charged, the vehicle can no longer be
locked or unlocked. It is recommended to
have the batteries replaced at an autho-
rized 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.

CR 2025 or equivalent.
Remove the mechanical key out of the
SmartKey (
page 344).

(page 244) before folding the wiper
arms away from the windshield. You
could otherwise damage the hood
and/or the wiper arm.
