DIESEL FUEL FILTERS/WATER SEPARATOR
Draining Fuel/Water Separator
If the “Water in Fuel” indicator light
is illuminated and an audible chime
is heard five times, you should stop the
engine and drain the water from the sepa-
rator.
The best access to this water drain valve
is from under the vehicle.
The drain valve is located on the bottom
of the Fuel Filter and Water Separator
assembly which is located on the left side
of the vehicle in front of the fuel tank.
1. Loosen the drain valve (located on the bottom of the filter assembly) then
turn the ignition switch to the ON/
RUN position to allow any accumu-
lated water to drain.
2. When clean fuel is visible, close the drain and switch the ignition to the OFF position.
Refer to the Diesel Supplement on the DVD for further details.
Fuel Filter Replacement
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve.
5. Remove using a socket. Rotate counterclockwise for removal.
6. Remove the used filter cartridge from the housing and dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Lubricate o-ring on new filter with clean engine oil.
9. Repeat steps 5 through 8 to service second filter in fuel filter assembly.

CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into anappropriate container.
• Do not prefill the fuel filter when installing a new fuel filter. There is a
possibility debris could be introduced into the fuel filter during this action. It
is best to install the filter dry and allow the in-tank lift pump to prime the fuel
system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the engine
before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
This engine meets all required EPA diesel engine emissions standards. To achieve
these emissions standards, your vehicle is equipped with a state-of-the-art engine
and exhaust system. These systems are seamlessly integrated into your vehicle and
managed by the Powertrain Control Module (PCM). Additionally, your vehicle has the
ability to alert you to additional maintenance required on your vehicle or engine.
Refer to the following messages that may be displayed on your Driver Information
Display (DID).
Exhaust System — Regeneration Required Now
This message Indicates that the Diesel Particulate Filter (DPF) reached 80% of its
maximum storage capacity.
By simply driving your vehicle at highway speeds for up to 20 minutes, you can
remedy the condition in the particulate filter system and allow your diesel engine and
exhaust after-treatment system to cleanse the filter to remove the trapped PM and
restore the system to normal operating condition.
Exhaust System — Regeneration in Process Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is self-cleaning. Maintain your
current driving condition until regeneration is completed.
Exhaust System — Regeneration Completed
This message indicates that the Diesel Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed, you will hear one chime to assist in alerting
you of this condition.

The purpose of the SCR system is to reduce levels of NOx (oxides of nitrogen emitted
from engines) that are harmful to our health and the environment to an almost
near-zero level. Small quantities of Diesel Exhaust Fluid (DEF) are injected into the
exhaust upstream of a catalyst where, when vaporized, convert smog-forming
nitrogen oxides (NOx) into harmless nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe. You can operate with the comfort that your
vehicle is contributing to a cleaner, healthier world environment for this and
generations to come.
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst enable the achievement of diesel
emissions requirements; while maintaining outstanding fuel economy, drivability,
torque and power ratings.
NOTE:
• Your vehicle is equipped with a DEF injection system. You may occasionally hearan audible clicking noise. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF system. This is normal operation.

Adding Diesel Exhaust Fluid
The DEF gauge (located in the DID) will display the level of DEF remaining in the
tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Driver Information Display (DID).
NOTE:
• The gauge may take up to five seconds to update after adding a gallon or more ofDiesel Exhaust Fluid (DEF) to the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately update after a refill if the temperature of the DEF fluid is below 12F (-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period of run time. Under very cold
conditions, it is possible that the gauge may not reflect the new fill level for several
drives.
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the
amount of DEF that is used in your
vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with
an automatic DEF heating system.
This allows the DEF injection system to
operate properly at temperatures be-
low 12°F (-11°C).

– Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the gear selector is placed in
the PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when
the engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require
towing.
– Tire Pressure Monitoring System (TPMS) Light
Each tire, including the spare (if provided), should be checked monthly, when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a Tire Pressure
Monitoring System (TPMS) which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID) when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire pressure EVIC or DID
display illuminates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping
ability.
IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
After inflation, the vehicle may need to be driven for 20 minutes before the flashing light
will turn off.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the TPMS low EVIC or DID display.

– Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of an onboard diagnostic system called
OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition
checked promptly.
Certain conditions, poor fuel quality, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive normally and will not require
towing.
CAUTION!
Prolonged driving with the Malfunction Indicator Light (MIL) on could cause
damage to the engine control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic converter damage and power
loss will soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced above, can reach higher
temperatures than in normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious injury to the driver, occupants
or others.
– Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator Light” in the instrument cluster will
come on when the ignition switch is turned to the ON/RUN position. It should go out
with the engine running. If the “ESC Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see your
authorized dealer as soon as possible to have the problem diagnosed and corrected.
NOTE:
• The “ESC Off Indicator Light” and the “ESC Activation/Malfunction IndicatorLight” come on momentarily each time the ignition switch is turned to ON/RUN.
• Each time the ignition is turned to ON/RUN, the ESC system will be ON, even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
