Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and rec-
ommendations to help you use the air-condi-
tioning system optimally.
RSwitch on the air-conditioning system by turn- ing control knob Aclockwise to the desired
position (except position 0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for avoiding misted
windows at low exterior temperatures or
in rain: switch on the ¿cooling with dehu-
midification function (
Ypage 114).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 115).
Deactivate air-recirculation mode e
(
Ypage 118).
Set airflow control Ato a setting between 3
and 6(
Ypage 116).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3and
6 (
Ypage 116).
RRecommendation for a constant vehicle
interior temperature: set airflow controlA
to a setting between 1and 3(
Ypage 116).
RRecommendation for air distribution in
winter: select the Oand¯ settings
(
Ypage 115).
Recommendation for air distribution in
summer: select the PorP and¯
settings (
Ypage 115).
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 tu
nnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display; see separate operating
instructions. You will see the current settings
of the various climate control functions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles)
You can choose between various drive programs
with the DYNAMIC SELECT button
(
Ypage 127).
If you have selected drive program E:
Rwhen heating, the electrical heater booster is
deactivated and in the warming-up phase
heat output is reduced
Rthe rear window defroster running time is
reduced
Depending on the configuration, climate set-
tings may also be influenced in the drive pro-
gram I.
If you have selected drive program Cor S, cli-
mate settings are not influenced.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 126).

GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
General notes
During a cold start, the engine runs at higher
speeds to enable the catalytic converter to
reach its operating temperature. The sound of
the engine may change during this time.
Automatic transmission
XShift the transmission to position P
(Ypage 129).
The transmission position display in the mul-
tifunction display shows P(
Ypage 129).
iYou can start the engine in transmission
position Pand N.
Starting procedure with the SmartKey
To start the engine using the SmartKey instead
of the Start/Stop button, pull the Start/Stop
button out of the ignition lock.
XTurn the SmartKey to position 3in the ignition
lock and release it as soon as the engine is
running (
Ypage 121).
Starting procedure with the Start/Stop
button
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 automatic engine start func-
tion.
You can start the engine if a valid SmartKey is in the vehicle. Switch off the engine and always
take the SmartKey with you when leaving the vehicle, even if you only leave it for a short time.
Pay attention to the important safety notes.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(Ypage 121).
The engine starts.
Starting procedure via smartphone
Observe the important safety notes on starting
the engine (Ypage 122).
You can also start your engine via your smart-
phone from outside the vehicle. In this case, the
previously selected climate control setting is
activated. In this way you can cool or heat the
interior of the vehicle before starting the jour-
ney.
Only start the engine via your smartphone if it is
safe to start and run the engine where your vehi-
cle is parked.
Observe the legal stipulations in the area where your vehicle is parked. Engine start via smart-
phone may be limited to certain countries or
regions.
You can execute a maximum of two consecutive
starting attempts via your smartphone. If you
insert the SmartKey into the ignition lock, you
can carry out two more starting attempts.
Once you have started the engine, you can
switch the engine off via your smartphone at any
time.
You can only start the engine via your smart-
phone if:
Rthe SmartKey is in the ignition lock
Rpark position Pis selected
Rthe accelerator pedal is not depressed
Rthe anti-theft alarm system is not activated
Rthe panic alarm is not activated
Rthe hazard warning lamps are switched off
Rthe hood is closed.
Rthe doors are closed and locked
Rthe windows and sliding sunroof are closed

ProblemPossible causes/consequences andMSolutions
The engine does not
start. You cannot hear
the starter motor.The on-board voltage is too low because the battery is too weak or
discharged.
XJump-start the vehicle (Ypage 273).
If the engine does not start despite attempts to jump-start it:
XConsult a qualified specialist workshop.
The starter motor was exposed to a thermal load that was too high.
XAllow the starter motor to cool down for approximately two minutes.
XTry to start the engine again.
If the engine still does not start:
XConsult a qualified specialist workshop.
The engine is not running
smoothly and is misfir-
ing.There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
gauge shows a value
above 248 ‡ (120 †).
The coolant warning
lamp may also be on and
a warning tone may
sound.The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 257). Observe the warning notes
as you do so and add coolant if necessary.
