Locking and unlocking
Automatic central locking
The doors and the tailgate lock automati-
cally when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
For information on towing the vehicle, see
“Towing the vehicle” (
page 538).
You can deactivate the automatic central
locking mode using the control system
(
page 180).
Locking and unlocking from the inside
You can lock or unlock the doors and the
tailgate from inside using the central lock-
ing or unlocking switch. This can be useful,
for example, if you want to lock the vehicle
before starting to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking or unlock-
ing switch.Even with the SmartKey with KEYLESS-GO*
removed from the vehicle, the tailgate
closing switch can be operated. Therefore,
do not leave children unattended in the vehi-
cle, or with access to an unlocked vehicle. A
child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
iTo prevent a possible inadvertent lockout,
the tailgate will open automatically if a SmartKey
with KEYLESS-GO* is recognized inside the
vehicle.
iYou can open a locked door from the inside.
Open door only when conditions are safe to do
so.
iThe doors unlock automatically after an
accident if the force of the impact exceeds a
preset threshold.
The vehicle automatically locks when the ignition
is switched on and the wheels are turning at
vehicle speeds of approximately 9 mph
(15 km/h) or more. You could therefore lock
yourself out when the vehicle

is pushed or towed

is on a test stand
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an
accident and/or serious personal injury.

!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
