Heater booster system (vehicles with auxiliary heating*)
The heater booster system helps the en-
gine to reach its operating temperature
more quickly after it is started, and helps
the interior to warm up more quickly.
The heater booster system switches itself
on if:
the outside temperature is below 8 °C
the coolant temperature is below
70 °C
i
The tank must be filled up to the reserve fuel
level at least to ensure the heater booster sys-
tem works.

Risk of fire and poisoning
Exhaust fumes are produced when the heat-
er booster system is in operation. Switch off
the heater booster system therefore in con-
fined spaces without an extraction system,
e.g. in garages.
Operation of the heater booster system is
prohibited at filling stations or when your ve-
hicle is being refuelled. You must therefore
switch off the engine at filling stations.
