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 Electronic Vehicle
Information Center (EVIC).
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”.
When the “Perform Service” message is displayed on the EVIC it is necessary to have
the emissions maintenance performed.
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 Service Required — See Dealer Now
This message indicates regeneration has been disabled due to a system malfunction.
The Powertrain control Module (PCM) will register a fault code and the instrument
panel will display the Malfunction Indicator Light (MIL).
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur soon
with continued operation.
Exhaust Filter Full — Power Reduced See Dealer
The PCM derates the engine in order 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. Have your
vehicle serviced by your local authorized dealer.
CAUTION!
See your authorized dealer, as damage to the exhaust system could occur with the
exhaust filter full.
DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known simply by the name of its active
component, UREA – is a key component of selective catalytic reduction (SCR)
systems, which help diesel vehicles meet stringent emission regulations. DEF is a
liquid reducing agent that reacts with engine exhaust in the presence of a catalyst to
convert smog-forming nitrogen oxides (NOx) into harmless nitrogen and water vapor.
Your vehicle is equipped with a Selective Catalytic Reduction system in order to meet
the very stringent diesel emissions standards required by the Environmental Protec-
tion Agency. Selective Catalytic Reduction (SCR) is the first and only technology in
decades to be as good for the environment as it is good for business and vehicle
performance.
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.

INSTRUMENT CLUSTER WARNING LIGHTS
- 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) when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure EVIC 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.
WHAT TO DO IN EMERGENCIES
150

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 display.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a TPMS, as damage to the sensors
may result.
- Seat Belt Reminder Light
When the ignition switch is first turned to the ON/RUN position, this light will turn on
for four to eight seconds as a bulb check. During the bulb check, if the driver's seat
belt is unbuckled, a chime will sound. After the bulb check or when driving, if the
driver or front passenger seat belt remains unbuckled, the Seat Belt Indicator Light
will flash or remain on continuously. Refer to “Seat Belts” in “Getting Started” of this
user guide for further information.
WHAT TO DO IN EMERGENCIES
151

- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on it may indicate that the parking brake is
applied, that the brake fluid level is low, or that there is a problem with the anti-lock
brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS), are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is applied with the ignition switch
in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree
of brake application.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.

- 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 tempera-
tures 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 Indicator
Light” 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.
WHAT TO DO IN EMERGENCIES
153

• 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.
• To improve the vehicle's traction when starting off in deep snow, sand or gravel, it
may be desirable to switch the ESC system to Partial Off mode by momentarily
pressing the ESC Off
switch located below the climate controls, on the switch
panel.
- Electronic Stability Control (ESC) OFF Indicator Light
This light indicates the Electronic Stability Control (ESC) is off.
- Charging System Light

light remains on, it means that the vehicle is experiencing a problem with the
charging system.
We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However,
the conventional brake system will continue to operate normally if the BRAKE
warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
