STARTING AND DRIVING -> Emission control with AdBlue? for Your Volvo XC40 SUV Second Generation (2022-2026)

STARTING AND DRIVING  
|| When refuelling, check that the area around  
the fuel filler pipe is clean. Avoid spilling fuel  
onto the paintwork. Wash off any spillage with  
detergent and water.

Once the engine has stopped due to fuel star-  
vation, the fuel system needs a few moments  
to carry out a check.  
Before starting the car after the fuel tank has  
been filled with diesel - proceed as follows:  
Filling fuel (p. 441)  
Empty tank and diesel engine (p. 446)  
Diesel particulate filter (p. 447)  
Emission control with AdBlue® (p. 448)  
IMPORTANT  
Diesel fuel must:  
1. The remote control key must be inside the  
car.  
Fuel consumption and CO2 emissions  
(p. 659)  
fulfil the EN 590, EN 15940 and/or  
SS 155435 standards

2. Set the car in ignition position II – press  
the start button without depressing the  
brake pedal Or clutch pedal and hold the  
button depressed for approx. 4 seconds.  
Then release the button.

3. Wait approx. one minute.  
4. Start the engine.  
IMPORTANT  
Diesel type fuels that must not be used:  
NOTE  
Special additives  
Marine diesel fuel  
Heating oil

Before filling with fuel in the event of fuel  
shortage:  
Stop the car on as flat/level ground as  
possible - if the car is tilting there is a  
risk of air pockets in the fuel supply.

These fuels do not fulfil the requirements in  
accordance with Volvo recommendations  
and generate increased wear and engine  
damage that is not covered by the Volvo  
warranty.

area. Make sure you insert the funnel's pipe  
firmly into the filler pipe. The filler pipe has two  
opening caps. The funnel's pipe must be  
pushed past both caps before filling can be  
started.  
Diesel particulate filter  
Diesel cars are fitted with particle filters for  
more efficient emission control.  
IMPORTANT  
If the filter is completely filled with parti-  
cles, it may be difficult to start the engine  
and the filter is non-functional. Then there  
is a risk that the filter will need to be  
replaced.  
Particles in the exhaust gases are collected in  
the diesel particle filter during normal driving.  
When these conditions have been met, regen-  
eration starts to burn off the particles and  
empty the filter. To start regeneration, the  
engine must have reached normal operating  
temperature. Regeneration of the particulate  
filter is automatic and normally takes  
10-20 minutes.

When driving short distances at low  
speeds in a diesel car  
The capacity of the emissions system is affec-  
ted by how the car is driven. Driving varying  
distances and at different speeds is important  
in order to achieve performance that is as  
energy-efficient as possible.  
NOTE  
The following may arise during regenera-  
tion:  
Driving short distances at low speeds (or in  
cold climates) frequently, where the engine  
does not reach normal operating temperature,  
can lead to problems that can eventually  
cause a malfunction and trigger a warning  
message. If the vehicle is mostly driven in city  
traffic, it is important to regularly drive at  
higher speeds to allow the emissions system  
to regenerate.  
a smaller reduction of engine power  
may be noticed temporarily  
•
•
•
fuel consumption may increase tempo-  
rarily  
a smell of burning may arise.  
Use the parking heater* in cold weather - the  
engine then reaches normal operating tem-  
perature more quickly.  
The car should be driven on A-roads at  
speeds in excess of 60 km/h (38 mph) for  
at least 20 minutes between each refuel-  
ling.

Emission control with AdBlue®25

AdBlue. If something is wrong, a message is  
shown in the driver display.  
Related information  
Diesel (p. 445)  
AdBlue is an additive used in the SCR26 sys-  
tem to reduce emissions of noxious sub-  
stances from a diesel engine.  
•
•
•
Emission control with AdBlue® (p. 448)  
IMPORTANT  
Fuel consumption and CO2 emissions  
(p. 659)  
AdBlue is required for the function of the  
SCR system and legal emissions compli-  
ance. It is illegal to modify or manipulate  
the AdBlue supply system in any way so  
that no AdBlue reagent is consumed when  
it is required for legal exhaust emissions  
compliance. Any such tampering may be a  
criminal offence which may lead to legal  
prosecution actions.  
In the SCR system, the AdBlue and the nitrous  
oxide exhaust gas substance are converted to  
nitrogen and water vapour, which significantly  
reduces the emissions of harmful nitrous  
oxides.  
AdBlue  
AdBlue is a colourless liquid consisting of  
32.5% urea27 in deionised water and is manu-  
factured in accordance with the ISO 22241  
standard. It is specially developed for SCR  
cleaning technology for diesel engines.  
It is not permitted to operate the car with  
an empty AdBlue tank, since it will no  
longer be compliant with the legal require-  
ments for exhaust emissions. Therefore,  
the car is equipped with a warning system  
to inform when AdBlue refilling is required.  
When the fill level in the AdBlue tank is  
getting low, warnings are displayed to  
inform that AdBlue refilling is required.  
AdBlue has its own tank in the car which is  
topped up via a separate filler pipe behind the  
fuel filler flap. Consumption depends on driv-  
ing style, outside temperature and the operat-  
ing temperature of the system.  
Conditions for driving with AdBlue  
There must always be AdBlue of the correct  
quality in the AdBlue tank before the car can  
be started. The SCR system is very sensitive  
to contaminants.  
The emission control system continuously  
monitors the tank level, quality and dosage of

Storage  
Handling AdBlue® (p. 449)  
AdBlue must be stored in tightly sealing origi-  
nal packaging at a temperature above -11 °C  
(12 °F) and below 30 °C (86 °F). The fluid  
must not be stored in direct sunlight.  
AdBlue consists primarily of water (approx.  
67.5% water and 32.5% urea). The fluid is  
not flammable but should be handled with  
care since it can irritate the eyes and skin.

AdBlue freezes at -11 °C (12 °F) but can be  
used again when the solution has thawed.  
Points to remember when handling  
Avoid inhaling vapour as well as contact with  
skin and eyes. Preferably use gloves that pre-  
vent irritation to sensitive skin when handling  
the fluid.

WARNING  
Action for first aid:  
For inhalation - get fresh air.  
•
•
For skin contact - wash the skin with  
soap and water.  
For contact with the eyes - rinse imme-  
diately with a lot of water.  
•
•
For ingestion - rinse the mouth thor-  
oughly. Do not induce vomiting.  
Seek medical attention if the discomfort  
remains or if a large quantity has been  
ingested.  
Action in the event of a spill  
AdBlue spilled on the ground, the car or pain-  
ted surfaces must be rinsed thoroughly with  
water. Avoid releasing into the drainage sys-  
tem.

Checking and filling with AdBlue®  
Check the AdBlue level regularly and top up if  
the message for low AdBlue level is shown in  
the driver display.  
2.  
Checking AdBlue level  
1.  
The AdBlue consumption is dependent on  
driving style, if the AdBlue tank is allowed to  
drain completely then it will no longer be pos-  
sible to start the car.  
Press Status to show the AdBlue level.  
Open the Car Status app in the app view.  
NOTE  
Never run the AdBlue tank dry. Fill the tank  
in good time before it is empty.  
If the tank is run dry, it will not be possible  
to start the engine after it is switched off –  
not the regular way or using aids.  
The only way to be able to restart after  
driving the tank empty is to refill AdBlue of  
specified quality, with the minimum being  
the quantity shown in the driver display.  
Graphic for AdBlue level in the centre display.  
Each cursor represents approx. 25% of a  
full tank.  
When less than 25 % of the tank remains  
available, the colour of the remaining cur-  
sor changes to amber, and at less than  
10 % it turns red.

3. Fill slowly/in portions, in order to avoid air  
pockets.  
Filling with AdBlue  
When the AdBlue level starts  
to become low, a symbol illu-  
minates in the driver display  
and the AdBlue level low  
message is shown.  
WARNING  
When filling from the AdBlue pump at a fill-  
ing station, it is advisable to use the pump  
adapted for passenger cars. The AdBlue  
pump for heavy vehicles can also be used.  
Do not overfill the tank. The amount of AdBlue  
that can be filled is shown in the app Car  
Status.  
IMPORTANT  
Use AdBlue of the correct quality 29  
Wipe away any spilled AdBlue.  
1. Open the fuel filler flap with a gentle press  
on the rear of the flap.  
Exercise caution to prevent AdBlue from  
coming into contact with the car's paint-  
work. If it does, rinse with plenty of water  
since the fluid can affect the paintwork.
