Engine compartment overview
This overview shows some service-related com- ponents.
The layout of the engine compartment may vary depend- ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver's side)
Washer fluid filler pipe 11
Fusebox
Air filter
Engine oil filler pipe
WARNING
Bear in mind that the cooling fan (located at the front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off. Always entrust engine washing to a workshop – an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicle electrical system should always be in ignition mode
0
when work in being performed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system is in igni- tion mode II or when the engine is warm.

Engine oil
For the recommended service intervals and war- ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
11 Fill the washer fluid at regular intervals, e.g. when refueling.

NOTE
If the conditions for measuring oil level are not 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 does not mean that anything is wrong in the vehi-
cle systems.

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.

MAINTENANCE AND SERVICE

563
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse order.
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 and rear fog light can be changed without the help of a work-shop. 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. If you are experiencing problems with any lights other than light bulbs, contact a workshop 14
. 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.

MAINTENANCE AND SERVICE

CAUTION
Only a modern battery charger with controlled charge voltage should be used to charge thestarter battery and support battery. The rapidcharging function should not be used as thiscould damage the battery.
CAUTION
Failure to observe the following could cause the infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
• The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
NOTE
If the starter battery becomes discharged too many times, it will shorten its service life. The service life of the starter battery is affec- ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity. To keep the starter battery in a good condi- tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging. A starter battery that is always kept fully charged has the maximum service life.
Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
CAUTION
On certain models, the battery is secured with a tensioning strap. Make sure that the ten-sioning strap is always securely tightened.

MAINTENANCE AND SERVICE
578
Avoid smoking, open
flames, and/or sparks.
Risk of explosion.
Recycle properly.
NOTE
A used start battery or backup battery con- tains lead and must be recycled in an environ-mentally responsible manner.

Fuses and fuseboxes
All electrical functions and components are pro- tected by a number of fuses in order to protectthe vehicle's electrical system from damage byshort circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possiblylead to a fire.
If any electrical component or function is not responding, the component may have blown afuse due to temporary overload. If the same fuseblows repeatedly, there may be a problem withthe component. Volvo recommends contacting anauthorized Volvo workshop to have the compo-nent checked.

MAINTENANCE AND SERVICE

Cleaning rims The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new. Wash the vehicle in a carwash or garage with an oil separator. Use a carwashing detergent.
RimsOnly use rim cleaning products recommended by Volvo. Strong rim cleaning agents could damage the surface and stain the chromed aluminum rims.

Corrosion protection
Your vehicle is constructed with effective protec- tion against corrosion.
Corrosion protection for the body consists of modern metallic protective coatings on the sheetmetal, a high-quality painting process, corrosion-protected and minimized metal overlap, andshielding plastic components, abrasion protectionand supplemental rust inhibitor in exposed areas.In the chassis, exposed components of the wheelsuspension are made of corrosion-resistant castaluminum.
Inspection and maintenanceThe corrosion protection does not normallyrequire maintenance, but keeping the vehicleclean is always a good way to further reduce therisk of corrosion. The use of strong alkaline oracidic cleaning fluids should always be avoidedon shiny body components. Any stone chips inthe paint should be touched up as soon as theyare discovered.
