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 224).
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 319). 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 Reductant System (page 118).
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.

Introduction

GENERAL INFORMATION
Condensation in the Exterior Front
Lamps and Rear Lamps
Exterior front lamps and rear lamps have
vents to accommodate normal changes
in air pressure.
Condensation can be a natural by-product
of this design. When moist air enters the
lamp assembly through the vents, there is
a possibility that condensation can occur
when the temperature is cold. When
normal condensation occurs, a fine mist
can form on the interior of the lens. The
fine mist eventually clears and exits
through the vents during normal operation.
Clearing time may take as long as 48 hours
under dry weather conditions.
Examples of acceptable condensation are:
• The presence of a fine mist (no streaks,
drip marks or large droplets).
• A fine mist covers less than 50% of the
lens.
Examples of unacceptable condensation
are:
• A water puddle inside the lamp.
• Streaks, drip marks or large droplets
present on the interior of the lens.
If you see any unacceptable condensation,
have your vehicle checked by an authorized
dealer.

Engine Oil Pressure Gauge
Indicates engine oil pressure. At normal
operating temperature, the level indicator
is in the normal range. If the pressure gauge
falls below the normal range, stop your
vehicle, switch off the engine and check
the engine oil level. Add oil if needed. If the
oil level is correct, have your vehicle
checked by an authorized dealer.
Engine Coolant Temperature
Gauge
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
possible, switch off the engine and let the
engine cool.
Fuel Gauge
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located.
Note:The fuel gauge may vary slightly
when your vehicle is moving or on a slope.Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches 50 mi (80 km), 25 mi (40 km),
10 mi (20 km) and 0 mi (0 km) for all
vehicle keys.
Note:The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but
also increase or stay constant for periods
of time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop your vehicle as soon
as possible and verify the airflow is not
restricted by snow or debris blocking
airflow through the grille.
Special operating conditions such as
snowplowing, towing, or off-road use may
cause higher than normal operating
temperatures. See Special Operating
Conditions Scheduled Maintenance
(page 329).
To lower the transmission temperature
into the normal range, alter the severity of
your driving conditions. Operating the
transmission for extended periods with the
gauge in the higher than normal area may
cause internal transmission damage. If the
gauge continues to show high
temperatures, see an authorized dealer.

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle.
When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:1. Your vehicle has run out of fuel—the
engine may misfire or run poorly.
2. Poor fuel quality or water in the
fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed
properly. See Refueling (page 110).
4. Driving through deep water—the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
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 and
Maintenance (I/M) Testing
Some state and 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, your vehicle may need
service. See On-Board Diagnostics.

active regeneration. Both methods occur
automatically and require no actions from
the driver. During either one of these
regeneration methods, you may notice a
change in exhaust tone. At certain times,
various messages related to the diesel
particulate filter appear in the information
displays.
Oxidation Catalytic Converter and
Diesel Particulate Filter System (If
Equipped)
WARNING: The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle's
diesel particulate filter in order for it to
function properly.
Do not disregard maintenance messages
that appear in the information display.
Failure to follow the instructions of an
information message may degrade vehicle
performance and could lead to engine
damage that may not be covered by the
vehicle Warranty.Failure to perform active or operator
commanded regeneration when instructed
could result in a clogged diesel particulate
filter. If the diesel particulate filter fills
beyond the regeneration threshold, your
vehicle disables the ability for active and
operator commanded regeneration. This
could result in irreversible damage to the
diesel particulate filter requiring
replacement that may not be covered by
the vehicle Warranty.
Passive Regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter by oxidizing
the soot. Cleaning automatically occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full of
exhaust particles, the engine control
module commands the exhaust system to
clean the filter through active regeneration.
Active regeneration requires the engine
computer to raise the exhaust temperature
to eliminate the particles. During cleaning,
the particles convert to harmless gasses.
Once cleaned the diesel particulate filter
continues trapping exhaust particles.
The regeneration process operates more
efficiently when you drive your vehicle at
a constant speed above 30 mph
(48 km/h) and at a steady engine speed
for approximately 20 minutes. The
frequency and duration of regeneration
fluctuates by how you drive your vehicle,
outside air temperature and altitude. For
most driving, regeneration frequency varies
from 100–500 mi (160–805 km) between
occurrences and each occurrence lasts
9–35 minutes. You can usually reduce the
duration of regeneration if you maintain a
constant speed above 30 mph (48 km/h).
