Heater
The heater has two subfunctions that help to
heat the passenger compartment or engine in
different situations.
The heater has two subfunctions:
•
Parking heater - heats the passenger com-
partment, if necessary, when the parking
climate control's preconditioning is acti-
vated.
•
Additional heater - heats the passenger
compartment and engine, if necessary,
during driving.
Either a fuel-driven heater or a high-voltage
heater is used, depending on the market.
12
The heater is fitted in the front right-hand
wheel housing.
NOTE
When the heater is running
13
, smoke may
be emitted from the right-hand front wheel
housing and a low hum may be heard. A
ticking sound from the fuel pump may also
be heard from the rear section of the car.
This is perfectly normal.
Battery and charging
The heater is powered by the car's hybrid bat-
tery. If the charge level of the hybrid battery is
too low, then the heater is switched off auto-
matically and the driver display shows a mes-
sage.
NOTE
Make sure that there is enough charge in
the battery if the heater needs to be used.
The car must be connected to an electrical
socket for the heater to be used for pre-
conditioning.
Fuel and refuelling
14
Warning label on fuel filler flap.
The heater uses fuel from the car's normal fuel
tank.
If the car is parked on a steep hill, the front of
the car should point downhill to ensure that
there is a supply of fuel to the heater.
If the level in the fuel tank is too low then the
heater is switched off automatically and the
driver display shows a message.
NOTE
Make sure there is enough fuel in the car's
fuel tank if the heater needs to be used.
WARNING
Fuel which spills out could be ignited.
Switch off the fuel-driven heater before
starting to refuel.
Check in the driver display that
the heater is switched off. This
symbol is lit when it is working as
a parking heater.
