NOTE
If the conditions for measuring oil level arenot properly fulfilled (time after engine shut-down, vehicle inclination, ambient tempera-ture, etc.) the message No value availablewill be shown in the center display. This doesnot mean that anything is wrong in the vehi-cle systems.

Refilling coolant
Coolant helps keep the combustion engine atthe right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions onthe package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant.
If there is coolant under the vehicle, smoke fromthe cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.

WARNING
The coolant may be very hot. Never unscrewthe cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

MAINTENANCE AND SERVICE
572
Open the cap in the plastic covering.
Unscrew the expansion tank cap and fillcoolant as needed. The level should notexceed the yellow MAX mark inside theexpansion tank.
Put the components back in place in the reverseorder.

CAUTION
Do not ingest the contents. May causedamage to organs (kidneys).
Use premixed coolant according to Vol-vo's recommendations. If concentratedcoolant 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 inthe cooling system.
Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
Bulb types vary depending on model and equip-
ment level. If a light bulb14 breaks, it can bereplaced by following the procedure shown inthe Owner's Manual.
If you are experiencing problems with any lights
other than light bulbs, contact a workshop15.
If there is a problem with an LED16 light, theentire lamp unit will normally need to bereplaced.
NOTE
For information on lights not mentioned in theOwner's Manual, contact a Volvo dealer or acertified Volvo service technician.

NOTE
Exterior lighting such as headlights and tail-lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
14Some vehicles do not have any light bulbs.15An authorized Volvo workshop is recommended.16LED (Light Emitting Diode)

MAINTENANCE AND SERVICE

Hybrid battery
The vehicle's electric motor is powered by arechargeable, maintenance-free, lithium-ionhybrid battery.

NOTE
The vehicle cannot be started if the hybridbattery is discharged.

NOTE
If both the starter battery and the hybrid bat-tery are discharged, both batteries must becharged. In such cases, it is not possible tocharge only the hybrid battery first.
The starter battery must have a certain levelof charge for it to be possible to charge thehybrid battery.

WARNING
Hybrid battery replacement may only be per-formed by a workshop – an authorized Volvoworkshop is recommended.

Coolant
The hybrid battery's cooling system has its ownexpansion tank.
CAUTION
Filling the hybrid battery coolant should onlybe performed by a workshop – an authorizedVolvo workshop is recommended.

Specifications for hybrid battery
Type: Lithium-ion
Power reserve: 10.4 kWh.

NOTE
The capacity of the hybrid battery decreaseswith age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.
