5-44 Instruments and Controls
The following conditions may
cause this message to appear.
.Driver-added equipment plugged
into the accessory power outlet
on the center console is causing
interference. Examples of these
devices are cell phones and cell
phone chargers, two-way radios,
power inverters, or similar items.
Try moving the RKE transmitter
away from these devices when
starting the vehicle. In addition,
PDA devices and remote garage
and gate openers may also
generate Electromagnetic
Interference (EMI) that may
interfere with the RKE
transmitter. Do not carry the
RKE transmitter in the same
pocket or bag as these devices.
.The vehicle is experiencing
Electromagnetic
Interference (EMI). Some
locations, such as airports,
automatic toll booths, and some
gas stations have EMI fields
which may interfere with the
RKE transmitter.
If moving the transmitter to
different locations within the
vehicle does not help, place the
transmitter in the glove box
transmitter pocket with the
buttons facing to the right and
then press the START button.
.The vehicle's battery voltage is
low. The battery voltage must be
above 10 volts for the RKE
transmitter to be detected
properly.
NO FOB - OFF OR RUN?
This message displays when the
RKE transmitter is not detected
inside the vehicle while you are
trying to turn the ignition off. The
vehicle may be near a strong radio
antenna signal causing the RKE
system to be jammed. The vehicle
will remain in ACCESSORY until the
vehicle is turned off or is restarted,
or five minutes has expired. If you
turn the ignition off and you cannot
find the RKE transmitter, you will not
be able to restart the vehicle. The
RKE transmitter needs to be inside
the vehicle in order for the vehicle to
start. SeeStarting the Engine on
page 9‑21 for more information.

2. To verify that the garage dooropener is a Fixed Code unit,
remove the battery cover on the
hand-held transmitter supplied
by the manufacturer of the
garage door opener motor.
If there is a row of dip switches
similar to the graphic above,
the garage door opener is a
Fixed Code unit. If you do not
see a row of dip switches,
return to the previous section,
“Programming Universal Home
Remote –Rolling Code.” The hand-held transmitter can
have between eight and
12 dip switches depending on
the brand of transmitter.
The garage door opener receiver
(motor head unit) could also
have a row of dip switches that
can be used when programming
the Universal Home Remote.
If the total number of switches
on the motor head and
hand-held transmitter is different,
or if the dip switch settings are
different, use the dip switch
settings on the motor head unit
to program the Universal Home
Remote. The motor head dip
switch settings can also be used
when the original hand-held
transmitter is not available.

Battery Power Protection
This vehicle has a feature to help

lamps are left on: the underhood
lamp, if your vehicle has this
feature, vanity mirror lamps, cargo
lamps, reading lamps, console,
or glove box lamps. If any of these
lamps are left on, they will
automatically time-out after about10 minutes. To reset it, all of the
above lamps must be turned off or
the ignition key on.
Exterior Lighting Battery
Saver
If the manual parking lamps or
headlamps have been left on, the
exterior lamps will turn off as soon
as the ignition is turned off or
Retained Accessory Power (RAP) is
active. This protects against
draining the battery in case you
have accidentally left the headlamps
or parking lamps on. The battery
saver does not work if the
headlamps are turned on after the
ignition switch is turned to off.
If you need to leave the lamps on,
use the exterior lamp control to turn
the lamps back on.

Infotainment System 7-11
FM Stereo
FM signals only reach about
16 to 65 km (10 to 40 mi). Although
the radio has a built-in electronic
circuit that automatically works to
reduce interference, some static
can occur, especially around tall
buildings or hills, causing the
sound to fade in and out.
XM™Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from coast to
coast in the 48 contiguous United
States, and in Canada. Just as
with FM, tall buildings or hills can
interfere with satellite radio signals,
causing the sound to fade in and
out. In addition, traveling or standing
under heavy foliage, bridges,
garages, or tunnels may cause loss
of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on.
This interference causes an
increased level of static while
listening to the radio. If static is
received while listening to the
radio, unplug the cellular phone and
turn it off.
Diversity Antenna System
The AM-FM antenna is a hidden
self‐tuning system. It optimizes the
AM and FM signals relative to the
vehicle's position and radio station
source. No maintenance or
adjustments are needed.
Satellite Radio Antenna
For vehicles with XM Satellite Radio
Service, the antenna is located on
the roof or on the trunk lid of the
vehicle. Keep the antenna clear of
obstructions for clear radio
reception.
