172STARTING AND OPERATING
VEHICLE LOADING
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 Gross Axle Weight Rating (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
increased durability, do not necessarily increase the
vehicle'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.
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 Gross Axle Weight Rating
(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 ensure that the Gross Vehicle Weight Rating
(GVWR) has not been exceeded. The weight on the front
and rear of the vehicle should then be determined
separately to be sure that the load is properly distributed
over the front and rear axle. Weighing the vehicle may
show that the Gross Axle Weight Rating (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.
WARNING!
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.
Overloading can shorten the life of your vehicle.

190STARTING AND OPERATING
OFF-ROAD DRIVING TIPS
Care should be taken when attempting to climb steep hills
or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously.
If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diagonally
across the hill.
When driving over sand, mud, and other soft terrain, shift
to low gear and drive steadily. Apply the accelerator slowly
to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required. 
Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
CAUTION!
Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
 Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
 Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
 Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, transmis -
sion, axle, etc.) for signs of contamination (i.e., fluid
that is milky or foamy in appearance) after driving
through standing water. Do not continue to operate
the vehicle if any fluid appears contaminated, as this
may result in further damage. Such damage is not
covered by the New Vehicle Limited Warranty.
 Getting water inside your vehicle’s engine can cause
it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered
by the New Vehicle Limited Warranty.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.

278SAFETY
NOTE:
The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure, unless your vehicle
is equipped with a Tire Fill Alert (TFA) system.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.

Tire Pressure Monitoring System Display

The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPMS consists of the following components:
 Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System (TPMS)
Warning Light will illuminate in the instrument
cluster and a chime will sound when tire
pressure is low in one or more of the four active
road tires. In addition, the instrument cluster will display a
graphic showing the pressure values of each tire with the
low tire pressure values in a different color. An "Inflate to
XX" message will also be displayed.

Low Tire Pressure Display

Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition
(those in a different color in the instrument cluster
graphic) to the vehicle’s recommended cold placard
pressure inflation value as shown in the "Inflate to XX"
message. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the instrument cluster will return to its
original color, and the Tire Pressure Monitoring System
Warning Light will turn off. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring System Warning Light off.

Fuel Funnel Location

NOTE:
In certain cold conditions, ice may prevent the fuel door
from opening. If this occurs, lightly push on the fuel door
to break the ice buildup and re-release the fuel door using
the inside release button. Do not pry on the door.
Emergency Gas Can Refueling:
Most gas cans will not open the flapper doors. A funnel is
provided to allow emergency refueling with a gas can.
See the following steps for refueling:

1. Retrieve funnel from under the passenger’s front seat.

2. Insert funnel into same filler pipe opening as the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present
CAUTION!
To avoid fuel spillage and overfilling, do not “top off” the
fuel tank after filling.
WARNING!
Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
Never add fuel when the engine is running. This is in
violation of most state and federal fire regulations
and may cause the Malfunction Indicator Light to
turn on.
 A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
WARNING!
