GETTING TO KNOW YOUR INSTRUMENT PANEL113
 The fuel pump symbol points
to the side of the vehicle where
the fuel filler door is located.
Refer to “Refueling The Vehicle — Gas
Engine” in “Starting And Operating” for
further information.
5. Diesel Exhaust Fluid (DEF) Gauge
The DEF Gauge displays the actual level
of Diesel Exhaust Fluid in the DEF tank.
Diesel Exhaust Fluid (DEF) is required to
maintain normal vehicle operation and
emissions compliance. If something is
wrong with the gauge, a DEF Warning
Message or Malfunction Indicator Light
(MIL) will be displayed. More information
is available in the instrument cluster
display section under the heading of
Diesel Exhaust Fluid (DEF) Warning
Messages. NOTE:

The DEF tank on these vehicles is designed
with a large amount of full reserve. So the level
sensor will indicate a full reading even before
the tank is completely full. To put it another
way, there’s additional storage capacity in the
tank above the Full mark that’s not repre
-
sented in the gauge. You may not see any
movement in the reading – even after driving
up to 200 miles (322 kilometers) in some
cases.

The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid (DEF) to the DEF tank. If
you have a fault related to the DEF system,
the gauge may not update to the new level.
See an authorized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 39°F (4°C). The DEF tank
heater will warm up the DEF fluid and allow
the gauge to update after a period of run
time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill
level for several drives.
INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an
instrument cluster display, which offers useful
information to the driver. With the ignition in the
OFF mode, opening/closing of a door will
activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your
instrument cluster display is designed to display
important information about your vehicle’s
systems and features. Using a driver interactive
display located on the instrument panel, your
instrument cluster display can show you how
systems are working and give you warnings
when they are not. The steering wheel mounted
controls allow you to scroll through the main
menus and submenus. You can access the
specific information you want and make
selections and adjustments.

system to operate properly at temperatures
below 12°F (-11°C). If your vehicle is not in
operation for an extended period of time with
temperatures below 12°F (-11°C), the DEF in
the tank may freeze. If the tank is overfilled and
freezes, it could be damaged. Therefore, do not
overfill the DEF tank.
Extra care should be taken when filling with
portable containers to avoid overfilling. Note the
level of the DEF gauge in your instrument
cluster. You may safely add a maximum of
2 Gallons (7.5 Liters) of DEF from portable
containers when your DEF gauge is reading
½ full.
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 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
increased durability does 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
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.
