Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent electrical shock.
Gather necessary tools and parts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the negative battery cable (black) first, then the positive (red).
2. Clean the battery terminals with a wire brush to remove corrosion.
3. If the battery voltage is low, replace the battery with a new one (ensure it's the correct type for the XC60).
4. Reconnect the positive cable first, followed by the negative cable.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor; it is typically near the engine block.
2. Disconnect the electrical wiring from the starter.
3. Test the starter by applying direct voltage from the battery; if it does not engage, replace the starter motor.
4. Reinstall the starter and reconnect the wiring.

4. Check and Replace Relay

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for location).
2. Remove the relay and test it with a multimeter for continuity.
3. If faulty, replace with a new relay of the same specification.
4. Reinstall the relay and ensure it clicks into place.
