Information display procedure
Start with your vehicle engine fully warmed
and then press the Info button on the
steering wheel until the information display
reads one of the following choices:
• EXHST XX% FULL CLEAN? Y/N
• EXHAUST FULL CLEAN? Y/N
Answer yes to this prompt and then follow
the prompts regarding exhaust position as
needed to initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished.
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning will
display
EXH AT LIMIT CLEAN? Y/N.
Answer yes to this prompt and then follow
the prompts regarding exhaust position as
needed to initiate Operator Commanded
Regeneration. Be sure to understand each
prompt. If you are not sure what is being
asked by each prompt, contact an
authorized dealer. The display will confirm
the operation has started and when it has
finished. You can also drive to clean the
filter. See Active regeneration earlier in this
chapter. When the system is at the point
of oversaturation, the service
engine soon light will illuminate
and the following message
EXH OVER
LIMIT SERVICE NOW will appear . You
will not be able to allow cleaning. You
must have your vehicle serviced by an
authorized dealer. Once operator commanded regeneration
starts, the engine
’s rpm will rise to
approximately 2,000 - 2,400 rpm and the
cooling fan will increase speed; you will
hear a change in audible sound due to the
fan and engine speed increase.
It is not necessary to open the hood on the
engine compartment. Once Operator
Commanded Regeneration is complete,
the engine rpm and fan will return to
normal idling. The exhaust system will
remain very hot for several minutes even
after regeneration is complete. Do not
reposition the vehicle over materials that
could burn until the exhaust system has
had sufficient time to cool. Depending on
the amount of soot collected by the diesel
particulate filter, ambient temperature,
and altitude, Operator Commanded
Regeneration may last from 10 to 25
minutes.
How to interrupt or cancel Operator
Commanded Regeneration
If you need to cancel the Operator
Commanded Regeneration, pressing the
brake, accelerator, or shutting off the
vehicle will stop the procedure. Depending
on the amount of time you allowed the
Operator Commanded Regeneration to
operate, soot may not have had sufficient
time to be eliminated, but the exhaust
system and exhaust gas may still be hot.
If you shut your vehicle off during Operator
Commanded Regeneration, you will notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal.
Filter service and maintenance
Over time, a slight amount of ash will build
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately 120,000
miles (193,000 km) or greater (actual

FUEL SHUTOFF
In the event of a moderate to severe
collision, this vehicle is equipped with a
fuel pump shut-off feature that stops the
flow of fuel to the engine. Not every impact
will cause a shut-off.
After an accident, if the engine cranks but
does not start, this switch may have been
activated.
This switch is located on the passenger
’s
side of the instrument panel. Open the
front passenger door and remove the small
access panel The switch has a red button on top of it.
To reset the switch:
1. Turn the ignition off.
2. Check the fuel system for leaks. 3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition on.
5. Wait a few seconds and return the key
to off.
6. Make another check for leaks.
Running Out Of DEF (Diesel
Exhaust Fluid)
If your vehicle runs out of DEF, it will enter
into a speed limited mode and can also
enter into an idle-only mode. Normal
vehicle operation will not resume until DEF
is refilled. See Selective Catalytic
Reduction System (page 21).
Contact roadside assistance for help in
finding a retailer that sells DEF. See the
Customer Assistance chapter in the
Owner ’s Manual for more information.
JUMP STARTING THE VEHICLE WARNINGS
The gases around the battery can
explode if exposed to flames, sparks,
or lit cigarettes. An explosion could
result in personal injury or vehicle damage. Batteries contain sulfuric acid which
can burn skin, eyes and clothing, if
contacted.
Use only an adequate-sized cable
with insulated clamps.
Preparing Your Vehicle
Note:
Do not attempt to push-start your
automatic transmission vehicle. Automatic
transmissions do not have push-start
capability. Attempting to push-start a
vehicle with an automatic transmission may
cause transmission damage.
