\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.
Warning
G
Exhaust fumes are produced while the aux-
iliary heating is in operation. For this rea-
son, switch off the auxiliary heating in
enclosed spaces without an extraction sys-
tem, e.g. a garage.
Operation of the auxiliary heating system is
prohibited at gas stations or when refueling
your vehicle. The auxiliary heating must
therefore be switched off at refueling sta-
tions.
Warning
G
Observe the relevant safety regulations in
the case of vehicles used for the transport
of hazardous 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.

Auxiliary heating/ventilation*

The auxiliary heating heats the coolant
and the vehicle interior and is therefore
more favorable to the engine and con-
sumes less fuel. The fuel tank must be at
least a quarter full to ensure that the
auxiliary heating/ventilation operates
correctly.
The maximum heating period is
60 minutes.
You can use the auxiliary heating / ven-
tilation to:\4
ventilate or preheat the vehicle inte-
rior and to de-ice the windows
\4
start the engine better in cold weath-
er
\4
support the vehicle’s heating system
while the engine is running and out-
side temperatures are low (heater

page 234)
You can use the operating system to de-
fine up to three switch-on times, one of
which can be selected to switch on the
auxiliary heating / ventilation
(
\2
page 240).You can switch the auxiliary heating /
ventilation on and off immediately using:
\4
the auxiliary heating / heater booster
switch (

iThe auxiliary heating automatically
switches to heater booster mode af-
ter the engine is started.
!
CAUTION
Switch on the auxiliary heating at reg-
ular intervals (at least once a month)
for approximately 10 minutes.
Make sure that the hot air flow is not
obstructed. The auxiliary heating
would otherwise overheat and switch
off.

If you plan to operate your vehicle in for-
eign countries, please be aware that:\4
service facilities or replacement
parts may not be readily available,
\4
unleaded gasoline for vehicles with
catalytic converters may not be
available; the use of leaded fuels will
damage the catalysts,
\4
gasoline may have a considerably
lower octane rating, and improper
fuel can cause engine damage.
You will find information about
gasoline / diesel in the “Technical data”
section (
\2
page 610).You can permanently limit the maximum
speed of your vehicle to 75 mph
(120 km/h).
The manufacturer recommends that you
have the maximum speed programmed
at an authorized Sprinter Dealer. This
has the necessary specialist knowledge
and tools to carry out the required work.
Operating the vehicle outside the
USA or Canada
iIf you are traveling in countries
where vehicles are driven on the op-
posite side of the road to that in
which the vehicle is registered, you
must have the headlamps:\4
partially masked (halogen head-
lamps)
\4
switched over (bi-xenon head-
lamps)
Relevant information can be ob-
tained at an authorized Sprinter Deal-
er.

You will find information about the
speed limit for your tires under “Tires
and wheels” in this section
(\2
page 383).
Check regularly, e.g. weekly or when re-
fueling:
\4
the vehicle lighting
\4
the condition of the tires
(\2
page 346) and the tire pressures
(
\2
page 361)
\4
the engine oil level (

Your vehicle is equipped with monolith-
ic-type catalytic converters, an impor-
tant element in conjunction with the
oxygen sensors to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Service Booklet.
Warning
G
Exceeding the permissible maximum
speed can cause tire damage, which
could lead to loss of control of the vehi-
cle.
As the driver, you must find out about the
maximum speed of the vehicle and the re-
sulting permissible maximum speed of
the tires (tire and tire pressure).
Never exceed the speed limit for your
tires under any circumstances
(\2page 383).

Your vehicle is equipped with an oxida-
tion catalyst, an important element in
conjunction with the oxygen sensors to
achieve substantial control of the pollut-
ants in the exhaust emissions. Keep
your vehicle in proper operating condi-
tion by following our recommended
maintenance instructions as outlined in
your Service Booklet.
!
CAUTION
To prevent damage to the catalytic
converters, only use premium un-
leaded gasoline in this vehicle.
Any noticeable irregularities in en-
gine operation should be repaired
promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.
Warning
G
As with any vehicle, do not idle, park or
operate this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could
be ignited and cause a vehicle fire.
