Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

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 electrical equipment in thevehicle. The hybrid battery is used to start thecombustion engine. The start battery should only be replaced by a workshop 17
.
The start battery is a 12 V AGM (Absorbed Glass Mat) battery, dimensioned for regenera-tive charging and to support the function ofthe vehicle's various 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.

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.

NOTE
If both the starter battery and the hybrid battery are discharged, both batteries
must be charged. In such cases, it is notpossible to charge only the hybrid batteryfirst. The starter battery must have a certain level of charge for it to be possible tocharge the hybrid battery.
WARNING
Hybrid battery replacement may only be performed by a workshop – an authorizedVolvo workshop is recommended.
CoolantThe hybrid battery's cooling system has its own expansion tank.
CAUTION
Filling the hybrid battery coolant should only be performed by a workshop – anauthorized Volvo workshop is recom-mended.
