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 the engine compartment.
If the vehicle is instead equipped with a 48 V support battery, it is located under the cargo compartment.The box over the 48 V support battery may only beremoved by an authorized workshop.
WARNING
High voltage may be dangerous if handled incorrectly. Do not touch anything on bat-teries that is not clearly described in thisOwner's Manual. Never use a 48 V support battery to jump start the vehicle.
External electrical equipment may notunder any circumstance be connectedto the 48 V battery.
Only a workshop may replace or per-form service on the 48 V battery – anauthorized Volvo workshop is recom-mended.
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.

Hand washing
The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easierto clean because dirt does not attach asstrongly. It also reduces the risk of scratchesand keeps the vehicle looking new. Wash thevehicle in a car wash or garage with an oilseparator and use car washing detergent.Use cleaning agents and car care productsrecommended by Volvo.
Important to keep in mind when handwashing your vehicle
Avoid washing the vehicle in direct sun- light. This could cause the detergent orwax to dry out and become abrasive.
Remove bird droppings from paintwork assoon as possible. It contains chemicalsthat affect and discolor paintwork veryquickly. Use e.g. soft paper or a spongesoaked in lots of water. Consult an author-ized Volvo workshop for assistanceremoving discoloration.
Hose down the underbody, including thewheel housings and bumper.
Hose down the entire vehicle and removeany loose dirt, droppings etc. to reducethe risk of scratches from washing. Do notspray directly onto locks.
If necessary, use cold degreaser on heavilysoiled surfaces. Note that in such casesthe surfaces must not be hot from the sun.
Wash using a sponge, car washing deter-gent and plenty of lukewarm water. Makesure that the sponge is clean. A dirtysponge can scratch the paint.
Clean the wiper blades with lukewarmsoap solution or car washing detergent.
Dry the vehicle using a clean, soft chamoisor a squeegee. Try not to let drops ofwater dry in strong sunlight. This couldcause water drying stains that may needto be polished out.
In areas with heavy industrial emissions,more frequent washing of the vehicle'sexterior is recommended.
Tar spots from asphalt may remain evenafter washing. Use a Volvo-recommendedtar remover to remove these spots afterwashing the vehicle.
WARNING
Always entrust engine washing to a work- shop. If the engine is hot, there is a risk offire.
CAUTION
Dirty headlights do not work as well. Clean them regularly, e.g. when refueling. Do not use corrosive cleaners. Use water and a non-abrasive sponge.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
CAUTION
Make sure that the panoramic roof
*
and sun shade are closed before wash- ing the vehicle.
Never use abrasive polishing agents onthe panoramic roof.
Never use wax on the rubber sealsaround the panoramic roof.

Engine oil specifications Engine oil of type VCC RBS0-2AE 0W-20 must be used. Lower oil grades may not offerthe same fuel economy, engine performanceor engine protection.
Volvo recommends:
GeneralSee the Service and warranty booklet for infor- mation about oil change intervals.
NOTE
This vehicle is delivered from the factory with synthetic oil.
Do not use oil additives.
Oil viscosityThe wrong oil viscosity can shorten engine service life during normal use.VCC RBS0-2AE 0W-20 provides good fueleconomy and engine protection. See the vis-cosity chart.

Brake fluid specifications
The medium in the hydraulic brake system is called brake fluid and is used to transfer pres-sure from e.g. a brake pedal via a masterbrake cylinder, which in turn actuates thebrake calipers.
Recommended grade: Volvo Original or simi-
lar fluid that meets a combination of Dot 4, 5.1 and ISO 4925 class 6.
NOTE
Changing or filling brake fluid should be entrusted to an authorized Volvo work-shop.
