Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audiosystem.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Jump starting using another battery
If the start battery is discharged, current fromanother battery can be used to start the vehicle.
Jumper cable connecting points.
CAUTION
The charging point of the vehicle is onlyintended for jump starting the vehicle in ques-tion. The charging point is not intended forjump-starting another vehicle. Using thecharging point to start another vehicle couldcause a fuse to blow, which would cause thecharging point to stop working.
If a fuse has blown, 12 V Battery Fuse failureService required will be displayed in the instru-ment panel. Volvo recommends contacting anauthorized Volvo workshop.

To avoid short circuits or other damage, the fol-lowing steps are recommended when jump star-ting the battery:
1.Put the ignition in mode 0.
2.Make sure the auxiliary battery (the batteryused to jump start the discharged battery)has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle,turn off that vehicle's engine and make surethat the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliarybattery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to preventshort circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi-tive (+) jump start terminal (2).
6.Clamp the other end of the red jumper cableto your vehicle's positive (+) jump start termi-nal (2).
7. Clamp the black jumper cable onto the auxili-ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumpercable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securelyattached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle andlet it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the enginedoes not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normalconditions, the vehicle's electrical drive motoris prioritized – the gasoline engine remainsoff. This means that after the start knob hasbeen turned clockwise, the electric motor has"started" and the vehicle is ready to be driven.Start of the electric motor is indicated by theindicator lights on the instrument panel goingout and its preselected theme illuminating.
CAUTION
Do not touch the connections between thecable and the vehicle during the start attempt.Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then thered cables.
Make sure that none of the clamps of theblack jumper cables come into contact witheither vehicle's positive (+) jump start termi-nals or either of the red jumper cable's con-nected clamps.
WARNING
PROPOSITION 65 WARNING! Battery posts,terminals, and related accessories containlead and lead compounds, chemicals knownto the state of California to cause cancer andreproductive harm. Wash hands after han-dling.
WARNING
Batteries generate hydrogen gas, whichis 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.

STARTING AND DRIVING

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.
NOTE
The vehicle cannot be started if the hybridbattery is discharged.
NOTE
If the starter battery has been discharged tothe extent that the vehicle does not have nor-mal electrical functions and the engine mustthen be jump-started with an external batteryor a battery charger, the Start/Stop functionmay remain activated. If the Start/Stop func-tion shortly thereafter auto-stops the engine,there is a huge risk that auto-start of theengine will fail due to insufficient batterycapacity since the battery had not had time torecharge.
If the vehicle has been jump-started or ifthere has not been enough time for the bat-tery to be charged with a battery charger, theStart/Stop function should be temporarilydeactivated until the battery has beenrecharged by the vehicle. At an ambient tem-perature of about +15°C (about 60°F), thebattery must be charged by the vehicle for atleast one hour. At lower ambient tempera-tures, the charging time can increase to3-4 hours. It is advisable to charge the batterywith an external battery charger.

Driving with a trailer
There are a number of things to consider whentowing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi-cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly.

Towing using a towline
This section refers to one vehicle being towedbehind another using a towline.
Never attempt to tow a Twin Engine vehiclebehind another vehicle as this could damage theelectric motor. The vehicle must instead be liftedonto a tow truck and transported with all fourwheels on the bed or lifting platform of the truck(no wheels may touch the road).
Towing another vehicle
Towing another vehicle requires a lot of power -use the Constant AWD drive mode. This helpscharge the hybrid battery and improve the vehi-cle's driving and roadholding characteristics.
Before towing another vehicle, check applicablespeed limit regulations.
Jump starting
Never attempt to tow the vehicle to start theengine, as this could damage the electric motor.Use an auxiliary battery if the start battery'scharge level is so low that the engine cannot bestarted.
CAUTION
Attempts to tow-start the vehicle could causedamage to the electrical drive motor andthree-way catalytic converter.

Start battery
The vehicle has a single-pole electrical systemthat uses the chassis and engine mount as con-ductors.
The start battery is used to start the electricalsystem and power electrical equipment in thevehicle. The hybrid battery is used to start thecombustion engine.
The start battery should only be replaced by a
workshop17.
The start battery is a 12 V AGM (Absorbed GlassMat) 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, whichis flammable and explosive.
