2021 VOLVO V90 CROSS COUNTRY jump start

MAINTENANCE AND SERVICE
602
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.
