control system. The indicator

The climate control is operational whenever
the engine is running. You can operate the
climate control system in either the
automatic or manual mode. The system cools
or heats the interior depending on the
selected interior temperature and the current
outside temperature.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
( Y page 169).
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
Keep the air intake grille in front of the
windshield free of snow and debris.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” (Y page 102). The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
GWarning!
When the climate control system is switched
off, the outside air supply and circulation are
also switched off. Only choose this setting for
a short time. Otherwise the windows could fog

Notes on 3-zone automatic climate
control
With the help of a sun sensor, the automatic
climate control determines the relation of the
sun to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
The automatic climate control is operational
whenever the engine is running. It cools the
vehicle’s interior according to the angle and
intensity of the sun’s rays, the outside
temperature and the selected temperature.
You can operate the automatic climate
control in either the automatic or manual
mode.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.

Make sure any children traveling with you do
not injure themselves or start a fire with the
hot cigarette lighter.

! The lighter socket can be used to
accommodate 12V DC electrical
accessories (up to a maximum of 180 W)
designed for use with the standard
“cigarette lighter” plug type. Keep in mind,
however, that connecting accessories to
the lighter socket (for example extensive
connecting and disconnecting, or using
plugs that do not fit properly) can damage
the lighter socket. With the socket
damaged, the lighter may not function
properly any longer.
! The cigarette lighter is not designed for
use with the electric air pump. Use the
power outlet in the second-row footwell for
electric air pump operation.
Power outlets
iYou can use the power outlets even if the
ignition is switched off.
An emergency shut-off feature is designed
to prevent the vehicle’s on-board voltage
from dropping below a minimum level. If
the on-board voltage drops to this
minimum level, the power outlets are
automatically switched off, to help
preserve engine starting power.
12V Power outlets
! If you use all power outlets in the vehicle,
make sure that the maximum current
drawn does not exceed 55 A.
! The power outlets in the front passenger
footwell and cargo compartment are not
designed for use with the electric air pump.
Use the power outlet in the second-row
footwell for electric air pump operation.
The power outlets can be used to
accommodate 12V DC electrical accessories
(e.g. mobile phone chargers, auxiliary lamps)
up to a maximum of 20 A (240 W).
