32 Getting startedUnlockingUnlocking with KEYLESS-GO*
Vehicles with KEYLESS-GO*: in addition to
the two SmartKeys with remote controls
and removable mechanical key, your vehi-
cle comes equipped with two KEY-
LESS-GO* cards.
The function of the SmartKey overrules the
KEYLESS-GO function.If you have the KEYLESS-GO function, your
vehicle checks whether the KEYLESS-GO
card is valid when you grasp the door han-
dle. If your KEYLESS-GO card is valid, the
doors will unlock, and you can open them.
Grasp the door handle.
All turn signal lamps blink once. The
locking knobs on the doors move up.
Pressing the KEYLESS-GO start/stop but-
ton on the selector lever corresponds to
turning the key to the various starter
switch positions.
iTo unlock the vehicle, the KEYLESS-GO
card must be outside the vehicle, no
further than approx. 3 feet (1 meter)
away from the door.
Warning!
G
When leaving the vehicle, always take the
key and the KEYLESS-GO card with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.
