1. Turn off the engine and allow the car to cool down.
2. Locate the dashboard light bulbs. They are located behind the instrument cluster, which is the panel in front of the steering wheel.
3. To access the instrument cluster, you will need to remove the trim panel that surrounds it. This can be done by carefully prying it off with a flat-head screwdriver.
4. Once the trim panel is removed, you will see the instrument cluster. The dashboard light bulbs are located at the top of the instrument cluster.
5. To remove a bulb, gently twist it counterclockwise and pull it out of its socket.
6. Insert the new bulb into the socket and twist it clockwise to secure it.
7. Repeat steps 5 and 6 for all of the dashboard light bulbs.
8. Once all of the bulbs have been replaced, reinstall the trim panel.
9. Turn on the engine and test the dashboard lights to make sure they are working properly.
Here are some additional tips for changing the dashboard lights in a Mercedes SLK 230:
* Use the correct type of bulbs. The dashboard light bulbs in a Mercedes SLK 230 are typically T5 or T10 bulbs.
* Be careful not to drop the bulbs. If a bulb drops, it can break and shatter the glass.
* If you have difficulty removing a bulb, you may need to use a pair of needle-nose pliers.
* Be careful not to touch the bulbs with your bare hands. The oils from your skin can cause the bulbs to burn out prematurely.
* If you have any questions about changing the dashboard lights in your Mercedes SLK 230, please consult a qualified mechanic.
