Starter battery The starter battery is used to start the electri- cal system and power the starter motor andother electrical equipment in the vehicle.
The vehicle has a single-pole electrical system that uses the chassis and engine mount asconductors. The vehicle has a voltage-regulated alternating current generator. The starter battery is a 12 V battery, dimen- sioned for the carbon dioxide-reducing func-tions Start/Stop and regenerative chargingand to support the function of the vehicle'svarious systems. The service life and performance of the starter battery are affected by factors such as drivingstyle, driving conditions, climate, battery dis-charges, number of starts, etc. Never disconnect the starter battery while the engine is running.
Make sure the cables to the starter batteryare correctly connected and the clampsare securely tightened.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.
Starter battery service life and capacity
The service life of the starter battery is affec- ted by several factors, such as number ofstarts, battery discharges, driving style, drivingconditions, climate, etc. The starting capacityof the battery reduces gradually over time. Thebattery must therefore be recharged if thevehicle is not used for a long period of time orif it is only driven short distances. Severe cold further limits starting capacity. If the starterbattery becomes discharged too many times,its service life will be shortened. To help keep the starter battery in good condi- tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging. A starter battery that isalways kept fully charged has the maximumservice life.
Location
The starter battery is located in the cargo compart- ment.

MAINTENANCE AND SERVICE
601
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.

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 batterythat provides stronger current during thefunction's start sequence.
The 12 V support battery is located in a box next to the spring strut in the engine compartment.
If the vehicle is instead equipped with a 48 V support battery, it is located under the cargo compartment.The box over the 48 V support battery may only beremoved by an authorized workshop.
WARNING
High voltage may be dangerous if handled incorrectly. Do not touch anything on bat-teries that is not clearly described in thisOwner's Manual. Never use a 48 V support battery to jump start the vehicle.
External electrical equipment may notunder any circumstance be connectedto the 48 V battery.
Only a workshop may replace or per-form service on the 48 V battery – anauthorized Volvo workshop is recom-mended.
NOTE
The higher the current consumption in the vehicle, the more the alternator hasto work and the batteries have to becharged = increased fuel consumption.
When the starter battery capacity hasdropped below the lowest permissiblelevel, the Start/Stop function is disen-gaged.
When the Start/Stop function is temporarily reduced due to high current consumption: The engine will auto-start, even if the driver does not lift their foot from thebrake pedal.
The support battery does not normally requiremore service than the start battery. If you haveany questions or concerns, consult a work-shop ‒
an authorized Volvo workshop is rec-
ommended.

MAINTENANCE AND SERVICE
603
CAUTION
If the following is not observed, the Start/ Stop function may temporarily stop work-ing after connection of an external starterbattery or battery charger: The negative battery terminal of thevehicle's starter battery must
never be
used to connect an external starterbattery or battery charger – only thevehicle's negative charging pointshould be used as a grounding point.
NOTE
If the starter battery has been discharged to the extent that the vehicle does not havenormal electrical functions and the enginemust then be jump-started with an externalbattery or a battery charger, the Start/Stopfunction may remain activated. If the Start/Stop function shortly thereafter auto-stopsthe engine, there is a huge risk that auto-start of the engine will fail due to insuffi-cient battery capacity since the battery hadnot had time to recharge. If the vehicle has been jump-started or if there has not been enough time for thebattery to be charged with a batterycharger, the Start/Stop function should betemporarily deactivated until the batteryhas been recharged by the vehicle. At anambient temperature of about +15°C(about 60°F), the battery must be chargedby the vehicle for at least one hour. Atlower ambient temperatures, the chargingtime can increase to 3-4 hours. It is advisa-ble to charge the battery with an externalbattery charger.

Fuses and fuseboxes All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
If any electrical component or function is not responding, the component may have blown afuse due to temporary overload. If the samefuse blows repeatedly, there may be a prob-lem with the component. Volvo recommendscontacting an authorized Volvo workshop tohave the component checked.

Replacing fuses
All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
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.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Contact an authorized Volvo workshop for assistance replacing fuses not listed in theOwner's Manual. If fuse replacement isperformed incorrectly, significant damagecan be caused to the electrical system.
