Engine And Passenger Compartment Heater - Volvo S80 Owner's Manual

General
Preconditioning prepares the parking heater
for the engine and passenger compartment
before departure so that both wear and
energy needs during the journey are reduced.
The heater can be started directly or with
timer.
Two different times can be selected using the
timer. Here, time refers to the time when the
car is heated and ready. The car's electronic
system calculates when heating should be
started based on the outside temperature.
Fuel-driven heater
The fuel-driven heater cannot start if the out-
side temperature exceeds 15 °C. At –5 °C or
lower the maximum running time of the heater
is 50 minutes.
WARNING
Do not use the fuel-driven heater indoors.
Exhaust gases are secreted.
NOTE
When the fuel-driven auxiliary heater is
active there may be smoke from the right-
hand wheel housing, which is perfectly
normal.
Refuelling
Warning label on fuel filler flap.
WARNING
Fuel which spills out could be ignited.
Switch off the fuel-driven auxiliary heater
before starting to refuel.
Check in the combined instrument panel
that the heater is switched off. The heat
symbol is shown when it is operating.
Parking on a hill
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 fuel-driven
heater.

Battery and fuel
If the battery has insufficient charge or if the
fuel level is too low, the heater will be
switched off automatically and a message is
shown in the display. Acknowledge the mes-
sage by pressing the indicator stalk OK but-
ton once, see page 230.
IMPORTANT
Repeated use of the heater combined with
short journeys leads to the battery dis-
charging and consequential starting prob-
lems.
The car should be driven for the same time
as the heater is used to ensure that the
car's battery is recharged adequately to
replace the energy consumed by the
heater when it is used on a regular basis.
The heater is used for a maximum of 50
minutes each time.
