INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Seat Belt Reminder LightWhen 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 “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” in your Owner Manual on
the DVD for further information. 3. 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.

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.
11. Parking Brake Indicator
This light indicates the parking brake is engaged.

NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel 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
12°F (-11°C). 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.

fuel may offer improved cold-starting and warm-up
performance.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-

Fuel Specifications
This diesel engine has been developed to take advantage
of the high energy content and generally lower cost No. 2
Ultra Low Sulfur diesel fuel or No. 2 Ultra Low Sulfurclimatized diesel fuels. Experience has shown that it also
operates on No. 1 Ultra Low Sulfur diesel fuels or other
fuels within specification.
NOTE:
•
If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, do not start the vehicle. If you restart
your vehicle you risk damage the engine and fuel
system. Please call your authorized dealer for service.
• A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your diesel
engine without any adjustments to regular service
schedules.
• Commercially available fuel additives are not neces-
sary for the proper operation of your diesel engine.
• No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.

STARTING AND OPERATING 45

CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a
single chime are heard while you are driving, or with the
ignition in the ON position, there may be a problem with
your water separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from fuel filter
assembly, the “Water In Fuel Indicator Light” will remain
illuminated for approximately 10 seconds. If the water
was drained while the engine was running, the “Water In
Fuel Indicator Light” may remain on for approximately
three minutes. NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact an authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain the fuel/water separator filters when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the filter drain valve (located on the
bottom of the filter housing) counterclockwise to drain
fuel/water, then turn the ignition switch to the ON
position, and allow any accumulated water to drain.
Leave the drain valve open until all water and contami-
nants have been removed. When clean fuel is visible,
close the drain valve by turning it clockwise, and turn the
ignition switch to OFF.

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” for further in-
formation
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the housing
when the new filter is installed if the residual oil is not
either removed from the housing or enough time has not
elapsed to allow the oil to drain back into the engine.
When servicing the oil filter on this engine, carefully
remove the filter and use a suction gun to remove any
residual oil left in the housing or wait about 30 minutes
for the oil to drain back into the engine.
