Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
RSwitch on cooling with air dehumidification
using the ¿button. The indicator lamp
in the ¿button lights up.
RSet the temperature to 72 ‡ (22 †).
RRecommendation for air distribution in
winter: set theOand¯ settings.
Recommendation for air distribution in
summer: set thePsetting.
ROnly use the "Windshield defrosting" func-
tion 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 oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.

During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require full climate
control capacity, the ECO start/stop function can be deactivated by pressing the ECO but-

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.

iMercedes-AMG vehicles:the exhaust
flap of the exhaust system is checked after
each cold start. A resulting noise can be
heard during this process.
iDuring a cold start, the engine runs at
higher speeds to enable the catalytic con-
verter to reach its operating temperature.
The sound of the engine may change during
this time.
Automatic transmission
XShift the transmission to position P.
The transmission position display in the
multifunction display shows P.
iYou can start the engine in transmission
position Pand N.
Starting procedure with the SmartKey
To start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/Stop
button out of the ignition lock.
XTurn the SmartKey to position 3in the igni-
tion lock and release it as soon as the
engine is running (
Ypage 139).
Using KEYLESS-GO to start the engine
The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
This mode for starting the engine operates
independently of the ECO start/stop auto-
matic engine start function.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(
Ypage 140).
The engine starts.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Change gear in good time and avoid spin-
ning the wheels. You could otherwise dam-
age the vehicle.
Depress the accelerator carefully when pull-
ing away.
The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 206).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the shift
lock released.
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 161).
Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
142Driving
Driving and parking

GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or on a downhill gradient.
Rthe transmission is in position N.
Rthe electric parking brake is applied.
RESP®is malfunctioning.
ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain 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
GWARNING
If the engine is switched off automatically and
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.
