When thest ationary heater is swit ched on,
parts of theve hicle can become very hot, e.g.
th est ationary heater exhaust sy stem.
Flammable materials such as lea ves, grass or
twigs may ignite if they come into contact
wi th:
R hot parts of thest ationary heater exhaust
sy stem
R theex haust gas itself
There is a risk of fire. #
When thest ationary heater is swit ched
on, make sure that:
R Hot vehicle parts do not come into
contact with flammable materials.
R The exhaust gas can flow out of the
st ationary heater exhaust pipe
unhindered.
R The exhaust gas does not come into

Fu
nction of the hot- water auxiliary hea ter
The hot-water auxiliary heater complements your
ve hicle's climate contro l system, and has a
heater boos ter,auxiliary heating and auxiliary
ve ntilation function. In addition, the auxiliary
heating sy stem heats the engine coolant topro‐
te ct the engine and sa vefuel during thewa rming-
up phase. The auxiliary heating heats the air
inside theve hicle tothe set temp erature. It is not
dependent on the heat output of theru nning
engine. The auxilia ryheating is operated directly
using theve hicle's fuel. Forth is reason, the fuel
ta nk must ha vebeen filled abo vethere ser vefuel
le ve l so that the auxiliary heating can work. The
auxilia ryheating automatically adapts its operat‐
ing mode tothe outside temp erature and
we ather. It is therefore possible that the auxiliary
heating may switch from ventilation toheating
mode or from heating toventilation mode. When
th e engine is running, auxilia ryventilation is not
acti ve.Au xilia ryheating automatically switches
itself off af ter a maximum of 50 minutes. Yo u
cannot use the "auxiliary ventilation" ope rating
mode tocool the air inside theve hicle tobelow
th e outside temp erature. Auxilia ryheating helps
to heat up theve hicle while the engine is running
and at low outside temp eratures.
Operating the hot-wa ter auxiliary heater draws
po we r from theve hicle batter y.Therefore, drive a
re asonably long dis tance af ter heating or ventilat‐
ing theve hicle twice in succession at most.
Au xilia ryheating can be activated only at temp er‐
atures below 40 °F (4.5 °C).

Ifth e trailer has electronically cont rolled
brakes, pull away carefully wi th theve hicle/
trailer combination. Brake manually using the
brake controller and check whe ther the
brakes are functioning cor rectly.
R Secu rethe load on the trailer in line with the
re qu irements and rules for load-securing
me thods.
R When driving with a trailer, check at regular
inter vals that the load is secure and that the
lights and brakes are functioning cor rectl y.
R Bear in mind that the handling characteristics
are more uns table when towing a trailer than
when driving without a trailer. Avoid sudden
st eering mo vements.
R The vehicle/trailer combination is heavier,
accelerates more slowl y,has a reduced
climbing ability and an increased braking dis‐
ta nce. It is more susceptible toside winds
and requ ires careful steering.
R If possible, do not brake suddenl y,but rath er
moderately at firs t so that the trailer can acti‐
va te its brakes. Then inc rease the pressure on
th e brake pedal.
R Ifth e automatic transmission shifts between
ge ars on uphill or downhill gradients, restrict
th e shift range. Select shi ftrange 4, 3, 2 or 1.
A lo werge ar and reduced speed decrease the
ri sk of engine damage.
R When driving on a downhill gradient, shift to a
lo we rge ar to use the engine's braking ef fect.
Av oid cons tant braking, as this could cause
th eve hicle brakes and possibly also the
trailer brakes toove rheat.
R Ifth e coolant temp erature increases signifi‐
cantly when the air-conditioning sy stem is
switched on, switch the air-conditioning sys‐
te m off.
Coolant heat can also be dissipated by
switching the air flow and thete mp erature of
th e heater or air conditioning tothe maximum
le ve l. Open the windo wsif necessar y.
R When overtaking, pay particular attention to
th e increased overtaking di stance of your
ve hicle/trailer combination.

Comply with the permissible gross com‐

rve hicles with a permissible gross vehicle
we ight of 11030 lbs (5003 kg),th e permissible
gross combination weight is less than the sum of

trailer is fully laden, the permitted gross vehicle
we ight or the permitted trailer load values are

partially load the trailer or theve hicle.
The gross trailer weight (G TW) is calculated by
adding thewe ight of the trailer tothewe ight of
th e load and equipment. If the trailer is equipped
with a separate braking sy stem, then the maxi‐
