CLIMATE
Parking heater*
The parking heater heats the passenger com-
partment as necessary before driving if the car's
preconditioning is activated.
The parking heater is one of two subfunctions of
the car's heater. The heater is fitted in the front
right-hand wheel housing.
When this symbol illuminates in the
driver display, the parking heater may
be active.
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.
The parking heater starts automatically if the
parking climate's preconditioning* is activated
and the passenger compartment needs to be
heated up.
It switches off automatically when a set timer
time or the heater's maximum run time expires, or
if the car is restarted.
The heater's maximum running time is
30 minutes.

NOTE
Make sure there is enough fuel in the car's
fuel tank if the parking heater needs to be
used.
Make sure that there is enough charge in the
starter battery if the parking heater needs to
be used.
IMPORTANT
Repeated use of the parking heater combined
with short journeys may discharge the battery
and impair starting.
If the heater is used on a regular basis, then
the car should be driven for the same amount
of time that the heater is used in order to
ensure that the car's battery is recharged with
the same amount of energy as consumed by
the parking heater.
WARNING
Do not use preconditioning if the car is equip-
ped with a heater*:
In unventilated spaces indoors. Exhaust
•
gases are emitted if the heater starts.
In locations with combustible or flamma-
•
ble material nearby. Fuel, gas, long grass,
sawdust, etc. may ignite.
When there is a risk that the heater's
•
exhaust line may be blocked. For exam-
ple, deep snow inside the front right-hand
wheel housing can obstruct the heater's
ventilation.
Remember that the preconditioning can be
started by a timer that has been set for a long
time in advance.
WARNING
If there is a smell of fuel, unusual amounts of
smoke, black smoke, or unusual sounds com-
ing from the parking heater, switch off the
heater and, if possible, pull out its fuse. Volvo
recommends that an authorised Volvo work-
shop should be contacted for repair.
