for instance a compact wheel: have the
service center check it if necessary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.▷Disturbance by systems or devices with
the same radio frequency: after leaving the
area of the disturbance, the system auto‐
matically becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv‐
er's responsibility to maintain correct tire pres‐
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal‐
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the in‐
stallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en‐
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Lane departure warning
The concept This system issues a warning at speeds above
approx. 40 mph/65 km/h if the vehicle is about
to leave the lane on roads with lane markings.
The steering wheel begins vibrating lightly.
The time when the warning is issued may vary
with the current driving situation.
The system does not issue a warning if the
turn signal is set before leaving the lane.Seite 102ControlsSafety102

Issuing a warning
If the vehicle begins leaving the lane and a lane
marking has been detected, the steering wheel
begins vibrating.
If the turn signal is set before the lane is
changed, a warning is not issued.
Canceling a warning The warning is canceled:
▷Automatically after approx. 3 seconds.▷After the vehicle returns to its lane.▷During heavy brake application.▷When the turn signal flashes.
System limits
Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel; otherwise, you may lose control
over the vehicle.◀
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of worn, poorly visible, merg‐
ing, diverging, or multiple lane markings
such as in construction areas.▷When the demarcation lines are covered by
snow, ice, dirt or water.▷In tight curves or on narrow lanes.▷When the demarcation lines are covered by
objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield is fogged over, dirty
or covered by a sticker, etc., in front of the
interior rearview mirror.
Malfunctions

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
Online Edition for Part no. 01 40 2 918 395 - III/13
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

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 114.
