radiator to increase cab heater
temperature in cold climates.
CAUTION
The use of a winterfront can result in
excessive engine coolant, oil, and
charge air (intake) temperatures,
which can lead to overheating and
possible engine damage.
CAUTION
A winterfront should only be used at
temperatures below 40°F (4°C). Use
of a winterfront above 40°F (4°C) can
decrease life of cooling module com-
ponents. Remove winterfront as soon
as the ambient temp reaches 41°F
(5°C). The use of a winterfront above
40°F (4°C) can result in excessive en-
gine coolant, oil, and charge air (in-
take) temperatures, which can lead to
overheating and possible engine or
coolant module damage and emis-
sions 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.
