You can use the buttons to set various functions for your appliance. The display shows the settings.
If a function is active, the corresponding symbol lights up in the display. The clock symbol
only lights up when you change the time.
Symbol | Function | Use |
![]() | Time-setting options | Select the time To select the individual time-setting options, press the button sev- eral times. |
![]() | Minus Plus | Decrease the setting values. Increase the setting values. |
![]() | Childproof lock | Activate or deactivate the childproof lock. |
To ensure that you always use the right type of heating to cook your food, we have explained the differences and ap- plications below.

Symbol | Type of heating | What it's used for/how it works |
![]() | 3D hot air | Bake and roast on one or more levels. The fan distributes the heat from the ring-shaped heating element in the back wall evenly around the cooking compartment. |
![]() | Gentle hot air | Cook selected dishes gently on one level without preheating. The fan distributes the heat from the ring-shaped heating element in the back wall evenly around the cooking compartment. The food is cooked in phases us-ing residual heat. Select a temperature of between 120 °C and 230 °C. This type of heating is used to determine the energy consumption in air recircu-lation mode and the energy efficiency class. |

Symbol | Type of heating | What it's used for/how it works |
![]() | Top/bottom heating | Bake on one level. The heat is emitted evenly from above and below. This type of heating is used to measure the energy consumption in the conven-tional mode. |
![]() | Grill, small area | Grill small quantities of steak, sausages or toast. Brown small quantities of food. The central area underneath the grill element becomes hot. |
![]() | Full-surface grill | Grill flat items such as steak, sausages, or toast. Brown food. The entire area underneath the grill element becomes hot. |

There are different settings for the types of heating and functions.
Note: For temperature settings above 250 °C, the appliance reduces the temperature to approx. 240 °C after ap- prox. 10 minutes. If your appliance has the top/bottom heating or bottom heating types, this temperature reduction does not take place.

The heating-up indicator for the oven remains lit while the appliance is heating.
Note: Due to thermal inertia, the temperature displayed may differ slightly from the actual temperature inside the cooking compartment.

When the main oven
heats up, the symbol
also lights up in the display. This symbol goes out when heating is paused.
The functions in the cooking compartment make your appliance easier to use.
The rails in the cooking compartment enable you to place accessories at different heights.
→ "Accessories", Page 9
The shelf positions are numbered from bottom to top.
You can remove the rails, e. g. for cleaning.
→ "Shelf supports", Page 15

The cooking compartment has five shelf positions.

Top cooking compartment 
The cooking compartment has three shelf positions.

The self-cleaning surfaces in the cooking compartment are coated with a porous, matt ceramic layer and have a rough surface. When the appliance is in operation, the self-cleaning surfaces absorb splashes from roasting or grilling and break them down.
The following surfaces are self-cleaning:

The oven light lights up the cooking compartment.
With most types of heating and functions, the lighting lights up during operation. When the function selector is turned to bring operation to an end, the lighting goes out.
The Oven light setting on the function selector can be used to switch on the light without heating.
The cooling fan switches on and off depending on the appliance's temperature. The hot air escapes above the door.
ATTENTION!
Do not cover the ventilation slot above the appliance door. The appliance overheats.
Ensure that the ventilation slots are unobstructed.
To ensure that the appliance cools down more quickly after operation, the cooling fan continues to run for a certain period afterwards.
If you open the appliance door during operation, the operation continues.
Use original accessories. These have been made especially for your appliance.
Note: Accessories may become deformed if they get hot. Deformation has no effect on function. As the accessory cools down, it will regain its original shape.
The accessories supplied may differ depending on the appliance model.


The locking function prevents the accessories from tilt- ing when they are pulled out.
You can pull out the accessories approximately halfway without them tipping. The accessories must be inserted into the cooking compartment correctly for the tilt pro- tection to work properly.
Always slide accessories into the cooking compartment correctly. This is the only way to ensure that accessor- ies can be pulled out approximately halfway without tip- ping.
1.Turn the accessories so that the notch
is at the rear and is facing downwards.
2. Insert accessories between the two guide rods for the shelf position.


3. Push the accessory all the way in, making sure that it does not touch the appliance door.
Note: Take any accessories that you will not be using out of the cooking compartment while the appliance is in operation.
You can combine the wire rack with the universal pan to catch any liquid that drips down.
1.Place the wire rack on the universal pan so that both spacers
are on the rear edge of the univer- sal pan.
2. Insert the universal pan between the two guide rods for a shelf position. In so doing, the wire rack is on top of the upper guide rod.
