CHANGE ENGINE OIL
This message is displayed when the engine oil
needs to be changed.
When you change the engine oil, be sure to reset
the CHANGE ENGINE OIL message. See
Engine Oil Life System (Gasoline Engine) on
page 489,Engine Oil (Gasoline Engine) on
page 486, andScheduled Maintenance (Gasoline
Engine) on page 617for more information.
CHARGING SYSTEM FAILURE
On some vehicles, if there is a problem with the
generator and battery charging system, this
message will appear on the DIC, a chime will
sound, and the battery warning light on the
instrument panel cluster will come on. Driving with
this problem could drain the battery. Turn off all
unnecessary accessories. Stop and turn off
the vehicle as soon as it is safe to do so. Have
the electrical system checked by your dealer
immediately. SeeBattery Warning Light on
page 253andVoltmeter Gage on page 253for
more information.
CHECK OIL LEVEL
If your vehicle has an oil level sensor, and the oil
level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct
it as necessary. You may need to let the vehicle
cool or warm up and cycle the ignition to be
sure this message will clear. Once the problem is
corrected, pressing any of the four DIC buttons
will acknowledge the message and clear it from the
DIC display. If your vehicle does not have the
four DIC buttons, pressing the trip odometer reset
stem will acknowledge the message and clear
it from the DIC display. SeeEngine Oil (Gasoline
Engine) on page 486for additional information.
CHECK WASHER FLUID
If the washer uid level is low, this message will
appear on the DIC. SeeWindshield Washer
Fluid on page 516. Adding washer uid to the
windshield washer reservoir will clear the
message. Pressing any of the four DIC buttons
will acknowledge the message and clear it from the
DIC display. If your vehicle does not have the
four DIC buttons, pressing the trip odometer reset
stem will acknowledge the message and clear
it from the DIC display.
272

If your vehicle has a low coolant level sensor, this
message will appear on the DIC if the engine
coolant level is low. Adding coolant to the coolant
recovery tank will clear the message. See
Cooling System on page 508. Pressing any of the
four DIC buttons will acknowledge the message
and clear it from the DIC display. If your
vehicle does not have the four DIC buttons,
pressing the trip odometer reset stem will
acknowledge the message and clear it from the
DIC display.
OIL LIFE RESET
This message will appear on the display for about
10 seconds after resetting the change engine
oil message. See “Engine Oil Life System” under
DIC Operation and Displays on page 266and
Engine Oil (Gasoline Engine) on page 486
for more information.
OIL PRESSURE LOW
Notice:If you drive your vehicle while the
engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the Driver Information
Center (DIC), stop the vehicle as soon as
possible. Do not drive the vehicle until the
cause of the low oil pressure is corrected. See
Engine Oil (Gasoline Engine) on page 486
for more information.
If low oil pressure levels occur, this message will
be displayed on the DIC and a chime will
sound. Stop the vehicle as soon as safely possible
and do not operate it until the cause of the low
oil pressure has been corrected. Check the oil as
soon as possible and have your vehicle serviced
by your dealer. SeeEngine Oil (Gasoline Engine)
on page 486.

What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.
If you have to add coolant more than four times a
year, have your dealer check your cooling
system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system,
you could damage your vehicle. Use only the
proper mixture of the engine coolant listed
in this manual for the cooling system.
SeeRecommended Fluids and Lubricants
on page 629for more information.

Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant and
the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the
coolant surge tank
pressure cap when
the cooling system,
including the coolant
surge tank pressure
cap and upper
radiator hose, is no
longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn. If you hear a hiss, wait
for that to stop. A hiss means there is
still some pressure left.
