Engine compartment overview
This overview shows some service-related components.
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.

Checking and filling engine oil (p. 555)
Ignition modes (p. 381)
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,

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 approximately30 km (20 miles) and have been stationary5 minutes on a level surface and with theengine off before the correct oil level willbe displayed.
NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engineshutdown, vehicle inclination, ambient temperature, etc.) the message
No value
available will be shown in the center dis-
play. This does not mean that anything is
wrong in the vehicle systems.

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.

Replacing bulbs
Bulb types vary depending on model and equipment level. If a light bulb 15
breaks, it can
be replaced by following the procedure shown in the Owner's Manual. If you are experiencing problems with any lights other than light bulbs, contact a work- shop 16
.
If there is a problem with an LED 17
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.
WARNING
The vehicle electrical system must be in ignition mode 0 when bulbs are replaced.
CAUTION
Never touch the bulb glass with your bare fingers. Grease and oils from your fingersvaporize in the heat and will leave adeposit on the reflector, which may dam-age it.
NOTE
If the error message persists after the defective bulb has been replaced, we rec-ommend a visit to an authorized Volvoworkshop.
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.
