Reasons for xc60 auto start-stop not working?
2 Answers
Auto start-stop system not working may be mainly caused by accidentally pressing the auto start-stop button on the car, resulting in the system being turned off. Here are detailed reasons and solutions: 1. Misoperation: Vehicles equipped with auto start-stop function usually have the system enabled by default. If it's not working, it might be due to accidentally pressing the auto start-stop button, causing the system to shut down. Solution: Carefully check if the system has been turned off. 2. Non-operational conditions: Engine not reaching normal operating temperature, auto air conditioning not reaching preset temperature, insufficient battery charge, turning the steering wheel after stopping, emergency braking, reversing. Solution: Check if all temperatures are normal and the vehicle's status.
I've been driving an XC60 for three years and have encountered several instances where the start-stop system didn't work. The most common issue I found was related to the battery—the start-stop function requires sufficient battery charge to activate. If the battery is aging or frequently undercharged due to short trips, the system will automatically disable this feature to protect the battery. Another factor is having the air conditioning on high, which forces the engine to run continuously for cooling, effectively disabling the start-stop. Minor details like incorrect steering wheel angle or doors not fully closed can also trigger protective measures. It's worth noting that the start-stop system is quite sensitive to temperature, often not functioning below zero or above 35 degrees Celsius. My advice is to first check the battery condition; if that doesn't solve the issue, it's best to visit a dealership to read the fault codes for the exact cause.
