The individual vehicle
When purchasing your BMW, you have decided
in favor of a model with individualized equip-
ment and features. This Owner's Manual
describes the entire array of options and equip-
ment available with a specific BMW model.
Please bear in mind that the manual may con-
tain information on accessories and equipment
that you have not specified for your own vehicle.
Sections describing options and special equip-
ment are marked by asterisks
* to assist you in
identifying possible differences between the
descriptions in this manual and your own vehi-
cle's equipment.
If equipment in your BMW is not described in
this Owner's Manual, please refer to the BMW
X6 Owner's Manual.
Editorial notice
BMW pursues a policy of continuous, ongoing
development that is conceived to ensure that
our vehicles continue to embody the highest
quality and safety standards combined with
advanced, state-of-the-art technology. For this
r e a s o n , i t i s p o s s i b l e t h a t t h e f e a t u r e s d e s c r i b e d
in this Owner's Manual could differ from those
on your vehicle.
For your own safety
The BMW ActiveHybrid X6 has special fea-
tures, e.g. electric driving, that can require spe-
cial alertness in traffic.
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.<
Maintenance and repairs
Advanced technology, e.g. the use of
modern materials and high-performance
electronics, requires specially adapted mainte-nance and repair methods. Therefore, have cor-
responding work on your BMW performed only
by your BMW Sports Activity Vehicle Center or
a repair shop that works according to BMW
repair procedures with correspondingly trained
personnel. If this work is not carried out prop-
erly, there is a danger of subsequent damage
and related safety hazards. Particularly when
work is performed on the high-voltage systems,
lack of expertise can lead to life-threatening
injuries.<
Teleservice Report*
Transmits technical data about your vehicle as
needed to BMW at regular intervals; these data
are used in the development of BMW products.
The service is only used in vehicles with partic-
ular technical equipment. A Teleservice Report
is only activated in connection with the BMW
SIM card-equipped phone unit installed in the
vehicle and does not cost you anything. Neither
personal data nor location data are transmitted.

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.<

1.Open the right-hand side panel in the cargo
bay.
2.Pull the knob with the gas pump symbol.
3.Open the fuel filler door. To do this, briefly
press the lower edge.
4.Turn the fuel filler cap counterclockwise.
When the fuel tank catch is opened,
stay as far away from the vehicle as
possible since gasoline and pressurized
gasoline vapors may suddenly escape from
the fuel tank.<
Observe the following when refueling
When handling fuels, follow the safety
precautions posted at the filling station.
Otherwise, there is a danger of personal injury
or property damage.<
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Avoid raising the filler
nozzle during refueling, otherwise this leads to
>premature pump shutoff.
>a reduced efficiency of the fuel-vapor
recovery system.
The fuel tank is full when the filler nozzle clicks
off the first time.
Fuel tank capacity
Approx. 22.5 gallons/85 liters, including approx.
2.1 gallons/8 liters of reserve
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<
Fuel specifications
Gasoline engine: required fuel
Do not use leaded gasoline, otherwise
damage to the catalytic converter will
result.
Do not refuel with E85, i.e. fuel that consists of
85% ethanol, or Flex Fuel, otherwise perma-
nent damage to the engine and the fuel supply
system will result.<
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is 89.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10% ethanol or other
oxygenates with up to 2.8% oxygen by weight,
that is, 15% MTBE or 3% methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

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.

Using a tow fitting
The screw-in tow-fitting should always be car-
ried in the vehicle. It can be screwed in at the
front or rear of the BMW.
It is located in the onboard toolkit under the
floor panel flap in the cargo bay.
Use only the tow fitting provided with the
vehicle and screw it all the way in. Use the
tow fitting for towing only on roads. Avoid lateral
loading of the tow fitting, e.g. do not lift the vehi-
cle by the tow fitting. Otherwise damage to the
tow fitting and the vehicle can occur.<
Access to screw thread
Cover panel on left and right side of bumper:
press on the arrow symbol on the cover panel.

Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts, otherwise damage may
result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
Hybrid system safety
Working on the vehicle
The hybrid system of the BMW ActiveHybrid X6
is a closed system.
Safety is assured as long as no work is per-
formed on the technical components.
Therefore, have changes to and work on the
vehicle, e.g. installation of accessories, carried
out only by your BMW Sports Activity Vehicle
Center or by a repair shop that works in accor-
dance with BMW guidelines using appropriately
trained personnel.
Have maintenance and repair of the vehi-
cle carried out only by the service depart-
ment or by a repair shop that works in accor-
dance with BMW guidelines using appropriately
