The indicator lights in the instrument cluster
light up and the mark in the speedometer is set
to the current speed.
Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press button on the steering wheel.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.
Interrupting Press button on the steering wheel.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:
▷When the brakes are applied.▷When the clutch pedal is depressed.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road withvery little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed
Press button.
Or:
Press the rocker reel while the system is inter‐
rupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.

Displays in the Head-up DisplaySome system information can also be dis‐
played in the Head-up Display.
Distance information The symbol is displayed when the dis‐
tance from the vehicle traveling ahead
is too short.▷Active Cruise Control switched off.▷Display in the Head-up Display selected,
refer to page 101▷Distance too short.▷Speed greater than approx.
40 mph/70 km/h.
System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h. The maximum speed that
can be set depends on the vehicle.
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 lidacity of the system and the
automatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because of the limited possible detec‐
tion, you should be alert at all times so that you
can intervene if needed; otherwise, there is the
risk of an accident.◀
Deceleration
The system does not decelerate for:▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.
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‐
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 needed. You must react yourself; other‐
wise, there is the risk of an accident.◀

Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding 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.◀

Pathway lines▷Pathway lines can be superimposed on the
image of the rearview camera.▷They help you to estimate how much
space is needed when parking and maneu‐
vering on level pavement.▷They are dependent on the current steer‐
ing angle and are continuously adjusted to
the steering wheel movements.
Turning circle lines
▷Turning circle lines can only be superim‐
posed on the rearview camera image to‐
gether with pathway lines.▷They show the course of the smallest pos‐
sible turning radius on a level road.▷Only one turning radius line is displayed af‐
ter the steering wheel is turned past a cer‐
tain angle.Obstacle marking
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins match the markings of
the PDC. This simplifies estimation of the dis‐
tance to the object shown.
Parking using pathway and turning
radius lines
1.Position the vehicle so that the turning ra‐
dius lines lead to within the limits of the
parking space.2.Turn the steering wheel to the point where
the pathway line covers the corresponding
turning radius line.Seite 156ControlsDriving comfort156

Parking assistant The concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
Manual transmission:
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
Steptronic transmission:
The parking assistant calculates the best pos‐
sible parking line and during the parking proce‐
dure takes control of steering, the acceleration
and braking and if needed changes the gears.
Hold down the parking assistant button for the
duration of the parking procedure. At the end
of the parking procedure, the P selector lever
position is set.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 152.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀Seite 160ControlsDriving comfort160

Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements

prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.

length of approx. 5 ft/1.5 m.▷Min. length of gap between two objects:
your vehicle's length plus approx.
4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
Regarding the parking procedure
