WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac-
tivate the double lock function by deactivat-
ing the interior motion sensor (see the sepa-
rate COMAND Online or Audio 20 operating
instructions). The doors can then be opened
from the inside after the vehicle has been
locked from the outside. The anti-theft alarm
system is triggered if the door is opened from
the inside. Switch off the alarm (Y page 90).

Important safety notes G
WARNING
The vehicle exhaust system can become very
hot. If you use HANDS-FREE ACCESS, you
could burn yourself by touching the exhaust
system. There is a risk of injury. Always
ensure that you only make a leg movement
within the detection range of sensors.
! If the key is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the unin-
tentional opening of the tailgate:

R using a high-pressure cleaner 106
Luggage compartmentOpening and closing

Make sure that the key is at least 3
maway
from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the tailgate or
stop the procedure without using your hands. This is useful if you have your hands full. To do
this, make a kicking movement under the
bumper with your foot.
Observe the following points:
R Carry your KEYLESS-GO key about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clear-
ance to the rear of the vehicle. You could
otherwise lose your balance, e.g. on ice. R
Always ensure that you only make a kicking
movement within the detection range of
sensors :.
R Stand at least 30 cm away from the rear
area while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Oth-
erwise, the sensors may not function cor-
rectly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R If a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HANDS-
FREE ACCESS could be triggered. The tail- gate could thus be opened or closed unin-
tentionally, for example, if you:
- fold the ball coupling in or out
- couple or uncouple a trailer
- fit or remove a rear-mounted bicycle rack
- load/unload bicycles on/from a rear-
mounted bicycle rack
- sit on the edge of the luggage compart-
ment
- set down or lift up an object behind the
vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key about
your person in such situations. This will
prevent the unintentional opening/closing
of the tailgate.
R Dirt caused by road salt around sensors :
may restrict functionality.
R Using HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
