The rectangular section of the clip points toward the front and rear of the vehicle.
5. To remove a clip: Insert a flat object (e.g.kitchen knifes or screwdrivers) into both short sides of the clip to release both
catches at the same time and then pry
and pull out the clip.
The hinge's plastic cover is held into place by a plas- tic clip and three latches.
6. To remove the hinge's plastic cover on the side in which the fog light is mounted: Press down the pin in the center of theplastic clip using a screwdriver or similar.Pry/pull out the plastic clip.
7. Release the plastic cover's three latches using e.g. a small screwdriver and removethe plastic cover. 8. Carefully pry and pull down the loosened
section of panel to access the bulb.
NOTE
To bear in mind when reinstalling the plas- tic rivet for the plastic guard of the hinge:
Before the plastic rivet can be used forreinstallation, its center pin must first bepressed back far enough that it pro-trudes from the plastic rivet.
Once the plastic guard of the hinge issecured in position, press the plasticrivet into the hole of the plastic guard.
Finally, the pin is pressed into the plas-tic rivet until its end surface is in linewith the surface of the plastic rivet.

Start battery
The vehicle has a single-pole electrical sys- tem that uses the chassis and engine mountas conductors. The start battery is used to start the electrical system and power the starter motor andother electrical equipment in the vehicle. The start battery should only be replaced by a workshop 22
.
The vehicle has a voltage-regulated alternating current generator. The start battery is a 12 V battery, dimen- sioned for the carbon dioxide-reducing func-tions Start/Stop and regenerative chargingand to support the function of the vehicle'svarious systems. The service life and performance of the start battery are affected by factors such as drivingstyle, driving conditions, climate, battery dis-charges, number of starts, etc. Never disconnect the start battery while the engine is running.
Make sure the cables to the start batteryare correctly connected and the clampsare securely tightened.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.

WARNING
California Proposition 65 Operating, servicing and maintaining a pas- senger vehicle can expose you to chemi-cals including engine exhaust, carbon mon-oxide, phthalates, and lead, which areknown to the State of California to causecancer and birth defects or other reproduc-tive harm. To minimize exposure, avoidbreathing exhaust, do not idle the engineexcept as necessary, service your vehicle ina well ventilated area and wear gloves orwash your hands frequently when servicingyour vehicle. For more information go towww.P65Warnings.ca.gov/passenger-vehicle.
Use the vehicle's connection points in the engine compartment to connect an externalstart battery or battery charger. The battery terminals on the car's start battery in the luggage/cargo area must not be used.
If the start battery is being charged, the sup-port battery will also be charged.

Positive connection point
Negative connection point
CAUTION
Only a modern battery charger with con- trolled charge voltage should be used tocharge the starter battery and support bat-tery. The rapid charging function shouldnot be used as this could damage the bat-tery.
CAUTION
Failure to observe the following could cause the infotainment energy save modeto temporarily stop working and/or a mes-sage in the driver's display regarding thestate of charge of the starter battery maybe temporarily incorrect after an externalstarter battery or battery charger has beenconnected:
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 becomes discharged too many times, it will shorten its servicelife. The service life of the starter battery is affected by several factors, such as drivingconditions and climate. The startingcapacity of the battery reduces graduallyover time. The battery must therefore berecharged if the vehicle is not used or along period of time or if it is only drivenshort distances. Severe cold further limitsthe starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery shouldbe connected to a battery charger withautomatic trickle charging. A starter battery that is always kept fully charged has the maximum service life.

Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the function for automatic opening and closingmust be reset to function correctly. A resetis required in order for the pinch protectionto work.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that thetensioning strap is always securely tight-ened.

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.
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.
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.
