Ionization
Ionization is used to purify the air in the vehicle
interior and attain an improved interior climate.
The ionization of the interior air is odorless and
cannot be perceived directly in the vehicle inte-
rior.
You can switch ionization on or off using the
multimedia system (
Ypage 273).
Ionization can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.
Air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-

lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and
the hood free of blockages, such as ice, snow
or leaves.
Rnever cover the air vents or air intake grilles in
the vehicle interior.
Setting the air vents
Air vents are located:
Ron the left and right-hand side of the dash-
board
Rin the middle of the dashboard
Rin the rear center console, depending on the
equipment installed

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
Vehicles with a gasoline engine: the catalytic
converter is preheated for up to 30 seconds
after a cold start. The sound of the engine may
change during this time.

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.
XTo start a diesel engine: turn the SmartKey

as the engine is running.
iVehicles with a diesel engine: you can
start the engine without preglow if the engine
is warm.
If the engine will not start:
XRemove the SmartKey from the ignition lock.
XReinsert the SmartKey into the ignition lock
after a short waiting period.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 132).

as the engine is running.
Starting procedure with the Start/Stop
button
The Start/Stop button is only available on vehi-
cles with KEYLESS-GO or the KEYLESS-GO start
function.
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 133).
Vehicles with a gasoline engine: the engine
starts.
Vehicles with a diesel engine: preglow is
activated and the engine starts.
Starting procedure via smartphone
Observe the important safety notes on starting
the engine (Ypage 133).
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.

Manual gear shifting
General notes
You can change gear yourself using the steering
wheel paddle shifters. The transmission must be
in position hto do this.
Depending on which steering wheel paddle
shifter is pulled, the automatic transmission
immediately shifts into the next gear down or
up, if permitted.
Mercedes-AMG vehicles: to use manual shift-
ing, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-
function display will show the current gear
instead of transmission position h.
If you deactivate manual gearshifting, the gears
will be shifted automatically again.
Automatic transmission145
Driving and parking
Z
When overtaking, pay particular attention to the
extended length of your vehicle/trailer combi-
nation.
Due to the length of the vehicle/trailer combi-
nation, you require additional road space when
overtaking before you can change back to the
original lane.
If the automatic transmission repeatedly shifts
between gears on uphill or downhill gradients,
shift to a lower gear.
Driving in a lower gear and at a reduced speed
decreases the risk of engine damage.
If the coolant temperature increases signifi-
cantly when climate control is switched on,
switch climate control off.
Coolant heat can also be dissipated by opening
the windows and switching the ventilation
blower and the interior temperature to the high-
est level.
Decoupling a trailer
GWARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake
is engaged.
GWARNING
Vehicles with level control:
The vehicle is lowered as soon as you discon-
nect the trailer cable. This could result in your
limbs or those of other people that are
between the vehicle body and tires or under-
neath the vehicle being trapped. There is a
risk of injury.
Make sure that nobody is in the immediate
vicinity of the wheel housings or under the
vehicle when you disconnect the trailer cable.
!Do not disconnect a trailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XApply the vehicle's parking brake manually.
XShift the transmission to position j.
XClose all doors and the tailgate.
XSwitch off the engine.
XSecure the vehicle and trailer against rolling
away.
XRemove the trailer cable.
XRemove the safety chains, if there are any.
XUncouple the trailer.
Removing the ball coupling
XObserve the manufacturer's installation
instructions.
XPress the protective cap into the ball coupling
recess.
XMake sure that the protective cap is firmly in
place.
Observe the loading guidelines (
Ypage 278)
and the safety notes regarding stowage spaces
(
Ypage 278).

Trailer power supply
!
Accessories with a maximum power con-
sumption of 180 W can be connected to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is supplied via
trailer socket pin 4.
The trailer's permanent power supply is
switched off in the event of low vehicle supply
voltage and after six hours at the latest.
A qualified specialist workshop can provide
more information about installing the trailer
electrics.
