These
Operating Instructions describe all the
models and standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific differences
are possible. Bear in mind that your vehicle
may not be equipped with all the functions
described. This also applies to safety-relevant

Keys
General notes
Your vehicle is equipped with a special key
system.
Only if you have keys that are coded for the
vehicle, can you:
R
switch on the ignition
R
start the engine
R
engage the gears
i
If
a vehicle key is lost, obtaining a replace-
ment is a time-consuming process. This
can only be done through a Mercedes-Benz
Service Centre.
Mercedes-Benz therefore recommends
that you always keep an easily accessible
replacement key with you for emergencies.
If you lose a key, have it disabled at a
Mercedes-Benz Service Centre. This pre-
vents the lost key from being misused.
Key variants
Key without remote control
Key with remote control
Multifunction key
Your
vehicle can be equipped with one or sev-
eral of the following key variants:
R
key without remote control
R
key with remote control
R
multifunction key
You can use the % and & buttons to
operate the central locking and the conveni-
ence opening and closing functions
(Y page 65).
The remote control works regardless of the
direction in which it is pointed. You can lock/
unlock the vehicle from a distance of up to
approximately 30 m. Only use the remote
control in the immediate vicinity of the vehi-
cle. This helps to prevent theft.
The key with remote control contains a bat-
tery. When this remote control battery is dis-
charged, the on-board computer displays an
appropriate event window. Replace the bat-
tery in the key (Y page 68).
