HANDS-FREE ACCESS
Important safety notes
GWARNING
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 make the kicking movement
only within the detection range of the sensors.
!If the SmartKey is within the rear detectionrange of KEYLESS-GO, the following situa-tions, for example, could lead to the uninten-tional opening of the trunk lid:
Rwhen using an automatic car wash
Rwhen using a power washer
Make sure that the SmartKey is at least 10 ft(3 m) away from the vehicle.
iYou can also deactivate KEYLESS-GO. Fur-ther information on deactivating and activat-ing KEYLESS-GO (Ypage 71).
General notes
With KEYLESS-GO and HANDS-FREE ACCESS,you can open the trunk lid without using yourhands. This is useful if you have your hands full.To do this, make a kicking movement under thebumper with your foot.
Observe the following points:
RCarry your KEYLESS-GO key about your per-son. The SmartKey must be at the rear of thevehicle in the detection range of KEYLESS-GO.
RWhen making the kicking movement, makesure that you are standing firmly on theground and that there is sufficient clearanceto the rear of the vehicle. You could otherwiselose your balance, for example on ice.
RAlways ensure that you only make the kickingmovement within the detection range of sen-sorsC.
RStand at least 12 in (30 cm) away from therear area while doing so.
RDo not come into contact with the bumperwhile making the kicking movement. Other-wise, the sensors may not function correctly.
RHANDS-FREE ACCESS does not function dur-ing engine start.
RDirt caused by road salt or snow around sen-sorsCmay restrict functionality.
Using the HANDS-FREE ACCESS with a pros-thetic leg may restrict functionality.
RIf a KEYLESS-GO key is at the rear of the vehi-cle in the detection range of KEYLESS-GO,HANDS-FREE ACCESS could be triggered.The trunk lid could thus be opened uninten-tionally, for example, when you:
-set something down or lift something upbehind the vehicle.
-polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about yourperson in these situations or in situations sim-ilar to these. This will prevent the uninten-tional opening of the trunk lid.
