If the oil is below the cross-hatched area (L)
for the 4.2L L6 engine or below the
cross-hatched area at the tip of the dipstick for
the 5.3L V8 engine, you will need to add at least
one quart/liter of oil. But you must use the
right kind. This section explains what kind of oil
to use. For engine oil crankcase capacity,
seeCapacities and Speci cations on page 445.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above
the cross-hatched area (F) that shows the
proper operating range for the 4.2L L6 engine
or above the cross-hatched area for the
5.3L V8 engine, the engine could be damaged.SeeEngine
Compartment Overview
on page 330for the
location of the engine
oil ll cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range.
Push the dipstick all the way back in when
you are through.

When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE ENGINE OIL message
will come on in the Driver Information Center
(DIC). SeeDIC Warnings and Messages
on page 199. Change the oil as soon as
possible within the next 600 miles (1 000 km).
It is possible that, if you are driving under the best
conditions, the oil life system may not indicate
that an oil change is necessary for over a
year. However, the engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your dealer has trained
service people who will perform this work and reset
the system. It is also important to check the oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km)
since the last oil change. Remember to reset the
oil life system whenever the oil is changed.How to Reset the Engine Oil Life System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a CHANGE ENGINE
OIL message being turned on, reset the system.
To reset the Engine Oil Life System, do the
following:
1. Use the fuel button on the Driver Information
Center to reach the ENGINE OIL LIFE screen.
2. Press and hold the select button on the
Driver Information Center ve seconds
while ENGINE OIL LIFE is displayed.
3. OIL LIFE RESET will appear on the Driver
Information Center (DIC) display for
10 seconds to let you know the system
is reset.
If the CHANGE ENGINE OIL message comes
back on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
