{WARNING:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
Notice:Using coolant other than DEX-COOL®cancause premature engine, heater core, or radiatorcorrosion. In addition, the engine coolant couldrequire changing sooner, at 50 000 km (30,000 miles)or 24 months, whichever occurs first. Any repairswould not be covered by the vehicle warranty.Always use DEX-COOL®(silicate-free) coolantin the vehicle.
Engine Coolant
The cooling system in the vehicle is filled withDEX-COOL®engine coolant. This coolant is designedto remain in the vehicle for five years or 150,000 miles(240 000 km), whichever occurs first.
The following explains the cooling system and how tocheck and add coolant when it is low. If there is aproblem with engine overheating, seeEngineOverheating on page 7!34.

What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper
coolant mixture will. The vehicle's coolant warning
system is set for the proper coolant mixture. With
plain water or the wrong mixture, the engine could
get too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL®coolant.
Use a 50/50 mixture of clean, drinkable water andDEX-COOL®coolant. If using this mixture, nothingelse needs to be added. This mixture:
.Gives freezing protection down to!34°F (!37°C),outside temperature.
.Gives boiling protection up to 265°F (129°C),engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used, theengine could overheat and be badly damaged. Therepair cost would not be covered by the vehiclewarranty. Too much water in the mixture can freezeand crack the engine, radiator, heater core, andother parts.
Notice:If extra inhibitors and/or additives are usedin the vehicle's cooling system, the vehicle could bedamaged. Use only the proper mixture of the enginecoolant listed in this manual for the cooling system.SeeRecommended Fluids and Lubricantsonpage 8!10for more information.

If No Steam Is Coming From The
Engine Compartment
The ENGINE OVERHEATED STOP ENGINE or theENGINE OVERHEATED IDLE ENGINE message, alongwith a low coolant condition, can indicate a seriousproblem.
If you get an engine overheat warning, but see or hearno steam, the problem may not be too serious.Sometimes the engine can get a little too hot when you:
.Climb a long hill on a hot day.
.Stop after high-speed driving.
.Idle for long periods in traffic.
.Tow a trailer. SeeTowing a Trailer on page 6!42.
If you get the ENGINE OVERHEATED STOP ENGINEor the ENGINE OVERHEATED IDLE ENGINE messagewith no sign of steam, try this for a minute or so:
If the overheat warning is displayed with no sign ofsteam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature andto the highest fan speed. Open the windows asnecessary.
3. In heavy traffic, let the engine idle in N (Neutral)while stopped. If it is safe to do so, pull off theroad, shift to P (Park) or N (Neutral) and let theengine idle.
If the temperature overheat gage is no longer in theoverheat zone or an overheat warning no longerdisplays, the vehicle can be driven. Continue to drivethe vehicle slow for about 10 minutes. Keep a safevehicle distance from the car in front of you. If thewarning does not come back on, continue to drivenormally.
If the warning continues, pull over, stop, and park thevehicle right away.
If there is no sign of steam, idle the engine forfive minutes while parked. If the warning is stilldisplayed, turn off the engine until it cools down. Also,see“Overheated Engine Protection Operating Mode”later in this section.
