Unlocking/locking in an emergency

If you are unable to lock the vehicle with 
the SmartKey, lock it with the mechanical 
key as follows:

trunk.

cockpit (

chanical key (

왘

Check if the trunk is locked. If neces-
sary lock the trunk with the mechanical 
key (

If the batteries in the SmartKey are dis-
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.

G

Keep the batteries out of reach of children.

If a battery is swallowed, seek medical help 
immediately.

i

When changing batteries, always re-
place both batteries.

The required replacement batteries are 
available at any Mercedes-Benz 
Center.
