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 cli-
mate control's preconditioning is activated.
•
Additional heater - heats the passenger
compartment and engine, if necessary, dur-
ing driving.
The heater is fuel-driven and is fitted in the front
right-hand wheel housing.
NOTE
When the heater is running, smoke may be
emitted from the right-hand front wheel hous-
ing 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 per-
fectly normal.
Battery and charging
The heater is powered by the car's starter battery.
If the charge level of the starter battery is too low,
then the heater is switched off automatically and
the driver display shows a message.
NOTE
Make sure that there is enough charge in the
battery if the heater needs to be used.
Fuel and refuelling
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.
