load shedding is provided for both the interior
and exterior lights.
If the ignition is OFF and any door is left ajar
for 10 minutes or the dimmer control is
rotated all the way up to the dome on position
for 10 minutes, the interior lights will auto-
matically turn off.
NOTE:
Battery saver mode is canceled if the ignition
is ON.
If the headlights remain on while the ignition
is cycled OFF, the exterior lights will auto-
matically turn off after eight minutes. If the
headlights are turned on and left on for eight
minutes while the ignition is OFF, the exterior
lights will automatically turn off.

• 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.

period of run time. Under very cold condi-
tions, it is possible that the gauge may not
reflect the new fill level for several drives.TRIP COMPUTER

marker. The warning light will flash when the
vehicle is crossing the lane marker.
Refer to “LaneSense — If Equipped" in
“Starting And Operating” for further informa-
tion.

— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. 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.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle 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.
