drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when- ever a drive wheel spins due to insufficient
grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. PARKTRONIC
G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It does not relieve you of
the responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasound. It assists you when parking by
displaying the distance between your vehicle
and an obstacle. It also emits a warning tone
when you approach an obstacle.
PARKTRONIC is activated automatically when
you switch on the ignition, release the electric
parking brake or start the engine and shift the
automatic transmission to D,Ror N. Driving systems

G
Risk of accident
The reversing camera is only an aid and may
display obstacles in a distorted or incorrect
manner, or may not even display them at all.
The reversing camera does not relieve you of
the responsibility to pay attention. The cam-
era cannot show objects:
R very near to the rear bumper
R below the rear bumper
R in the area immediately above the boot lid
handle
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. This applies to the areas
behind, in front of and next to the vehicle. You
could otherwise endanger yourself and oth-
ers. G
Risk of accident
Under the following circumstances, the
reversing camera will not function, or 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 light (the dis-
play may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event have the camera position and setting
checked at a qualified specialist workshop.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose.
Do not use the reversing camera in these
types of situation. You could otherwise injure others or damage objects and your vehicle
while you are parking.
Activating the reversing camera X
Make sure that the key is in position 2in
the ignition lock.
X Engage reverse gear.
The area behind the vehicle is shown in the
COMAND display with guide lines. G
Risk of accident
Please note that objects not on ground level
may appear to be further away than they
actually are. These include:
R the bumper of the vehicle parked behind
R trailer tow bars
R the tail-end of a lorry
R slanted posts
The lines are only guides, not accurate meas-
urements of the distance to an obstacle.
Therefore, you should never pass the red line
when approaching an obstacle. You could oth-
erwise cause an accident and injure yourself
and others. Red guide line
=, approximately 0.25 m, and
yellow guide line ;, approximately 1.0 m,
show the approximate distance from the rear
end of the vehicle. Blue line :depicts the
width required for the vehicle. It helps you to
position the vehicle at the side of the road,
e.g. at the kerb. 258

Night View Assist*
Night View Assist uses infrared as well as the
normal headlamps to light up the road. A
camera at the top of the windscreen picks up
the infrared light and displays a black and
white image in the multi-function display. The
image shown in the multi-function display
corresponds to a road lit up by main-beam
headlamps. This enables you to see the road's
course and any obstacles in good time. G
Risk of accident
Night View Assist is only an aid designed to
assist driving and does not relieve you of the
responsibility to pay attention. Continue to
look through the windscreen instead of rely-
ing on the Night View Assist display. You are
responsible for safety and must drive in
accordance with traffic conditions. You could
otherwise endanger yourself and others.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R you drive around a bend or up or down an
incline.
Light from the headlamps of oncoming vehi-
cles does not affect the Night View Assist dis-
play. This is also the case if you cannot switch
on the main-beam headlamps because of
oncoming traffic. G
Risk of accident
Night View Assist does not detect objects in
the immediate vicinity of the vehicle. Look
through the windscreen when manoeuvring.
Make sure that there are no people or animals
in the area in which you are manoeuvring.
i Infrared light cannot be seen by the
human eye and therefore does not dazzle. Night View Assist can always remain on,
even if there is oncoming traffic.

General notes
The automatic air conditioning controls the
temperature and the humidity of the vehicle
interior and filters out undesirable substan-
ces from the air.
The automatic air conditioning is only opera-
tional when the engine is running. 31
Optimum
operation is only achieved when you drive
with the side windows and sliding/tilting sun-
roof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 201).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
31 The "residual heat" function can only be switched on/off if the ignition is switched off. 262

Switching the auxiliary heating/ven-
tilation* on/off
Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using the vehicle's
fuel. For this reason, the tank content must
be at least at reserve fuel level to ensure that
the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. Before activating X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the rocker switch on the centre console.
You can use COMAND (Y page 172) or the
remote control to specify up to three depar-
ture times, one of which may be preselected.
