•Water In Fuel Indicator Light — Diesel Only
The “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the fuel
filters. If this light remains on, DO NOT start
the vehicle before you drain the water from the
fuel filters to prevent engine damage. Refer to “Mainte-
nance Procedures/Draining Fuel/Water Separator Fil-
ters” in “Maintaining Your Vehicle” for further
information.
•Wait To Start Light — Diesel Only
The “Wait To Start” telltale will illuminate for
approximately two seconds when the ignition is
turned to the RUN position. It’s duration may be longer
based on colder operating conditions. Vehicle will not
initiate start until telltale is out. Refer to “Starting Proce-
dures” in “Starting And Operating” for further
information.
NOTE:The “Wait To Start” telltale may not illuminate if
the intake manifold temperature is warm enough.•Low Diesel Exhaust Fluid Light — Diesel Only
This telltale will turn on to indicate the Diesel
Exhaust Fluid (DEF) is low.

•Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the EVIC’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”.
•Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).•Unstored Messages Until RUN
These messages deal primarily with the Remote Start
feature. This message type is displayed until the ignition
is in the RUN state. Examples of this message type are
“Remote Start Aborted - Door Ajar” and “Press Brake
Pedal and Push Button to Start”.
•Five Second Unstored Messages
When the appropriate conditions occur, this type of mes-
sage takes control of the main display area for five seconds
and then returns to the previous screen. An example of this

power reduction) is activated to protect the turbocharger
during engine start up in cold ambient temperatures.
•Engine Power Reduced During Warmup— This
message will display during start up when the ambi-
ent temperature is between 10° F (-12° C) and -10° F
(-23° C).
•
Engine Power Reduced Up To 30 Sec (Seconds) During
Warmup— This message will display during start up
when the ambient temperature is between -10° F (-23° C)
and -25 F (-32° C).
•Engine Power Reduced Up To 2 Min (Minutes)
During Warmup
