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 boot lid opening unintentionally:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the boot lid 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.

erwise, the sensors may not function cor-
rectly.

tentionally, for example, if you:
- 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 boot.
