Vehicle Loading; Certification Label - Jeep GLADIATOR 2022 Owner's Manual

CAUTION!
•
To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not "top off" the DEF
tank after filling.
•
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the sys-
tem could be damaged.
•
When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.
•
Do not attempt to start your engine if DEF is acciden-
tally added to the diesel fuel tank as it can result in
severe damage to your engine, including but not lim-
ited to failure of the fuel pump and injectors.
•
Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel
fuel, fuel system additives, gasoline, or any other
petroleum-based product. Even a very small
amount of these, less than 100 parts per million or
less than 1 oz. per 78 gallons (295 liters) will con-
taminate the entire DEF system and will require
replacement. If owners use a container, funnel or
nozzle when refilling the tank, it should either be
new or one that has only been used for adding
DEF. Mopar® provides an attachable nozzle with
its DEF for this purpose.
3. Stop filling the DEF tank immediately when any of
the following happen: DEF stops flowing from the fill
bottle into the DEF fill inlet, DEF splashes out the fill
inlet, or a DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF fill inlet.

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), front and rear
Gross Axle Weight Rating (GAWR), and Vehicle Identifi-
cation 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 Gross Axle Weight Rating (GAWR). Total load
must be limited so GVWR on 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.
STARTING AND OPERATING
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 repre-
sents 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.
