Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the surge tank,but only when the
engine is cool.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, press down and turn
it clockwise (right) until you hear a clicking sound.
Make sure you fully install the cap.
Coolant Surge Tank Pressure Cap
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.
SeeEngine Compartment Overview on page 6-12for
information on location.
Engine Overheating
You will nd a COOLANT OVER TEMP message or an
ENGINE HOT, STOP ENGINE message displayed in the
Driver Information Center (DIC). SeeDIC Warnings and
Messages on page 3-64. You will also hear a chime.
There is also an engine coolant temperature gage on the
instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-54.

If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the climate controls to the highest heat setting
and fan speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning does not come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for three
minutes while you are parked. If you still have the
warning,turn off the engine and get everyone out of the
vehicleuntil it cools down. Also, see “Overheated
Engine Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get service
help right away.Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency situation. If an overheated
engine condition exists and the DIC message ENGINE
HOT, STOP ENGINE is displayed, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi cant loss in power and engine
performance. Driving extended miles (km) in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. SeeEngine Oil on page 6-13.
