Heater booster system (Diesel engine)
Your vehicle is equipped with a heater
booster system. A PTC heating element
( page 475) ensures that the vehicle inte-
rior is warmed up as quickly as possible
when the engine has not reached its nor-
mal operating temperature yet.
The heater booster system switches on au-
tomatically if required.
i
If the cooling function for the air condi-
tioning is switched off with the
± button, the heater booster sys-
tem is deactivated too (Climate control
panel design A only).
