Accelerate slightly:
Press the lever up to the resistance point,
arrow1, until the desired speed is reached.
Accelerate more rapidly:
Press the lever beyond the resistance point,
arrow1, until the desired speed is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores the
setting and maintains the set speed.
Reducing speed
Repeatedly pull the lever up to the resistance
point or beyond, arrow2, until the desired
speed is displayed.
>Each time the lever is pulled up to the resis-
tance point, the desired speed decreases
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
decreased by a maximum of 5 mph or
10 km/h until the minimum speed of
20 mph or 30 km/h is reached.
The system stores the setting and maintains
the set speed.
Deactivating cruise control
Briefly press the lever up or down, arrow3.
The displays in the speedometer go out.
In addition, the system is automatically deacti-
vated:
>when braking
>when transmission position N is engaged
>when DTC is activated or DSC is deacti-
vated
>when HDC is activated
>when the parking brake is set
>when driving stability control systems inter-
vene
Accelerating does not deactivate the cruise
control. After releasing the accelerator pedal,
the stored speed is reached and maintained

xDrive
xDrive is the 4-wheel drive system of your X5.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately walking speed without active
intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately walking
speed, approx. 5 mph/8 km/h, and then main-
tains this speed at a constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 4 mph/6 km/h to
15 mph/25 km/h.You can specify a target speed within the same
range by using the lever of the cruise control.
With downhill grade over 10Ξ you can reduce
the speed to approx. 3 mph/4 km/h. Pull the
lever of the cruise control beyond the resis-
tance point, arrow3.
1Increasing speed
2Pull to the resistance point:
Reduce speed to approx. 4 mph/6 km/h
3Pull beyond the resistance point:
With downhill grade over 10Ξ, reduce
speed to approx. 3 mph/4 km/h.
Activating HDC
Press the button; the LED lights up.
The HDC display is shown in the instrument
panel.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again. The LED and the HDC
display go out.
HDC is also deactivated at speeds over approx.
37 mph/60 km/h.

Integrated universal remote
control*
The concept
The integrated universal remote control can
replace as many as three hand-held transmit-
ters for various remote-controlled accessories,
such as garage and gate or lighting systems.
The integrated universal remote control regis-
ters and stores signals from the original hand-
held transmitters.
The signal of an original hand-held transmitter
can be programmed on one of the three mem-
ory buttons1. Then with the ignition switched
on, this programmed memory button1 can be
used to operate the respective feature. The
LED2 flashes to confirm transmission of the
signal.
Should you sell your vehicle one day, be sure to
delete the stored programs beforehand for your
safety, refer to page116.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control, always inspect
the immediate area to make certain that no peo-
ple, animals or objects are within the travel
range of the device. Also, comply with the
safety precautions of the original hand-held
transmitter.<
Checking compatibility
If you see this symbol on the packaging
or in the manual supplied with the orig-
inal hand-held transmitter, it is safe to
assume that it is compatible with the integrated
universal remote control.
Should you have additional questions,
please contact your BMW Sports Activity
Vehicle Center or call: 1-800-355-3515.

Fixed-code hand-held transmitters
1.Switch on ignition, refer to page59.
2.When starting operation for the first time:
Press the left and right-hand memory
button1 for approx. 20 seconds until the
LED2 flashes quickly. All stored programs
are deleted.
3.Hold the original hand-held transmitter at a
distance of approx. 4 in/10 cm to 12 in/
30 cm from the memory buttons1.
The required distance between the
hand-held transmitter and the mem-
ory buttons1 depends on the relevant sys-
tem of the original hand-held transmitter
used.<
4.Simultaneously press the transmit button
on the original hand-held transmitter and
the desired memory button 1 on the inte-
grated universal remote control. The LED 2
flashes slowly at first. As soon as the LED2
flashes rapidly, release both buttons. If the
LED2 does not flash rapidly after approx.
15 seconds, alter the distance and repeat
the step.
5.To program other original hand-held trans-
mitters, repeat steps 3 and 4.

Things to remember when driving

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 differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and vehicle speeds,
however 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.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
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 panorama glass
sunroof
An open panorama glass sunroof or open win-
dows likewise increase the drag coefficient and
therefore the fuel consumption.
Check 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.
Taking advantage of coasting
The flow of fuel is interrupted when coasting.
Switching off engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad crossings, or in traffic
jams. Even having the engine switched off for
approx. 4 seconds results in fuel savings.
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 please pay atten-
tion to the BMW maintenance system, refer to
page245.
General driving notes
Closing liftgate/tailgate
Operate the vehicle only when the tail-
gate and liftgate are completely closed.
Otherwise, exhaust fumes could enter into the
passenger compartment. gate open:
1.Close all windows and the panorama glass
sunroof.
2.Increase the air volume of the automatic
climate control to a high level, refer to
page108.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and never apply undercoating to
them. When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot tailpipes, as
otherwise there is a danger of burns.<
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tread depth on page238.
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may 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

Things to remember when driving
130 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.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
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.<
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 page65. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise there will be no
engine braking action or support of the braking
force 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.<
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.
When vehicle is parked
Condensation forms in the automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page51,
otherwise they could be damaged due to the
width of the vehicle.
Release the parking brake, particularly when
you have activated Automatic Hold, refer to
page61.
General information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
Mixed tires*
Before driving into a car wash, make sure
that the vehicle width is not too large for
the car wash, as otherwise the vehicle and the
car wash could be damaged.<
Rear window wiper
The rear window wiper can be damaged in car
washes. Take appropriate protective measures;
ask the car wash operator if necessary.
With comfort access*
Insert the remote control into the ignition lock.
The engine can be switched off in transmission
position N, also refer to page37.
