- All batteries have a limited service life and must eventually be replaced (does not apply to Key Tag). The service life of the battery varies depending on how often the vehicle/key is used.
- The key’s battery needs to be replaced when the information symbol is illuminated and The car key battery is low. See Owner’s Manual for replacement. the 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 authorised Volvo workshop.
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 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.
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 millimetres 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.
Check that the battery is fitted correctly with the correct polarity. If the key shall not been used for a long time, remove the battery to avoid battery leakage and damage. Batteries with damage 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.
Recommendations for high voltage battery
Some circumstances may lead to damage to the high voltage battery and shorten its service life. The recommendations are designed for long service life for the high voltage battery and good performance while driving.
When possible and timely, select AC charging in preference to DC fast charging. AC charging is more sparing on the high voltage battery, especially with regular charging.
High State Of Charge (SOC)
- Avoid charging the car to 100% unless the full range is needed for the journey.
- The battery may be damaged by maintaining a very high State Of Charge (SOC) for a long time. Therefore, avoid leaving the car connected for charging to more than the recommended charge level, which is shown in the centre display.
Low State Of Charge (SOC)
Important
- The high voltage battery may be seriously damaged if it is not charged after being fully discharged. Since there is also a certain amount of consumption and self-discharge when the car is not in use, the State Of Charge (SOC) can fall to 0% if the car is left unconnected with a low State Of Charge (SOC).
- If the State Of Charge (SOC) is below 20%, charging is always recommended to avoid the battery is fully discharged.
To minimise the risk of damage to the battery during long-term parking (longer than one month), it is recommended to have a charging range of 40-60%.
- If the State Of Charge (SOC) is higher – drive the car until the State Of Charge (SOC) is lower.
- If the State Of Charge (SOC) is lower – charge the car.
If you plan to park the car for longer than three months, it is recommended that you connect it to constant charging.
Check the car’s State Of Charge (SOC) on a regular basis, as well as that charging is working properly.
Parking in a hot climate
Avoid exposing the car to extreme temperatures. If there is a risk of temperatures around 55 °C (131 °F) then parking for longer than 24 hours should be completely avoided in order to avoid serious damage to the battery.
- High temperatures can damage the high voltage battery, especially if it is exposed for a long time. If possible, avoid leaving the car unconnected at temperatures higher than 30 °C (86 °F). The car can actively cool the battery while it is parked, but this consumes power and leads to a fall in the State Of Charge (SOC). If the car is charged while it is parked the battery can be cooled without being discharged.
- If possible, park in the shade if the outdoor temperature is high. Strong sunlight in combination with high outdoor temperature may lead to the car and the high voltage battery becoming very hot.
Parking in a cold climate
- In a low temperature for the high voltage battery, performance is temporarily reduced until the battery is heated. Connect the car for charging and use preconditioning to avoid driving with reduced performance. The car can then heat the battery prior to driving without the State Of Charge (SOC) and range falling.
- Connect the car for charging if parking for longer than 24 hours is planned, while the ambient temperature is below -30°C (-22°F).
- Driving the car while there is an indication of reduced performance due to low temperature will not be harmful.
Using jump starting with another battery
If the car does not start, it may be due to the 12V battery being discharged. It can be charged using another car’s 12 V battery or an external charger.
Under normal conditions, the 12V battery is charged at the same time as the car is charged, as well as via current transmission from the high voltage battery when the car is not connected for charging.
If the 12V battery is discharged for any reason, jump-starting can still be used. This may be caused by the car not being used for a long time, a temporary fault, or a blown fuse in the car’s charging circuit. A discharged 12 V battery needs to be recharged in order to start the car and power its electrical system. After starting, it is possible to start charging the car using the charging cable, which will be necessary if the high voltage battery is also discharged. If the car is out of reach for charging in such a situation, it may need recovery.
You need jump leads in order to use jump starting and these are connected to the car’s charging points for the 12 V battery.
You will need to remove a number of panels under the bonnet in order to access the charging points.
Important
- The car’s charging points are only intended for jump-starting the car itself. The charging points are not intended for jump-starting another car. Using the charging points for jump-starting another car may cause a fuse to blow, which means the charging points will stop working.
- If the message 12 V battery fuse failure Service required is shown in the driver display then a fuse has blown and needs to be changed. Volvo recommends that an authorized Volvo workshop should be contacted.
Several of the panels around the storage area need to be loosened for access to the charging points under the bonnet.When jump-starting the car, the following steps are recommended to avoid short circuits or other damage:
- Set the car’s electrical system in Passive usage mode.
- 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
Handle the jump leads with care. A short circuit may occur if the ends come into contact with surfaces other than the charging points. - Open the cover (2) for the positive charging point by pressing on its side. This disengages a hook and you can lift the cover-up at the same time. There are two connection points under the cover. Use it closest to the centre of the car.
- Attach the red jump lead’s other clamp onto the car’s positive charging point (2).
- Connect 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. Poor contact may cause sparks or the clamps to loosen during the starting attempt.|
- Start the engine of the donor car.
- Start the car that has the discharged battery by keeping your foot on the brake and selecting gear position D or R.
Note
- Full starting is indicated by means of the driver display’s indicator lamps extinguishing and its preset theme illuminating.
- If the high voltage battery is also discharged, start charging the car with the charging cable.
- Remove the jump leads in reverse order – first the black and then the red.
- Make sure that the black jump lead’s clamps do not come into contact with the car’s positive charging point, the donor battery’s positive terminal, or the red jump lead’s clamps.
Warning
- The 12 V 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.
- The 12 V 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 supply
- The 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.
In order to supply power to the various components, your car is equipped with the following:
- a 12 V battery that powers the car’s primary electrical system
- a high voltage battery for 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 authorised Volvo workshop is recommended. The hybrid battery must only be handled by authorised workshop personnel.
- Consult a workshop in the event of uncertainty about how this type of waste should be discarded – an authorised Volvo workshop is recommended. The high voltage battery must only be handled by authorised workshop personnel.
