Engine compartment overview
This overview shows some service-related com- ponents.
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 maintenance.
WARNING
Orange wiring may only be handled by quali- fied personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case ofan incorrect procedure.
• Do not touch anything that is not clearly described in this Owner's Manual.
• Be careful when checking/filling fluids inthe engine compartment.
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.

NOTE

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.
