MAINTENANCE AND SERVICE

CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery and support battery. The rapidcharging function should not be used as thiscould damage the battery.
CAUTION
Failure to observe the following could cause the infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
• The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too many times, it will shorten its service life. The service life of the starter battery is affec- ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the 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 should beconnected to a battery charger with automatictrickle 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 func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that the ten-sioning strap is always securely tightened.

MAINTENANCE AND SERVICE
576
Support battery In addition to the start battery, vehicles equipped with the Start/Stop function also have a supportbattery.
Vehicles with the Start/Stop function are equip- ped with two 12-volt batteries ‒ a heavy-duty
start battery and a support battery that provides extra current during the Start/Stop function'sstart sequence.
The 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 has towork 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 driverdoes not lift their foot from the brake pedal.
The support battery does not normally requiremore service than the start battery. If you have any questions or concerns, consult a workshop ‒
an authorized Volvo workshop is recommended.
CAUTION
If the following is not observed, the Start/ Stop function may temporarily stop workingafter connection of an external starter batteryor battery charger: • The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.

Cleaning the leather upholstery
1. Apply the leather cleaner to a damp spongeand squeeze it until the cleaner foams.
2. Move the sponge in circular motions to apply the foam to the stain.
3. Dampen the stain thoroughly with the sponge. Let the sponge absorb the stain and do not rub.
4. Dry the stain using a soft towel and let the leather dry completely.
Protecting the leather upholstery
1. Apply a small amount of leather protector toa cloth and then apply the protector to the leather using light circular movements.
2. Let it dry for approximately 20 minutes. Protecting the leather upholstery makes it better able to withstand sunlight's harmful UV rays.
