DIC Compass
Your vehicle may have a compass in the Driver
Information Center (DIC).
Compass Zone
Under certain circumstances, such as during a
long distance cross-country trip, it will be
necessary to compensate for compass variance
and reset the zone through the DIC.
Compass variance is the difference between the
earth’s magnetic north and true geographic
north. If not adjusted to account for compass
variance, the compass in the vehicle could give
false readings.
In order to do this, the compass must be set or
calibrated to the variance zone in which the vehicle
is traveling.

and compressed audio les, but no folders, all les
are located under the root folder. The folder down
and the folder up buttons searches playlists (Px)
rst and then goes to the root folder. When the
radio displays the name of the folder the radio
displays ROOT.
Order of Play
Tracks recorded to the CD-R or CD-RW are
played in the following order:
Play begins from the rst track in the rst
playlist and continues sequentially through
all tracks in each playlist. When the last track
of the last playlist has played, play continues
from the rst track of the rst playlist.
Play begins from the rst track in the rst
folder and continues sequentially through
all tracks in each folder. When the last track of
the last folder has played, play continues

Overheated Engine Protection
Operating Mode
This emergency operating mode allows your
vehicle to be driven to a safe place in an
emergency situation. If an overheated engine
condition exists, an overheat protection mode
which alternates ring groups of cylinders helps
prevent engine damage. In this mode, you
will notice a signicant loss in power and engine
performance. The coolant temperature gage
will indicate an overheat condition exists. Driving
extended miles (km) and/or 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 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 310.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Coolant Recovery Tank
B. Pressure Cap
C. Electric Engine Cooling Fans
3.5L V6 Engine shown, 3.9L Engine similar
326

When the engine is cold, the coolant level should
be at or above the cold ll line on the coolant
recovery tank. To check the coolant level, look
for the cold ll line on the side of the coolant
recovery tank that faces the engine. If the level is
not correct, there may be a leak at the pressure
cap or in the radiator hoses, heater hoses,
radiator, water pump, or somewhere else in
the cooling system.
{CAUTION:
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 re,
and you could be burned. Get any leak
xed before you drive the vehicle.If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fans
are running. If the engine is overheating, the fans
should be running. If the fans are not running,
your vehicle needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty. SeeOverheated Engine Protection
Operating Mode on page 326for information on
driving to a safe place in an emergency.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
