automatic BMW X5 2013 E70 Service Manual

It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
In the event of a pressure loss, the diameter
and therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐ tion of the tire inflation pressure and afterevery tire or wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
When driving with a compact wheel, the Flat
Tire Monitor is unable to function.
Status display The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.

Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains or with a compact wheel.1."Vehicle Info"2."Vehicle status"3. "Reset"4.Start the engine - do not drive away.5.Start the initialization with "Reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The warning lamp lights up red. A
message appears on the Control Dis‐
play. In addition, a signal sounds.
There is a flat tire or a major loss in tire inflation
pressure.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Do not continue driving without run-flat
tires
If the vehicle is not equipped with run-flat tires
as provided at the factory, do not continue
driving. Continuing to drive could cause severe
accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
CBC Cornering Brake
Control
When braking during curves or when braking
during a lane change, driving stability and
steering response are improved further.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistantWhen you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Dynamic Stability Control DSC
The concept
DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Do not reduce the additional safety margin
with a risky driving style, as otherwise there is
a risk of an accident.◀
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.Seite 105Driving stability control systemsControls105

greater the drive forces in the associated
wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.
Malfunction
Malfunctions are displayed via Check Control,
refer to page 85.
Hill Descent Control HDC The conceptHDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. The vehicle moves at ap‐
proximately walking speed without braking in‐
tervention by the driver.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
moving downhill at speeds below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approximately walking speed, approx.
5 mph/8 km/h and keeps it constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
The speed can be changed in the range from
approx. 4 mph/6 km/h to ap‐
prox. 15 mph/25 km/h by pressing the acceler‐
ator or brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.
On inclines over 10 %, you can reduce the
speed to approx. 3 mph/4 km/h. Pull the lever
of the cruise control beyond the resistance point, arrow 3.1Increasing speed2Pull to the resistance point: reduce the
speed to approx. 4 mph/6 km/h3Pull beyond the resistance point: on in‐
clines over 10 %, reduce the speed to ap‐
prox. 3 mph/4 km/h
Activating HDC
Press the button; the LED above the button
lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again; the LED goes out.
HDC is automatically deactivated above ap‐
prox. 37 mph/60 km/h.

2.Release the foot brake and drive away
without delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin
rolling back.◀
Self-leveling suspension The concept The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, such as due to cargo in the vehicle, this
difference is compensated very quickly. In ad‐
dition, spring motions resulting from cornering
or irregularities in the road surface are reduced
to a minimum.
The system works automatically.
Malfunctions Malfunctions are displayed via Check Control,
refer to page 85.
Active steering The concept
The active steering actively varies the steering
angle of the front wheels in relation to the
steering wheel movements. In addition, it also
varies the steering force required for steering
depending on the vehicle's speed.
When you are driving in the low speed range,
for instance in a town or when parking, the
steering angle increases, i.e., steering be‐
comes very direct. In the higher speed range,
on the other hand, the steering angle is re‐
duced more and more. This improves the han‐
dling of your vehicle over the entire speed
range.
In critical situations, the system can make tar‐
geted corrections to the steering angle pro‐
vided by the driver and thus stabilize the vehi‐
cle before the driver intervenes.
Malfunction The warning lamp lights up yellow
and a message is shown on the Con‐
trol Display. The active steering is de‐
fective or has been temporarily deac‐
tivated. At low speeds, greater steering wheel
movements are required, whereas at higher
speeds, the vehicle reacts more sensitively to
steering wheel movements. The stability-pro‐
moting intervention can also be deactivated.
Proceed cautiously and drive defensively.
Deactivation
Active steering deactivates in order to carry
out an initialization. This deactivation is dis‐
played by means of a message. The initializa‐ tion can take several minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect In the event of a defect, a corresponding text
message is displayed. Have the system
checked.Seite 110ControlsDriving stability control systems110

Driving comfortVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
Active cruise control
With active cruise control you can select a de‐ sired speed which is then automatically main‐
tained when driving on open roadways and is
varied to maintain a selected distance setting
to slower moving vehicles ahead.
Active cruise control represents a technologi‐
cal advance over the familiar cruise control and
is a welcome relief from the constant adjust‐
ment of speed that can accompany driving in
traffic on highways or other high-speed thor‐
oughfares. Especially on longer trips and in
traffic congestion, the system can reduce fati‐
gue and tension, while increasing your enjoy‐
ment of driving. Please use it safely and re‐
sponsibly.
In addition to holding a steady cruising speed,
if you encounter slower vehicles ahead, active
cruise control will, within limits, adjust your ve‐
hicle's speed automatically so that you can
flow with the traffic without having to make
constant adjustments. If, for example, while
cruising at the selected speed, you begin to
approach a slower vehicle ahead of you in the
same lane, the system will reduce your vehi‐
cle's speed to the same as that of the vehicle
ahead to maintain your selected distance set‐
ting. You can vary the following distance,
which will vary with speed. Based on your se‐
lected distance setting, the system automati‐cally decreases the throttle setting and lightly
applies the brakes if necessary. In addition, if
the vehicle ahead of you slows to a complete
stop, the system can follow this action within
the given scope and can also accelerate from a
complete stop if the vehicle ahead of you
drives off again shortly thereafter. During brak‐
ing, your vehicle brake lamps will automatically
illuminate to alert a following driver to take ac‐
tion. In addition, it may be necessary for your
vehicle to downshift the automatic transmis‐
sion to maintain the distance setting selected.
As soon as the road in front of you has no mov‐
ing vehicles, the system will accelerate to your
desired speed. This set speed is also main‐
tained on downhill grades, however the vehicle
speed can drop below the set speed when
driving uphill if the engine output is not suffi‐
cient.
Personal responsibility
Active cruise control cannot detect stop
signs, red lights, or any object that is stopped
or is blocking the road. Active cruise control is
not and must not be used as a collision avoid‐
ance/warning system. Since this active cruise
control system is a new technology and oper‐
ates differently from conventional cruise con‐
trol systems to which you may be accustomed,
it is necessary that you read all of the pages re‐
lating to this system before use. Carefully read
and observe the information on the system
limitations, refer to page 116, to obtain a good
command of the system and its range of appli‐
cations.◀
Brake pedal feel
When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.Seite 111Driving comfortControls111

Interrupting the system
Press the lever up or down and additionally de‐
press the brake if the vehicle is stationary. The
mark in the speedometer changes color and
the distance indicator goes out.
In addition, the system is interrupted:
▷When the brakes are applied.▷When the transmission position D is disen‐
gaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC is activated▷When the safety belt and the driver's door
are opened while the vehicle is stationary.▷When the system has not detected objects
for an extended period, e.g., on a road with
very little traffic without road edge line
markings.▷The radar sensor is dirty.
Active intervention if the system is inter‐
rupted
If the system is interrupted, actively intervene
by braking and, if necessary, with evasive ma‐
neuvers; otherwise, there is the danger of an
accident occurring.◀

Before leaving the vehicle
Before leaving the vehicle with the en‐
gine running, engage position P of the auto‐
matic transmission and apply the parking
brake. Otherwise, the vehicle may begin to
roll.◀
If a vehicle detected ahead of you slows to a
halt and your vehicle is also brought to a halt
by the system:▷If the vehicle ahead of you drives away,
your vehicle accelerates automatically as
long as mark 1 for the desired speed in the
speedometer is green.▷If the vehicle ahead of you drives away
when mark 1 is orange, depress the accel‐
erator briefly or press button 4.Rolling bars
in the distance indicator 3 mean that the
vehicle ahead of you has driven away.
If you are standing behind a vehicle with your
brake pedal depressed and the system is de‐
activated or interrupted:
1.Select the desired speed using the lever,
arrow 1 or arrow 2, or press button 4 to re‐
trieve a stored speed.2.Release the brake pedal.3.When the vehicle ahead of you drives
away, press on the accelerator briefly or
press button 4.

Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:▷This device may not cause harmful inter‐
ference, and▷This device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
System limits
Speed range
Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h and 110 mph/180 km/h.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited. Two-
wheeled vehicles driving ahead of you for in‐
stance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity, you should be alert at all times so that
you can intervene actively, if necessary; other‐
wise, there is the danger of an accident occur‐
ring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not respond to:▷Pedestrians or similarly slow road users.▷Red traffic lights.▷Stationary objects.▷Cross traffic.▷Approaching traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. Take action yourself, otherwise there is
a risk of an accident.◀
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
Seite 116ControlsDriving comfort116
Online Edition for Part no. 01 40 2 918 395 - III/13

tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if necessary. Take action yourself, other‐
wise there is a risk of an accident.◀
Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehi‐
cle, you yourself must react, as the system
does not react to stopped vehicles.
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly in the curve, although
curves cannot be anticipated in advance.
Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a consider‐
able delay.
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines, with
a heavy trailer or behind bumps in the road.
Driver interventions and your
responsibility
Your actions have priority at all times. When
you press on the accelerator pedal while driv‐
ing, automatic braking is not performed and
the bars in the distance display go out until you
lift your foot from the accelerator pedal. Once
you release the accelerator pedal, the desired
speed is achieved again on clear roads or the
selected distance to the vehicle ahead is main‐
tained.
Making braking possible
Anytime the driver presses down on the
accelerator pedal, any braking action by the
system is interrupted and the distance indica‐
tor goes out until the pedal is fully released. As
soon as you fully release the accelerator, the
system will again control your cruising speed
and distance setting. While driving with the
