CAUTION
•The infotainment system's energy-savingfeature may not function correctly or atall, and/or a message may be displayed ifa battery charger or jumper cables arenot connected properly.
•The negative terminal on the battery mustnever be used to connect a jumper cableor a battery charger. Only the groundpoint on the chassis may be used.
NOTE
•The service life of the start battery isshortened if it becomes dischargedrepeatedly.
•The service life of the start battery isaffected by factors such as driving condi-tions and climate. Extreme cold may alsofurther decrease the battery's startcapacity.

•When replacing the start battery anAbsorbed Glass Mat (AGM) must be used.
•When replacing the start battery, a new bat-tery with the same specifications and dimen-sions must be used. The battery should onlybe replaced by a trained and qualified Volvoservice technician.

Support battery
Vehicles equipped with Start/Stop are equippedwith two 12-volt batteries.
In addition to a heavy-duty start battery, modelswith Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The following table shows the specifications forthe support battery:
Current (V)12
Cold start capacity (ColdCranking Amperes -CCA) (A)170
Dimensions, L×W×H in.(mm)5.9×3.5×5.1(150×90×130)
Capacity (Ah)10
•When replacing the start battery or supportbattery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
•The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
•When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa-bled due to high current consumption:
•The engine will auto-start, even if the brakepedal is depressed.
The support battery does not normally requiredmore service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery ora battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a batterycharger. Only the negative connection pointin the engine compartment may be used as aground point.

NOTE
If the start battery is completely dischargedand the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery.
To help ensure auto-start, the start batteryshould be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours.
If a charger is not available, it is advisable todisable the Start/Stop function until the bat-tery is sufficiently recharged.

Fuses
The fuses help protect the vehicle's electricalcomponents from overloading or short circuits.
WARNING
Never use metal objects or fuses with higheramperage than those stated on the lists offuses. Doing so could seriously damage oroverload the vehicle's electrical system.
Orange wires may only be handled by trainedand authorized Volvo service technicians orlicensed electricians.
A number of component in the vehicle usedhigh voltage electrical current and can be verydangerous to touch.
Do not touch any components that are notclearly described in this owner's information.
If an electrical component fails to function, thismay be due to a blown fuse. If the same fuseblows repeatedly, this indicates a problem withthe component, which should be inspected by atrained and qualified Volvo service technician.
