Your vehicle may have this display. To access this
display, the vehicle must be in P (Park). If your vehicle
has the Tire Pressure Monitor System (TPMS), after
rotating the tires or after replacing a tire or sensor, the
system must re-learn the tire positions. To re-learn the
tire positions, see Tire Pressure Monitor System on
page 6 73. See Tire Inspection and Rotation on
page 6 78 and DIC Warnings and Messages on
page 4 61 for more information.
To access this display, the vehicle must be in P (Park).
This display allows you to match Remote Keyless
Entry (RKE) transmitters to your vehicle. This procedure
will erase all previously learned transmitters. Therefore,
they must be relearned as additional transmitters.

REMOTE KEY displays.

three seconds.

will display.
4-58

the first transmitter at the same time for about
15 seconds.
On vehicles with memory recall seats, the first
transmitter learned will match driver 1 and the
second will match driver 2.
A chime will sound indicating that the transmitter is
matched.
4. To match additional transmitters at this time, repeat
Step 3.
Each vehicle can have a maximum of eight
transmitters matched to it.
5. To exit the programming mode, you must cycle the
key to LOCK/OFF.
Your vehicle may have a compass in the Driver
Information Center (DIC).
