Important notes on using KEYLESS-GO

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(

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.
