The vehicle comes with two transmitters. Each

numbers correspond to the driver of the vehicle. For
example, the memory seat position for driver 1 will be
recalled when using the transmitter labeled “1”,
if enabled through the DIC. See Memory Seat, Mirrors,
and Pedals on page 2‑8 and DIC Vehicle
Customization (With DIC Buttons) on page 4‑76 for
more information.
Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to this vehicle will
work. If a transmitter is lost or stolen, a replacement can
be purchased and programmed through your dealer.
When the replacement transmitter is programmed to
this vehicle, all remaining transmitters must also be
reprogrammed. Any lost or stolen transmitters will no
longer work once the new transmitter is programmed.
Each vehicle can have up to eight transmitters
programmed to it. See “Relearn Remote Key” under
DIC Operation and Displays (With DIC Buttons) on
page 4‑50 or DIC Operation and Displays (Without DIC
Buttons) on page 4‑59 for instructions on how to match
RKE transmitters to your vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” under DIC
Warnings and Messages on page 4‑66 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.
