LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.
606 Installing and removing the cargo
net*
The cargo net helps prevent objects in the cargo
compartment from entering the passenger com-
partment in the event of a sudden stop or hard
braking.
The cargo net is attached at four points. For safety reasons, the cargo net must always be
mounted and secured according to the following
description.
The net is made of strong nylon weave and can
be attached in two different locations in the vehi-
cle:
Rear mounting - behind the second row of
seats.
Front mounting - behind the front seats.
WARNING Objects in the cargo compartment must
always be securely anchored, even with a cor-
rectly installed cargo net.
Installing the cargo net
WARNING
All of the cargo net's upper consoles, hooks
and straps must be securely mounted and
attached before the net is used.
Never use the net if it is damaged.
NOTE
With front mounting, the cargo net is most
easily installed via a rear door.
1. Fold out the cargo net and make sure that
the upper rod folds out and locks into posi-
tion.
2.

Insert one of the net's hooks into the front or
rear ceiling mounting point with the strap
lock facing you. 3. Insert the net's other upper hook into the
ceiling mounting point on the opposite side.
The telescopic spring-loaded hooks make
mounting easier.
Make sure that the net's hooks are pushed
forward as far as possible into their respec-
tive mounting points.

||MAINTENANCE AND SERVICE
612
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.
NOTE Complete service information for qualified
technicians is available online for purchase or

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.

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.

WARNING
Never use more than one inlay mat at a
time on the driver's floor. If any other type
of floor mat is used, remove the original
mat from the driver's seat floor before
driving. All types of mats must be securely
anchored in the attachment points in the
floor. Make sure the floor mat does not
impede the movement of the brake pedal
or accelerator pedal in any way, as this
could be a serious safety hazard.
Volvo's floor mats are specially manufac-
tured for your vehicle. They must be prop-
erly secured in the attachment points in
the floor to help ensure they cannot slide
and become trapped under the pedals.
After vacuuming, a specially designed textile
cleaning agent should be used to remove stains
on floor mats. Floor mats should be cleaned with
products recommended by Volvo retailers.

Leather upholstery*Volvo's leather upholstery is treated to protect its
original appearance. Over time, sunlight, grease,
dirt, etc. could break down the protective layer.
This could result in scratches and cracking.
Leather upholstery is a natural product that
changes and acquires a beautiful patina over
time. Regular cleaning and treatments are
required to preserve the qualities and color of the
leather. Volvo offers a comprehensive product,
Volvo Leather Care Kit/Wipes, for cleaning and
treating leather upholstery that, when used as
directed, preserves the leather's protective coa-
ting.
For best results, Volvo recommends cleaning and
applying protective cream one to four times a
year (or more as needed). Volvo Leather Care Kit
951 0251 and Volvo Leather Softener 943
7429 are available for purchase at Volvo retailers.
