Vehicle Messages
The Driver Information Center (DIC)
will display warning messages if a
problem is detected. Pressing the
select button or the set/reset button
for vehicle with DIC buttons, or the
trip odometer reset stem for
vehicles without DIC buttons,
will acknowledge some current
warning or service messages.
Other messages are more urgent
and cannot be cleared from the
display until the issue is corrected.
The following are some additional
messages that the Duramax Diesel
vehicle can display.
Engine Cooling System
Messages
COOLANT LEVEL LOW
ADD COOLANT
Notice: Engine damage from
running your engine without
coolant is not covered by your
warranty. See “Overheated
Engine Protection Operating
Mode” in the Index of your
owner's manual for information
on driving to a safe place in an
emergency.
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 “Engine
Coolant” in the owner manual.
Engine Oil Messages
ENGINE OIL LOW ADD OIL
If your vehicle has an oil level
sensor, this message displays
if the oil level in the vehicle is low.
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
clears.
This message clears itself after
10 seconds, until the next ignition
cycle. See Engine Oil on page 10‑7
for additional information.
Engine Power Messages
ENGINE POWER IS REDUCED
A computer monitors the operation
of the electric accelerator. If the
ENGINE POWER IS REDUCED
message comes on while driving,
there will be a reduction in
performance and acceleration.
You should take the vehicle in
for service.
