If the vehicle's start battery(12 V) is discharged, current from another battery can be used to start the vehicle's electrical system.
If the 12 V battery (start battery) is discharged, the vehicle's electrical system can be jump-started from another vehicle's battery using jumper cables. If the hybrid battery is also discharged, it must be charged using the charging cable after the electrical system is started so that the engine can be started.
Jumper cable charging points. There are two connecting points under the cover. Only use the one closest to the passenger compartment.
Important
The charging points of the vehicle are only intended for jump-starting the vehicle in question. Do not use them to start other vehicles – the charging circuit's fuse could be overloaded and stop working.
If a fuse has become overloaded, 12 V Battery Fuse failure Service required will be displayed in the instrument panel. Volvo recommends contacting an authorized Volvo workshop.
To avoid short circuits or other damage, the following steps are recommended when jump starting the battery:
Put the ignition in mode 0.
Make sure that the assisting battery has a voltage of 12 V.
If the battery is in another vehicle, turn off that vehicle's engine and make sure that the vehicles are not touching each other.
Clamp one end of the red jumper cable to the assisting battery's positive terminal (1).
Important
Connect the jumper cable carefully to prevent short circuit and contact with other components in the engine compartment.
Fold back the cover over your vehicle's positive charging point (2).
There are two connecting points under the cover. Only use the connecting point closest to the passenger compartment.
Clamp the other end of the red jumper cable to your vehicle's positive charging point (2).
Clamp one end of the black jumper cable to the assisting battery's negative terminal (3).
Clamp the other end of the black jumper cable to your vehicle's negative charging point (4).
Make sure the jumper cables are securely attached to help prevent sparks while jump starting.
Start the engine of the assisting vehicle and let it run for a few minutes at a higher idling speed than normal, about 1500 rpm.
To activate the vehicle's electrical system, press and hold the start button for at least 5 seconds without pressing the brake.
Note
Under normal conditions, only the vehicle's electric motor is used at startup. The combustion engine only starts when it is needed while driving. To indicate that the vehicle has started, the instrument panel will illuminate and its indicator lights will go out.
Important
Do not touch the connections between the cable and the vehicle during the start attempt. Risk of sparking.
Wait at least two minutes to charge the start battery and then try to start the engine again.
If the engine still doesn't start, repeat steps 11 and 12.
Note
The vehicle cannot be started if the hybrid battery is discharged.
Remove the jumper cables in the reverse order ‒ first the black cables and then the red cables.
Make sure that none of the clamps of the black jumper cables come into contact with the vehicle's positive charging point, the assisting vehicle's battery's positive terminal, or either of the red jumper cable's connected clamps.
Warning
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot manifolds.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces.
If contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Never expose the battery to open flame or electric spark. Do not smoke near the battery. Failure to follow the instructions for jump starting can lead to injury.
Warning
PROPOSITION 65 WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling.
