2022 Volvo XC40 Your Volvo Starting and switching off the car
Immobilizer
The following error message in the driver display is related to the electronic immobilizer:
| Symbol | Message | Specification |
|---|---|---|
 |
Car key not found | Error reading the key during starting – place the key on the key symbol in the center console’s storage compartment and try again. |
Starting the car
Start button location.
- Fasten the seatbelt.
- Adjust the seat, steering wheel, and mirrors.
- Make sure that the brake pedal can be fully depressed.
The key is not physically used when starting the car since it is equipped with support for keyless starting (Passive start).
To start the car:
The key must be inside the car. For cars with Passive Start, the key needs to be located in the front part of the passenger compartment. With the option for keyless locking/unlocking of the car, the key can be anywhere in the car. Hold the brake pedal depressed fully. For cars with automatic gear changing, make sure that gear position P or N is selected. For cars with a manual gearbox, make sure that the gear lever is in a neutral position or that the clutch pedal is depressed. Press the start button. When the engine is started, the starter motor works until the engine is started or until its overheating protection triggers.
Error messages
If the Car key not found message is shown in the driver display when starting, place the key by the backup reader. Then try to start the car again.
Backup reader’s location.
When the key is positioned by the backup reader, make sure that there are no keys, metal objects, or electronic apparatus by the backup reader, (e.g. mobile phones, tablets, computers, or chargers). Several keys close to one another by the backup reader may cause interference with each other.
If the engine fails to start after 3 attempts – wait for 3 minutes before making a further attempt. Starting capacity increases if the battery is allowed to recover.
Always take the key out from the car when leaving the car and make sure the car’s electrical system is in ignition position 0 – especially if there are children in the car.
The idling speed can be noticeably higher than normal for certain engine types during cold starting. This is done in order that the emissions system can reach normal operating temperature as quickly as possible, which minimizes exhaust emissions and protects the environment.
Using jump starting with another battery
Jump starting requires access to another car’s 12V battery as well as jump leads.
Important
The charging points in mild hybrid-type cars are designed for only jump-starting the car itself. Do not use the charging points of mild hybrids to start other cars – the fuse for the charging circuit may be overloaded so that it stops working. In mild hybrid-type cars, a discharged starter battery may be caused by an overloaded fuse that prevents charging. If a fuse has been triggered, the message 12 V Battery Fuse failure Service required is shown in the driver display. Volvo recommends that an authorized Volvo workshop is contacted.
- Charging points for jump-starting own car. The appearance of the engine compartment may vary depending on the car model and equipment level.
- 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 jump lead’s 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).
- Attach the red jump lead’s other clamp onto the car’s positive charging point (2).
- Attach one of the black jumps lead 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.
- Start the engine in the car with the discharged battery.
Important
Do not touch the connections between the cable and the car during the starting attempt. There is a risk of sparks forming. 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
48 V voltage can be dangerous in the event of incorrect intervention. Do not touch anything on the batteries that are not clearly described in the owner’s manual.
- 48 V support battery must never be used for jump-starting.
- External electrical equipment must not, under any circumstances, be connected to the 48 V battery.
- The 48 V battery may only be serviced and replaced by a workshop – an authorized Volvo workshop is recommended.
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.
Note
If the starter battery has such a low State Of Charge (SoC) that the car has no normal electrical functions and the engine is then jump-started with an external battery or a battery charger, the Start/stop function may continue to be activated. If the Start/stop function then auto-stops the engine shortly afterward, there is a great risk that the engine auto-start will fail because the battery has not had the time to recharge sufficiently. If the car has been jump-started, or if there is insufficient time to charge the battery using a battery charger, the Start/stop function will be temporarily deactivated until the battery has been sufficiently recharged by the car. In an outside temperature of approx. +15 °C (approx. 60 °F), the battery needs to be charged for at least 1 hour by the car. In a lower outside temperature, the charging time may increase to 3–4 hours. The recommendation is to charge the battery if possible using an external battery charger.
Switching off the car
Start button location.- To switch off the car:
- Press the start button – the car is switched off.
- If the gear selector for cars with an automatic gearbox is not in position P or if the car rolls:
- Press the start button and hold it depressed until the car is switched off.
Ignition positions
| Level | Functions |
|---|---|
| 0 |
In this mode, the functions are controlled by time and are switched off automatically after a short while. |
| I |
Power is taken from the battery in this ignition position. |
| II |
This ignition position consumes a lot of current from the battery and should therefore be avoided! |
Selecting ignition mode
Selecting ignition position
Start button location.
- Ignition position 0 – Unlock the car and store the key inside the car.
- Ignition position I – Depress the start button and release.
- Ignition position II – Press and hold the button depressed for approx. 5 seconds. Then release the button.
- Back to ignition position0 – To return to ignition position 0 from positions I and II – press the start button.
