WARNING
The vehicle exhaust system can become very
hot. If you unlock the luggage compartment
with KEYLESS-GO, you could burn yourself by touching the exhaust system. There is a risk of
injury. Always ensure that you only make the required kicking movement within the detec-
tion range of the 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 tailgate:
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 Vehicles with KEYLESS-GO without carbon
package:
you can unlock the tailgate without
using your hands. This is useful if you have your hands full. To do this, make a kicking movement
under the rear bumper with your foot.

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

movement within the detection range of sen- sors :.
R Stand at least 30 cm away from the rear area
while doing so.
