Use medium and low heat settings for the majority of cooking on all heat sources, and allow the pan to heat gradually and evenly.
When searing meat, poultry or fish, a medium high heat can be used initially, but once the pan is hot and the food added, the heat should be lowered.
The pan should never be used on the highest heat setting for either preheating or cooking. Excessive surface temperatures will damage the nonstick cooking surface. See section on details of misuse.
Always use a stovetop burner that is similar in size to the base of the pan. Gas flames must always be confined to the base area and never extend up the sidewalls of the pan.
On any glass-topped stove always lift the pan to move it. Never slide the pan, as this may cause damage to the stovetop or the base of the pan.
The maximum safe temperature for oven use is 500°F / 260°C. When used under a hot broiler there should be a minimum distance of two inches (5cm) between the heat source and the top rim of the pan.

Add a little oil or fat to the cooking surface before heating begins. This will improve the flavor and browning of foods. At no time should the oil or fat become hot enough to smoke. If this occurs, cool the pan before proceeding. For fat-free cooking, preheat the pan on a medium heat setting for approximately two minutes before adding the food.
Do not leave the pan unattended during this time or allow the dry nonstick surface to overheat, as permanent damage may occur.

Cool the pan for a few minutes before cleaning. Do not plunge a hot pan into cold water.
Only recommended nonstick cleaning pads should be used on the nonstick surfaces. Do not use any metal or abrasive pads or abrasive cleaning agents on any of the surfaces.
The pan is dishwasher safe, but washing by hand is recommended. Simply wash with hot, soapy water, and rinse and dry thoroughly. If the pan is regularly washed in the dishwasher some darkening of the rivets and outer ring of the base may occur, or a powdery white deposit may form. This is normal and will not affect the performance of the pan. The surface dulling or white deposits can be removed by carefully cleaning the affected areas with a gentle nylon pad and detergent. After cleaning, rinse and dry thoroughly.
Each time the pan is cleaned in the dishwasher, the cooking surface should be re-conditioned with vegetable or corn oil before the next use.

The Le Creuset lifetime warranty does not cover damage to the nonstick surface caused by overheating or scratching.
Overheating: Damage from overheating during cooking is instantly recognizable. The nonstick surface becomes discolored, and in severe cases will blister or peel away from the pan.
Scratching: Score marks or severe scratching caused by heavy use of metal tools is not covered by the warranty. Such damage is permanent and will result in a reduction of the nonstick release performance.
