Automatically connecting to a
workshop
Without driver confirmation
This is the most convenient way to transmit trou-ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion.
If the vehicle stops at a workshop and the engineis switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driverdoes not tap the Cancel button in the message.
To help prevent the driver from being disturbedby unwanted requests to connect (e.g., if thevehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmation
With this alternative, the driver must confirm aconnection.
If the vehicle stops at a workshop and the engineis switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv-er's door is opened if the driver taps Connect inthe pop-up window. If the driver does nothing ortaps the pop-up window's Abort button, noattempt will be made to establish a connection.
NOTE
To help prevent the driver from being distur-bed by unwanted requests to connect (e.g., ifthe vehicle is often parked near a workshopwith an authorized Volvo network), the vehiclewill switch to manual connection if the drivercancels a connection request twice within5 days.
Manually connecting to a workshop
Manual connections are handled by the servicetechnician.
Changing the way a connection is made
The type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view andtap Settings.
2.Tap CommunicationVolvo ServiceNetworks.
3.Select Automatically connect when Iarrive, Ask before connecting or Neverconnect and never ask (manual connec-tions).

Start battery
The vehicle's electrical system is single pole anduses the body and engine block as conductors.
The start (main) battery is used to power electri-cal components and systems. However, thehybrid battery is used to start the gasolineengine.
The start battery should only be replaced by atrained and qualified Volvo service technician.
The start battery is an Absorbed Glass Mat(AGM) 12-volt battery that is dimensioned foruse in vehicles to support electrical systems andfunctions.
The service life of a battery is affected by factorssuch as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

H8 AGM battery with strap
•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.

Hybrid battery
The vehicle's electric motor is powered by arechargeable, maintenance-free, lithium-ionhybrid battery.
The vehicle cannot be started if the hybridbattery is completely discharged.
WARNING
The vehicle's hybrid battery may only be serv-iced or replaced by a trained and qualifiedVolvo service technician.
Battery coolant
The hybrid battery's cooling system has its ownexpansion tank.
Filling the hybrid battery's cooling system shouldonly be done by a trained and qualified Volvoservice technician.

Replacing fuses
The fuses help protect the vehicle's electricalcomponents from overloading or short circuits.
Fuse replacement
1. See the list of fuse boxes for their locations.
2. Pull the fuse straight out and examine it fromthe side to see if the curved metal wire in thefuse is intact.
3. If the wire is broken, insert a new fuse of thesame color and amperage (written on thefuse).
WARNING
Never use metal objects or fuses with higheramperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.
