SmartKey with KEYLESS-GO*
Vehicles equipped with KEYLESS-GO come with two SmartKeys with KEYLESS-GO, each with remote control and a removable mechanical key. The locking tabs for the mechanical key portion of the two Smart- Keys are a different color to help distin- guish each SmartKey unit.
The KEYLESS-GO function is integrated into the SmartKey. On these vehicles, the validity of the SmartKey with KEYLESS-GO is checked every time you grasp a door handle.
If the SmartKey with KEYLESS-GO is valid, your vehicle unlocks:
앫 the doors 앫 the trunk lid 앫 the fuel filler flap
!
If battery check lamp5 does not come on briefly during check, then the SmartKey batteries are discharged. Replace the batteries (컄page 349). You can obtain the required batteries at any authorized Mercedes-Benz Cen- ter.
