Battery Replacement
Replace the battery if the
REPLACE BATTERY IN REMOTE
KEY message displays in the DIC.
See“REPLACE BATTERY IN
REMOTE KEY” underKey and
Lock Messages on page 5‑42 for
additional information.
Notice: When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage the
transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat
head screwdriver.
.Carefully insert the tool
into the notch located
along the parting line of the
transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
.Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive
side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
If available, this feature allows you
to start the engine from outside of
the vehicle. It may also start up the
vehicle's heating or air conditioning
systems and rear window defogger.
Normal operation of the system will
return after the key is turned to the
ON/RUN position.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off.

During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and will
shut off when the key is turned to
ON/RUN. If the vehicle does not
have an automatic climate control
system, during remote start,
manually turn the heated seats on
and off. SeeHeated Front Seats on
page 3‑9 for additional information.
Laws in some communities may
restrict the use of remote starters.
For example, some laws may
require a person using the remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
Do not use the remote start feature
if the vehicle is low on fuel. The
vehicle may run out of fuel. If the vehicle has the remote
start feature, the RKE transmitter
functions will have an increased
range of operation. However, the
range may be less while the vehicle
is running.
There are other conditions which
can affect the performance of the
transmitter. See
Remote Keyless
Entry (RKE) System on page 2‑2 for
additional information.
/(Remote Start): This button
will be on the RKE transmitter if the
vehicle has remote start.
To start the vehicle using the remote
start feature:
1. Aim the transmitter at the
vehicle.
2. Press and release
Q. The
vehicle's doors will lock.
Immediately press and
hold
/until the turn signal
lamps flash. If you cannot see
the vehicle's lamps, press and
hold
/for two to four seconds. Pressing
/again after the
vehicle has started will turn the
engine off.
When the vehicle starts, the
parking lamps will turn on and
remain on while the vehicle is
running.
If the vehicle is left running,
it will automatically shut off
after 10 minutes unless a time
extension has been done.
3. If it is the first remote start since the vehicle has been
driven, repeat these steps,
while the engine is still running,
to extend the engine running
time by 10 minutes. Remote start
can be extended one time.
After entering the vehicle during a
remote start, insert and turn the key

3. Press the set/reset button toscroll through and select the
appropriate variance zone.
4. Press the trip/fuel button until the 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
displays. Or, if the vehicle
does not have DIC buttons,
press the trip odometer reset
stem until CALIBRATE
COMPASS displays.

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 9‑94.
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.
