This light will come on briefly when you turn the
key toward START. The light will stay on until the
engine starts.
If the light flashes, the Passlock@ system has entered a
tamper mode. If the vehicle fails to start, see Passlock@
on page 2- 18.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock@
system. Your vehicle will not be protected by Passlock@,
and you should see your dealer.
Also, see Content Theft-Deterrent on page 2- 17 for
additional information regarding the SECURITY light.
