the security light on the instrument
panel comes on when trying to start
the vehicle, there may be a problem
with your theft-deterrent system.
Turn the ignition off and try again.
If the engine still does not start,
and the key appears to be
undamaged, try another ignition
key and check the fuses. See Fuses
and Circuit Breakers on page 10‑32
for additional information. If the
engine still does not start with the
other key, the vehicle needs service.

may be faulty. See your dealer who can service the PASS-Key
®III+
to have a new key made. In an
emergency, contact Roadside
Assistance. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
