Security Warning Light
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
R
system has entered a
tamper mode. If the vehicle fails to start, see “Passlock”
in the Index.
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” in the Index for
additional information regarding the SECURITY light.
Service AWD Light
This light should come on
briefly when you turn on the
ignition, as a check to show
you it is working.
The SERVICE AWD light comes on to indicate that
there may be a problem with the drive system and
service is required. Malfunctions can be indicated by the
system before any problem is apparent, which may
prevent serious damage to the vehicle. This system is
also designed to assist your service technician in
correctly diagnosing a malfunction.
