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.
If coolant is needed, add the proper DEX-COOL ®
coolant mixture at the coolant recovery tank.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
There is an engine temperature warning light and/or
gauge on the instrument panel cluster. See Engine
Coolant Temperature Warning Light on page 4‑51 and
Engine Coolant Temperature Gauge on page 4‑51.
The vehicle may also display a ENGINE OVERHEATED
IDLE ENGINE message or an ENGINE OVERHEATED
STOP ENGINE message displayed in the Driver
Information Center (DIC). See DIC Warnings and
Messages on page 4‑62 for more information.
You will also hear a chime.
The decision may be made not to lift the hood when this
warning appears, but instead get service help right
away. See Roadside Service on page 8‑6.
If the decision is made 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 6‑31 for information on
driving to a safe place in an emergency.
