brake VOLVO XC90 TWIN ENGINE 2018 Owners Manual

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.587
WARNINGIn a head-on collision at a speed of 50 km/h
(30 mph), an unsecured object weighing 20
kg (44 pounds) can reach a projectile weight
equivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper
edge of the side windows, leave a 10 cm (4
in.) space between the objects and the win-
dow. Objects placed closer to this could
impede the function of the inflatable curtain
concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift
during heavy braking and injure people in the
vehicle.
Cover sharp edges and sharp corners with
something soft.
Turn off the engine and apply the parking
brake when loading/unloading long objects.
Otherwise, it is possible for the load to reach
the gear lever or gear selector and move it to
a drive position – which could cause the vehi-
cle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to
increase cargo compartment space and simplify
loading. If the rear seat backrests are folded down, make sure that no objects loaded into the
vehicle prevent the WHIPS system for the front
seats from functioning correctly.
Raising/lowering the rear end of the
vehicle*
The rear end of the vehicle can be lowered or
raised for easier loading or to facilitate attaching
a trailer*.
The controls for raising/lowering are located at
the rear edge of the cargo compartment's right
side panel. Controls for raising/lowering the rear end of the vehicle.
The controls consist of two buttons ‒ one button
for lowering and one button for raising the rear
end. Press and hold the relevant button until the
desired height is reached.
The rear end of the vehicle cannot be raised
higher than its normal height. The rear end will return to the normal height
when the vehicle begins driving.
NOTE It is not possible to adjust the height of the
vehicle's rear when one or more of the doors
or the hood is open. This does not apply to
the tailgate.
WARNING
Make sure that no people, animals or objects
are found under the vehicle when it is low-
ered. This could endanger life and cause
damage to the vehicle or objects.

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.

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 technician
can connect your vehicle to the workshop's Wi-Fi
network to perform troubleshooting and down-
load software. For this type of communication,
the vehicle only connects to the workshop's net-
work. The vehicle can only be connected to the
designated workshop networks, not to any other
network, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by a
service technician. Because the technician uses
the buttons on your remote key to connect the
vehicle, it is important that you bring a key with
buttons when taking the vehicle in to a workshop.
Pressing the lock button on the remote key three
times will connect the vehicle to the workshop's
Wi-Fi network.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.

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.

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.

Only use cleaning agents and car care products
recommended by Volvo. Clean regularly and
treat stains immediately for best results. It is
important to vacuum before using a cleaning
agent.
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.

Automatic car washes
The vehicle should be washed as soon as it
becomes dirty. This makes the vehicle easier to
clean because dirt does not attach as strongly. It
also reduces the risk of scratches and keeps the
vehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to
keep your vehicle clean, but it does not reach all
areas of the vehicle. For best results, Volvo rec-
ommends hand washing your vehicle or supple-
menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in
an automatic car wash during the first few
months; the paintwork on new vehicles takes
some time to fully harden.
CAUTION
Before driving the vehicle into a car wash,
deactivate the Automatic Braking when Sta-
tionary and Automatic Parking Brake Applica-
tion functions. If the functions are not deacti-
vated, the brake system will seize when the
vehicle is stationary and the vehicle will not be
able to roll.
CAUTION For automatic car washes in which the vehicle
is pulled forward on rolling wheels:
1.

Before washing the vehicle, make sure
that the automatic rain sensor is deacti-
vated. If it is not deactivated and inadver-
tently starts, the wiper arms could be
damaged.
2. To help prevent damage from the auto- matic car wash machinery, make sure
that the door mirrors are folded in, anten-
nas retracted or removed, and any auxili-
ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in
the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-
play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.
Hold the knob in position for at least
2 seconds.
The vehicle is now ready for the automatic car
wash.
CAUTION The system will automatically change to P
mode if the above steps are not followed. In P
mode, the wheels are locked, which they
should not be when the vehicle is being
washed in a car wash.

CAUTION•
The maximum trailer weights listed are
only applicable for altitudes up to 3280 ft
(1,000 m) above sea level. With increas-
ing altitude the engine power and there-
fore the car's climbing ability are impaired
because of the reduced air density, so

reduced accordingly. The weight of the
car and trailer must be reduced by 10%
for every further 3280 ft (1,000 m) (or
part thereof).

The medium in the hydraulic brake system is
called brake fluid and is used to transfer braking
force from e.g. pressure on the brake pedal via a
master brake cylinder to one or more slave cylin-
ders, which in turn act on a mechanical brake.
Recommended grade: Volvo Original Dot 4
class 6 or equivalent.
NOTE
Changing or filling brake fluid should be
entrusted to an authorized Volvo workshop.
