HANDS-FREE ACCESS
Important safety notes G
WARNING
The vehicle's exhaust system may be very hot.
You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking
movement within the detection range of
sensors.
! If the key is within the rear detection
range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
R using a car wash
R using a power washer
Make sure that the key is at least 6.5 ft
(2 m) away from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk lid
or stop the procedure without using your
hands. This is useful if you have your hands
full. To do this, simply move your foot under
the bumper.
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
clearance to the rear of the vehicle. You
could otherwise lose your balance e.g. on
ice. R
Always ensure that you only make the
kicking movement within the detection
range of sensors 0043.
R Stand at least 12 in (30 cm) away from the
rear area while doing so.
R Do not come into contact with the bumper
while making the kicking movement.
Otherwise, the sensors may not function
correctly.
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, HAND-
FREE ACCESS could be triggered. The trunk
lid could thus be opened or closed
unintentionally, for example, if you:
-set something down or lift something up
behind the vehicle
- polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about
your person in these situations or in
situations similar to these. This will prevent
the unintentional opening/closing of the
trunk.
R Using the HANDS-FREE ACCESS with a
prosthetic leg may restrict functionality. 94
