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 move-
ment within the detection range of sensors.
! If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk: R
using a car wash R
using a power washer
Make sure that the SmartKey is at least 10 ft
(3 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 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 the kicking
movement within the detection range of sen-
sors C . 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. 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 C
may restrict functionality.
Using the 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 trunk lid
could thus be opened or closed unintention-
ally, for example, if you: -
sit on the edge of the trunk. -
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 sim-
ilar to these. This will prevent the uninten-
tional opening/closing of the trunk.92
