Warning (Continued)
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 betoo 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),andlettheengine idle.
If the engine coolant temperaturegauge is no longer in the overheatzone, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safedistance from the vehicle in front.If the warning does not come backon, continue to drive normally andhave the cooling system checkedfor 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.
Engine Fan
If the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.
This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.
If the vehicle has electric coolingfan(s), the fans may be heardspinning at low speed during most

everyday driving. The fans may turnoff if no cooling is required. Underheavy vehicle loading, trailer towing,high outside temperatures,or operation of the air conditioningsystem, the fans may change tohigh speed and an increase in fannoise may be heard. This is normaland indicates that the coolingsystem is functioning properly. Thefans will change to low speed whenadditional cooling is no longerrequired.
