9. If the coolant level inside the
radiator filler neck is low, add
more of the proper DEX-COOL
coolant mixture through the
filler neck until the level is back
up to the base of the filler
neck. Replace the pressure cap.
Be sure to secure it tightly.
Notice: If the pressure cap is not
tightly installed, coolant loss
and possible engine damage may
occur. Be sure the cap is
properly and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gage on the instrument
panel cluster. See Engine Coolant
Temperature Gage on page 3-36.
The vehicle may also display
an ENGINE OVERHEATED IDLE
ENGINE and ENGINE
OVERHEATED STOP ENGINE
message in the Driver Information
Center (DIC). See DIC Warnings
and Messages on page 3-50.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
See Roadside Assistance Program
on page 7-6.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.
Notice: Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches fire
while driving with no coolant,
the vehicle can be badly
damaged. The costly repairs
would not be covered by
the vehicle warranty. See
Overheated Engine Protection
Operating Mode on page 5-24 for
information on driving to a
safe place in an emergency.
