Hoisting the vehicle
When hoisting the vehicle, it is important that the jack is positioned on the designatedpoints under the vehicle.
For vehicles with Leveling Control* : If the
vehicle is equipped with pneumatic suspen- sion, this feature must be turned off before thevehicle is lifted onto a tow truck.
WARNING
If the vehicle is lifted on a garage jack, the jack must be placed under one of the fourlifting points. Make sure that the vehicle iscorrectly positioned on the jack and that itcannot slide off. Make sure the jack platehas a rubber pad to help keep the vehiclestable and prevent damage. Always useaxle stands or similar.
NOTE
Volvo recommends only using the jack intended for your specific vehicle model. Ifa jack other than that recommended byVolvo is used, follow the instructionsincluded with the equipment. The vehicle's ordinary jack is only intended to be used in temporary situations for shortperiods of time, such as when changingwheels in the event of a flat tire. If the vehi-cle needs to be lifted more frequently, orfor a longer period of time than for a wheelchange, a garage jack or hoist is recom-mended. Always follow the instructions foruse provided with the equipment.

Engine compartment overview
This overview shows some service-related components.
Some of the components included in the vehi- cle's electric drive system are located in theengine compartment. Exercise caution whenaccessing the engine compartment and onlytouch what is required for normal mainte-nance.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly.
Do not touch anything that is not clearly described in this Owner's Man-ual.
Be careful when checking/filling fluidsin the engine compartment.
The layout of the engine compartment may vary depending on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driv- er's side)
Washer fluid filler pipe 12
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartmentbehind the radiator) may start or continuerunning automatically up to about6 minutes after the engine is turned off. Always entrust engine washing to a work- shop – an authorized Volvo workshop isrecommended. If the engine is hot, there isa risk of fire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicleelectrical system should always be in igni-tion mode
0 when work in being per-
formed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system isin ignition mode II or when the engine is
warm.

Engine oil For the recommended service intervals and warranties to be applied, an approved engineoil must be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seri-ous engine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filled with a specially adapted syntheticengine oil. Great care has been put into thechoice of oil, with consideration given toservice life, startability, fuel consumptionand environmental impact. For the recommended service intervals to apply, an approved engine oil must beused. Only use the prescribed oil grade totop off or change the oil. Otherwise, thereis a risk of the vehicle's service life, starta-bility, fuel consumption and environmentalimpact being affected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Cor-poration disclaims warranty liability forsuch type of damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low.On engine variants with an oil pressure sensor,

a warning symbol is displayed in the instru- ment panel when oil pressure is low
. On
engine variants with an oil level sensor, the
warning symbol in the instrument panel
and display messages are used to alert the driver. Some engine variants have both sys-tems. Contact a Volvo retailer for more infor-mation. Change the engine oil and oil filter according to the schedule specified in the Warranty andMaintenance Records Information booklet.Oils of a higher grade than that specified maybe used. If the vehicle is driven in adverse con-ditions, Volvo recommends using an oil with ahigher grade than that specified.

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 instru-ment panel.
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 indicated 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 elec- tronic oil level gauge in the center display oncethe vehicle has been started. The oil levelshould be checked regularly.
13 Engines with an electronic oil level sensor do not have a dipstick.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heattransferred from the engine to the coolantcan be used to warm the passenger compart-ment.
When refilling coolant, follow the instructions on the package. Never fill the cooling systemwith only water. The risk of freezing isincreased with too low or too high amounts ofcoolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than2 liters (about 2 quarts) of coolant has beenadded to the system, there could be some-thing wrong with the cooling system and star-ting the vehicle could damage the engine. Calla tow truck and do not attempt to start theengine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. Ifcoolant must be filled, unscrew the expan-sion tank cap slowly to relieve overpres-sure.

MAINTENANCE AND SERVICE
577
Coolant expansion tank, left-hand drive vehicle.
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should notexceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in thereverse order.
CAUTION
Do not ingest the contents. May cause damage to organs (kidneys).
Use premixed coolant according toVolvo's recommendations. If concen-trated coolant is used, make sure thatthe coolant mixture is 50% coolantand 50% water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use newcoolant when replacing larger compo-nents in the cooling system.
Never run the engine unless the cool-ing system is properly filled. Animproperly filled cooling system couldlead to high temperatures and cracksin the cylinder heads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
This vehicle is equipped with only LED 16
lights, which means it does not have any replaceable bulbs. Contact a workshop 15
if
you experience any problems with the light- ing. If there is a problem with an LED 16
light, the
entire lamp unit will normally need to be replaced.
NOTE
For information on lights not mentioned in the Owner's Manual, contact a Volvodealer or a certified Volvo service techni-cian.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas 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 Volvoservice technician.
