we have a 2017 diesel sport. starting to get cold in the mornings. How does one activate the glow plugs? This is a stupid question probably, but i dont feel like the glow plugs are automatically activating if they are suppose to? I know on my ford f350, i turn the key to on, the glow plug lights up and you wait until the glow plug light goes out, then i can start the truck. What is the procedure for the range rover diesel? thank you complete noob to the range rover
