NOTE:
If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check fuse block
for blown fuses. Refer to the label located on the inside of
the fuse block cover for the proper airbag fuses. See your
dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5-seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, or near deployment,
and up to a quarter second of high-speed deceleration
data during and/or after airbag deployment. EDR data
are
ONLY recorded
if
an
airbag
deploys,
or
nearly
deploys, and are otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by DaimlerChrysler Corporation and others to learn
more about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.

lighter” plug. The outlet is located in the instrument
panel below and to the right of the Climate Control
Panel. A cap is attached to the outlet base indicating
“Power Outlet” 12V-20A.
There is an additional Power Outlet inside the center
console of vehicles equipped with 40/20/40, or Bucket
front seats. There is also a Power Outlet located on the
rear of the center console for Quad Cab or Mega Cab
vehicles (only) equipped with bucket seats.
The outlet(s) has/have a fused direct feed from the
battery so it/they receive power whether the ignition is
ON or OFF.
All accessories connected to this/these outlet(s) should
be removed or turned OFF when the vehicle is not in use
to protect the battery against discharge.
NOTE:
If desired, all of the power outlets can be
converted by your authorized dealer to provide power
with the ignition switch in the ON position only.

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Integrated Power Module, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:
When reinstalling the IOD fuse push firmly until
fully seated, the gages in the Instrument Cluster will do
a full sweep, when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:
When the vehicle is shipped from the factory,
the IOD fuse is in the up, or extracted position. If the
radio, interior lamps, keyless entry, or other features do
not work with the key off, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the instru-
ment cluster, in the odometer window, will display

Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel.
Sunroof Fully Closed
Press the switch forward and release to ensure that the
sunroof is fully closed.
ELECTRICAL POWER OUTLETS
The auxiliary electrical outlet can provide power for in

The TPMS system will always reset to the max load
inflation pressure (cold) low pressure warning thresh-
old condition when the system experiences a loss of
electrical power. For example, by momentarily discon-
necting the battery or IOD fuse.
To switch from the max load inflation pressure (cold) low
pressure warning threshold to the light load inflation
pressure
(cold)

threshold,
the
driver must first lower all four road tire pressures to the
Light Load Inflation Pressure values as listed on the

label.
The
Supplemental Tire Pressure Information label is located
on the rear face of the driver door. Use an accurate tire
gauge to check the tire pressures when lowering all four
tire pressures. Next proceed to turning the ignition on to
the Run position. This may cause the TPMS low pressure
warning telltale lamp located in the Instrument Cluster to
turn ON and a chime to sound since the tire pressures
have been lowered below the max load inflation pressure
(cold) pressures. After all four tire pressures have been
lowered to the Light Load inflation pressures, press the
“Light Load” reset switch. If the “Light Load” switch
