Engine compartment overview
The overview shows some service-related com- ponents.
The appearance of the engine compartment may differ depending on model and engine variant.
Coolant expansion tank
Reservoir for brake and clutch fluid (located on the driver's side)
Washer fluid filler pipe 7
Central electrical unit
Air filter
Engine oil filler pipe
WARNING
Remember that the radiator fan (located at the front of the engine compartment, behindthe radiator) may start automatically someafter the engine has been switched off. Always have the engine cleaned by a work- shop - an authorised Volvo workshop is rec-ommended. There is a risk of fire if the engineis hot.
WARNING
The ignition system works at a very high and hazardous voltage. The car's electrical system must always be in ignition position
0 when
work is being performed in the engine com- partment. Do not touch the spark plugs or ignition coil when the car's electrical system is in ignition position II or when the engine is hot.

Engine oil
An approved engine oil must be used in order that the recommended service intervals can beapplied.
Volvo recommends:
IMPORTANT
In order to fulfil the requirements for the engine's service intervals all engines are filledwith a specially adapted synthetic engine oilat the factory. The choice of oil has beenmade very carefully with regard to service life,starting characteristics, fuel consumption andenvironmental impact. An approved engine oil must be used in order that the recommended service intervals canbe applied. Only use a prescribed grade of oilfor both filling and oil change, otherwise thereis a risk of the service life, starting characte-ristics, fuel consumption and environmentalimpact of the car being affected. If engine oil of the prescribed grade and vis- cosity is not used, engine related componentsmay become damaged. Volvo Car Corporationdisclaims any liability for any such damage. Volvo recommends that oil changes are car- ried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/ high oil level or low oil pressure. Certain enginevariants have an oil pressure sensor, and then thedriver display's warning symbol for low oil pres- sure
is used. Other variants have an oil
level sensor, when the driver is informed via the driver display's warning symbol
and display texts. Certain variants have both systems. Contact a Volvo dealer for more information. Change the engine oil and oil filter in accordance with the intervals specified in the Service andWarranty Booklet. Using oil of a higher than specified grade is per- mitted. If the car is driven in adverse conditions,Volvo recommends using an oil of a higher gradethan the one specified.

Checking and filling with engine oil The oil level is detected with the electronic oil level sensor.
Filler pipe8
.
In some cases, oil may need to be topped up between service intervals. Action with regard to engine oil level does not need to be taken until a message is shown in thedriver display.
WARNING
If this symbol is shown together with the message Engine oil level
Service required, visit a workshop
- an authorised Volvo workshop is
recommended. The oil level may be too high.
IMPORTANT
If this symbol is shown together with a message about low oil level, such as
Engine oil level low
Refill 1 litre for example, then only
fill the volume specified, e.g. 1 litre.
WARNING
Do not spill oil onto the hot exhaust manifold due to the risk of fire.
Check the oil level
1. Open the Car status app from the app view
in the centre display.
2. Press the
Status button to show the oil
level.
Graphics for oil level in the centre display.
The oil level is checked using the electronic oil level gauge in the centre display when the engineis switched off.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The car musthave been driven approx. 30 km and havebeen stationary for 5 minutes with the engineswitched off and on level ground before theoil level indication is correct.
8 Engines with electronic oil level sensor do not have a dipstick.

NOTE
If the right conditions for measuring the oil level (time after engine shutdown, the car'sinclination, outside temperature, etc.) are not met, then the message
No value availablewill be shown in the centre display. This does not mean that there is something wrong in
the car's systems.

Topping up coolant
The coolant cools the internal combustion engine to the correct operating temperature. Theheat that is transferred from the engine to thecoolant can be used to heat the passenger com-partment.
When topping up the coolant, follow the instruc- tions on the packaging. Never top up with wateronly. The risk of freezing increases with both toolittle and too much coolant concentrate.
WARNING
Coolant can be very hot. If the coolant requires topping up when the engine is atoperating temperature, unscrew the expan-sion tank cap slowly to gently release theoverpressure.
Coolant expansion tank, left-hand drive car.
Screw off the cap in the plastic cover.
Screw off the cap on the expansion tank and top up with coolant. The coolant level must not exceed the yellow MAX mark inside the
expansion tank.
Reinstall the parts in reverse order.

Coolant expansion tank, right-hand drive car.
Grip the hatch's handle and lift/jiggle the hatch from the plastic cover.
Screw off the cap on the expansion tank and top up with coolant. The coolant level must not exceed the yellow MAX mark inside the
expansion tank.
Reinstall the parts in reverse order. If there is coolant under the car, if there is cool- ant smoke, or if more than 2 litres have beenfilled, always call for recovery to avoid the risk ofengine damage due to a defective cooling sys-tem when attempting to start the car.
IMPORTANT
• A high content of chlorine, chlorides and other salts may cause corrosion in thecooling system.
• Always use coolant with anti-corrosionagent as recommended by Volvo.
• Ensure that the coolant mixture is 50%water and 50% coolant.
• Mix the coolant with approved quality tapwater. In the event of any doubt aboutwater quality, used ready-mixed coolant inaccordance with Volvo recommendations.
• When changing coolant/replacing cool-ing system components, flush the coolingsystem clean with approved quality tapwater or flush with ready-mixed coolant.
• The engine must only be run with a well-filled cooling system. Otherwise, tempera-tures that are too high may occur result-ing in the risk of damage (cracks) in thecylinder head.

NOTE
Points to remember when the cover is refit- ted: •The pin in the clip needs to be pressed back fully before the clip is refitted in thecover.
• When the cover is refitted, the pin mustbe pressed in until the end surface islevel with the surface of the clip.
The reversing lamp bulb and the rear fog lamp bulb can be replaced without assistance from aworkshop. Contact a workshop 9
if there is a fault in bulbs
other than the bulbs in the halogen headlamps, the reversing lamp bulb or the rear fog lamp bulb. If a fault occurs in LED 10
lamps, the entire lamp
unit usually must be replaced.
WARNING
The car's electrical system must be in ignition position 0 when replacing bulbs.
IMPORTANT
Never touch the glass part of the bulbs with your fingers. Grease from your fingers isvaporised by the heat, coating the reflectorand then causing damage.
NOTE
If an error message remains after the broken bulb has been replaced then we recommendvisiting an authorised Volvo workshop.
NOTE
Outside lighting such as headlamps and rear lamps may temporarily have condensation onthe inside of the lens. This is normal, all exte-rior lighting is designed to withstand this.Condensation is normally vented out of thelamp housing when the lamp has beenswitched on for a time.
