KEYLESS-GO
Vehicles equipped with KEYLESS-GO come
with two SmartKeys with KEYLESS-GO, each
with remote control and a removable
mechanical key.
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 an outside door handle.
If the SmartKey with KEYLESS-GO is valid,
your vehicle unlocks

When you open a door, the side window on
that side lowers slightly. Once you close the
door, the window moves up again.
! A side window will not work if it is blocked
with ice or if the vehicle battery is dis-
charged. If you cannot shut a door, do not
force it or you could damage the door or
side window. Fix whatever is affecting the
window before trying to shut the door.
