Engine Coolant
The cooling system in the vehicle isfilled with DEX-COOL enginecoolant. This coolant is designed toremain in the vehicle for 5 years or240 000 km (150,000 mi), whicheveroccurs first.
The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,seeEngine Overheating0230.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The 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 cleandrinkable water and DEX-COOLcoolant. This mixture:
.Gives freezing protection downto✓37 °C (✓34 °F), outsidetemperature.
.Gives boiling protection up to129 °C (265 °F), enginetemperature.
.Protects against rust andcorrosion.
.Will not damage aluminum parts.
.Helps keep the proper enginetemperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants0300.
Never dispose of engine coolant byputting it in the trash, pouring it onthe ground, or into sewers, streams,or bodies of water. Have the coolantchanged by an authorized servicecenter, familiar with legalrequirements regarding usedcoolant disposal. This will helpprotect the environment and yourhealth.

228 Vehicle Care
Checking Coolant
The vehicle must be on a levelsurface when checking the coolantlevel.
It is normal to see coolant moving inthe upper coolant hose return linewhen the engine is running.
Check to see if coolant is visible inthe coolant surge tank. If the coolantinside the coolant surge tank isboiling, do not do anything else untilit cools down.
If coolant is visible but the coolantlevel is not at or above the markpointed to, add a 50/50 mixture ofclean drinkable water andDEX-COOL coolant.
Be sure the cooling system is coolbefore this is done.
If no coolant is visible in the coolantsurge tank, add coolant as follows:
How to Add Coolant to the
Coolant Surge Tank
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
If no problem is found, check to seeif coolant is visible in the coolantsurge tank. If coolant is visible butthe coolant level is not at theindicated level mark, add a 50/50 mixture of clean, drinkable waterand DEX-COOL coolant at thecoolant surge tank, but be sure thecooling system, including thecoolant surge tank pressure cap, iscool before you do it.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn

the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.

230 Vehicle Care
By this time, the coolant levelinside the coolant surge tankmay be lower. If the level islower, add more of the properDEX-COOL coolant mixture tothe coolant surge tank until thelevel reaches the indicatedlevel mark.
5. Replace the pressure captightly.
Check the level in the coolant surgetank when the cooling system hascooled down. If the coolant is not atthe proper level, repeat Steps 1–3andreinstallthepressurecap.If the coolant still is not at the properlevel when the system cools downagain, see your dealer.
Caution
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 an indicator to warnof the engine overheating.
If the decision is made not to lift thehood when this warning appears,get service help right away. SeeRoadside AssistanceProgram0311.
If the decision is made to lift thehood, make sure the vehicle isparked on a level surface.
Then check to see if the enginecooling fan is running. If the engineis overheating, the fan should berunning. If it is not, do not continueto run the engine. Have the vehicleserviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam Is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not be

too serious. Sometimes the enginecan get a little too hot when thevehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayedwith no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral) for an automatictransmission or Neutral for amanual transmission, and letthe engine idle.
If the overheat warning no longerdisplays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not come
back on, continue to drive normallyand have the cooling systemchecked for proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is no sign of steam, idle theengine for three minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.
Washer Fluid
What to Use
When the vehicle needs windshieldwasher fluid, be sure to read themanufacturer's instructions beforeuse. If operating the vehicle in anarea where the temperature may fallbelow freezing, use a fluid that hassufficient protection againstfreezing.
Adding Washer Fluid
Open the cap with the washersymbol on it. Add washer fluid untilthe tank is full. SeeEngineCompartment Overview0217forreservoir location.
Caution
.Do not use washer fluid thatcontains any type of waterrepellent coating. This cancause the wiper blades tochatter or skip.
.Do not use engine coolant(antifreeze) in thewindshield washer. It candamage the windshieldwasher system and paint.
