I worry about topping them up fully to 38 in cold weather. What happens when the weather gets warm?

Let them down again….

Everything suggests the warning should clear within 10 miles (used to happen almost instantly on my Veloster) but this is the first time I have ever had the warning on the i5 and it refuses to go away. It is very cold in the UK right now, not sure if that could make a difference?

You need to inflate the tyres more to clear the fault. They should be at a min of 36psi when cold.
