WHAT IS THE DIESEL
PARTICULATE FILTER

The diesel particulate filter is part of your
vehicle's emissions system and filters
harmful diesel particulates from the
exhaust gas.

HOW DOES THE DIESEL
PARTICULATE FILTER WORK

The diesel particulate filter reduces carbon
emissions by trapping exhaust particles
before they reach the tailpipe. The system
must periodically clean the exhaust
particles that gather inside the filter. This
is carried out in three ways, passive
regeneration, active regeneration and
manual regeneration.

Passive Regeneration

In passive regeneration, the normal
exhaust system temperature cleans the
filter by oxidizing the soot. Cleaning occurs
during normal vehicle operating conditions
due to driving patterns.

Active Regeneration

Once the diesel particulate filter is full,
active regeneration raises the exhaust
temperature to eliminate the particles.
During cleaning, the particles convert to
harmless gasses.

When the engine control module detects
that the diesel particulate filter is nearly
full of particulates, and you are not
operating your vehicle in a manner to allow
effective regeneration, messages appear
in the information display as a reminder
for you to drive your vehicle in order to
clean the diesel particulate filter. If you
drive your vehicle in a manner to allow
effective regeneration, the information
display shows a cleaning exhaust filter
message.

DIESEL PARTICULATE FILTER
PRECAUTIONS

WARNING:

Do not park or idle your

vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.

WARNING:

When the

Exhaust

Filter Cleaning

message appears in the

information display, do not park near
flammable materials, vapors or
structures until filter cleaning is
complete.

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.

Note:

Avoid running out of fuel.

Note:

During regeneration at low speed or

engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.

Note:

Changes in the engine or exhaust

sound may be heard during the regeneration
process.

212

Diesel Particulate Filter

Failure to perform active or manual
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 manual
regeneration. This could result in
irreversible damage your vehicle Warranty
may not cover.

DIESEL PARTICULATE FILTER
REQUIREMENTS

The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function.

If your journeys meet one of the following
conditions:
•

You drive only short distances.

•

You frequently switch the ignition on
and off.

•

Your journeys contain a high level of
acceleration and deceleration.

You must carry out occasional trips with
the following conditions to assist the
regeneration process:
•

Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.

•

Avoid prolonged idling and observe
speed limits and road conditions.

•

Do not switch the ignition off.

•

Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION

WHAT IS DIESEL PARTICULATE
FILTER MANUAL REGENERATION

Diesel particulate filter manual
regeneration allows you to manually start
regeneration of the diesel particulate filter
at idle to clean the filter.

Note:

If you are not sure whether your

vehicle has this feature, contact your
authorized dealer.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
PRECAUTIONS

WARNING:

Stay clear of the

exhaust tailpipe during regeneration. Hot
exhaust gases can burn you badly.

You may not be able to use manual
regeneration if the service engine soon
warning lamp appears in the information
display.

Note:

During the use of manual

regeneration, you may observe a light
amount of white smoke. This is normal.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
REQUIREMENTS

You can use the manual regeneration
feature when a message appears in the
information display and you are not able
to drive in a manner that allows effective
automatic active regeneration or if you
choose to manually start the regeneration
of the diesel particulate filter while the
vehicle is idle.

213

Diesel Particulate Filter

Before you start manual regeneration, do
the following:
•

Shift into park (P) and apply the
parking brake, on stable, level ground.

•

Park your vehicle outside of any
structure.

•

Park your vehicle 10–15 ft (3–5 m)
away from any obstructions and away
from materials that can easily combust
or melt, for example paper, leaves,
petroleum products, fuels, plastics and
other dry organic material.

•

Make sure there is a minimum of 1/8
tank of fuel.

•

Make sure all fluids are at proper levels.

DIESEL PARTICULATE FILTER
MANUAL REGENERATION
LIMITATIONS

You cannot use manual regeneration until
the diesel particulate filter load percentage
has reached 100%. The diesel particulate
filter load percentage fluctuates up and
down when driving your vehicle due to
active and passive regenerations.

If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system.

Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.

STARTING DIESEL PARTICULATE
FILTER MANUAL REGENERATION

Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See

Instrument Cluster Display

(page 141).

If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See

Diesel Particulate Filter – Information
Messages

(page 215). Answer yes to this

prompt and then follow the next prompts
regarding exhaust position required to
initiate manual 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
confirms the operation has started and
when it has finished. You can also drive to
clean the filter.

When the system is at the point
of oversaturation, the service
engine warning lamp illuminates

and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.

Once manual regeneration starts, engine
speed increases to approximately 1600
rpm and the cooling fan speed increases.
You will hear a change in audible sound
due to engine speed and cooling fan speed
increases.

It is not necessary to open the hood on the
engine compartment. Once manual
regeneration completes, the engine speed
returns to normal idling. The exhaust
system remains very hot for several
minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the

214

Diesel Particulate Filter

exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude, manual
regeneration lasts approximately 30
minutes.

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM

The selective catalytic reduction system
helps reduce emission levels of oxides of
nitrogen from the exhaust system.

HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK

The selective catalytic reduction system
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.

SELECTIVE CATALYTIC
REDUCTION SYSTEM
PRECAUTIONS

WARNING:

Keep diesel exhaust

fluid out of reach of children. Avoid
contact with skin, eyes or clothing. In
case of contact with your eyes, flush
immediately with water and get prompt
medical attention. In case of contact
with your skin, clean immediately with
soap and water. If you swallow any
diesel exhaust fluid, drink plenty of
water, call a physician immediately.

WARNING:

Only refill the diesel

exhaust fluid tank in a well ventilated
area. When you remove the diesel
exhaust fluid tank filler cap or a diesel
exhaust fluid container cap, ammonia
vapors may escape. Ammonia vapors
can be irritating to skin, eyes and mucous
membranes. Inhaling ammonia vapors
can cause burning to the eyes, throat and
nose and cause coughing and watery
eyes.

WARNING:

Diesel exhaust fluid

must be refilled when low or replaced
when contaminated or your vehicle
speed becomes limited to 50 mph
(80 km/h). In these conditions, drive with
caution and refill diesel exhaust fluid
immediately. If the diesel exhaust fluid
becomes empty or contaminated and
fluid is not replaced, your vehicle
becomes limited to engine idle only once
stopped. In these conditions, be cautious
where you stop your vehicle because you
may not be able to drive long distances
or maintain highway speeds until you
refill or replace the diesel exhaust fluid.

WARNING:

Tampering with or

disabling the selective catalytic
reduction system results in severe
vehicle performance limitation including
eventual speed limiting to 5 mph
(8 km/h).

Note:

Do not put diesel exhaust fluid in the

fuel tank. This can cause damage that your
vehicle Warranty may not cover.

Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality.

217

Selective Catalytic Reduction System

Driving without refilling, replacing
contaminated diesel exhaust fluid, or
having the selective catalytic reduction
system repaired results in the following
actions as required by the California Air
Resources Board (CARB) and the U.S.
Environmental Protection Agency (EPA):
•

Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.

•

Further vehicle operation without
refilling or replacing contaminated
diesel exhaust fluid causes the engine
to enter an idle-only condition. This
only occurs upon vehicle refueling,
vehicle idling in park for 1 hour, or
engine shutdown for 10 minutes or
more and is indicated by a message in
the information display indicating
required actions to resume normal
operation. It is required to add a
minimum of 1.0 gal (3.8 L) of diesel
exhaust fluid to the tank to exit the
idle-only condition, but your vehicle is
still in the speed-limiting mode until
you refill the tank completely.

Note:

For vehicle speed limiting or idle-only

condition, normal vehicle operation resumes
when you refill the diesel exhaust fluid tank
or repair the contaminated system. If the
system is contaminated or inoperative, have
your vehicle checked as soon as possible.
