104GETTING TO KNOW YOUR INSTRUMENT PANEL
Exhaust Service Required — See Dealer Now
— This message indicates regeneration has
been disabled due to a system malfunction.
At this point the engine Powertrain Control
Module (PCM) will register a fault code, the
instrument panel will display a MIL light.
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likelihood
of permanent damage to the after-treatment
system. If this condition is not corrected and
a dealer service is not performed, extensive
exhaust after-treatment damage can occur.
To correct this condition it will be necessary
to have your vehicle serviced by an autho -
rized dealer. NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent the
diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and reduced
engine power. Only an authorized dealer will be
able to correct this condition.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a
derate (engine power reduction) is activated to
protect the engine during start up in cold
ambient temperatures.
Engine Power Reduced During Warmup
—
This message will display during start up
when the ambient temperature is between
10°F (-12°C) and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec
(Seconds) During Warmup — This message
will display during start up when the ambient
temperature is between -10°F (-23°C) and
-25°F (-32°C).
Engine Power Reduced Up To 2 Min
(Minutes) During Warmup — This message
will display during start up when the ambient
temperature is -25°F (-32°C) and below.
Your vehicle is equipped with an engine
warm up protection feature that may limit
engine performance after cold starting at low
ambient temperatures. The length of time
engine speed is limited is dependent upon
engine coolant temperature. Engine speed
may be briefly limited to 1,000 RPM after
starting with coolant temperature below
freezing conditions, and may be limited to
1,000 RPM for up to approximately two
minutes under more severe cold conditions.
Coolant Low — This telltale will turn on to indi -
cate the vehicle coolant level is low. Refer to
“Dealer Service” in “Servicing And Mainte -
nance” for more information.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with
continued operation.

SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas
The best protection against carbon monoxide
entry into the vehicle body is a properly main -
tained engine exhaust system. Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In addi
-
tion, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change.
Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

182SAFETY
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel bolts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam indi -
cator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These objects
could change the position of the floor mat
and may cause interference with the accel -
erator, brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet
to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for inter -
ference with the accelerator, brake, or
clutch pedals then re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.
