Notes on using climate control
Automatic climate control
The following contains notes and
recommendations on optimum use of the
automatic climate control.
RSwitch on the air-conditioning system by
turning control knobclockwise to the
desired position (except position0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for preventing
fogged up windows with low outside
temperatures or rain:switchon for
the air distribution and switchand
off if possible (Ypage 128).
In air-recirculation mode, switchoff
(Ypage 131).
Set airflow controlto a setting between
3and6(Ypage 128).
RRecommendation for rapid cooling or
heating of the vehicle interior:briefly set
airflow controlto a setting between3
and6(Ypage 128).
RRecommendation for a constant
vehicle interior temperature:set airflow
controlto a setting between1and3
(Ypage 128).
RRecommendation for air distribution in
the winter:setand
(Ypage 128).
Recommendation for air distribution in
the summer:setorand
(Ypage 128).
ROnly use the "Windshield defrosting"
function briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RVehicles with COMAND:if you change the
settings of the climate control system, the
climate status display appears for three
seconds at the bottom of the screen in the
COMAND display. See also the separate
COMAND operating instructions. You will
see the currentsettings of the various
climate control functions.
ECO start/stop function
During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require the full
climate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Ypage 140).

ECO start/stopfunction
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped undercertain conditions.
The engine starts automatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
Important safety notes

you exit the vehicle, the engine is restarted
automatically.The vehicle may begin moving.
There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.

Do not hold the vehicle stationary on uphill
gradients by depressing the accelerator
pedal. Instead, only ever hold the vehicle
stationary on uphill gradients by:
Rdepressing the brake pedal
Ractivating the HOLD function
Rengaging the electric parking brake
Kickdown
AMG vehicles:kickdown is only possible in
temporary manual drive programM. For
further information on manual drive program
M(Ypage 148).
Use kickdown for maximum acceleration:
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free
Shifting the transmission repeatedly between
gearsDandRmay help to free the vehicle if
it has become stuck in slush or snow. The
vehicle's engine management system limits
the speed to a maximum of 5 mph (9 km/h)
when shifting back and forth. To shift back
and forth between transmission positionsD
andR, move the selector lever up and down
beyond the pressure point.

Driving and parking

and measures parking spaces on both sides
of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rthat are parallel or at right-angles to the
direction of travel
Rthat are parallel to the direction of travel
and at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel
and at least 39.5 in (1.0m) longer than your
vehicle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
iIn the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right-angles to the direction of travel.
Aparking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

GWARNING
Active Parking Assist merely aids you by
intervening actively in the steering. If you do
not brake there is a risk of an accident.
Always apply the brakes yourself when
maneuvering and parking.

iIn tight parking spaces, you will achieve
the best parking results by backing up as
far as possible. When doing so, also
observe the PARKTRONIC messages.

XAlways observe the warning messages
displayed by PARKTRONIC (Ypage 176).
Parking tips:
RThe way yourvehicle is positioned in the
parking space after parkingis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also engage forward gear
prematurely.The vehicle redirects and
does not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A
sensible parking position can no longer be
achieved from this position.
Exitingaparking space
In order that Active Parking Assist can
support you whenyou exit the parking space:
Rthe border of the parking space must be
high enough.Acurb is too small, for
example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvering into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
XStart the engine.
XSwitch on the turn signal in the direction
you are pulling away.
XShiftthe transmission to positionDorR.
