Check Control
The concept The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys‐
tems monitored.
A Check Control message consists of indicator and warning lamps in the instrument cluster
and, in some circumstances, an acoustic signal
and text messages at the top of the Control
Display.
Indicator/warning lamps
The indicator and warning lamps can light up in
a variety of combinations and colors.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
The symbol indicates that Check Control
messages have been stored. The Check Con‐
trol messages can be displayed later.
Text messages Text messages at the upper edge of the Con‐
trol Display in combination with a symbol in the
instrument cluster explain a Check Control
message and the meaning of the indicator and
warning lamps.
Supplementary text messages
Addition information, such as on the cause of a
fault or the required action, can be called up via
Check Control.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
Symbols
The following functions can be selected within
the supplementary text message, depending
on the Check Control message.▷ "Service request"

▷Some Check Control messages are dis‐
played continuously and are not cleared
until the malfunction is eliminated. If sev‐
eral malfunctions occur at once, the mes‐
sages are displayed consecutively.
These messages can be hidden for approx.
8 seconds. After this time, they are dis‐
played again automatically.▷Other Check Control messages are hidden
automatically after approx. 20 seconds.Seite 85DisplaysControls85

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.

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

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
Online Edition for Part no. 01 40 2 918 395 - III/13
system activated, resting your foot on the acel‐
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.◀

ating3Interrupting and deactivating the system4Resuming a speed stored beforehand
Maintaining current speed
Push, arrow 1, or pull, arrow 2, the lever to the
resistance point.
The car's current speed is stored and main‐ tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.Seite 118ControlsDriving comfort118
