It may be necessary to top up engine oil between regularly scheduled services. No action is necessary with regard to engine oil level until a message appears in the instrumentpanel.
WARNING
If this symbol is shown together with the message Engine oil level
Service required, visit a workshop
– an authorized Volvo workshop is
recommended. The oil level may be too high.
CAUTION
If this symbol is shown together with a message about low oil level, for example
Engine oil level low
Refill 1 liter, fill only with the indi-
cated volume, e.g. 1 liter (1 quart).
WARNING
Do not spill oil on the hot exhaust pipes as this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the electronic oil level gauge in the center display once thevehicle has been started. The oil level should bechecked regularly.
1. Open the Car status app from App view in
the center display.
2. Tap
Status to display the oil level.
Oil level graphic in the center display.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The vehiclemust have been driven approximately 30 km(20 miles) and have been stationary5 minutes on a level surface and with theengine off before the correct oil level will bedisplayed.

Refilling coolant
Coolant helps keep the combustion engine at the 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 on the 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 from the 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 unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

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
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• 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
The bulbs in the halogen headlights can be changed without the help of a workshop. Halogen headlights are not available on all mod- els and markets. Contact a Volvo retailer formore information. LED 13
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.
The headlight bulbs can be replaced without the assistance of a workshop, but before a bulb canbe replaced, the plastic cover over the headlightneeds to be removed. The low beam lights will be accessible when the headlight's round rubber cover has beenremoved. The bulbs of the turn signals, high beam and day- time running lights/parking lights are accessibleonce the rectangular headlight cover has beenremoved.

. If
there is a problem with an LED 13
light, the entire
lamp unit will normally need to be replaced.
WARNING
The vehicle electrical system must be in igni- tion mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fin- gers. Grease and oils from your fingers vapor-ize in the heat and will leave a deposit on thereflector, which may damage it.
NOTE
If the error message persists after the defec- tive bulb has been replaced, we recommend avisit to an authorized Volvo workshop.
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.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.

Start battery
The vehicle has a single-pole electrical system that uses the chassis and engine mount as con-ductors. The start battery is used to start the electrical system and power the starter motor and otherelectrical equipment in the vehicle. The start battery should only be replaced by a workshop 18
.
The vehicle has a voltage-regulated alternating current generator. The starter battery is a 12 V battery, designed for the carbon dioxide reducing functions Start/Stopand regenerative charging, and to support thefunctionality of the car's different systems. The service life and performance of the start bat- tery are affected by factors such as driving style,driving conditions, climate, battery discharges,number of starts, etc.
• Never disconnect the start battery while theengine is running.
• Make sure the cables to the start battery arecorrectly connected and the clamps aresecurely tightened.
WARNING
•Batteries generate hydrogen gas, which is flammable and explosive.
• Do not connect the jumper cable to anypart of the fuel system or to any movingparts. Avoid touching hot manifolds.
• Battery fluid contains sulfuric acid. Do notallow battery fluid to contact eyes, skin,fabrics or painted surfaces.
• If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
• Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.
Connection points
WARNING
PROPOSITION 65 WARNING Battery posts, terminals, and related accesso- ries contain lead and lead compounds, chemi-cals known to the state of California to causecancer and reproductive harm. Wash handsafter handling. Use the vehicle's connection points in the engine compartment to connect an external start batteryor battery charger. The battery terminals on the car's starter battery in the luggage/cargo area must
not be used.
If the start battery is being charged, the support battery will also be charged.
