CAUTION
Snow chains can be used on the vehicle, with
the following restrictions:
• Volvo recommends not using snow
chains on wheel dimensions larger than
19 inches.
• Always follow the manufacturer's installa-
tion instructions carefully. Install chains
as tightly as possible and retighten peri-
odically.
• Only put snow chains on the front wheels
(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"
tires and wheels with different dimen-
sions than the original tires and wheels
are used, snow chains in some cases
may NOT be used. Sufficient distance
between the chains and brakes, suspen-
sion and body components must be
maintained.
• Check local regulations regarding the use
of snow chains before installing.
• Never exceed the snow chain manufac-
turer's specified maximum speed limit.
Under no circumstances should you
exceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns when
driving with snow chains. •
Avoid driving on surfaces without snow as
this wears out both the snow chains and
the tires.
• The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
• Some types of strap-on chains affect
brake components and therefore must
NOT be used. Consult a Volvo retailer for more information
about snow chains.

Winter driving (p. 461) Tire sealing system
13
The temporary tire sealing system can be used
to seal a puncture in a tire or to check and
adjust the pressure in the tire.
Models equipped with a spare wheel 14
do not
have the tire sealing system.
The tire sealing system consists of a compressor
and a bottle containing sealing compound. The
sealing functions as a temporary repair.
NOTE The sealing compound effectively seals tires
with punctures in the tread but may not be
able to fully seal tires with punctures in the
sidewall. Do not use the tire sealing system
on tires with large tears, cracks or similar
damage.
NOTE
The compressor is intended for temporary tire
sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block
under the floor of the cargo compartment.

584 Using the electrical outlets
The 12 V outlet can be used for devices
intended for this such as MP3 players, coolers
and 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 the
start battery.
If the engine is turned off and the vehicle is
locked, the outlets will be deactivated. If the
engine is turned off and the vehicle remains
unlocked, the sockets will remain active for up to
7 minutes.
NOTE Bear in mind that using the electrical outlets
when the engine is off could cause the starter
battery 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 vehicle
electrical system is off or if preconditioning is
used. For this reason, disconnect plugs when
they 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 cause
disruptions to e.g. the vehicle's radio
receiver or electrical system.
• Position the accessory so that there is no
risk of it injuring the driver or passengers
in the event of heavy braking or a colli-
sion.
• Pay attention to connected accessories
as they can generate heat that could burn
passengers or the interior.

Hoisting the vehicle
When hoisting the vehicle, it is important to
ensure the jack/vehicle hoist is correctly
engaged in the designated attachment points
under the vehicle.
For vehicles with self-leveling*, pneumatic sus-
pension (if installed) must be turned off before
the vehicle is lifted. Turning off the function in the
center display.
WARNING If the vehicle is lifted on a garage jack, the
jack must be placed under one of the four lift-
ing points. Make sure that the vehicle is cor-
rectly positioned on the jack and that it can-
not slide off. Make sure the jack plate has a
rubber pad to help keep the vehicle stable
and prevent damage. Always use axle stands
or similar.
NOTE Volvo recommends only using the jack
intended for your specific vehicle model. If a
jack other than that recommended by Volvo is
used, follow the instructions included with the
equipment.
The vehicle's ordinary jack is only intended to
be used in temporary situations for short peri-
ods of time, such as when changing wheels in
the event of a flat tire. If the vehicle needs to
be lifted more frequently, or for a longer
period of time than for a wheel change, a
garage jack or hoist is recommended. Always
follow the instructions for use provided with
the equipment.

Engine compartment overview
This overview shows some service-related com-
ponents. Some of the components included in the vehi-
cle's electric drive system are located in the
engine compartment. Exercise caution when
accessing the engine compartment and only
touch what is required for normal maintenance.
WARNING Orange wiring may only be handled by quali-
fied personnel.
WARNING
Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure.
• Do not touch anything that is not clearly
described in this Owner's Manual.
• Be careful when checking/filling fluids in
the engine compartment. The layout of the engine compartment may vary depend-
ing on model and engine variant.

||MAINTENANCE AND SERVICE

CAUTION
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery. The rapid charging function
should not be used as this could damage the
battery.
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 the
hybrid battery.
CAUTION Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery 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 or
battery 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 the
battery 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 it
is 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 least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging.
A starter battery that is always kept fully
charged has the maximum service life.
