112 Controls in detailLocking and unlockingImportant notes on using KEYLESS-GO*
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 106).
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 ap-
proximately 3 ft (1 m) of the respective
door or the tailgate.
In order to start the engine with the
SmartKey with KEYLESS-GO:
The SmartKey with KEYLESS-GO
must be located in the vehicle.
All doors must be closed.
The brake pedal must be firmly de-
pressed. Do not depress the accel-
erator.
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 the SmartKey with KEYLESS-GO is re-
moved from the vehicle while starter
switch position1 (e.g. if passenger ex-
its the vehicle with the SmartKey with
KEYLESS-GO), the message
Key not
recognized
will appear in the multi-
function display while driving off.
Find the SmartKey with KEYLESS-GO or
change its present location immediate-
ly (e.g. place it on the front passenger
seat or insert it in shirt pocket).
