Caution! Never change the program mode when the selector lever is out of position "P". It could result in a change of driving characteristics for which you may not be prepared. Important! Always be certain of the program mode selected since the vehicle driving characteristics change with the selection of the program mode. Dependent on the program mode selector switch position "S" or "W" and the gear selector lever in position "R", the ratio of power transmission changes. Emergency operation (Limp home mode) If vehicle acceleration worsens or the transmission no longer shifts, the transmission is most likely operating in Limp home mode which engages when there is a malfunction of the transmission. This condition may be accompanied by the "CHECK ENGINE" malfunction indicator lamp in the instrument cluster coming on. In this mode only the 2nd gear or reverse gear can be activated. To engage 2nd gear or reverse: 1. Stop the vehicle. 2. Move selector lever to position "P". 3. Turn off the engine. 4. Wait approx. 10 seconds. 5. Restart the engine. 6. Move selector lever to position "D" (for 2nd gear), or move selector lever to position "R" (for reverse gear). Have the transmission checked at your authorized Mercedes-Benz Center as soon as possible. With a malfunction in the vehicle's electrical system the selector lever may be locked in position "P". To unlock the selector lever manually, see page 274. Automatic transmission Instruments and controls Operation Driving 201 Instrument cluster display Practical hints Car care Technical data Index
