SmartKey with KEYLESS-GO*
Specially equipped vehicles come with two
SmartKeys with KEYLESS-GO, each with
remote control and a removable mechani-
cal key. The locking tabs for the mechani-
cal key portion of the two SmartKeys are a
different color to help distinguish each
SmartKey unit.
The KEYLESS-GO function is integrated
into the SmartKey. On these vehicles, the
validity of the SmartKey with KEYLESS-GO
is checked every time you pull a door
handle.
iIf the trunk lid does not open, it is still
locked separately (if applicable)
(page 106)
If the vehicle was previously centrally
locked, the trunk lid will lock automati-
cally when closed (
page 100). The
turn signals will flash three times to
confirm locking.
!To prevent possible malfunction, avoid
exposing the SmartKey with
KEYLESS-GO to high levels of electro-
magnetic radiation.
