straps frequently to be sure that the load remains securely
attached.
The roof rack does not increase the total load carrying
capacity of the vehicle. Be sure the total load of cargo inside
the vehicle plus that on the external rack does not exceed
the maximum vehicle load capacity.Deploying The Crossbars
1. To deploy the crossbars, completely loosen the thumbscrews at both ends of the crossbar and lift the crossbar
from its stowed position in the side rail. Repeat with
crossbar on the opposite side.
NOTE: The thumb screws cannot be fully removed.

6. Repeat the procedure to stow the second crossbar on theopposite side.
NOTE:
• To help control wind noise, stow the crossbars in the side
rails when they are not in use.
• If any metallic object is placed over the satellite radio
antenna (if equipped), you may experience interruption
of satellite radio reception.WARNING!
Cargo must be securely tied down before driving your
vehicle. Improperly secured loads can fly off the ve-
hicle, particularly at high speeds, resulting in personal
injury or property damage. Follow the roof rack cau-
tions when carrying cargo on your roof rack.
CAUTION!
• To prevent damage to the roof of your vehicle, DO
NOT carry any loads on the roof rack without the
crossbars deployed. The load should be secured and
placed on top of the crossbars, not directly on the
roof. If it is necessary to place the load on the roof,
place a blanket or other protective layer between the
load and the roof surface.
• To avoid damage to the roof rack and vehicle, do not
exceed the maximum roof rack load capacity of 150 lb
(68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
• Load should always be secured to cross bars first,
with tie down loops used as additional securing

VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo. The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires must
be equal to the load capacity of this tire size.
424 STARTING AND OPERATING
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then bedetermined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
weight limitations are met. Store the heavier items down
low and be sure that the weight is distributed equally. Stow
all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do, parts
on your vehicle can break, or it can change the way
your vehicle handles. This could cause you to lose
control. Also overloading can shorten the life of your
vehicle.

TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with
your vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue weight.
The total load must be limited so that you do not exceed
the GVWR. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in itsloaded and ready for
operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight of
the trailer must be supported by the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
426 STARTING AND OPERATING
Vehicle Loading Chart
Follow these steps to determine the total weight the vehicle
can carry.
1. Determine the cargo capacity of your vehicle.•Load Capacity = GVWR – Curb (weight of vehicle full
fluids NO Occupants).
2. Determine occupant count. •For calculation purposes, average weight of an occu-
pant is 150 lb (68 kg).
EXAMPLE: •
GVWR = 6005 lbs (2723 kg)
• CURB = 4500 lbs (2041 kg)
• Load Capacity = GVWR – CURB = 6005 lbs (2723 kg) -
4500 lbs (2041 kg) = 1505 lbs (682 kg)
4 Occupants (at 150 lbs [68 kg]) + Max Trailer =
• 1505 lbs (682 kg) – 600 lbs (272 kg) (4 x 150 lbs [68 kg])
– 360 lbs (163 kg) (10% of 3600 lbs [1632 kg]) = 545 lbs
(247 kg) of cargo in vehicle

430 STARTING AND OPERATING
•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
•
When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will not
increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required. •
Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping dis-
tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
