Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.
That's normal. If the light doesn't come on then, have it
®xed so it will be ready to warn you if there is a
problem.
If the light stays on, or comes on when you're driving,
your vehicle needs service. You will also hear a
chime sound when the light is on steady. If the regular
brake system warning light isn't on, you still have
brakes, but you don't have anti-lock brakes. If the
regular brake system warning light is also on you don't
have anti-lock brakes and there's a problem with
your regular brakes. In addition to both lights, you will
also hear a chime sound on the ®rst occurrence of
a problem and each time the vehicle is shut off and then
restarted. See
Brake System Warning Light on
page 3-37.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210ÉF (100ÉC) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
¯uctuate and approach the 250ÉF (122ÉC) mark. If the
gage reaches the 260ÉF (125ÉC) mark, it indicates
that the cooling system is working beyond its capacity.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-6.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see ªRecreational Vehicle Towingº following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle Ð such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as ªdinghy towingº (towing your
vehicle with all four wheels on the ground) and ªdolly
towingº (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a ªdollyº).
Your vehicle was not designed to be towed with any of
its wheels on the ground. If your vehicle must be
towed, see
Towing Your Vehicle on page 4-48.
Notice:Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle if
any of its wheels will be on the ground.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all occupants,
cargo and all nonfactory-installed options. Two labels
on your vehicle show how much weight it may properly
carry, the Tire and Loading Information label and the
Certi®cation/Tire label.
{CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your 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 your vehicle.

Tire and Loading Information Label
A. Vehicle Capacity WeightThe Tire and Loading Information label is attached to
the center pillar, near the driver's door latch. Vehicles
without a center pillar will have the Tire and Loading
Information label attached to the driver's door edge. This
label lists the number of people that can be in your
vehicle and the total weight it can carry. This weight is
called the vehicle capacity weight.
The Tire and Loading Information label also tells you
the size and recommended in¯ation pressure for
the original equipment tires on your vehicle. For more
information on tires and in¯ation see
Tires on page 5-59andIn¯ation - Tire Pressure on page 5-67
If your vehicle does not have the Tire and Loading
Information label, the Certi®cation/Tire label shows the
tire size and recommended in¯ation pressures
needed to obtain the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axles. See
ªCerti®cation/Tire Labelº later in this section.

Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of
occupants and cargo should never exceed
XXX poundsº on your vehicle placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds.
4. The resulting ®gure equals the available amount
of cargo and luggage load capacity. For example,
if the ªXXXº amount equals 1400 lbs. and there
will be ®ve 150 lb. passengers in your vehicle,
the amount of available cargo and luggage load
capacity is 650 lbs. (1400-750
(5 x 150) = 650 lbs.).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, the load from
your trailer will be transferred to your vehicle.
Consult this manual to determine how this reduces
the available cargo and luggage load capacity of
your vehicle.
See
Towing a Trailer on page 4-58for more
information on towing a trailer, towing safety rules
and trailering tips.

Certi®cation/Tire Label
The Certi®cation/Tire label is found on the rear edge of
the driver's door.
The label shows the size of your original tires and the
in¯ation 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 Certi®cation/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 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.
{CAUTION:
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.

Payload
Payload capacity is the maximum load capacity that
your vehicle can carry. Be sure to include the weight of
the occupants as part of your load. If you added any
accessories or equipment after your vehicle left
the factory, remember to subtract the weight of these
things from the payload. Your dealer can help you
with this.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
Two-Tiered Loading
By positioning four 2º x 6º wooden planks across the
width of the pickup box, you can create an upper
load platform. The planks must be inserted in the pickup
box depressions. The length of the planks must allow
for at least a 3/4 inch (2 cm) bearing surface on
each end of the plank.
When using this upper load platform, be sure the load is
securely tied down to prevent it from shifting. The
load's center of gravity should be positioned in a zone
over the rear axle. The zone is located in the area
between the front of each wheel well and the rear of
each wheel well. The center of gravity height must not
extend above the top of the pickup box ¯areboard.Any load that extends beyond the vehicle's taillamp
area must be properly marked according to local laws
and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
*Equipment Maximum Weight
Ladder Rack and Cargo 750 lbs. (340 kg)
Cross Toolbox and Cargo 400 lbs. (181 kg)
Side Boxes and Cargo 250 lbs. per side
(113 kg per side)
*The combined weight for all rail-mounted equipment
should not exceed 1,000 lbs. (454 kg). A
reinforcement kit for rail-mounted add-on equipment is
recommended. See your dealer.

Weight of Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will
also reduce the trailer weight your vehicle can tow. And
if you will tow a trailer, you must add the tongue load
to the GVW because your vehicle will be carrying
that weight, too. See
Loading Your Vehicle on page 4-48for more information about your vehicle's maximum
load capacity.
The trailer tongue weight (A) should be 10 percent to
15 percent of the total loaded trailer weight, up to
a maximum or 600 (272 kg) for the 1500 series with a
weight carrying hitch. The trailer tongue weight (A)
should be 10 percent to 15 percent of the total loaded
trailer weight, up to a maximum of 1,000 (453 kg) for the
1500 series with a weight distributing hitch.
Fifth wheel or gooseneck kingpin weight should be 15 to
25 percent of the trailer weight up to the maximum
amount speci®ed in the trailering chart for your vehicle.
See ªWeight of theTrailerº in this section.
