Practical hints

Unlocking/locking in an emergency

If the batteries in the SmartKey or the KEY-
LESS-GO* card are discharged, the vehicle 
can no longer be locked or unlocked. It is 
recommended to have the batteries re-
placed at an authorized Mercedes-Benz 
Center.

Batteries contain materials that can harm 
the environment if disposed of improperly. 
Recycling of batteries is the preferred 
method of disposal. Many states require 
sellers of batteries to accept old batteries 
for recycling.
