Bulb replacement

Lamp types vary depending on model and
equipment level. If a bulb

breaks, it can be

Contact a workshop

if faults occur in lamps

other than bulbs.

If a fault occurs in LED

17

lamps, the entire

lamp unit usually must be replaced.

NOTE

WARNING

The car's electrical system must be in igni-

tion position

0

when replacing bulbs.

IMPORTANT

Never touch the glass part of the bulbs
with your fingers. Grease from your fingers
is vaporised by the heat, coating the reflec-
tor and then causing damage.

NOTE

If an error message remains after the bro-
ken bulb has been replaced then we rec-
ommend visiting an authorised Volvo
workshop.

NOTE

Outside lighting such as headlamps and
rear lamps may temporarily have conden-
sation on the inside of the lens. This is nor-
mal, all exterior lighting is designed to
withstand this. Condensation is normally
vented out of the lamp housing when the
lamp has been switched on for a time.

Cleaning the interior

Use cleaning agents and car care products
recommended by Volvo. Clean regularly, and
deal with stains straight away. Vacuuming is
important prior to using cleaning agents.

IMPORTANT

•

Certain items of coloured clothing (e.g.
dark jeans and suede garments) may
stain the upholstery. If this occurs, it is
important to clean and treat these
parts of the upholstery as soon as pos-
sible.

•

Never use strong solvents such as
washer fluid, pure petrol or white spirit
or concentrated alcohol to clean the
interior, since this may damage the
upholstery as well as other interior
materials.

•

Never spray the cleaning agent directly
onto components that have electrical
buttons and controls. Wipe them
instead using a moistened cloth con-
taining the cleaning agent.

•

Sharp objects and Velcro may damage
the fabric upholstery.

•

Only use cleaning agents on the type
of material for which they were
intended.

An authorised Volvo workshop is recommended.

Cleaning the centre display

Dirt, stains and grease from fingers can affect
the centre display's performance and reada-
bility. Clean the screen frequently with a
microfibre cloth.

1. Turn off the centre display with a long

press on the home button.

2. Wipe the screen with the microfibre cloth

supplied or use another microfibre cloth of
equivalent quality. Wipe the screen with a
clean and dry microfibre cloth using small
circular movements. If necessary, lightly
moisten the microfibre cloth with clean
water.

3. Activate the display with a short press on

the home button.

IMPORTANT

The microfibre cloth used to clean the cen-
tre display must be free from sand and dirt.

IMPORTANT

When cleaning the centre display, only use
gentle pressure on the screen. Heavy pres-
sure can damage the screen.

IMPORTANT

Do not spray any liquid or caustic chemi-
cals directly on the centre display. Do not
use window cleaning agent, other cleaning
agents, aerosol spray, solvents, alcohol,
ammonia or cleaning agent containing
abrasive.

Never use abrasive cloths, paper towels or
tissue paper, since they may scratch the
centre display.
