RTo open or close the vehicle, the KEYLESS-
GO key should be no more than 3 ft (1 m)
from the door or trunk.
RWhen the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull one of the outer door
handles and turn on the ignition to
reactivate the KEYLESS-GO function.
RIf the KEYLESS-GO key is not near the
vehicle, it is possible that the system may
not recognize it. In this case, the vehicle
cannot be locked or started with KEYLESS-
GO.
RIf the KEYLESS-GO key has been removed
from the vehicle (e.g. if a passenger leaves
the vehicle with the KEYLESS-GO key):
-while someone is holding the Start/Stop
button or attempting to lock the vehicle
with the outer door handle, the message
Key not detected appears in the
multifunction display
-while the engine is running, the red
message Key not detected appears in
the multifunction display as you pull
away. Find the KEYLESS-GO key or
change its current position immediately
(e.g. place it on the front-passenger seat
or carry it in your shirt pocket.)
RIf you have started the engine using the
Start/Stop button, you can turn if off again
by:
-pressing the Start/Stop button again
-inserting the KEYLESS-GO key in the
ignition lock when the vehicle is
stationary and the automatic
transmission is in parking position P.
RYou may accidentally unlock the vehicle if
the KEYLESS-GO key is within 3 ft (1 m) of
the vehicle and:
-an outer door handle comes into contact
with water
or
-you are cleaning an outer door handle.
RNote that the engine can be started by any
vehicle occupant if a KEYLESS-GO key is in
the vehicle.
Option 1: there is a KEYLESS-GO key in the
vehicle and a KEYLESS-GO key outside the
vehicle. If you leave the KEYLESS-GO key
behind when you get out and lock the
vehicle, a message does not appear in the
multifunction display.
Option 2: there is a KEYLESS-GO key in the
vehicle but no KEYLESS-GO key outside the
vehicle. When you get out and try to lock
the vehicle, the message Key still in
vehicle appears in the multifunction
display. The vehicle is not locked in this
case.
When starting the engine and while driving,
KEYLESS-GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact.
X To unlock the vehicle: touch the inner
surface of the door handle.
XTo lock the vehicle: touch sensor
surface :.
If you pull on the handle of the trunk lid, only

Automatic anti-glare mirrors
GWarning!
The auto dimming function does not react if
incoming light is not aimed directly at sensors
in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver's side do not
react, for example, if the rear window
sunshade is in raised position.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
glare mode if the ignition is switched on and
incident light from headlamps strikes the
sensor in the rear-view mirror.
The mirrors do not go into anti-glare mode if
reverse gear is engaged or the interior lighting
is switched on.

Replacing the wiper blades
Important safety notes
GWarning
For safety reasons, switch off the windshield
wipers and remove the key from the ignition
lock before changing the wiper blades
(vehicles with KEYLESS-GO: make sure that
the on-board electronics are in state 0).
Otherwise, the wiper motor could be switched
on suddenly and cause injury.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield can be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades replaced by a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center.
Replacing the windshield wiper blades
Removing the wiper blades
XRemove the key from the ignition lock or
turn the key to position 0 (KEYLESS-GO).
XFold the wiper arm away from the
windshield until it engages.
XSet the wiper blade at right angles to the
wiper arm.
XRemove the wiper blade from the retainer
on the wiper arm in the direction of the
arrow.
Installing the wiper blade
XSlide the new wiper blade into the retainer
on the wiper arm in the opposite direction
to the arrow.
Make sure that the wiper blade slides fully
into the retainer on the wiper arm.
XTurn the wiper blade parallel to the wiper
arm.
XFold the wiper arm back onto the
windshield.
Problems with the windshield wipers
The windshield wipers are obstructed
Leaves or snow, for example, may be
