Locking and unlocking
Important notes on using KEYLESS-GO*
You can also use the SmartKey with 
KEYLESS-GO like a normal SmartKey 
(
page 110).
You can combine KEYLESS-GO func-
tions with normal SmartKey functions 
(e.g. unlocking with KEYLESS-GO and 
locking with the ‹button).
Always carry the SmartKey with 
KEYLESS-GO with you.
Never store the SmartKey with 
KEYLESS-GO together with
electronic items such as a cellular 
phone or another SmartKey with 
KEYLESS-GO
metallic objects such as coins or 
metal foil
Doing so could impair the function of 
the KEYLESS-GO system.
To lock or unlock the vehicle, the 
SmartKey with KEYLESS-GO must be 
located outside the vehicle within 
approximately 3 ft (1 m) of the respec-
tive door or the tailgate.
If the vehicle has been parked for more 
than 72 hours, you must pull an outside 
door handle in order to activate the 
KEYLESS-GO function
In order to start the engine with the 
SmartKey with KEYLESS-GO:
The SmartKey with KEYLESS-GO 
must be located in the vehicle.
The KEYLESS-GO start/stop button 
must be inserted in the starter 
switch (
page 41).
The brake pedal must be firmly 
depressed. Do not depress the 
accelerator.
If the SmartKey with KEYLESS-GO is 
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO. 
The vehicle then cannot be locked or 
the engine started via the KEYLESS-GO 
system.
If you have started the engine with the 
KEYLESS-GO start/stop button 
(
page 54), you can turn it off again by
pressing the KEYLESS-GO 
start/stop button (
page 66)
inserting the SmartKey into the 
starter switch when the vehicle is at 
a standstill and the automatic 
transmission is in position P 
(
