MAINTENANCE AND SERVICE
622Engine compartment overview
This overview shows some service-related com-
ponents.
Some of the components included in the vehi-
cle's electric drive system are located in the
engine compartment. Exercise caution when
accessing the engine compartment and only
touch what is required for normal maintenance.
WARNING Orange wiring may only be handled by quali-
fied personnel.
WARNING
Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure.
Do not touch anything that is not clearly
described in this Owner's Manual.
Be careful when checking/filling fluids in
the engine compartment. The layout of the engine compartment may vary depend-
ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver's
side)
Washer fluid filler pipe
12 Fusebox
Air filter
Engine oil filler pipe
WARNING Bear in mind that the cooling fan (located at
the front of the engine compartment behind
the radiator) may start or continue running
automatically up to about 6 minutes after the
engine is turned off.
Always entrust engine washing to a workshop
– an authorized Volvo workshop is recom-
mended. If the engine is hot, there is a risk of
fire.
WARNING
The ignition system works with extremely high
and dangerous voltages. The vehicle electrical
system should always be in ignition mode 0
when work in being performed in the engine
compartment.
Do not touch any spark plugs or ignition coils
when the vehicle electrical system is in igni-
tion mode II or when the engine is warm.

Engine oil
For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used. Volvo recommends: If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.
CAUTION
To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.
For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.
Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.
Volvo recommends entrusting oil changes to
an authorized Volvo workshop.
Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, awarning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-
ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.
Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.
