||MAINTENANCE AND SERVICE
* Option/accessory.
626 Lift the rubber strip by pressing it inward into
the engine compartment.
Remove the plastic cover by folding out the
catch and lifting the cover upward.
Unscrew the expansion tank cap and fill
coolant as needed. The level should be
between the MIN and MAX marks on the
expansion tank.
CAUTION
Do not ingest the contents. May cause
damage to organs (kidneys).
Use premixed coolant according to Vol-
vo's recommendations. If concentrated
coolant is used, make sure that the cool-
ant mixture is 50% coolant and 50%
water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-
tection in the system, only use new cool-
ant when replacing larger components in
the cooling system.
Never run the engine unless the cooling
system is properly filled. An improperly
filled cooling system could lead to high
temperatures and cracks in the cylinder
heads.
High levels of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.

bulbs must be replaced by a workshop.
An authorized Volvo workshop is recommended.
NOTE For information on lights not mentioned in
this article, contact a Volvo dealer or a certi-
fied Volvo service technician.
NOTE
Exterior lighting such as headlights and tail-
lights may develop temporary condensation
on the inside of the lens. This is normal. All
exterior lighting is designed to resist this.
Condensation is normally vented out of the
lamp housing once the light has been lit for
some period of time.
NOTE
Bulbs for active curve lighting* contain traces
of mercury and should therefore always be
submitted to a certified Volvo service techni-
cian. 14

MAINTENANCE AND SERVICE
631
Hybrid battery
The vehicle's electric motor is powered by a
rechargeable, maintenance-free, lithium-ion
hybrid battery.
NOTE The vehicle cannot be started if the hybrid
battery is discharged.
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.
WARNING
Hybrid battery replacement may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.
CoolantThe hybrid battery's cooling system has its own
expansion tank.
CAUTION Filling the hybrid battery coolant should only
be performed by a workshop – an authorized
Volvo workshop is recommended.
Specifications for hybrid batteryType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases
with age and use, which could result in
increased use of the combustion engine,
leading to higher fuel consumption and
reduced electric motor range.
