Tow/Haul Mode Light
This light should come on
when the tow/haul mode
has been selected.
For more information, see “Tow/Haul Mode” inTowing
a Trailer on page 4-35.
Check Gages Warning Light
The CHECK GAGES
light will come on briey
when you are starting
the engine.
If the light comes on and stays on while you are driving,
check your coolant temperature and engine oil pressure
gages to see if they are in the warning zones.
Fuel Gage
The fuel gage tells you approximately how much fuel
you have remaining when the ignition is on.
When the gage rst indicates empty, you still have a
little fuel left, but you should get more fuel as soon
as possible.

Here are things some owners ask about. None of these
indicate a problem with your fuel gage:
At the gas station, the gas pump shuts off before
the gage reads full.
The fuel tank will take either a little more or a little
less fuel to ll up than the gage shows.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to empty when you turn
off the ignition.
Low Fuel Warning Light
The LOW FUEL light
will come on briey
when you are starting
the engine.
This light comes on when the fuel tank is low
on fuel. To turn it off, add fuel to the fuel tank.
SeeFuel on page 5-4.
Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See
“Retained Accessory Power (RAP)” underIgnition
Positions on page 2-18.

track number will appear on the display.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in nding tracks, and/or difficulty in
loading and ejecting. If these problems occur try a
known good CD.
Do not add paper labels to CDs, they could get caught
in the CD player.If an error appears on the display, see “CD Messages”
later in this section.

If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time
and you must start the procedure over at Step 4.

{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your
engine and transmission, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at
speeds that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car
or an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area or winding roads. Be alert to these and take
appropriate action.
4-23

Then, during the rst 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
See also “Driving on Grades” later in this section.
Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
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, and
improve control of vehicle speed while requiring
less throttle pedal activity.Press the button on the end of the shift lever 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 3-34.
Tow/haul is most effective when the vehicle and trailer
combined weight is at least 75% 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.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig.
For example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to
pull a trailer are all important. And, it can also
depend on any special equipment that you have
on your vehicle.
