SmartKeys
Your vehicle comes supplied with two 
SmartKeys, each with remote control and 
a removable mechanical key. The locking 
tabs for the mechanical key portion of the 
two SmartKeys are a different color to help 
distinguish each SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is 
advisable to only unlock the vehicle when 
you are in close proximity to it.

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.

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.

KEYLESS-GO with you.
Never store the SmartKey with 
KEYLESS-GO together with:
electronic items such as a cellular 
phone or another SmartKey with
