IMPORTANT
Harmful if ingested. May cause organ
•
(kidney) damage.
Use ready-mixed coolant as recom-
•
mended by Volvo. If concentrated liq-
uid is used, make sure that the ratio is
50 % coolant to 50 % water of an
approved quality.
Do not mix different coolants.
•
Only new coolant should be used
•
when replacing major cooling system
components to ensure the system has
sufficient corrosion protection.
The engine must only be run with a
•
well-filled cooling system. Otherwise,
temperatures that are too high may
occur resulting in the risk of damage
(cracks) in the cylinder head.
A high content of chlorine, chlorides
•
and other salts may cause corrosion in
the cooling system.

Bulb replacement
This car is equipped only with LED
and therefore no replaceable bulbs. Contact a
workshop

if a fault occurs in the lighting.

If a fault occurs in LED
lamps, the entire
lamp unit usually must be replaced.
NOTE
For information about bulbs not covered in
this Owner's Manual, contact a Volvo
dealer or a certified Volvo service techni-
cian.
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.
