See Tire Pressure on page 9‑66 and Tire Messages on page 4‑48 for more information. Battery Voltage This display shows the current battery voltage. The vehicle's charging system regulates voltage based on the state of the battery. The battery voltage may fluctuate when viewing this information on the DIC. This is normal. If there is a problem with the battery charging system, the charging system light illuminates and/or the DIC displays a message. See Charging System Light on page 4‑23, Battery Voltage and Charging Messages on page 4‑37 and Battery Load Management on page 5‑6 for more information.

Change Compass Zone The vehicle may have this feature. To change the compass zone through the DIC, see "DIC Compass" later in this section. Relearn Remote Key If the vehicle has the Remote Keyless Entry (RKE) system, this display allows you to match the transmitter to the vehicle. This procedure will erase all previously learned transmitters. Therefore, they must be relearned as additional transmitters. If the vehicle has the keyless access system, see the Keyless Access information for Remote Keyless Entry (RKE) System Operation (Key Access) on page 1‑5 or Remote Keyless Entry 4-35 (RKE) System Operation (Keyless Access) on page 1‑7 for instructions on matching a keyless access transmitter to the vehicle. To match an RKE transmitter to the vehicle: 1. Press the vehicle information button until Press To Relearn Remote Key displays. 2. Press the set/reset button until Remote Key Learning Active is displayed. 3. Press and hold the lock and unlock buttons on 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 sounds indicating that the transmitter is matched.
