Jump starting using another battery
If the start battery is discharged, current from
another battery can be used to start the vehicle. Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only
intended for jump starting the vehicle in ques-
tion. The charging point is not intended for
jump-starting another vehicle. Using the
charging point to start another vehicle could
cause a fuse to blow, which would cause the
charging point to stop working.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instru-
ment panel. Volvo recommends contacting an
authorized 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 battery
used 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 sure
that the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION Connect the jump cable carefully to prevent
short circuits with other components in the
engine 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 cable
to 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 jumper cable to your vehicle's negative (-) ground
point (4). 9. Make sure the jumper cables are securely
attached to help prevent sparks while jump
starting.
10. 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.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10
minutes of charging time and then try to start
the engine again.
NOTE When the engine is started under normal
conditions, the vehicle's electrical drive motor
is prioritized – the gasoline engine remains
off. This means that the electric motor has
"started" and the vehicle is ready to be driven
once the start knob has been turned clock-
wise. Start of the electric motor is indicated
by the indicator lights on the instrument panel
going out and its preselected theme illuminat-
ing.
CAUTION
Do not touch the connections between the
cable and the vehicle during the start attempt.
Risk of sparking.

||STARTING AND DRIVING
* Option/accessory.
482 12. 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
either 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 contain
lead and lead compounds, chemicals known
to the state of California to cause cancer and
reproductive harm. Wash hands after han-
dling.
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.
NOTE The vehicle cannot be started if the hybrid
battery is discharged.

Driving with a trailer (p. 483) Towing using a towline
This 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 the
electric motor. The vehicle must be lifted onto a
tow truck and transported with all four wheels on
the bed or lifting platform of the truck (no wheels
may touch the road).
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 an
auxiliary battery if the start battery's charge level
is so low that the engine cannot be started.
CAUTION Attempts to tow-start the vehicle could cause
damage to the electrical drive motor and
three-way catalytic converter.

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 the
vehicle. The hybrid battery is used to start the
combustion 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's
various 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 the
engine is running.
Make sure the cables to the start battery are
correctly connected and the clamps are
securely tightened.
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.

after handling.Use the vehicle's connection points in the engine
compartment to connect an external start battery
or battery charger.
The battery terminals on the car's start battery in
the luggage/cargo area must not be used.

CAUTION
It is not possible to charge another vehicle's
battery by means of current through the
charging points. Using the charging points to
charge another vehicle's battery could cause
a fuse to blow, which would cause the charg-
ing points to stop working.
