If you have additional transmitters to program, this
process can be repeated until four transmitters have been
programmed. The DIC will then display MAX # FOBS
LEARNED and will exit the programming mode.
When you are done programming transmitters, press
the unlock button on each keyless access transmitter
twice. After performing this process, transmitters
previously programmed will no longer work with your
vehicle and must be reprogrammed.
Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery. The DIC
may display KEY FOB BATTERY LOW.
A weak battery may also cause the DIC to display
NO FOBS DETECTED when you try to start the vehicle.
If this happens, place the transmitter in the console
bin transmitter pocket with the buttons facing to the
front of the vehicle. Then, with the vehicle in PARK (P)
or NEUTRAL (N), press the brake pedal and the
start button. SeeStarting the Engine on page 2-24,
for additional information about your vehicle’s
electronic keyless ignition with push button start.Although this will start the vehicle, it is recommended
that you replace the transmitter battery as soon as
possible.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
To replace the battery, do the following:
1. Insert a coin or similar object into the slot on the
back of the transmitter and carefully pry apart the
front and back.
2. Carefully pull the battery out of the transmitter.

Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot on the brake pedal, press the
START button. If no keyless access transmitter
is present, the DIC will display NO FOB
DETECTED. When the engine begins cranking, let
go of the button. The idle speed will go down as
your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY
LOW. You can still drive the vehicle. See “Battery
Replacement” underKeyless Access System
Operation on page 2-4for more information.Notice:Holding the button in for longer than
15 seconds at a time will cause the vehicle’s battery
to be drained much sooner. This can also cause
damage to the starter motor. Wait 15 seconds
between each try to avoid draining your vehicle’s
battery or damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
Stopping Your Engine
Move the shift lever to PARK (P) and press the
OFF/ACCESSORY button. If the shifter is not in
PARK (P), the vehicle will go into accessory mode
and the DIC will display SHIFT TO PARK. Once the
shifter is moved to PARK (P), the vehicle will turn off.
If the keyless access transmitter is not detected
while going to off, the DIC will display NO FOB – OFF
OR RUN?.
