Wi-Fi connection to a workshop The time a vehicle is in a workshop for service or repairs can be reduced by transmitting trouble-shooting information as soon as the car reachesthe workshop. This is done most conveniently by selecting
Automatically connect when I arrive in the
center display's Settings menu.
Each time the vehicle slows down to a sufficiently low speed, it begins searching for a Wi-Fi net-work. If an authorized Volvo network (at a retaileror workshop) is found, a message will be dis-played or a pop-up window will open in the cen-ter display (this applies to manual connections,see the section "Manually connecting to a work-shop" below).
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 engine is 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 driver does not tap the
Cancel button in the message. To help prevent the driver from being disturbed by 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 a connection. If the vehicle stops at a workshop and the engine is 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 in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt 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 workshopManual connections are handled by the service technician.
Changing the way a connection is madeThe type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view and
tap

2. Tap

tions).

Start battery
The vehicle's electrical system is single pole and uses 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 a trained 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 factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

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. Orange wires may only be handled by trained and authorized Volvo service technicians orlicensed electricians. A number of component in the vehicle used high voltage electrical current and can be verydangerous to touch. Do not touch any components that are not clearly described in this owner's information.
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).

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.

Engine compartment overview
The engine compartment overview shows some maintenance points.
Some of the components in the vehicle's electri- cal drive system are located in the engine com-partment.
WARNING
• Orange cables should only be handled by a trained and qualified Volvo service tech-nician.
• A number of the vehicle's componentsuse high voltage and can be very danger-ous if handled improperly.
• Do not touch any components that havenot been clearly described/explained inthis manual.
• Use caution when checking/refilling flu-ids in the engine compartment.
• The cooling fan (located at the front ofthe engine compartment, behind the radi-ator) may start or continue to operate (forup to 6 minutes) after the engine hasbeen switched off.
• Engine cleaning should only be done by aworkshop. If engine cleaning agents areused when the engine has been running,there may a fire risk.
• Before performing any operations in theengine compartment, the ignition shouldalways be completely switched off (in mode
0) and there should be no remote
keys in the passenger compartment. Thegear selector should be in the P (park)
position. If the engine has been running, wait until it has cooled before touchingany components in the engine compart-ment.
