Cruise control*
The concept
The cruise control with a braking function is
available for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle stores and
maintains the speed that you set using the lever
mounted on the steering column. To keep the
specified speed constant, the system brakes if
the engine braking effect is not sufficient on a
downhill grade.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads, in heavy traffic or in poor road conditions
such as snow, rain, ice, and loose road surface.
Otherwise you could lose control of the vehicle
and cause an accident.<

Maintaining current speed
Briefly press, arrow1, or briefly pull, arrow2
lever.
The speed currently being driven is stored and
maintained. It is indicated on the speedometer
and briefly in the instrument panel.
The controlled speed can drop on uphill grades
if the engine output is insufficient. If the engine
braking effect is not sufficient on a downhill
grade, the system lightly brakes the vehicle.
Increasing speed
Repeatedly press the lever up to or beyond the
resistance point, arrow1, until the desired
speed is set.
>Each time the lever is pressed to the resis-
tance point, the speed is increased by
approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond
the resistance point, the desired speed
increases by a maximum of 5 mph or
10 km/h.
The system stores the setting and maintains
the set speed.

Rear view camera*
The concept
The rear view camera in the liftgate displays the
area behind your vehicle on the Control Display.
Also check the traffic situation around the
vehicle during parking and maneuvering
with direct vision, as otherwise danger of an
accident could result, for example, from road
users or objects located outside the picture
area of the rear view camera.<

Driver assistance functions
The following functions can improve the effect
of the rear view camera depending on the situa-
tion.
They can only be activated when the tailgate
and liftgate are completely closed.
Pathway lines
The pathway lines are shown in the picture of
the rear view camera. They help you to estimate
the space required when parking and maneu-
vering on level roads.
To estimate the space required, turn the steer-
ing wheel so that the pathway lines guide into
the parking space or the maneuvering area you
have chosen.
The pathway lines are dependent on the current
steering angle and are continuously adjusted to
the steering wheel movements.
Turning lines
The static turning lines are displayed in the pic-
ture of the rear view camera and show you the
course of the smallest possible turning circle on
level roads.

Using pathway and turning lines
1.Position the vehicle so that the turning lines
guide within the limits of the parking space.
2.Turn the steering wheel so that the pathway
lines cover the corresponding turning lines.
This results in a steering wheel position that
makes full use of the smallest possible turning
circle of the vehicle when parking.
Virtual camera panning
The displayed picture area is dependent on the
current speed:
At low speeds, the camera view is panned
toward the street, and at higher speeds toward
the horizon.
This enables the currently relevant picture area
to be shown enlarged on the Control Display.
To activate the virtual camera panning, select
the camera view "Camera view: full screen",
refer to Displays on page88.
Obstacle marking
Spatially shaped markings are shown in the pic-
ture of the rear view camera. Their stepped col-
ors correspond to the markings of the Park Dis-
tance Control and support you in estimating the
distance to the object shown.
The obstacle marking is deactivated when driv-
ing in reverse from approx. 12 mph/20 km/h.

Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page129.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

Malfunction of driving stability control
systems
When driving on poor roads, avoid using
full throttle or pressing the accelerator
beyond the kick-down point and also avoid
heavy braking. Otherwise, the drive train may be
damaged or accidents can occur.<
Adaptive Drive*
The concept
Adaptive Drive reduces the body roll which
occurs when cornering quickly or during fast
evasive maneuvers. In addition, Adaptive Drive
also reduces the steering angle requirement,
improves the running comfort and increases
the dynamic driving characteristics of your X5.
Chassis and suspension tuning

Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
If you have deactivated DSC, it will be activated
automatically.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.If the vehicle is not equipped with run-
flat tires as provided at the factory,
refer to page239, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident. In the event
of pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact the BMW
Sports Activity Vehicle Center.<
