The six-disc CD changer has a feature called
song list. This feature is capable of saving 20 track
selections.
To save tracks into the song list feature, perform
the following steps:
1. Turn the CD player on and load it with at least
one CD. See “LOAD CD” listed previously in
this section for more information.
2. Check to see that the CD changer is not in
song list mode. S-LIST should not appear on
the display. If S-LIST is present, press the
SONG LIST button to turn it off.
3. Select the desired CD by pressing the
numbered pushbutton and then use the SEEK
or TYPE right arrow to locate the track to
be saved. The track begins to play.
4. Press and hold the SONG LIST button to
save the track into memory. When SONG
LIST is pressed, one beep will sound.
After two seconds of continuously pressing
the SONG LIST button, two beeps will sound
to confirm the track has been saved.
5. Repeat Steps 3 and 4 for saving other
selections.

S-LIST FULL appears on the display if you try to
save more than 20 selections.
To play the song list, press the SONG LIST
button. One beep will sound and S-LIST appears
on the display. The recorded tracks begins to
play in the order they were saved.
Seek through the song list by using the SEEK or
TYPE arrows. Seeking past the last saved
track returns to the first saved track.
To delete tracks from the song list, perform the
following steps:
1. Turn the CD player on.
2. Press the SONG LIST button to turn song list
on. S-LIST appears on the display.
3. Press either SEEK or TYPE arrow to select

Tow/Haul Mode
Tow/haul is designed to assist while your vehicle
is pulling a large or heavy load or trailer.
Tow/haul is most useful while pulling such a load
in rolling terrain, in stop-and-go traffic, or when
you need improved low-speed control, such
as when parking. The purpose of the tow/haul
mode is to:
•Reduce the frequency and improve the
predictability of transmission shifts,
•provide the same solid shift feel when pulling
a heavy load as when the vehicle is unloaded,
•improve control of vehicle speed while
requiring less throttle pedal activity.
Press this button
located to the right of
the steering wheel
on the instrument panel
to turn tow/haul
mode on and off.While activated, the
indicator light on the
instrument panel
will be on.
Tow/haul mode will turn off automatically when the
ignition is turned off. SeeTow/Haul Mode Light
on page 185.
Tow/haul is most effective when the vehicle and
trailer combined weight is at least 75 percent of the
vehicle’s Gross Combined Weight Rating
(GCWR). See “Weight of the Trailer” later in this
section.
Driving with tow/haul activated without a heavy
load will cause reduced fuel economy and
unpleasant engine and transmission driving
characteristics, but will not cause damage.

Checking Coolant for Gasoline Engines
If your vehicle has a diesel engine, see “Checking
Coolant” under “Van Models” in the DURAMAX®
Diesel Supplement for information on checking
your vehicle’s coolant.
The coolant recovery
tank is located near the
center of the engine
compartment. See
Engine Compartment
Overview on page 296
for more information
on location.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be at
the COLD FILL mark, or a little higher.
Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the coolant
recovery tank, but be careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. With the coolant
recovery tank, you will almost never
have to add coolant at the radiator. Never
turn the radiator pressure cap — even
a little — when the engine and radiator
are hot.
308

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, and you have not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, push down the
accelerator until the engine speed is about
twice as fast as normal idle speed for at least
three minutes while you are parked. 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.Cooling System
If your vehicle has a diesel engine, see “Van
Models” under “Cooling System” in the
DURAMAX
®Diesel Supplement.
When you decide it is safe to lift the hood, here is
what you will see:
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Cooling Fan(s)
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
311

When the engine is cold, the coolant level should
be at or above the COLD FILL mark. If it is not, you
may have 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, fuel operated heater (FOH),
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, start the engine
again. See if the engine cooling fan speed
increases when idle speed is doubled by pushing
the accelerator pedal down. If it does not, your
vehicle needs service. Turn off the engine.Notice:Engine damage from running your
engine without coolant is not covered by
your warranty.
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.
How to Add Coolant to the Coolant
Recovery Tank for Gasoline Engines
If your vehicle has a diesel engine, see “How
to Add Coolant to the Coolant Recovery Tank”
under “Van Models” in the Cooling System section
of the DURAMAX
®Diesel Supplement for the
proper coolant fill procedure.
If you have not found a problem yet, but the
coolant level is not at the COLD FILL mark, add a
50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant at the coolant
recovery tank. SeeEngine Coolant on page 306
for more information.
312

{CAUTION:
You can be burned if you spill coolant
on hot components in the engine
compartment. Coolant contains ethylene
glycol, and it will burn if the engine parts
are hot enough. Do not spill coolant on a
hot engine or components in the engine
compartment.
When the coolant in the coolant recovery tank is
at the COLD FILL mark, start your vehicle.
If the overheat warning continues, there is
one more thing you can try. You can add the
proper coolant mixture directly to the radiator,
but be sure the cooling system is cool before
you do it.
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn you
badly. They are under pressure, and if you
turn the radiator pressure cap — even a
little — they can come out at high speed.
Never turn the cap when the cooling
system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever
have to turn the pressure cap.
How to Add Coolant to the Radiator for
Gasoline Engines
If your vehicle has a diesel engine, see “How to
Add Coolant to the Radiator” under “Van Models”
in the Cooling System section of the DURAMAX
®
Diesel Supplement for the proper radiator fill
procedure.
