Diesel Lubrication System
It is important to change the engine oil at
the recommended service intervals or
when indicated by the information display
to maintain oil viscosity. Extending the oil
and filter change interval beyond the
recommended interval can negatively
affect engine performance, fuel economy
and engine life. See Engine Oil Check
(page 186).
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, charge air, and fuel. The
coolant serves three primary purposes: to
provide heat transfer, freeze point
protection, and corrosion protection using
additives.
Vehicles with diesel engines typically are
used to carry heavy loads and accumulate
mileage rapidly. These two factors may
cause the additives in the coolant to wear
out in a shorter time. You can find more
information about coolant additives and
coolant change intervals in the coolant
chapter. See
General Maintenance
Information (page 314). Operating the
engine with insufficient coolant or coolant
additive can cause severe engine damage. Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reduction System (page 95).
Minor Troubleshooting Guide
If the engine won ’t crank WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to the start position, the lights
become dim or go out, the battery
connections may be loose or corroded, or
the battery may be discharged. If there is
a clicking or stuttering sound coming from
the engine compartment when you turn
the key to the start position, this may also
indicate a loose or corroded battery
connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.

GENERAL INFORMATION
WARNINGS
Extended idling at high engine
speeds can produce very high
temperatures in the engine and
exhaust system, creating the risk of fire or
other damage. Do not park, idle or drive your vehicle
on dry grass or other dry ground
cover. The emission system heats up
the engine compartment and exhaust
system, creating the risk of fire. Do not start the engine in a closed
garage or in other enclosed areas.
Exhaust fumes can be toxic. Always
open the garage door before you start the
engine. If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 miles
(8 kilometers) after you reconnect it. This
is because the engine management system
must realign itself with the engine. You can
disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine. If your vehicle is operated in a heavy snow
storm or blowing snow conditions, the
engine air induction may become partially
clogged with snow and ice. If this occurs,
the engine may experience a significant
reduction in power output. At the earliest
opportunity, clear all the snow and ice
away from the air induction inlet.
IGNITION SWITCH
A (off) - The ignition is off.
Note: When you switch the ignition off and
leave your vehicle, do not leave your key in
the ignition. This could cause your vehicle
battery to lose charge.
B
(accessory) - Allows the electrical
accessories, such as the radio, to operate
while the engine is not running.
Note: Do not leave the ignition key in this
position for too long. This could cause your
vehicle battery to lose charge.
C
(on) - All electrical circuits are
operational and the warning lamps and
indicators illuminate.
D
(start) - Cranks the engine.

SWITCHING OFF THE ENGINE
Allow the engine to idle for three to five
minutes before shutting it down. The larger
the engine, the greater the need is for this
idling period.
Note:
Try to limit engine idle to 10 minutes.
Excessive idling reduces fuel economy.
ENGINE IDLE SHUTDOWN (If
Equipped) WARNING
In the event of engine shutdown,
make sure your vehicle is safely off
the road and the problem is resolved
before returning to the road. Failure to do
so may result in a crash, serious injury or
death. This feature automatically shuts down the
engine when it has been idling in park (P)
or neutral (N) for an extended period,
depending on the setting.
When the engine idle shutdown process
has started:
•
A chime sounds and a message
appears in the information display
showing a timer counting down from
30 seconds.
• You can reset the timer by pressing the
brake pedal, accelerator pedal, or by
shifting into another gear.
• If you do not intervene within 30
seconds, the engine shuts down and a
message appears in the information
display alerting you that the engine has
shut down. •
Shortly after the engine has shut down,
the electrical system simulates a key
off and even though the ignition is still
on, the electrical system simulates a
normal accessory delay period before
shutting down.
• You must switch the ignition off to
reset the system before restarting your
vehicle.
The engine idle shutdown timer does not
start if:
• The engine is operating in battery
charge protect or power take-off mode.
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER
(If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
88
F650750 (TBC), enUSA, First Printing Starting and Stopping the Engine
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness, and
lead to more costly repairs.
Readiness for
Inspection/Maintenance (I/M)
Testing
Some state/provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, you may need to have
the vehicle serviced. See On-Board
Diagnostics (OBD-II).
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, your vehicle is not ready for I/M
testing.
If the vehicle ’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that the vehicle is ready for
I/M testing.
The OBD-II system monitors the emission
control system during normal driving. A
complete check may take several days. If
the vehicle is not ready for I/M testing, you
may need to perform the following driving
cycle consisting of mixed city and highway
driving:
Drive on an expressway or highway for a
steady 15 minutes, followed by 20 minutes
of stop-and-go driving with at least four
30-second idle periods.
Allow the vehicle to sit for at least eight
hours without starting the engine. Then,
start the engine and complete the above
driving cycle. The engine must warm up to
its normal operating temperature. Once
started, do not turn off the engine until the
above driving cycle is complete. If the
vehicle is still not ready for I/M testing, you
will have to repeat the above driving cycle.

Filter System (If Equipped)
Your vehicle is equipped with a diesel
particulate filter. The diesel particulate
filter is an inline filter in the exhaust system
that reduces carbon emissions by trapping
exhaust particles before they reach the
tailpipe. The diesel particulate filter looks
similar to a traditional exhaust catalyst,
except larger, and is part of the exhaust
system under your vehicle. The filter
couples to a diesel oxidation catalyst that
reduces the amount of harmful exhaust
emitted from the tailpipe. As soot gathers
