You can activate the cruise control if the
vehicle speed is above 20 mph (30 km/h).
In the following cases you cannot activate
the cruise control:


when you brake


the vehicle is secured with the elec-
tronic parking brake


when the automatic transmission is set
to park positionP, reverse gear R, or
neutral positionN


when ESP
® is switched off
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses when the cruise con-
trol engages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
i
The vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.

DISTRONIC Plus*
When activated, the DISTRONIC Plus adap-
tive cruise control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.

If the DISTRONIC Plus distance sensor
detects a slower moving vehicle direct-
ly ahead, your vehicle speed will be re-
duced so that you follow that vehicle at
your preset following distance.


If there is no vehicle directly ahead of
you, DISTRONIC Plus will function in
the same way as standard cruise con-
trol (
page 437).
DISTRONIC Plus functions within a speed
range of 0 to 120 mph
(Canada: 0 to 200 km/h).When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 302).
Canadian law does not permit the use of
the radar sensor system* (
page 302) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:

Warning!
G
DISTRONIC Plus is a convenience system.
Its speed adjustment reduction capability is
intended to make the cruise control more ef-
fective and usable when traffic speeds vary.
It is not however, intended to, nor does it, re-
place the need for extreme care. The re-
sponsibility for the vehicle speed and the
distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
DISTRONIC Plus cannot take street and traf-
fic conditions into account.
Complex driving situations are not always
fully recognized by DISTRONIC Plus. This
could result in wrong or missing distance
warnings.

Parktronic system malfunction
If only the red distance segments illumi-
nate and an acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.

Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.
If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty or
there is an interference from other radio or
ultrasonic signals. The Parktronic system
will automatically switch off after 20 sec-
onds and the indicator lamp in the
Parktronic switch comes on.

Park Assist is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver.Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.!
Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g.
trailer couplings, painted posts, elevated cross-
bars or road curbs). Such objects may not be
detected by the system and can damage the
vehicle.

The Park Assist system deactivates at
speeds over approximately 10 mph
(16 km/h). At lower speeds the Parktronic
system turns on again.
Park Assist is also switched off when you
set the automatic transmission to park
positionP or switch off the engine.
While the transmission is in neutral
positionN, Park Assist is switched off if
you secure the vehicle in place with the
electronic.
The Park Assist system monitors the sur-
roundings of your vehicle with four sensors
in the front bumper and two sensors in the
rear bumper.
Range of the sensors
The sensors of the Park Assist system are
integrated in the front and rear bumpers.
Make sure that the bumpers are clear of
dirt, ice and slush in the area of the sen-
sors, as otherwise, Park Assist may not
function properly, see “Cleaning the driv-
ing systems sensors” (
page 601).Front sensors

Due to the sensors’ broad detection range,
it is possible that Park Assist also detects the fol-
lowing obstacles and issues a warning:


obstacles in the ground, e.g. sewer canal
covers, rails, bumps in the road or gutters


obstacles moving upward quickly, e.g. rolling
garage doors

While parking, pay particular attention to ob-
jects over or underneath the sensors, e.g. flower
boxes, an elevated crossbar or a trailer tow
hitch. Park Assist does not detect such nearby
objects. You could otherwise damage the vehicle
or the objects.

470 Controls in detailDriving systemsWarning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle.
The warning indicator for the front area is
in the instrument cluster. The warning indi-
cator for the rear area is on the roof liner in
the rear.
1Left side of the vehicle
2Right side of the vehicle
3Readiness indicator
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
If yellow readiness indicators 3 under the
distance segments are lit, Park Assist is
ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.


Front area:
As soon as the first red distance seg-
ment comes on, you will hear an inter-
mittent warning tone for approximately
2 seconds. Once the second red dis-
tance segment comes on, you will hear
a continuous warning tone. You have
reached the minimum distance.


Rear area:
As soon as the first red distance seg-
ment comes on, you will hear an inter-
mittent warning tone for approximately
2 seconds. Once the second red dis-
tance segment comes on, you will hear
a continuous warning tone. You have
reached the minimum distance.

Collision warning
Park Assist can detect obstacles from a
considerable distance. If you drive in re-
verse towards an obstacle, you will hear a
warning tone. You must then brake in or-
der to avoid a collision. The warning tone
for a collision will not sound when the vehi-
cle is at a standstill very close to the obsta-
cle. In this case, you will hear a
corresponding tone for the warning indica-
tor in the rear area.

Advanced Parking Guidance*
Advanced Parking Guidance is an electron-
ic parking aid equipped with radar sensors
that scan the area on both sides of vehicle.
When suitable parking space is found it is
shown in the display and you receive steer-
ing instructions for parking in that space.
i
During strong rainfall, the collision warning
may be triggered, for example, by water splash-
ing into the area of the sensors.
i
When the indicator lamp is illuminated, the
Park Assist system is switched off.
i
The Park Assist system is automatically
switched on when the ignition (
page 365) and
radar sensors are switched on (page 302).
Warning!
G
Advanced Parking Guidance is only an aid
and may display parking spaces that are not
suitable e.g. due to parking regulations, un-
suitable road/ground surfaces, driveways,
entrances/exits, etc.


473 Controls in detail
Driving systems
Use Advanced Parking Guidance for park-
ing spaces that are

parallel to the direction of travel


located on straight streets, i.e. not in
curves


on the same level as the street, i.e. not
on sidewalks, for example. Flat curbs
may possibly not be detected by Ad-
vanced Parking Guidance.
Parking instructions:


On narrow streets, drive by the parking
space as close as possible.


Parking spaces that are dirty, over-
grown or located in front of trailers may
not be detected correctly.


Also observe the Park Assist warning
indicator (
page 470) while Advanced
Parking Guidance is active.


How well your vehicle will be parked af-
ter completion of the Advanced Park-
ing Guidance depends on the position
and shape of the vehicles parked in
front of and behind the parking space
as well as the conditions of the imme-
diate surroundings. In certain cases,
Advanced Parking Guidance may guide
you too far into the parking space or
not far enough. If this is the case, can-
cel the parking procedure with Ad-
vanced Parking Guidance and correct
the vehicle position yourself.Detecting a parking space
Advanced Parking Guidance is active when
driving forward. The system operates at a
vehicle speed of up to 25 mph (40 km/h)
and automatically scans for and measures
potential parking spaces on both sides of
the vehicle. At a vehicle speed of below
10 mph (16 km/h), you see the white
parking space symbol as a system display
in the instrument cluster. As soon as Ad-
vanced Parking Guidance has detected a
suitable parking space, the parking space
symbol changes to blue.
