When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories con-
nected to the outlet(s) should be removed or
turned off when the vehicle is not in use to
protect the battery against discharge.WARNING!
To avoid serious injury or death:
• Only devices designed for use in this type of outlet should be inserted into any
12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while
driving the vehicle.
• If this outlet is mishandled, it may cause
an electric shock and failure.
CAUTION!
•Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long
enough, the vehicle's battery will discharge
sufficiently to degrade battery life and/or
prevent the engine from starting.
• Accessories that draw higher power (i.e.,coolers, vacuum cleaners, lights, etc.),
will discharge the battery even more
quickly. Only use these intermittently
and with greater caution.
CAUTION!
• After the use of high power draw acces-sories, or long periods of the vehicle not
being started (with accessories still
plugged in), the vehicle must be driven a
sufficient length of time to allow the
generator to recharge the vehicle's bat-
tery.

Diesel Messages And Warnings
— 6.7L Cummins Diesel Engine
Diesel Particulate Filter (DPF) Messages
The Cummins diesel engine meets all diesel
emissions standards, resulting in one of the
lowest emitting diesel engines ever pro-
duced. To achieve these emissions stan-
dards, 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 Con-
trol Module (PCM). The PCM manages enginecombustion to allow the exhaust system’s
catalyst to trap and burn Particulate Matter
(PM) pollutants, with no input or interaction
on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to
additional maintenance required on your ve-
hicle or engine. The following messages may
display in your instrument cluster display:
• Perform Service — Your vehicle will require
emissions maintenance at a set interval. To
help remind you when this maintenance is
due, the instrument cluster display will
display “Perform Service”. When the “Per-
form Service” message is displayed in the
instrument cluster display it is necessary to
have the emissions maintenance per-
formed. Emissions maintenance may in- clude replacing the Closed Crankcase Ven-
tilation (CCV) filter element. The procedure
for clearing and resetting the "Perform Ser-
vice" indicator message is located in the
appropriate Service Information.
• Exhaust System — Regeneration Required
Now — "Exhaust Filter XX% Full Safely
Drive at Highway Speeds to Remedy" will
be displayed in the instrument cluster dis-
play if the exhaust particulate filter reaches
80% of its maximum storage capacity. Un-
der conditions of exclusive short duration
and low speed driving cycles, your Cum-
mins diesel engine and exhaust after-
treatment system may never reach the con-
ditions required to remove the trapped PM.
If this occurs, the “Exhaust Filter XX% Full
Safely Drive at Highway Speeds to Rem-
edy” message will be displayed in the in-
strument cluster display. If this message is
displayed, you will hear one chime to assist
in alerting you of this condition
By simply driving your vehicle at highway
speeds for as little as 45 minutes, you can
remedy the condition in the particulate filter
system and allow your Cummins diesel en-
gine and exhaust after-treatment system to

WARNING LIGHTS AND MESSAGES
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or pas-
senger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or
ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound. Refer to “Occupant Restraints Sys-
tems” in “Safety” for further information.
— Air Bag Warning Light
This light indicates a fault with the air bag,
and will turn on for four to eight seconds as a
bulb check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light
will illuminate with a single chime when a
fault with the air bag has been detected, it
will stay on until the fault is cleared. If thelight is either not on during startup, stays on,
or turns on while driving, have the system
inspected at an authorized dealer as soon as
possible.
— 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 Con-
trol (ESC) system. In this case, the light will
remain on until the condition has been cor-
rected. 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 indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair
is necessary.
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.

Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic 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 re-
quired.
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 illumi-
nate, have the light inspected by your autho-
rized 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.— Vehicle Security Warning Light — If
