MERCEDES-BENZ AMG GT ROADSTER 2018 Owner's Manual

On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured
Switching Adaptive Highbeam Assist

XPress the combination switch beyond the
pressure point in the direction of arrow :.
The _ indicator lamp in the multifunction
display lights up when it is dark and the light
sensor activates the low-beam headlamps.
If you are driving at speeds above approx-
imately 16 mph (25 km/h):
The headlamp range is set automatically
depending on the distance between the vehi-
cle and other road users.
If you are driving at speeds above approx-
imately 19 mph (30 km/h) and no other road
users have been detected:
The high-beam headlamps are switched on
automatically. The Kindicator lamp in the
instrument cluster also lights up.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or other road users have been detected or the roads are ade-
quately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in the instrument cluster goes out. The
_indi-
cator lamp in the multifunction display
remains lit.
XTo switch off: move the combination switch
back to its normal position or move the light
switch to another position.
The _ indicator lamp in the instrument
cluster goes out.
Headlamps fogged up on the inside
Certain climatic and physical conditions may
cause moisture to form in the headlamp. This
moisture does not affect the functionality of the
headlamp.

Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield
may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Ractivate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The cooling with air dehumidification function is
only available when the engine is running. Opti-
mum climate control is only achieved with the
side windows closed.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 78). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the engine
has been switched off depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

Optimum use of 3-zone automatic cli-

Dual-zone automatic climate control
The following contains instructions and recom-
mendations to enable you to get the most out of
your dual-zone automatic climate control:
RActivate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with air dehumidification" function is not acti-
vated automatically in automatic mode. If
necessary, activate this function
(
Ypage 104).
RSet the temperature to 72 ‡ (22 †).
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.
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 114).
Operating the climate control sys-
tems
Setting climate control
General notes
When the climate control is switched off, the air
supply and air circulation are also switched off. The windows could fog up. Therefore, switch off
climate control only briefly
Switch on climate control primarily using the
Ã
rocker switch (
Ypage 105).
Activating/deactivating
XSelect key position 2with the Start/Stop
button (Ypage 111).
XTo switch on: set the airflow to level 1or
higher using the Hrocker switch.
XTo switch off: set the airflow to level 0using
the H rocker switch.
Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. 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.
Activating/deactivating
XPress the ¿rocker switch up or down.
The indicator lamp above the ¿rocker
switch lights up or goes out.

General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.

cally. When the manually set function switches
back to automatic mode, the indicator lamp

General notes
The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window defroster may switch off.

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.
Air vents107

Z

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
