I didn’t say that the SL doesn’t have a dipstick. Just saying that quite few engines don’t because they use other means to measure oil. Point is that an oil pressure garage is more rare for that reason.

Thank you. I've been in that section several times, but never thought to select engine data. Is there any way to change the readout to F vs C, or will I need to extrapolate? What is acceptable engine oil temp before driving hard? Also, is there a way to change Sat radio channels while this screen is up, besides displaying it on the screen between the tach and speedo? I completely rely on the digital speedo.

Re. the engine oil temp, the screenshot was from our car, so 100-110 degree Celsius is normal (215-230 degrees Fahrenheit)...
Since you don't want to give up the display in the instrument cluster for speed, you might want to select engine data screen as a Comand favorite (the star button left to the knob - center console) as well as the Sat radio station screen. This was you can quickly switch screens without using the menu hierarchy.

I fitted my first car with an oil pressure gauge, water temperature and ammeter - not sure what oil pressure told me but it looked cool.
I was taught to start the car and drive off (once visibility was acceptable) carefully (low revs) until the car was properly warmed up.

Where we live we are no stranger to sub zero temps (Fahrenheit, not Celsius) and I wouldn't bother waiting for the engine to warm up even then. Modern engines are designed for cold starts and start/stops, so the only time we use remote start is for us to be warm, not the engine

Thank you. Something else to figure out! Not at all familiar with Command favorites... yet. I did take note of the blue, white, then red colors on the oil temp dial, so that will be helpful as well. I'll do some C-F conversions so I know what the oil temp is doing. Would be nice to be able to quickly switch from engine dials to radio/media and vise versa. Thanks for the help. If I can't figure it out, I'll be back. Remember, this is my first Mercedes!

I live in a very temperate climate and I doubt that I ever start my SL when the temperature is less than 60 degrees F. But still, every time I fire her up, I wait for the rpm’s to settle down to an idle, before engaging the transmission. I figure, this gives the fluids a few seconds to circulate & get the juices flowing. I’m old, I’m retired, I’m never in a hurry.
