Maintenance and service -> Support battery for Your Volvo XC60 SUV 2020

MAINTENANCE AND SERVICE  
Support battery  
Vehicles with the Start/Stop function are  
equipped with two batteries – a more power-  
ful 12 V start battery and a support battery  
that provides stronger current during the  
function's start sequence.  
The higher the current consumption in  
the vehicle, the more the alternator has  
to work and the batteries have to be  
charged = increased fuel consumption.  
When the starter battery capacity has  
dropped below the lowest permissible  
level, the Start/Stop function is disen-  
gaged.  
When the Start/Stop function is temporarily  
reduced due to high current consumption:  
If the vehicle is instead equipped with a 48 V support  
battery, it is located to the left in the cargo compart-  
ment. Only an authorized workshop may handle the  
48 V support battery.  
The engine will auto-start, even if the  
driver does not lift their foot from the  
brake pedal.  
WARNING  
The support battery does not normally require  
more service than the start battery. If you have  
any questions or concerns, consult a work-  
shop an authorized Volvo workshop is rec-  
ommended.  
High voltage may be dangerous if handled  
incorrectly. Do not touch anything on bat-  
teries that is not clearly described in this  
Owner's Manual.  
The 12 V support battery is located in a box next to  
the spring strut in the engine compartment.  
Never use a 48 V support battery to  
jump start the vehicle.  
External electrical equipment may not  
under any circumstance be connected  
to the 48 V battery.  
Only a workshop may replace or per-  
form service on the 48 V battery – an  
authorized Volvo workshop is recom-  
mended.

If the following is not observed, the Start/  
Stop function may temporarily stop work-  
ing after connection of an external starter  
battery or battery charger:  
If the starter battery has been discharged  
to the extent that the vehicle does not have  
normal electrical functions and the engine  
must then be jump-started with an external  
battery or a battery charger, the Start/Stop  
function may remain activated. If the Start/  
Stop function shortly thereafter auto-stops  
the engine, there is a huge risk that auto-  
start of the engine will fail due to insuffi-  
cient battery capacity since the battery had  
not had time to recharge.

The negative battery terminal of the  
vehicle's starter battery must never be  
used to connect an external starter  
battery or battery charger – only the  
vehicle's negative charging point  
should be used as a grounding point.

If replacing the battery, make sure you  
replace it with a battery of the same size,  
cold start capacity and type as the original  
battery (see the decal on the battery).  
If the vehicle has been jump-started or if  
there has not been enough time for the  
battery to be charged with a battery  
charger, the Start/Stop function should be  
temporarily deactivated until the battery  
has been recharged by the vehicle. At an  
ambient temperature of about +15°C  
(about 60°F), the battery must be charged  
by the vehicle for at least one hour. At  
lower ambient temperatures, the charging  
time can increase to 3-4 hours. It is advisa-  
ble to charge the battery with an external  
battery charger.

MAINTENANCE AND SERVICE  
Battery symbols  
There are warning symbols and information  
on the batteries.  
Battery recycling  
Start batteries and support batteries contain  
lead and must be recycled in an environmen-  
tally sound manner at the end of their service  
life.  
Avoid smoking, open  
flames, and/or sparks.  
Consult a workshop if you are uncertain of  
how to dispose of this type of waste an  
authorized Volvo workshop is recommended.  
Wear protective goggles.

MAINTENANCE AND SERVICE  
Fuses and fuseboxes  
Location of fuseboxes  
Replacing fuses  
All electrical functions and components are  
protected by a number of fuses in order to  
protect the vehicle's electrical system from  
damage by short circuiting or overloading.  
All electrical functions and components are  
protected by a number of fuses in order to  
protect the vehicle's electrical system from  
damage by short circuiting or overloading.  
WARNING  
1. Refer to the fuse diagram to locate the  
fuse.  
Never use a foreign object or a fuse with a  
higher amperage than that specified to  
replace a fuse. This could cause significant  
damage to the electrical system and possi-  
bly lead to a fire.  
2. Pull out the fuse and examine it from the  
side to determine if the curved metal wire  
in the fuse is intact.  
3. If the wire is broken, replace the fuse with  
a new fuse of the same color and amper-  
age.  
If any electrical component or function is not  
responding, the component may have blown a  
fuse due to temporary overload. If the same  
fuse blows repeatedly, there may be a prob-  
lem with the component. Volvo recommends  
contacting an authorized Volvo workshop to  
have the component checked.  
The illustration is generic - appearance may vary  
according to vehicle model.

WARNING  
Contact an authorized Volvo workshop for  
assistance replacing fuses not listed in the  
Owner's Manual. If fuse replacement is  
performed incorrectly, significant damage  
can be caused to the electrical system.
