Important notes on using KEYLESS-GO R
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(Y page 252).
R You can combine KEYLESS-GO functions
with normal SmartKey functions (e.g.
unlocking with KEYLESS-GO and locking
with button &).
R Always carry the SmartKey with you.
R Never store the SmartKey together with
-electronic items
such as a mobile phone
or another SmartKey
- metallic objects such as coins or metal
foil Doing so could impair the function of the
KEYLESS-GO system.
R To lock
or unlock the vehicle, the SmartKey
must be located outside the vehicle within
approximately 3 ft (1 m) of a door or the
trunk.
R When the vehicle has been parked for more
than 72 hours, the KEYLESS-GO function is
deactivated. Pull an outside door handle
and switch on the ignition once to activate
the KEYLESS-GO function.
R If the SmartKey is positioned farther away
from the vehicle, the system may no longer
recognize the SmartKey. The vehicle
cannot be locked or the engine started via
the KEYLESS-GO system.
R If the SmartKey is removed from the vehicle
(e.g. if a passenger exits the vehicle with
the SmartKey)
-when pressing the KEYLESS-GO start/
stop button or trying to lock the vehicle
with the outside door handle the
message Key Not Detected appears in
the multifunction display
- with the engine running, the red message
Key Not Detected appears in the
multifunction display while driving off
Find the SmartKey or change its present
location immediately (e.g. place it on the
front passenger seat or insert it in shirt
pocket).
R If you have started the engine with the
KEYLESS-GO start/stop button, you can
turn it off again by
-pressing the KEYLESS-GO start/stop
button
- inserting the SmartKey into the starter
switch when the vehicle is at a standstill

until the engine has cooled. If necessary, call
the fire department. G
Warning!
You could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G

The amount of oil your engine consumes will
depend on a number of factors, including
driving style. Increased oil consumption can
occur when the vehicle is new or the vehicle
is driven frequently at higher engine speeds.
Engine oil consumption checks should only
be made after the vehicle break-in period.
! Do not use any special lubricant additives,
as these may damage the drive assemblies.
Using special additives not approved by
Mercedes-Benz may cause damage not
covered by the Mercedes-Benz Limited
Warranty.
For further information contact an
authorized Mercedes-Benz Center.
