NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by your warranty.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
Security 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
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 Four-Wheel-Drive Warning Light
(If Equipped)
This light should come on
briefly when you turn on
the ignition, as a check to
show you it is working.
The SERVICE 4WD 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.
