It is 50 miles (80 km) if the vehicle is partially loaded and 18 miles (30 km) if the vehicle is fully loaded.

If you use your vehicle mostly for shortdistance trips, you will need to have the battery charge checked more frequently. When replacing a battery, always use a battery approved by Mercedes-Benz. If you do not intend to operate your vehicle for an extended period of time, contact an authorized Mercedes-Benz Center about steps you need to observe. G Warning!

Avoid abrupt steering and driving maneuvers, as well as driving over obstacles (road curbs, potholes, or off-road areas). This is especially important if the vehicle is heavily loaded. The emergency driving distance that can be achieved greatly depends on the demands placed on the vehicle. Depending on speed, load, driving maneuvers, road conditions, outside temperature, etc., the distance can be significantly shorter or, if the vehicle is driven cautiously, somewhat longer. G Warning! Observe all safety instructions and precautions when handling automotive batteries. Z Practical hints After driving in emergency mode, you must have the rims inspected by an authorized Mercedes-Benz Center to check if they are suitable for further use. The failed tire must be replaced in any case.
