If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
0 If towing a trailer, reduce the amount of cargo being
hauled
as soon as it is possible.
If the light stops flashing and remains
on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains
on steady, see “If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle
to your dealer or
qualified service center for service.
You may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel
into your vehicle?
If so7 reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. This will
allow fuel to evaporate into
the atmosphere. A few
driving trips should turn the light off.
Did
you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will
usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make
sure to install the fuel cap properly. it
will take a few driving trips to turn the light off.

Fuel Gage
81 The fuel gage, when the
ignition is on, tells you
about how much fuel you
have left
in your tank.
E
The gage will first indicate EMPTY (E) before you
are
out of fuel, and you should get more fuel as soon
as possible. Here
are four situations
you may experience with your
fuel gage. None of these indicate a problem with the
fuel gage.
At the gas station, the fuel pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the
fuel gage indicated.
For example, the gage may have
indicated the tank was half full, but
it actually took a
little more or less than half the tank’s capacity to fill
the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to EMPTY (E) when you
turn off the ignition.
If you have a diesel engine, see “Fuel Gage”
in the
Diesel Engine Supplement.

Temperature Knob
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger
area of your vehicle. This knob will allow you to adjust
the relative air temperature independently
of the
function knob setting. Move the knob clockwise
toward
the red area for warmer air. Move the knob
counterclockwise toward the blue area for cooler air.
The right knob on the control panel allows you to
choose the direction of air delivery. The control knob
can be placed
in any position between two mode settings
to blend the flow of air.
/J VENT: This setting directs air through the
instrument panel outlets.
+H VENT/HEAT Use this setting to divide airflow
between the floor outlets and instrument panel outlets.
+’ HEATER: This setting directs air through the
heater floor outlets.
+e
+.
0
Qe
+’ DEFOG: This setting directs air to the heater
outlets and toward
the windshield.
DEFROST This setting directs air toward the
windshield.
Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for
the air conditioner to work it’s best.
The recirculation button, between the fan and
temperature knobs, allows the air inside your vehicle to
be recirculated. This setting helps
to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also
cools the air the fastest and
can be used
to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner,
turn off recirculation after the vehicle reaches a
comfortable interior temperature. When the right knob
on the control panel is between HEATER and
DEFROST, the recirculation feature will
not function.

Loading Your Vehicle
n ", ,. , I --- SEE OWNER'S MANUAL FOR ADDITIONAL INFORMATION I U
The Certificatiomire label is found on the rear edge of
the driver's door or in the Incomplete Vehicle Document
in the cab.
The label shows the size of your original tires and the
inflation pressures needed to obtain the gross weight
capacity
of your vehicle. This is called the GVWR
(Gross Vehicle Weight Rating).
The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
The Certificationmire label also tells
you the maximum
weights for the front and rear axles, called Gross
Axle
Weight Rating (GAWR). To find out the actual loads on your
front and rear axles,
you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And,
if you do have a heavy load, you should spread
it
out.
I
In the case of a sudden stop or collision, things
carried in the bed
of your truck could shift
forward and come into the passenger area,
injuring you and others.
If you put things in the
bed
of your truck, you should make sure they are
properly secured.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your dealer to help you load your vehicle the right way.

Fuels in Fo ign Countries -- Gasoline
Engines
If you plan on driving in another country outside the
United States or Canada, the proper
fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended
in the previous text on fuel. Costly repairs
caused by use
of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.

Filling Your Tank
The fuel cap is behind a
hinged door on the left side
of your vehicle.
On a chassis-cab model, refuel the front
tank first, or in
instances when only a partial fuel fill is desired.

Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials
away from gasoline.
While refueling,
hang the
cap inside the fuel door.
To take off the. cap, turn it slowly to the left
(counterclockwise).
/i CAUTIP
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on
you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap
all the way.

Be careful not to spill gasoline. Clean gasoline from
painted surfxes as soon
as possible. See “Cleaning the
Outside
of Your Vehicle” in the Index.
When you put the cap back
on, turn it to the right until
you hear at least three clicks. Make sure you fully install
the cap. The diagnostic system can determine if the fuel
cap has been
left off or improperly installed. This would
allow
fuel to evaporate into the atmosphere. See
“Malfunction Indicator Lamp” in the Index.
I NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you. If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under the Hood
h
I ! CAUTION:
If your vehicle has air conditioning, the auxiliary
engine fan under the hood can start up and
hjure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline or
diesel fuel, oil, coolant, brake fluid, windshield
washer and other fluids, and plastic or rubber.
You
or others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
