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

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
