boot, the boot lid opens again after it is closed.
It does not lock. HANDS-FREE ACCESS
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 situations, 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 use-
ful 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 per-
son. 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 a kicking
movement within the detection range of sen-
sors :.
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. Other-
wise, the sensors may not function correctly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R Dirt caused by road salt around sensors :
may restrict functionality.
R Using HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
R If a KEYLESS-GO key is within the rear detec-
tion range of KEYLESS-GO, HANDS-FREE
ACCESS could be triggered. The boot lid could thus be opened or closed unintentionally, for
example, if you:
- sit on the edge of the boot
- 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. Boot
