Auxiliary heating/ventilation*
3
\3 Auxiliary heating/ventilation*The auxiliary heating heats or ventilates
the interior to a temperature that you have
set. The auxiliary heating can be operated
with the engine switched on or off.
The auxiliary heating is equipped with a
water heater.
The auxiliary heating heats the coolant and
the vehicle interior and is therefore more
favorable to the engine and consumes less
fuel. The fuel tank must be at least a quar-
ter full to ensure that the auxiliary heating/
ventilation operates correctly.
The maximum heating period is
60 minutes.You can use the auxiliary heating / ventila-
tion to:
\4ventilate or preheat the vehicle interior
and to de-ice the windows
\4start the engine better in cold weather
\4support the vehicle’s heating system
while the engine is running and outside
temperatures are low (heater booster
function) (\2page 137)
You can use the operating system to define
up to three switch-on times, one of which
can be selected to switch on the auxiliary
heating / ventilation (\2page 142). Warning
G
Exhaust fumes are produced while the auxilia-
ry heating is in operation. For this reason,
switch off the auxiliary heating in enclosed
spaces without an extraction system, e.g. a
garage.
Operation of the auxiliary heating system is
prohibited at gas stations or when refueling
your vehicle. The auxiliary heating must there-
fore be switched off at refueling stations.
Warning
G
Observe the relevant safety regulations in the
case of vehicles used for the transport of haz-
ardous goods.
Aerosols, gas cartridges and other pressur-
ized containers transported in the vehicle may
be highly flammable and could explode when
heated.
Make sure that the containers described are
kept away from the flow of hot air from the
auxiliary heating.
Otherwise, you could endanger yourself and
others.
iThe auxiliary heating automatically
switches to heater booster mode after
the engine is started.
158 Controls in detailTransporting
3
The load's overall center of gravity should
be as low and central as possible, between
the axles near the rear axle.
For crewbus models:
\1Always transport loads in the load com-
partment.
\1Always place loads flush against the
seat backrests of the rear bench seat.
\1Slide larger and heavier loads as far for-
ward as possible when looking in the
direction of travel. Stack items against
each other behind the rear bench seat.\1Always secure loads with suitable
transport aids or lashing materials.
As the driver of the vehicle, you are respon-
sible for ensuring that the load is secured
against slipping, tipping over, rolling or fall-
ing down, whether driving in normal traffic
situations or on poor road surfaces or as a
result of having to swerve to avoid an ob-
stacle or applying the brakes fully.Failing to secure the load in accordance
with relevant requirements and sound
practice may be a punishable offense, de-
pending on national legislation and the
consequences that arise.
For this reason, observe the legal require-
ments in all countries concerned.
Before each journey and at regular inter-
vals during longer journeys, check whether
the load is secure and take additional ac-
tion to improve any incorrect or inade-
quate safety measures.
\1Fill up any empty spaces between the
load and the load compartment walls
or wheel arches in a form-fitting man-
ner. For this purpose, use solid trans-
port aids, such as chocks, wooden
blocks or storage cushions.Load distribution!
CAUTION
Excessive loads on individual points of
the load compartment floor or load sur-
face have a negative effect on handling
characteristics and could damage the
floor covering.
iObserve the following notes:
\4Do not stack loads higher than the
upper edge of the backrests.
\4Transport loads behind seats that
are not occupied.
\4If the rear bench seat is not occu-
pied, insert the seat belts in a cross-
wise pattern into the opposite belt
buckles.Securing a load
iInformation about how to secure a
load correctly can be obtained from the
manufacturers of transport aids or
lashing materials for securing loads.
