Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:
Current (V)12
Cold start capacity (Cold Cranking 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 support battery 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 brake pedal is depressed.
The support battery does not normally required more 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 or a 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 battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and 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 battery should 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 to disable the Start/Stop function until the bat-tery is sufficiently recharged.

Fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the lists offuses. Doing so could seriously damage oroverload the vehicle's electrical system.
If an electrical component fails to function, this may 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.

Fuse replacement1. See the list of fuse boxes for their locations.
2. Pull the fuse straight out and examine it from
the side to see if the curved metal wire in the fuse is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on thefuse).
WARNING
Never use metal objects or fuses with higher amperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.

Replacing bulbs
The halogen headlight bulbs can be replaced by the owner.
Before the bulbs can be replaced, that plastic covering over the headlight housing has to beremoved.
To do so:
Lift the rubber strip by pressing in toward the engine compartment.
Release the pins in the plastic covering's four clips by pressing them down with ascrewdriver or similar object and remove thecovering.
The turn signal, high/low beam, Daytime RunningLight and parking light bulbs will be accessiblewhen the plastic covering has been removed. Put the covering back in place in the reverse order.
NOTE
The pins in the clips have to be pressed back completely before the clips are placed in theplastic covering. When the covering is put back in place, the pins must be pressed so that their upper sur-face is flush with the surface of the clip.
NOTE
• For information regarding any bulbs not mentioned in this section, please contactyour Volvo retailer or a trained andauthorized Volvo service technician.
• Always switch off the ignition before star-ting to replace a bulb.
• If an error message remains in the dis-play after a faulty bulb has been replaced,contact an authorized Volvo workshop.
• Condensation may form temporarily onthe inside of the lenses of exterior lightssuch as headlights, fog lights, or taillights.This is normal and the lights aredesigned to withstand moisture. Normally,condensation will dissipate after thelights have been on for a short time.
• The optional Active Bending Light bulbscontain trace amounts of mercury. Thesebulbs should always be disposed of by atrained and qualified Volvo service techni-cian.
CAUTION
Never touch the glass of bulbs with your fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which will damage it.
