Remove the oil dipstick (located as per your user manual) and wipe it with a clean rag. To check the oil level stop the engine and let it cool for at least 3 minutes. Make sure your vehicle is level (i.e not on a side stand) and in a neutral gear if applicable, and start the engine, letting it idle for a couple of minutes (and even longer in cold weather): this lets the engine oil lubricate all the engine's internal workings. Also make sure you have enough fuel for your journey. Check the Fuel lines for any signs of leakage or deterioration, and make sure the pipes are not pinched or blocked in any way. Firstly, always keep your fuel tap set to 'OFF' when your vehicle is not in use, and be careful not to switch onto reserve useage instead of the main reservoir when operating the tap.
