General notes Reversing camera
:is under a flap in the
boot lid.
Reversing camera :is an optical parking
and manoeuvring aid. It shows the area
behind your vehicle with guide lines in the
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear-view mirror.
i The text shown in the COMAND display
depends on the language setting. The fol-
lowing are examples of reversing camera
displays in the COMAND display.
Important safety notes The reversing camera is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals
or objects in range while manoeuvring and
parking. Under the following circumstances, the
reversing camera will not function, or will
function in a limited manner:
R if the boot lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if the camera lens mists up, e.g. when driv-
ing into a heated garage in winter, causing
a rapid change in temperature
R if the camera lens is dirty or obstructed.
R if the rear of your vehicle is damaged. In this
case, have the camera position and setting checked at a qualified specialist workshop.
The field of vision and other functions of the
reversing camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. licence plate holder, bicycle rack).
The guide lines in the COMAND display show the distances to your vehicle. The distances
only apply to road level.
i The reversing camera is protected from
raindrops and dust by means of a flap.
When the reversing camera is activated,
this flap opens.
The flap closes again when:
R you have finished the manoeuvring proc-
ess
R you switch off the engine
R you open the boot
Observe the notes on cleaning
(Y page 350).
For technical reasons, the flap may remain
open briefly after the reversing camera has been deactivated. 220

General notes The Driving Assistance PLUS package con-
sists of DISTRONIC PLUS (Y

Blind Spot Assist (Y page 236) and Active
Lane Keeping Assist (Y page 239).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas
on either side of the vehicle that are not visi-
ble to the driver with two lateral, rear-facing
radar sensors. A warning display in the exte-
rior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual
and audible collision warning. If a risk of side impact is detected, corrective braking may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direc-
tion of travel and to the side before making a
course-correcting brake application. For this,Active Blind Spot Assist uses the forward-
facing radar sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is
not a substitute for attentive driving. 236

Cleaning the exhaust tail pipes G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
Impurities combined with the effects of road
grit and corrosive environmental factors may cause flash rust to form on the surface. You
can restore the original shine of the exhaust
pipe by cleaning it regularly, especially in win- ter and after washing.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz. Interior care
