIVE
Under certain conditions, refer to page15, the
vehicle is powered exclusively by its electric
motors.
Driving with combustion engine: DRIVE
The combustion engine supplies the drive out-
put for moving the vehicle. The high-voltage
battery is charged at the same time.
The hybrid system always starts the combus-
tion engine automatically, refer to page16.
Assisted combustion engine: eBOOST
The combustion engine supplies the main drive
output for moving the vehicle.
In this mode, the electric motors assist the
combustion engine with additional power as

can be activated within an interval of approx. 2
to 60 seconds after radio readiness is switched
on, under the following conditions:
>driver's door closed
>conditions met to allow electric driving,
refer to page15
During electric driving, please note that
pedestrians and other road users may fail
to notice the vehicle in the usual way due to the
lack of engine noise. For example, proceed with
particular caution when pulling into and out of a
parking space.<
Starting the combustion engine
When drive readiness is switched on under the
following circumstances, the combustion
engine is started:
>drive system not at operating temperature
>high temperature of hybrid system
>insufficient charge state of high-voltage
battery or fully charged high-voltage battery
If a Silent start is not possible:
Avoid frequent starting of the combustion
engine in quick succession or repeated starting
attempts in which the engine does not start.
Otherwise, the fuel is not burned or inade-
quately burned and there is a danger of over-
heating and damaging the catalytic converter.<

Driving
Electric driving: eDRIVE
Requirements
Electric driving is possible under the following
conditions:
>driving speed:
a maximum of approx. 37 mph/60 km/h
>charge state display of the high-voltage
battery: at least 15%
>transmission in position D or R, refer to
page17
>drive system at operating temperature
>accelerator pedal not pressed down too far
>driver's door closed
Possible driving speed
The possible speed that can be reached in elec-
tric driving depends on the charge state of the
high-voltage battery.
>charge state display 15% to 40%:
maximum driving speed is approx. 25 mph/
40 km/h
>charge state display 40% to 100%:
maximum driving speed is approx. 40 mph/
65 km/h
When accelerating past a speed of 25 mph/
40 km/h, the combustion engine is started
briefly in order to assure smooth acceleration.
Indicators of electric driving in the instrument
panel, refer to page22.

Possible range
The vehicle can travel approx. 1.5 miles/2.5 km
under electric power.
Driving with combustion engine: DRIVE
The combustion engine supplies the drive out-
put for moving the vehicle. The high-voltage
battery is charged at the same time.
Automatic starting while driving
Under the following circumstances, the com-
bustion engine is started automatically while
driving:
>transmission position M/S selected
>driving speed greater than 40 mph/65 km/h
>low charge state or fully charged high-volt-
age battery, e.g. when driving downhill
>to protect the high-voltage system from
overheating, e.g. when driving downhill
>high output request, e.g. by accelerator
pedal position.
Automatic switching off while driving
When decelerating under the conditions for
electric driving, refer to page15, the combus-
tion engine is switched off.
Assisted combustion engine
The combustion engine supplies the main drive
output for moving the vehicle.
The electric motors assist by providing addi-
tional drive output as needed.
eBOOST
When accelerating quickly, e.g. when passing
another vehicle, power from the two electric
motors simultaneously is requested in addition
to that of the combustion engine. To trigger
this, step down hard on the accelerator pedal.
Display in the instrument panel, refer to
page22.
Energy recovery: CHARGE
The hybrid system makes it possible to convert
kinetic energy into electrical current, e.g. during braking. This energy recovery is used to charge
the high-voltage battery. The battery supplies
this stored energy back to the electric motors
as needed.
To recover the braking energy, the following
conditions must be met:
>The vehicle is in motion.
>The selector lever is in the position D, R, or
M/S.
>The high-voltage battery is not completely
charged.
Display of energy recovery in the instrument
panel, refer to page22
Two-Mode Active
Transmission with Steptronic
The Das Two-Mode Active Transmission is an
automatic transmission in which the gears can
be shifted in a fully automatic fashion or can be
shifted manually on demand. The manual shift-
ing is performed using the selector lever or the
shifting paddles of the Steptronic, refer to

Things to remember when driving
26
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and rear axle differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at various engine and vehicle speeds, but
do not exceed:
>4,500 rpm or 100 mph/160 km/h
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight increases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof*
An open glass sunroof or window likewise
increases air resistance and thus fuel consump-
tion.
Checking tire inflation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance and thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive at a moderate engine
speed. This is the fastest way for the cold
engine to reach its operating temperature.
Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Driving at a low engine speed reduces fuel con-
sumption and minimizes wear.

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.<

Things to remember when driving
28
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.

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.<
Also follow the instructions for what to do after
an accident.
What to do after an accident
If you should get into an accident with your
vehicle, the following safety precautions must
be taken with regard to the hybrid system:
>Secure the accident site.
>Immediately inform the paramedics, police,
o r f ir e d e p a r t m e n t o f t h e f a c t t h a t i t i s a v e h i-
cle equipped with a hybrid system.>Move the selector lever into position P, set
the parking brake, and switch off drive
readiness.
>Do not touch any orange high-voltage
cables and connectors or high-voltage
components. Otherwise, there is the risk of
life-threatening injury by electrocution.
>Do not inhale gases emanating from the
high-voltage battery. Stay away from the
vehicle if necessary.
>Contact a service center in order to ascer-
tain the damage.
