ENGINE RUNAWAY
Diesel engine runaway is a rare condition affecting
diesel engines, where the engine consumes its
own lubrication oil and runs at higher and higher
RPM until it overspeeds to a point where it destroys
itself due to either mechanical failure or engine
seizure through lack of lubrication.
CAUTION!
To avoid vehicle damage, Trailer Surround
View should only be used as a parking aid. The
Trailer Surround View Camera is unable to
view every obstacle or object in your drive
path.
To avoid vehicle damage, the vehicle must be
driven slowly when using Trailer Surround
View to be able to stop in time when an
obstacle is seen. It is recommended that the
driver look frequently over his/her shoulder
when using Trailer Surround View.

170STARTING AND OPERATING
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) system to meet the very stringent
diesel emissions standards required by the
Environmental Protection Agency.
The purpose of the SCR system is to reduce levels
of NOx (oxides of nitrogen emitted from engines)
that are harmful to our health and the environment
to a near-zero level. A small quantity of Diesel
Exhaust Fluid (DEF) is injected into the exhaust
upstream of a catalyst where, when vaporized, it
converts smog-forming nitrogen oxides (NOx) into
harmless nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe. You can
operate with the comfort that your vehicle is
contributing to a cleaner, healthier world
environment for this and generations to come.
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid
(DEF) injection system and a Selective Catalytic
Reduction (SCR) catalyst to meet the emission
requirements.
The DEF injection system consists of the following
components:
DEF tank
DEF pump
DEF injector
Electronically-heated DEF lines
DEF control module
NOx sensors
Temperature sensors
SCR catalyst
UQS Sensor
For system messages and warnings Ú page 81.
NOTE:
Your vehicle is equipped with a DEF injection
system. You may occasionally hear an audible
clicking noise. This is normal operation.
The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This
is normal operation.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very
stable product with a long shelf life. If DEF is kept
in temperatures between 10° and 90°F (-12° and
32°C), it will last a minimum of one year.
DEF is subject to freezing at the lowest
temperatures. For example, DEF may freeze at
temperatures at or below 12°F (-11°C). The
system has been designed to operate in this
environment.
NOTE:When working with DEF, it is important to know
that:
Any containers or parts that come into contact
with DEF must be DEF compatible (plastic or
stainless steel). Copper, brass, aluminum, iron
or non-stainless steel should be avoided as they
are subject to corrosion by DEF.
If DEF is spilled, it should be wiped up
completely.
Adding Diesel Exhaust Fluid (DEF)
The DEF gauge (located on the instrument cluster)
will display the level of DEF remaining in the tank
Úpage 81.
NOTE:
Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in
your vehicle.
Another factor is that outside temperature can
affect DEF consumption. In cold conditions,
12°F (-11°C) and below, the DEF gauge needle
can stay on a fixed position and may not move
for extended periods of time. This is a normal
function of the system.
There is an electric heater inside the DEF tank
that automatically works when necessary. If the
DEF supply does freeze, the truck will operate
normally until it thaws.

DEF FILL PROCEDURE
NOTE:
For the correct fluid type Ú page 404.
Remove cap from DEF tank (located on drivers side
of the vehicle or in fuel door).

DEF Filler Cap And Fuel Fill Chassis Cab Models

NOTE:
The DEF gauge may take up to five seconds to
update after adding a gallon or more of 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 possibly 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.
At 40°F (4°C) you could see some increase in
the DEF gauge due to the tank thawing. The
gauge and level sensor are working properly and
are just updating with proper thawed DEF.
Excessive overfilling of the DEF tank can result
in a MIL lamp/fault code and inaccurate level
readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler tube, start
refilling and stop refilling at the first shut-off (the
shut-off indicates that the DEF tank is full). DO
NOT proceed with the refilling, to prevent
spillage of DEF.
Extract the nozzle. 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.
After the indication appears on the instrument
cluster display
Úpage 81 fill the DEF tank with
no more than 6 gallons (22 liters).
1 — Diesel Exhaust Fluid (DEF) Fill Location
2 — Diesel Fuel Fill Location
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.

Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and
Electric Over Hydraulic (EOH) trailer brakes.
NOTE:This module has been designed and verified with
electric trailer brakes and new electric over
hydraulic systems. Some previous EOH systems
may not be compatible with ITBM.

Integrated Trailer Brake Module (ITBM)
The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to
activate power to the trailer's electric brakes
independent of the tow vehicle's brakes. If the
manual brake control lever is activated while the
brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come
on when braking normally with the vehicle brake
pedal. Only the trailer stop lamps will come on
when the manual brake control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection
status.
If no electrical connection is detected after the
ignition is turned on, pushing the GAIN adjustment
button or sliding the manual brake control lever
will display the GAIN setting for 10 seconds and the
Trailer Brake Status Indicator Light will not be
displayed.

If a fault is detected in the trailer wiring or the ITBM,
the Trailer Brake Status Indicator Light will flash.

GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control
power output to the trailer brakes in
0.5 increments. The GAIN setting can be increased
to a maximum of 10 or decreased to a minimum of
0 (no trailer braking). GAIN
The GAIN setting is used to set the trailer brake
control for the specific towing condition and should
be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle
load, road conditions and weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic-free envi
-
ronment at speeds of approximately 20–25 mph
(30–40 km/h).

1. Make sure the trailer brakes are in good working condition, functioning normally and
properly adjusted. See a trailer dealer if
necessary.

2. Hook up the trailer and make the electrical connections according to the trailer
manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message
should appear in the instrument cluster
display (if the connection is not recognized by
the ITBM, braking functions will not be
available), the GAIN setting will illuminate and
the correct type of trailer must be selected
from the instrument cluster display options.

control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the
trailer wheels turn freely, increase the GAIN
setting. Repeat steps 8 and 9 until the GAIN setting is at a
point just below trailer wheel lockup. If towing a
heavier trailer, trailer wheel lockup may not be
attainable even with the maximum GAIN setting of
10.
* The suggested selection depends and may change depending on the customer preferences for braking performance. Condition of the trailer brakes, driving and road state may also
affect the selection.
Display Messages
