2023 Volvo XC40 Recharge Plug-in Hybrid Battery Owners Manual

The key’s battery needs to be replaced when the information symbol is illuminated and the Car key battery low message is shown in the driver display.
Another sign that the battery level is low is decreased range for the key.

The battery in the Key tag (Key Tag) cannot be replaced. When the battery is discharged, a new Key tag can be ordered from an authorized Volvo workshop.

Important

Hand in a discharged Key Tag to an authorized Volvo workshop where it can be deleted from the car’s system. The key can still be used to start the car via backup start when the battery has been discharged.

Opening the key and changing its battery

Important

Avoid touching the contact surfaces of a new battery with your fingers. This impairs the battery’s functionality.
Hold the key so that its front with the Volvo logotype is facing up, and with the keyring bracket facing you.
There is a catch on the left of the keyring bracket. If it is on the wrong side then the front and rear have been mixed up when the battery was replaced on an earlier occasion.

Slide the catch by the keyring bracket to the side, and slide the front shell away from the bracket.
The shell detaches and can be lifted off.
There is a further catch under the shell to detach the rear.

Slide the catch that was behind the front shell to the side, and slide the rear shell away from the key ring bracket.
The shell detaches and can be lifted off.
The battery cover is under the shell.

Turn the battery cover anticlockwise to the OPEN position. Use a screwdriver or a coin, for example.
Lift off the battery cover. If it is difficult to detach, you can prize it upward using a narrow tool.

The battery (+) side is facing upwards. Loosen the battery by pressing on its edge and then lifting it out.

Install a new battery with the (+) side up. Avoid touching the key’s battery contacts with your fingers.
Position the edge of the battery under the two outer plastic catches.
Then press down on the battery so that it is held in place by the upper plastic catch.

Note
Use batteries with the designation CR2032, 3 V.

Note
Volvo recommends that replacement batteries for the key meet the UN Manual of Test and Criteria, Part III, sub-section 38.3. The batteries that are included or the batteries used for replacement by an authorized Volvo workshop will meet the same criterion.

Refit the battery cover and turn clockwise to the CLOSE position.

Refit the rear shell in reverse order to how it was removed. There is no logotype on the rear shell. Press in the shell until you hear a click, and then slide it the last few millimeters to its original position.
A further click will indicate that the shell is properly positioned and securely attached.

There must be no gaps remaining.

Turn the key and refit the front shell in the same way as for the rear.

Warning
Check that the battery is fitted correctly with the correct polarity. If the key shall not be used for a long time, remove the battery to avoid battery leakage and damage. Batteries with damaged or leaks may cause corrosive injury on contact with the skin. Therefore, use protective gloves when handling damaged batteries.

Keep batteries out of the reach of children.
Do not leave batteries lying around since they can be swallowed by children or pets.
Batteries must not: be dismantled, short-circuited, or thrown into open flames.
Do not try to charge non-rechargeable batteries. They may explode.
Check battery-operated products for signs of damage on a regular basis.
The key should not be used if anything indicates that the key or its battery has been damaged or has started to leak. Keep defective products out of the reach of children.

Important
Used batteries must be recycled in an environmentally sound manner.

Long-term storage of cars with hybrid batteries

To minimize the risk of damage to the hybrid battery during long-term storage (longer than 1 month) it is recommended that the state of charge (SoC) is maintained at approximately 25%. Check the charge level in the driver display on a regular basis.

Before long-term storage

Recommended state of charge (SoC) for long-term storage is approximately 25%.

If the state of charge (SoC) is high – drive the car until it reaches the recommended level.
If the state of charge (SoC) is low – charge the car to the recommended level.

During long-term storage

Check the state of charge (SoC) in the driver display on a regular basis.
Charge the car if the state of charge (SoC) has fallen noticeably, or if it has not been charged for longer than 6 months. This compensates for the natural self-discharge of the battery.

Note
Store the car in a cool place and avoid extreme temperatures during long-term storage in order to minimize the risk of battery damage. Select a storage location indoors or in the shade, depending on where the temperature is lowest, particularly in a hot climate.

Overloading the starter battery

High power consumption without the car being able to charge the starter battery leads to low battery levels and some electric functions being reduced or switched off. If the battery level decreases to below a certain limit, it is not possible to start the car without jump starting or charging with an external charger.
There are several measures that reduce power consumption. Avoid using the ignition position II when the car is switched off. Instead, use ignition position I – which consumes less power. Do not use functions that use a lot of power when the car is not being driven. Examples of such functions are:

ventilation fan
headlamps
windscreen wiper
audio system
accessories that are activated in the car.

If the battery level is low, a message is shown on the driver display. The energy-saving function then shuts down certain functions or reduces certain functions such as the ventilation fan and audio system.
In which case, charge the starter battery by starting the car and then running it for at least 15 minutes. Starter battery charging is more effective while driving than with the engine running at idling speed at stationary. If the battery level continues to be low after the measures have been taken, the car should be checked at a workshop. An authorized Volvo workshop is recommended.

Note
High current take-off may lead to a low battery level, which temporarily limits the start/stop function. The engine then starts automatically without the driver lifting his/her foot from the brake pedal. For cars with a manual gearbox, the start/stop function is deactivated without the clutch pedal being depressed if the gear lever is in a neutral position. The start/stop function will be available again when there is a sufficient level in the battery.

Using jump starting with another battery

If the car’s starter battery (12 V) is discharged then the car’s electrical system can be started with current from another battery.
If the battery with a voltage of 12 V (starter battery) is discharged, the car’s electrical system can be started by means of jump-starting using jump leads and another car. If the hybrid battery is also discharged, it will need to be charged using a charging cable after starting the electrical system in order to be able to start the engine.

Charging points for jump-starting own car. There are two connection points under the cover. Only use the one closest to the passenger compartment.

Important

The car’s charging points are only intended for jump-starting the car itself. Do not use them to start other cars – the fuse for the charging circuit may be overloaded so that it stops working.
If a fuse has been overloaded, the message 12 V Battery Fuse failure Service required is shown in the driver display. Volvo recommends that an authorized Volvo workshop is contacted.
When jump-starting the car, the following steps are recommended to avoid short circuits or other damage:

Set the car’s electrical system in ignition position 0.

Check that the donor battery has a voltage of 12 V.
If the battery is installed in another car – switch off its engine and make sure that the cars do not touch each other.
Connect one of the red jumps lead clamps to the donor battery’s positive terminal (1).

Important

Connect the jump lead carefully to avoid a short circuit and contact with other components in the engine compartment.
Open the positive charging point’s cover (2).
There are two connection points under the cover. Only use the connection point closest to the passenger compartment.
Attach the red jump lead’s other clamp onto the car’s positive charging point (2).
Attach one of the black jump lead’s clamps to the donor battery’s negative terminal (3).
Attach the black jump lead’s other clamp onto the car’s negative charging point (4).
Check that the jump lead clamps are affixed securely so that there are no sparks during the starting attempt.
Start the engine of the donor car and allow it to run for a few minutes at a rotation speed higher than normal idle approx. 1500 rpm.
Hold down the start button for at least 5 seconds without your foot on the brake to activate the car’s electrical system.

Note
In normal conditions, only the car’s electric motor is used for starting, and the internal combustion engine doesn’t start until it is needed during driving. That the car has started is indicated by the driver display illuminating and its indicator lamps being extinguished.

Important

Do not touch the connections between cable and car during the starting attempt. There is a risk of sparks forming.
Wait at least 2 minutes in order to charge the starter battery and then make a start attempt.
If the attempt at starting fails, repeat points 11 and 12.

Note

The car cannot be started if the hybrid battery is discharged.
Remove the jump leads in reverse order – first the black and then the red.
Make sure that none of the black jump lead’s clamps comes into contact with the car’s positive charging point, the donor battery’s positive terminal, or the clamp connected to the red jump lead.

Warning

The battery can generate oxyhydrogen gas, which is highly explosive. A spark can be formed if a jump lead is connected incorrectly, and this can be enough for the battery to explode.
Do not connect the jump leads to any fuel system component or any moving part. Be careful of hot engine parts.
The battery contains sulphuric acid, which can cause serious burns.
If sulphuric acid comes into contact with eyes, skin, or clothing, flush with large quantities of water. If acid splashes into the eyes – seek medical attention immediately.
Never smoke near the battery.

Batteries and power supplyThe car’s own power supply is connected to several different batteries and components. These make it possible to use the car’s electrical functions.
 The car’s primary electrical system operates with 12 V voltage and powers electrical equipment.
 In addition to the primary electrical system, the car has a high voltage system for electrical propulsion.
Warning
 Several components in the car work with a high-voltage current that could be dangerous in the event of incorrect intervention. Do not touch anything that is not clearly described in the owner’s manual.

Batteries

In order to supply power to the various components, your car is equipped with the following:

a 12 V starter battery that powers the car’s primary electrical system
a hybrid battery for the electrical propulsion of the car.

Recycling the batteries

Used batteries must be recycled in an environmentally sound manner.
Consult a workshop in the event of uncertainty about how this type of waste should be discarded – an authorized Volvo workshop is recommended. The hybrid battery must only be handled by authorized workshop personnel.

Symbols on the batteries

There are information and warning symbols on the batteries.

	Use protective goggles.
	Further information is in the owner’s manual for the car.
	Store the battery out of the reach of children.
	The battery contains corrosive acid.
	Avoid sparks and naked flames.
	Risk of explosion.
	Must be taken for recycling.

Hybrid batteryThe hybrid battery powers the car’s electric motor and is charged via the car’s charging input socket.
Note
 The car cannot be started if the hybrid battery is discharged.
 If both the starter battery and the hybrid battery are discharged then both batteries must be charged. In such a case, charging only the hybrid battery is not possible. In order for the hybrid battery to be charged, the starter battery must have a certain state of charge.

Warning
The hybrid battery must only be replaced by a workshop – an authorized Volvo workshop is recommended.

The service life and capacity of the hybrid battery

The hybrid battery’s capacity diminishes with age and use, which may result in increased use of the internal combustion engine and, as a consequence, reduced fuel economy and reduced range in electric drive.

Coolant

The hybrid battery’s cooling system has a separate expansion tank.

Important
The hybrid battery’s coolant must only be topped up by a workshop – an authorized Volvo workshop is recommended.

Specifications for hybrid battery

Type: Lithium-ion

The total amount of energy: 10.7 kWh

Starter battery

The starter battery powers the car’s primary electrical system, which includes most of the electrical equipment. The hybrid battery is used for starting the internal combustion engine.
The starter battery is a 12 V battery that is dimensioned to power the car model’s specific electrical system and functions.

Never disconnect the starter battery when the engine is running.
Check that the cables to the starter battery are correctly connected and properly tightened.

Important
On certain models, the battery is attached with a retaining strap. Make sure the retaining strap is properly tightened.

Important
If the battery is replaced, make sure you replace it with a battery with the same size, cold starting capacity, and type as the original battery (see the decal on the battery). Volvo recommends that you use an authorized Volvo workshop for replacing the battery.

Warning
If the starter battery is disconnected, the automatic opening and closing function must be reset to work properly. A reset must take place for pinch protection to work.

Warning

The battery can generate oxyhydrogen gas, which is highly explosive. A spark can be formed if a jump lead is connected incorrectly, and this can be enough for the battery to explode.
Do not connect the jump leads to any fuel system component or any moving part. Be careful of hot engine parts.
The battery contains sulphuric acid, which can cause serious burns.
If sulphuric acid comes into contact with eyes, skin, or clothing, flush with large quantities of water. If acid splashes into the eyes – seek medical attention immediately.
Never smoke near the battery.

The service life and capacity of the starter battery

The service life of the starter battery is influenced by a number of factors, such as the number of starts, discharges, driving style, driving conditions, and climate conditions. The battery’s starting capacity gradually decreases over time. Extreme cold further limits starting capacity. The battery level may become low if the car is not used for any length of time or if it only travels short distances. To keep the starter battery in good condition, at least 15 minutes of driving a week is recommended or connecting the battery to a battery charger with automatic trickle charging. A starter battery that is kept fully charged has a maximum service life.

Location

The starter battery is located in the cargo area.
