ENGINE COOLANT HOT
If the cooling system temperature gets hot, this
message will appear in the DIC. Turn off the
air conditioning. If the message is still on, or if the
engine coolant temperature gage continues to
rise, pull the vehicle over when it is safe to do so.
See Engine Coolant Temperature Gage on
page 178 for more information. Stop the vehicle
and let the engine idle in PARK (P) for a few
minutes to allow the coolant to reach a safe
temperature. This message will clear when the
coolant temperature drops to safe operating
temperature. Pressing any of the four DIC buttons
or the trip odometer reset stem will acknowledge
the message and clear it from the DIC display.
ENGINE OVERHEATED
Notice: If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears on
the instrument panel cluster and/or DIC, stop
the vehicle as soon as possible. Do not increase
the engine speed above normal idling speed.
See Engine Overheating on page 350 for more
information.
If the engine cooling system reaches unsafe
temperatures for operation, this message
will appear in the DIC and you will hear a chime.
Stop and turn off the vehicle as soon as it is
safe to do so to avoid severe damage. This
message will clear when the engine has cooled to
a safe operating temperature.
FUEL LEVEL LOW
If the fuel level is low, this message will appear on
the DIC and you will hear a chime. Refuel as
soon as possible. The message will be displayed
for 10 seconds at the start of each ignition
cycle when the fuel level is low. Pressing any of
the four DIC buttons or the trip odometer reset
stem will acknowledge the message and clear it
from the DIC display. See Low Fuel Warning Light
on page 185, Fuel Gage on page 185, and Fuel
on page 326.
