4. Press the trip/fuel button untilthe vehicle heading, for
example, N for North, is
displayed in the DIC. Or, if the
vehicle does not have DIC
buttons, press and hold the trip
odometer reset stem for
two seconds to select the next
available variance zone. Repeat
this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass. See
“Compass Calibration
Procedure” following. Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger.
It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change
after making turns, there may be a
strong magnetic field interfering with
the compass. Such interference
may be caused by a magnetic CB or
cell phone antenna mount, a
magnetic emergency light, magnetic
note pad holder, or any other
magnetic item. Turn off the vehicle, move the magnetic item, then turn
on the vehicle and calibrate the
compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone is
set to the variance zone in which
the vehicle is located. See
“Compass Variance (Zone)
Procedure” earlier in this
section.
Do not operate any switches
such as window, sunroof,
climate controls, or seats during
the calibration procedure.
2. Press the vehicle information button until PRESS
VTO
CALIBRATE COMPASS

Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player.
There are two under the climate
controls, one inside the center floor
console, one on the rear of the
center floor console and one
accessory power outlet in the rear
cargo area on the passenger side.
Remove the cover to access and
replace when not in use.The accessory power outlets are
powered, even with the ignition off.
Continuing to use accessory power
outlets while the ignition is in LOCK/
OFF may cause the vehicle's
battery to run down.
{WARNING
Power is always supplied to the
outlets. Do not leave electrical
equipment plugged in when the
vehicle is not in use because the
vehicle could catch fire and cause
injury or death.
Notice: Leaving electrical
equipment plugged in for an
extended period of time while the
vehicle is off will drain the
battery. Always unplug electrical
equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating. Certain accessory plugs may not be
compatible with the accessory
power outlet and could overload
adapter or vehicle fuses. If a
problem is experienced, see your
dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. Do not use
equipment exceeding the
maximum amperage rating of
20 amperes. See
Add-On Electrical
Equipment on page 9‑97.
Notice: Hanging heavy
equipment from the power outlet
can cause damage not covered
by the vehicle warranty. The
power outlets are designed for
accessory power plugs only, such
as cell phone charge cords.

Messages on page 5‑46 for more
information.Vehicle Messages
Messages displayed on the DIC
indicate the status of the vehicle or
some action may be needed to
correct a condition. Multiple
messages may appear one after
another.
The messages that do not require
immediate action can be
acknowledged and cleared by
pressing
V(Set/Reset) or the trip
odometer reset stem.
The messages that require
immediate action cannot be cleared
until that action is performed.
All messages should be taken
seriously and clearing the message
does not correct the problem.
The following are the possible
messages and some information
about them.
Battery Voltage and
Charging Messages
BATTERY LOW START
VEHICLE
When the vehicle’ s battery is
severely discharged, this message
will display and four chimes will
sound. Start the vehicle
immediately. If the vehicle is not
started and the battery continues to
discharge, the climate controls,
heated seats, and audio systems
will shut off and the vehicle may
require a jump start. These systems
will function again after the vehicle
is started.

The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY LOW
START VEHICLE . If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. See
Battery Voltage and
Charging Messages on page 5‑38.
Battery Power Protection
This feature shuts off the dome, and
reading lamps if they are left on for
more than 10 minutes when the
ignition is off. This will keep the
