Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired will
result in the following actions as required
by the California Air Resources Board
(CARB) and U.S. Environmental Protection
Agency (EPA):
•
Within a certain number of miles
(kilometers) to empty, speed will be
limited upon restart. Prior to this
occurring a message will appear in the
information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid will cause the engine to enter an
idle-only condition. This will only occur
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and will be
indicated by a message in the
information display indicating required
actions to resume normal operation.
For either vehicle speed limiting or idle-only
condition, normal vehicle operation will
resume when you repair the contaminated
system. To service a contaminated or
inoperative system, see an authorized
dealer.
Diesel Exhaust Fluid guidelines and
information
• Use only diesel exhaust fluid that
carries the trademark: American
Petroleum Institute (API) certified DEF
or ISO 22241.
• Do not put diesel exhaust fluid in the
diesel fuel tank.
• Do not overfill the diesel exhaust fluid
tank. •
Do not re-use the diesel exhaust fluid
container once it is emptied.
• Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23°F (-5°C) — 68°F (20°C).
• Diesel exhaust fluid will freeze below
12°F (-11°C).
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• Do not dilute diesel exhaust fluid with
water or any other liquid.
• An ammonia odor may be smelled
when the cap is removed or during
refill. Refill diesel exhaust fluid in a well
ventilated area.
Typical Diesel Exhaust Fluid Usage
The charts below illustrate approximate
diesel exhaust fluid usage for the given
distances traveled under various driving
conditions and when using the power take
off. Your usage may vary depending on:
driving style, trailer towing, loaded vehicle
weight, weather, idle time, PTO usage.
