How do you put a Mercedes e350 in gear with a dead battery?

To put a Mercedes E350 in gear with a dead battery, you need to manually override the shift lock. First, locate the shift lock release slot, usually found near the gear shifter and covered by a small plastic cap. Remove the cap, insert a flathead screwdriver or similar object into the slot, and press down while simultaneously moving the gear shifter to the desired position. Make sure to do this with the ignition in the "on" position if possible, as this may help with steering and brake functions.
