blown bulbs, a blown protection fuse or a break in the
electrical connection.
9. Door Ajar IndicatorThis indicator will illuminate when one or
more door(s) are not fully closed.
10. Glow Plug Light — If Equipped
This vehicle will inhibit engine cranking when the
transmission oil temperature is less than –22° F
(–30° C) and the oil temperature sensor reading indicates an
engine block heater has not been used. The Glow Plug light
will flash during in cold weather for up to 10 seconds. An
externally powered electric engine block heater is available
as optional equipment or from your authorized dealer.
Turning the ignition key to the ON/RUN position illu-
minates the Glow Plug Light, the light will turn off when glow plugs reach the established temperature. You can
start the engine immediately after the light turns off.
A blinking Glow Plug Light (together with a display
message) indicates a failure on glow plugs. Please see
your authorized dealer as soon as possible.
11. Tachometer
The tachometer indicates engine speed in Revolutions
Per Minute (RPM x 1000).

Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
operation over 3200 RPM can result in significant
damage that will not be covered under the New
Vehicle Limited Warranty.

23. Generic Warning LightThe Generic Warning Light will illuminate in
blinking mode if any of the following condi-
tions occur:
• Air Bag Warning Light Fault
• Engine Oil Pressure Sensor Failure
• Parking Sensor Failure
• Water In Fuel Presence
• Fuel Cutoff Intervention
• “Engine Minimum Oil Level”
• “Engine Min Oil Sensor Fail”
• Swivel Seat Malfunction
If the Generic Warning Light is blinking an air bag system
failure may be present, see an authorized dealer as soon
as possible. 24. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
25. Tire Pressure Monitoring Telltale 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

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 opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.NOTE:
The TPMS telltale is also accompanied by a “Low
Tire” message in the Electronic Vehicle Information Cen-
ter (EVIC). Refer to “Tire Pressure Monitoring System
(TPMS) in “Starting And Operating” for further informa-
tion.
26. Seat Belt Reminder Light
When the ignition switch is first turned to
ON/RUN, during the first six seconds from
key ON, if the driver ’s seat belt is unbuckled, a
continuous chime will sound and the light will
be ON. After the first six seconds or when driving, if the
driver ’s seat belt remains unbuckled, the seat belt re-
minder light will flash or remain on continuously. This
light also indicates if the front passengers are buckled or
not (when the vehicle is equipped with the seat belt alert
also for passenger/passengers).

DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Re-
duction system to meet the very stringent diesel emis-
sions standards required by the Environmental Protec-
tion Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harm-
ful to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected
into the exhaust upstream of a catalyst where, when
vaporized, it converts 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 Reduc-
tion (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following com-
ponents:
•DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst

NOTE:If theGeneric Warning Light comes on, a
Service Fuel Filter message displays and a single chime is
heard with the ignition in the ON/RUN position or while
driving, there may there may be a problem with your
water separator wiring or sensor.
Please see your authorized dealer for service.
CAUTION!
If the “Generic Warning Lamp” remains on and a
Service Fuel Filter message displays, DO NOT
START engine before you drain the water from the
fuel filter to avoid engine damage.
Fuel Filter Replacement
Please see your authorized dealer for fuel filter replace-
ment.
Priming If The Engine Has Run Out Of Fuel
WARNING!
• Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause seri-
ous injury or death.
• Do not drain the fuel filter/water separator when
the engine is running. Fuel and fuel vapors may
escape causing as fire that can result in serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).
2. Turn the ignition to the ON/RUN position. This will activate the in-tank fuel pump for approximately
30 seconds. Repeat this process twice.
