2003 Mercedes Benz S500 oil level

TO CHECK LEVEL: From the odometer screen on cluster use "arrow up" one time. Screen should read something about measuring oil on level ground only. A few seconds later screen should read "add" "ok" "reduce."

TO ADD: Fill at left (drivers side) valve cover oil port, best to use synthetic oil. If it reads "add 1qt" recommend only adding about a.5 qt, wait about 5 minutes and re-check. System is sensitive to overfill and will tell you "oil level too high" while driving if overfilled.
