32 Getting startedUnlockingUnlocking with KEYLESS-GO*
Your vehicle comes supplied with two
SmartKeys with remote controls and a re-
movable mechanical key. The locking tabs
for the mechanical key portion of the two
keys are a different color to help distin-
guish each key unit.
The function of the SmartKey overrules the
KEYLESS-GO function.
If you have the KEYLESS-GO function, your
vehicle checks whether the SmartKey with
KEYLESS-GO is valid when you grasp the
