radiator to increase cab heater
temperature in cold climates.
CAUTION
The use of a winterfront can result in exces-
sive engine coolant, oil, and charge air (in-
take) temperatures, which can lead to over-
heating and possible engine damage.
CAUTION
A winterfront should only be used at temper-
atures below 40°F (4°C). Use of a winter-
front above 40°F (4°C) can decrease life of
cooling module components. Remove win-
terfront as soon as the ambient temp reach-
es 41°F (5°C). The use of a winterfront
above 40°F (4°C) can result in excessive
engine coolant, oil, and charge air (intake)
temperatures, which can lead to overheating
and possible engine or coolant module dam-
age and emissions non-compliance.
The winterfront is designed to minimize the
temperature differences across the radiator
and reduce the possibility of cooling
module damage. Aftermarket winterfronts
may not provide the proper airflow
distribution and could cause cooling
module damage.
Engine Control Display
Your vehicle may come with an optional
Engine and Driver Information Display.
This instrument records information on
engine diagnostics, scheduled
maintenance, driving conditions, and
general trip information. The specific
features of your display may vary
depending on engine make.
What is Exhaust Aftertreatment
Vehicles manufactured with diesel engines
have an exhaust Aftertreatment System
(ATS) to control vehicle exhaust emissions.
The system consists of a Diesel Particulate
Filter (DPF), Selective Catalyst Reduction
(SCR), Regeneration Switch and warning
lights. The DPF will trap soot from the
engine exhaust gases. The SCR uses
Diesel Exhaust Fluid to reduce the levels of
NOx in the engine exhaust. The ATS will
periodically clean (regenerate) the DPF.
Please refer to the Exhaust Aftertreatment
System Supplement provided with the
vehicle for more detailed description of
functionality and warnings.
Cruise Control
This vehicle has cruise control. Cruise
control functions and features may vary
depending upon which engine you have.
For specific explanation of your cruise
control, see the cruise control or engine
manual included with your vehicle.
This vehicles electronic system will perform
a ‘rationality check’ every time the vehicle
is started. This check is to ensure that the
service brakes are working before allowing
cruise control to function. This safety
feature is designed to ensure that a driver
is able to cancel the cruise set speed by
using the service brake pedal. The system
will not allow cruise control operation if it
does not pass the ‘rationality check.’ The
instrument cluster will prompt you to press
the service brake pedal if it has not been
