Should a low coolant condition exist and the stop “STOP ENGINE
ENGINE OVERHEATING” message is displayed, an overheat
protection mode which alternates firing groups
of four cylinders helps

to be
driven to a safe place in an emergency. You may drive up to 50 miles (80
km). Towing a trailer 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 befo\
re
attempting any repair.
The engine oil may be severely degraded. Change the oil and
reset the oil life indicator. (See “Engine Oil, When to Change”

If the warning doesn't come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right\

If there's still no sign of steam, you can idle the engine for two or three
minutes while you're parked, to see
if the warning stops. But then, if you
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.

If the coolant inside the coolant. surge tank is boiling, don’t do anything
else until it cools
down.
I
The coolant level should be visible inside the surge tank. If it isn’t and the
“ENGINE
COOLANT LOW” message appears on the Driver
Information Center, you may have a coolant leak somewhere in the
cooling system.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty. See “Overheated Engine Protection
Operating Mode” in the Index.
If there seems to be no leak, check to see if the electric engine fans are
running. If the engine is overheating, both fans should be running.
If they
aren’t, your vehicle needs service.
How to Add‘Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’tvisible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is
cool
before you do it. (See “Engine Coolant’’ in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator hose, heater hoses, radiator,
water pump or somewhere else in the cooling system.
c
NOTICE:
I
In cold weather, water can freeze and crack the engine, radiat\
or, -
heater core and other parts. So use the recommended coolant. L

cap and upper
radiator
hose, is

cap slowly to the
left until it first
stops.
If you hear a hiss, wait for that to stop. A hiss means there is still some
pressure left.
