Towing using a towlineThis section refers to one vehicle being towed behind another using a towline.
Twin Engine vehicles may not be towed behind another vehicle due to the risk of damage to theelectric motor. If the vehicle cannot be driven andneeds to be moved, it must be transported on atow truck with all four wheels on the bed of thetruck.
Towing another vehicleTowing another vehicle requires a lot of power - use the AWD drive mode. This helps charge the
hybrid battery and improve the vehicle's driving and roadholding characteristics. Before towing another vehicle, check applicable speed limit regulations.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motor andthree-way catalytic converter.

Using the electrical outlets
The 12 V outlet can be used for devices intended for this such as MP3 players, coolersand cellular phones. The high-voltage outlet * can be used for devices
intended for this, such as chargers, laptops, etc.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be active as long as there is sufficient charge in thestart battery. If the engine is turned off and the vehicle is locked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for up to7 minutes.
NOTE
Bear in mind that using the electrical outlets when the engine is off could cause the starterbattery to have too low of a charge level,which could limit other functionality. Accessories connected to the electrical out- lets can be activated even when the vehicleelectrical system is off or if preconditioning isused. For this reason, disconnect plugs whenthey are not in use to prevent the starter bat-tery from becoming discharged.
WARNING
• Do not use accessories with large or heavy plugs – they could damage the out-let or come loose while you are driving.
• Do not use accessories that could causedisruptions to e.g. the vehicle's radioreceiver or electrical system.
• Position the accessory so that there is norisk of it injuring the driver or passengersin the event of heavy braking or a colli-sion.
• Pay attention to connected accessoriesas they can generate heat that could burnpassengers or the interior.
Using 12 V outlets1. Remove the stopper (tunnel console) or fold
down the cover (trunk/cargo compartment)over the socket and plug in the device.
2. Unplug the device and put the stopper back in (tunnel console) or fold up the cover(trunk/cargo compartment) when the socketis not in use or left unattended.
CAUTION
The maximum power is 120 W (10 A) per outlet.
Using high-voltage outletsThe ignition must be in at least mode I for outlets
to supply current. The outlets will then be active as long as there is sufficient charge in the startbattery. 1. Slide down the cover over the outlet and plug in the device. >
The LED 2
light on the outlet will indicate
its status.
2. The outlet is supplying electrical current when the light is glowing steadily green.
3. Disconnect the device by pulling out the plug (do not pull on the cord). Pull up the cover when the outlet is not in use or is left unattended.
CAUTION
The maximum power is 150 W.
WARNING
Do not attempt to alter or repair the high-volt- age outlet on your own. Volvo recommendscontacting an authorized Volvo workshop.

Start battery
The vehicle has a single-pole electrical system that uses the chassis and engine mount as con-ductors. 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 15
.
The start battery is a 12 V AGM (Absorbed Glass Mat) battery, dimensioned for regenerative charg-ing and to support the function of the vehicle'svarious systems. The service life and performance of the start bat- tery are affected by factors such as driving style,driving conditions, climate, battery discharges,number of starts, etc.
• Never disconnect the start battery while theengine is running.
• Make sure the cables to the start battery arecorrectly connected and the clamps aresecurely tightened.
WARNING
•Batteries generate hydrogen gas, which is flammable and explosive.
• Do not connect the jumper cable to anypart of the fuel system or to any movingparts. Avoid touching hot manifolds.
• Battery fluid contains sulfuric acid. Do notallow battery fluid to contact eyes, skin,fabrics or painted surfaces.
• If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
• Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.
Connection points
WARNING
PROPOSITION 65 WARNING Battery posts, terminals, and related accesso- ries contain lead and lead compounds, chemi-cals known to the state of California to causecancer and reproductive harm. Wash handsafter handling. Use the vehicle's connection points in the engine compartment to connect an external start batteryor battery charger. The battery terminals on the car's starter battery in the luggage/cargo area must
not be used.
Positive connection point

MAINTENANCE AND SERVICE
616
CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery. The rapid charging functionshould not be used as this could damage thebattery.
NOTE
If both the starter battery and the hybrid bat- tery are discharged, both batteries must be
charged. In such cases, it is not possible to charge only the hybrid battery first. The starter battery must have a certain level of charge for it to be possible to charge thehybrid 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.

Hybrid battery
The vehicle's electric motor is powered by a rechargeable, maintenance-free, lithium-ionhybrid battery.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
NOTE
If both the starter battery and the hybrid bat- tery are discharged, both batteries must be
charged. In such cases, it is not possible to charge only the hybrid battery first. The starter battery must have a certain level of charge for it to be possible to charge thehybrid battery.
WARNING
Hybrid battery replacement may only be per- formed by a workshop – an authorized Volvoworkshop 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 – an authorizedVolvo workshop is recommended.
SpecificationsType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases with age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.
