When the Light Flashes First and Then is
On Steady This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes for about
a minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. See Tire Pressure Monitor System on page 6-64
for more information.
Malfunction Indicator Lamp
Check Engine Light A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer. If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice: If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice: Modications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3 .

DIC Operation and Displays The DIC has different displays which can be accessed
by pressing the DIC buttons located on the instrument
panel, next to the steering wheel.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. A digital speedometer also appears at the
bottom of the DIC display. The digital speedometer can
be enabled or disabled. See “DISPLAY DIGITAL SPEED”
under DIC Vehicle Customization on page 3-65 for more
information.
DIC Buttons The buttons are
the trip/fuel, vehicle
information, customization,
and set/reset buttons.
The button functions are
detailed in the following
pages. 3 (Trip/Fuel): Press this button to display
the odometer, trip odometer, fuel range, average
economy, fuel used, timer, and transmission temperature.
The compass and outside air temperature will also be
shown in the display. The temperature will be shown
in °F or °C depending on the units selected.
T (Vehicle Information): Press this button to display
the oil life, units, side blind zone system on/off, tire
pressure readings for vehicles with the Tire Pressure
Monitor System (TPMS), Remote Keyless Entry (RKE)
transmitter programming, compass zone setting, and
compass recalibration.
U (Customization): Press this button to customize
the feature settings on your vehicle. See DIC Vehicle
Customization on page 3-65 for more information.
V (Set/Reset): Press this button to set or reset certain
functions and to turn off or acknowledge messages
on the DIC.

Before Leaving on a Long Trip To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid: Reservoir full? Windows
clean — inside and outside?
Wiper Blades: In good shape?
Fuel, Engine Oil, Other Fluids: All levels checked?
Lamps: Do they all work and are lenses clean?
Tires: Are treads good? Are tires inated to
recommended pressure?
Weather and Maps: Safe to travel? Have
up-to-date maps? Highway Hypnosis Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle instruments
often.

Certication/Tire Label
A vehicle specic Certication/Tire label is attached
to the rear edge of the driver’s door. The label
shows the size of your vehicle’s original tires and
the ination pressures needed to obtain the gross
weight capacity of your vehicle. This is called Gross
Vehicle Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all occupants,
fuel, and cargo.
The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR). To nd 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 center line.
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.
{ CAUTION: Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.
Your warranty does not cover parts or components
that fail because of overloading.
The label will help you decide how much cargo
and installed equipment your truck can carry.

Engine Oil
Checking Engine Oil It is a good idea to check the engine oil level at each
fuel ll. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
See Engine Compartment Overview on page 6-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Tire Terminology and Denitions Air Pressure :
The amount of air inside the
tire pressing outward on each square inch of the
tire. Air pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight :
This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio :
The relationship of a tire’s height
to its width.
Belt :
A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead :
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire :
A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread. Cold Tire Pressure :
The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. See Inflation - Tire Pressure on
page 6-62 .
Curb Weight :
The weight of a motor vehicle with
standard and optional equipment including the
maximum capacity of fuel, oil, and coolant, but
without passengers and cargo.
DOT Markings :
A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identication Number (TIN),
an alphanumeric designator which can also identify
the tire manufacturer, production plant, brand,
and date of production.
GVWR :
Gross Vehicle Weight Rating.
See Loading the Vehicle on page 5-33 .
GAWR FRT :
Gross Axle Weight Rating for the
front axle. See Loading the Vehicle on page 5-33 .
