Data memory
Numerous electronic components in your vehi‐
cle contain data memories that store technical
information on the vehicle condition, events and faults, either temporarily or permanently.
This technical information generally docu‐
ments the state of a component, a module, a
system or the environment.▷Operating conditions of system compo‐
nents, such as filling levels.▷Status messages from the vehicle and its
individual components, such as wheel rpm/
speed, motion delay, transverse accelera‐
tion.▷Malfunctions and defects in important sys‐
tem components, such as lights and
brakes.▷Vehicle responses to special driving situa‐
tions, such as airbag deployment, use of
the stability control systems.▷Ambient conditions, such as the tempera‐
ture.
These data are of a technical nature only and
are used to detect and eliminate faults and to
optimize vehicle functions. Travel profiles of
routes driven with the vehicle cannot be cre‐
ated from these data. If services are used, for
instance in the event of repairs, service proc‐
esses, warranty cases, quality assurance, etc.,
this technical information can be read out from
the event and fault data memories by service
personnel, including the manufacturer, using
special diagnosis tools. This service personnel
can provide you with more information if
needed. After troubleshooting, the information
in the fault memory is cleared or overwritten
continuously.
Situations are conceivable during the use of
the vehicle in which these technical data could
become associated with a specific person in
combination with other information, such as an
accident report, damage to the vehicle, wit‐
ness accounts, etc., possibly with the involve‐
ment of an authorized expert.

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 96ControlsDriving stability control systems96

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 76.
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.

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 107, 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 102ControlsDriving comfort102

Professional navigation system
If the vehicle is equipped with a Professional
navigation system, the system adapts the ac‐
celeration and deceleration behavior of the ve‐
hicle to the road on which you are currently
driving.
To ensure that the system has the latest infor‐
mation on the course of the road, use the most
recent version of the navigation data.
If the vehicle position is unknown, e.g., if you
have left the region covered by the map, the
navigation system ceases to influence vehicle
behavior.
Applications Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it
during normal traffic.
As with conventional cruise control systems,
active cruise control in no way reduces or sub‐
stitutes for the driver's own personal experi‐
ence, responsibility, alertness and awareness
in adjusting speed, braking or otherwise con‐
trolling the vehicle. The driver should decide
when to use the system on the basis of road,
traffic, visibility, and weather conditions. Active
cruise control is intended for use on highway-
type roadways where traffic is moving rela‐
tively smoothly as well as in slow-moving traf‐
fic congestion. Do not use the system in city
driving; in complex driving situations; heavy
traffic such as during rush hour; on curvy,
winding roads, slippery roads or roads with
sharp curves such as highway off-ramps; dur‐
ing inclement weather such as snow, strong
rain or fog; or when entering interchanges,
service/parking areas or toll booths. It is also
important to regulate your vehicle's speed and
distance setting within applicable legal limits.
Always be ready to take action or apply the
brakes if necessary, especially when the sys‐
tem is actively following a vehicle in front of
you. Otherwise, driving conditions can resultwhich lead to a violation of the law or elevated
risk of an accident.
The minimum initial activation speed is
20 mph/ 30 km/h, and the maximum speed is
110 mph/ 180 km/h. The system can also be
activated while the vehicle is stationary, refer
to page 105.

erator pedal will cause the system not to brake
even if necessary. Be certain that floormats or
other objects on the vehicle floor do not inter‐
fere with movement of the acccelerator
pedal.◀
Limits of automatic braking
While active cruise control is capable of
braking your vehicle automatically when you
approach a slower vehicle ahead, it is impor‐
tant to be aware that the ability of the system
to apply the brakes is also limited, e.g. when
you reduce your desired speed sharply. lt uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or
when a much slower vehicle cuts in front of
you at close range.◀
Cruise controlThe concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
The speed specified using the lever on the
steering column is maintained.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
