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:

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.
