betwee n0mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distanc ePilot DISTRONIC on roads
with steep gradients.
As Distanc ePilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities .You can refertot he
relevant chapter in the Operator's Manual if
questions are asked about this.

Important safety notes
GWARNING
Distanc ePilot DISTRONIC does not react to:
Rpeople or animals
Rstationar yobject sont he road, e.g. stopped
or parked vehicles
Roncomingv ehicles and crossingt raffic
As aresult,D istancePilot DISTRONIC may
neither give warnings nor intervene in such
situations .There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Distanc ePilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases ,Distanc ePilot DISTRONIC may:
Rgive an unnecessary warnin gand then

There is arisk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distanc ePilot DISTRONIC
warns you.
GWARNING
Distanc ePilot DISTRONIC brakes your vehicle
with up to 50% of the maximum possible
deceleration. If this deceleratio nisnot suffi-
cient, Distanc ePilot DISTRONIC alertsy ou
with avisual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and tr ytot akee vasivea ction.
!When Distanc ePilot DISTRONIC or the
HOL Dfunction is activated, the vehicle
brakes automatically in certain situations.

Settingaspecified minimum distance
You can set the specified minimum distance for
Distanc ePilot DISTRONIC by varying the time
span between one and two seconds. With this
function, you can set the minimum distance that
Distanc ePilot DISTRONIC maintains to the vehi-
cle in front,d ependent on the vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 145).
The specified minimum distance can be
changed while Distanc ePilot DISTRONIC is
switched on or off.
Make sure that you maintain asufficiently safe
distance from the vehicle in front.A djust the
distance to the vehicle in front if necessary.

!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on atruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automaticallyw hen
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
:Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them (
Ypage 240).

Parking Guidance
Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. Asuitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You may also use PARKTRONIC
(
Ypage 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. When maneuvering, parking or
pulling out of aparking space, make sure that
there are no persons, animals or object sinthe
area in which you are maneuvering.
GWARNING
If object sare located above the detection
range, Parking Guidance may provide steering
instructions too soon. You may cause acolli-
sion as aresult. There is arisk of an accident.
If object sare located above the detection
range, stop and switch off Parking Assist.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Use Parking Guidance for parking spaces:
Rthat are paralleltot he direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.

alimited manner:
Rif the trunk lid is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbsorL ED
lighting (the displaym ay flicker)

Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at aqualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, bicycle rack).
For technical reasons, leaving the standard
height can result in inaccuracies in the guide
lines on vehicles with aheight-adjustable chas-
sis.
iThe rear view camera is protected from rain-
drops and dust by means of aflap. When the
rear view camera is activated, this flap opens.
The flap closes againw hen:
Ryou have finished the maneuvering process
Ryou switch off the engine
Ryou open the trunk
Observe the notes on cleaning (

For technical reasons, the flap may remain
open briefly after the rear view camera has
been deactivated.
Activating/deactivating the rear view camera
XTo activate: make sure that the SmartKey is
in position 2in the ignition lock.
XMake sure that the Activation byRgearfunction is selected in the multimedia system;
see the Digital Operator's Manual.
XEngage reverse gear.
The rear view camera flap opens. The multi-
media system shows the area behind the vehi-
cle with guide lines. The image from the rear view camera is avail-
able throughout the maneuvering process.
To deactivate: the rear view camera deacti-
vates if you shift the transmission to Por after
driving forwards ashort distance.
