||MAINTENANCE AND SERVICE

Monthly:

Check cold tire pressure in all tires. Inspect
the tires for wear.
Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
Clean interior glass surfaces with a glass
cleaner and soft paper towels.
Wipe driver information displays with a soft
cloth.
Visually inspect battery terminals for corro-
sion. Corrosion may indicate a loose terminal
connector, or a battery near the end of its
useful service life. Consult your Volvo retailer
for additional information.
As needed:
Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup of
dirt, and corrosion that can be caused by salt res-
idues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other places
where they may collect.

technicians is available online for purchase or

Engine compartment overview (p. 622) Data transfer between vehicle and
workshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-
work for secure data transfer between your vehi-
cle and the workshop. Your visit to the workshop
will be easier and more effective when diagnos-
tics information and software can be transferred
over the workshop's network.
When you arrive at the workshop, your service
technician can connect your vehicle to the work-
shop's Wi-Fi network to perform troubleshooting
and download software. For this type of commu-
nication, the vehicle only connects to a work-
shop's network. It is not possible to connect the
vehicle to another Wi-Fi network (e.g. your home
network) in the same way as to a workshop's net-
work.
Connecting with remote keyConnection is usually managed by the service
technician, who will use the remote key buttons. It
is therefore important to bring a key with buttons
with you when you visit the workshop. Pressing
the lock button on the remote key three times will
connect the vehicle to the workshop's Wi-Fi net-
work.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.

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.
