Activating the perfume atomizer/ionization
(see separate COMAND operating instruc-
tions).
Setting the departure time You can set the departure time using the
instrument cluster or via the "Vehicle Home-
page" (Y
page 220). The activation of the
"Pre-entry climate control at departure time"
function can be linked to this departure time.
Your vehicle will then be cooled or heated
until the desired temperature is reached in
time for the set departure time. "Pre-entry
climate control at departure time" will be acti- vated a maximum of 55 minutes before
departure. If the departure is delayed, the
vehicle will be heated or cooled for a further
five minutes.
X To set the departure time: set the depar-
ture time via the instrument cluster. To set the departure time via the "Vehicle Home-
page" (Y page 220).
X To activate/deactivate "Pre-entry cli-
mate control at departure time": acti-
vate/deactivate "Pre-entry climate control
at departure time" via COMAND (see sep-
arate operating instructions). To activate/ deactivate the "Pre-entry climate control at
departure time" function via the Vehicle
Homepage (Y page 220).
When activating the "Pre-entry climate con-
trol at departure time" function: you can
select whether only the driver's area or the
whole vehicle interior should be heated or
cooled.
The "Pre-entry climate control at departure
time" function switches off automatically
when the vehicle is started. The following
functions remain active:
R Seat heating
R Seat ventilation
R Armrest heating
R Steering wheel heating
R Perfume atomizer

Switching off "Pre-entry climate control
at departure time": the activated "Pre-entry
climate control at departure time" can be
switched off using the rocker switch
(Y page 183).
Activating/deactivating "Immediate
pre-entry climate control" using the
rocker switch You can activate "Immediate pre-entry cli-
mate control" even if the vehicle interior is
already at the desired temperature. This
means that the vehicle interior continues to
be cooled or heated, e.g. if the journey is
interrupted for up to 50 minutes, and the inte-
rior temperature is kept constant. Operating the climate control systems

Important safety notes
G
WARNING
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:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior. Setting the center air vents

The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain further informa-
tion about this from your authorized
Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal. Keep this in mind, and adapt
your driving and braking accordingly during
this break-in period.
Excessive heavy braking results in corre-
spondingly high brake wear. Observe the
brake wear warning lamp in the instrument
cluster and note any brake status messages
in the multifunction display. Especially for
high performance driving, it is important to
maintain and have the brake system checked regularly. Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
R you drive at low speeds.
R the tires have adequate tread depth. For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
R lower your speed.
R avoid ruts.
R avoid sudden steering movements.
R brake carefully.
Driving on flooded roads !
Do not drive through flooded areas.
Check the depth of any water before driving through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic compo-
nents in the engine or the automatic trans- mission. Water can also be drawn in by the
engine's air suction nozzles and this can
cause engine damage. Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind. 228
