G
Risk of injury
Very hot or very cold air can flow from the air
vents. This could cause burns or frostbite to
bare skin in the immediate vicinity of the
vents. Keep bare skin away from these air
outlets. If necessary, direct the airflow away
to a different 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 grille on the bonnet free
of blockage, such as ice, snow or leaves.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior. i
For virtually draught-free ventilation,
adjust the sliders of the air vents to the
centre position.

Risk of accident
Make sure that all windows are clear of ice
and snow before starting a journey. This may
otherwise obstruct your view of the traffic
conditions, thereby causing an accident.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.
i If the battery voltage is too low, the rear
window heating may switch off.

tion mode
You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.

of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the engine has been switched off. The heating
time depends on the temperature that has

Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore Air conditioning

switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using the vehicle's
fuel. For this reason, the tank content must
be at least at reserve fuel level to ensure that
the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 107). Switching the auxiliary heating/venti-
lation on/off using the button on the

Roof rack system*
G
Risk of accident and injury
An incorrectly secured roof rack, ski rack or
load could become detached from the vehi-
cle. These objects may be thrown around and
can injure you or others, or cause an accident.
Follow the roof rack/ski rack manufacturer's
installation instructions and special instruc-
tions for use.
The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must always observe the maximum roof
load of 100 kg. Always adapt your driving style
to the prevailing road, traffic and weather
conditions and drive with particular care if the
roof is laden.
! Mercedes-Benz recommends that you
only use roof rack systems which have
been tested and approved for Mercedes-
Benz vehicles. This helps to prevent dam-
age to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle's equipment,
make sure that you can:
R raise the sliding/tilting sunroof* fully
R open the tailgate fully X
Secure the roof carrier to roof rails :.
Observe the manufacturer's installation
instructions. Cross bar To make it easier to attach the cross bars,
there are marks on the roof rails. These indi-
cate the best positions for fitting the cross
bars. :

! Note that fitting the crossbar increases
the vehicle height by 50 mm compared to
the data in the "Technical Data" section. Features
Sun visors
G
Risk of accident
Keep the mirrors in the sun visors covered
while driving. Otherwise, you could be daz-
zled, impairing your view of traffic conditions.
As a result, you could cause an accident. Features
