198 STARTING AND OPERATING
(Continued)
Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
DEF tank.
If systems which cannot be screwed in (e.g.
tanks) are used for refilling, after the indica-
tion appears on the instrument panel
display Ú page 117 fill the DEF tank with no
more than 2 gallons (8 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when the
DEF level in the container stops pouring out.
Do not proceed further.
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
Administration 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.
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,
however, if the tank is overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi-
ately with water and use an absorbent mate-
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited 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 contami-
nate 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.
CAUTION!
