BMW ActiveHybrid X6
The concept
Through the interplay of the combustion engine
and electric motors, your BMW ActiveHybrid X6 achieves a particularly efficient fuel consump-
tion and optimizes vehicle performance.
Components of the system
1High-voltage battery
2High-voltage wires: orange
3Two-Mode Active Transmission with 2
integrated electric motors
4Combustion engine
5Control-system electronics
Do not damage orange high-voltage
wires. Otherwise, there is the risk of fatal
injury by electrocution. is stored in the high-voltage battery stored
under the luggage compartment floor in the
luggage compartment.
To produce electrical energy, the two electric
motors in the Two-Mode Active Transmission
function as generators. They are driven by the
combustion engine or by kinetic energy during
braking.
This permits an energy conversion of kinetic
energy into electrical current.

Do not run the combustion engine in
enclosed spaces; otherwise, the inhala-
tion of toxic exhaust gases can cause loss of
consciousness and death. The exhaust gases
contain carbon monoxide, an odorless and col-
orless, but highly toxic gas.
Never leave the vehicle unattended with the
combustion engine running; such a vehicle rep-
resents a potential safety hazard.<
Deactivating drive readiness
When drive readiness is switched off, the
tachometer pointer is in the OFF position.
When leaving the vehicle, always take
along the remote control.
Set the parking brake firmly when parking; oth-
erwise, the vehicle could roll.<
After the vehicle is switched off, audible operat-
ing sounds may issue from the hybrid system,
e.g. the cooling of the high-voltage battery.
Procedure
1.Select transmission position P with the
vehicle stationary.
2.Press the Start/Stop button.
3.Set the parking brake.
4.Remove the remote control from the igni-
tion lock.

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
page18.
Automatic shifting may be perceptible
when decelerating at a low speed.<

or N only when drive readiness is activated.
>With the vehicle stationary, depress the
brake pedal before shifting out of P or N;
otherwise the shift command will not be
executed: shiftlock.
Hold the brake pedal down until start-
ing to drive; otherwise, the vehicle can
begin to move.<
Shifting into D, R, N
Briefly press the selector lever in the desired
direction, beyond a resistance point if neces-
sary. When shifting out of P or into R, simulta-
neously push the unlock button1.
The engaged transmission position is displayed
on the selector lever.
The selector lever immediately returns to the
center position when released.
Shifting into P
Press buttonP.When the vehicle is stationary and the
transmission is in the R, D, or M/S posi-
tion, if you disconnect the driver's seat safety
belt and open the driver's door without stepping
on any of the pedals, then the transmission
shifts into position P.<
R Reverse
Select only with the vehicle stationary.
An interlock prevents inadvertent gearshifts
into transmission position R. To release the
lock, push the unlock button1.
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.<
P Park
Select only with the vehicle stationary. The rear
wheels are locked.
The transmission automatically shifts into
P as soon as you switch off the engine.
Unless position N is selected and the remote
control is in the ignition lock.<
N Neutral
Can be selected in automatic car washes, for
example. The vehicle can roll.
The transmission remains in N even after
the engine is switched off whenever you
leave the remote control in the ignition lock.
This function is used, for example, in a car wash,
refer to page15. After approx. 30 minutes P is
automatically engaged.<
Shifting into N
It is possible to select N even when the ignition
is switched on.

D Drive, automatic position
Position for normal vehicle operation. All for-
ward gears are shifted automatically. Depend-
ing on operating conditions, the vehicle is
driven electrically or with the combustion
engine.
The fuel consumption is the lowest in transmis-
sion position D.
Kick-down
The kick-down mode provides maximum accel-
eration.
Press the accelerator pedal beyond the
increased resistance at full throttle.
Due to the high power requested, the combus-
tion engine is started and is assisted by the
electric motors as needed.
Sport program and manual mode M/S
Press selector lever out of transmission
position D toward the left:
The sport program is activated, S and the
engaged gear are displayed in the instrument
panel. This position is recommended for a per-
formance-oriented driving style.
With the sport program activated, the combus-
tion engine is always started.
When the selector lever is pressed forward or
back, the manual mode is activated and the
Steptronic shifts the gear. For example, M3 is
displayed in the instrument panel.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system. The selected gear is briefly displayed in the instru-
ment panel, followed by the current gear.
To use the automatic function again, press the
selector lever to the right into position D.
Changing gears using shifting paddles
on steering wheel
The shifting paddles make it possible to quickly
change gears since both hands can remain on
the steering wheel.
>Upshifting: pull on one of the shifting pad-
dles, arrows +.
>Downshifting: press on one of the shifting
paddles, arrows –.
The gear change using the shifting paddles can
be executed in automatic mode D or in manual
mode M/S.
When the shifting paddles are actuated during
electric driving, the combustion engine starts.
Changing gears in manual mode M/S
With manual mode activated, gear changes are
executed using the shifting paddles or the
selector lever.
With the transmission position M/S selected,
the manual mode remains active.
Changing gears in automatic mode D
Even in automatic mode D, gear shifts can be
executed using the shifting paddles.
The combustion engine starts.
Then if a certa in amount of time pas ses witho ut
a gear change being executed using the shifting
paddles or a corresponding acceleration, then
the transmission returns to automatic shifting
of the forward gears.

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.
