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 keyless
access 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 keyless access transmitter. Do not carry
the keyless access 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 elds which may
interfere with the keyless access transmitter.
If moving the transmitter
to different locations
within the vehicle does
not help, place the
transmitter in the center
console transmitter
pocket with the buttons
facing forward and
then press the
START button.
The vehicle’s battery voltage is low. The
battery voltage must be above 10 volts for
the keyless access transmitter to be
