{Warning
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{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.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.

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
(Continued)
Warning (Continued)
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.

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.
