Passlock
Your vehicle is equipped with the Passlock
-
theft deterrent system.
Passlock is a passive theft
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
If the engine stalls and the SECURITY message flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see "Fuses
and Circuit Breakers" in the Index). See your dealer
for service.
In an emergency, call the GM Roadside Assistance
Center. See "Roadside Assistance" in the Index.
