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
door handle. If your key is valid, the doors
will unlock, and you can open them.
Grasp the door handle.
The 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 SmartKey
with KEYLESS-GO 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 SmartKey with KEYLESS-GO
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
serious personal injury.
