Change Oil Soon Light (If Equipped)
This light is activated
by the Engine Oil Life
Monitor System.
The CHANGE OIL SOON light turns on for three
seconds as a bulb check each time the ignition key is
turned to RUN. It will stay on for 60 seconds once
90 percent of the oil life has been used and each time the
engine is started after that. If the CHANGE OIL SOON
light is on continuously, there is a problem with the
Engine Oil Life Monitor System and service is required.
The Engine Oil Life Monitor determines the condition
of the engine oil and lets you know when the oil should
be changed. See “Engine Oil” in the Index.
The Engine Oil Life Monitor receives information about
engine speed, coolant temperature and vehicle speed to
determine how much the oil has degraded.
When to change your oil depends on your driving habits
and conditions. The CHANGE OIL SOON light may
turn on as early as 2,000 miles (3 218 km) or less for
harsh circumstances.
For additional information, see “Engine Oil, When to
Change” in the Index. To reset the Oil Life Monitor, see
“Engine Oil Life Monitor” in the Index.
Cruise Light
The cruise light comes on
whenever you set your
cruise control. See “Cruise
Control” in the Index.
Washer Fluid Low Light (If Equipped)
When the vehicle has a low
fluid condition, this light
will come on to remind
you to get more washer
fluid soon.
