Chevrolet 2004 Avalanche Owner's Manual page 161

To store the memory settings, do the following:
1. Adjust the driver's seat (including the seatback
recliner, lumbar, and side wing area), throttle
and brake pedals, both of the outside mirrors, and
the radio station presets to your preference.
2. Press and hold the 1 or 2 (for driver 1 or 2) button
of the memory control for three seconds. A double
chime will sound to let you know that the position
has been stored.
To repeat the procedure for a second driver, follow the
preceding steps, but press the other numbered
memory control button.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), a single chime will sound and
the memory position will be recalled.
If you use the unlock button on the remote keyless entry
transmitter to enter your vehicle, the preset driver's
seat, throttle and brake pedal, mirror positions, radio
station presets and the last choosen climate control
settings will be recalled if programmed to do so through
the Driver Information Center (DIC). See DIC Operation
and Displays on page 3-50. The numbers on the
back of the transmitters, 1 or 2, correspond to the
numbers on the memory controls.
The seat, throttle and brake pedals and mirror positions
can also be recalled when placing the key in the
ignition if programmed to do so through the Driver
Information Center (DIC). See DIC Operation and
Displays on page 3-50.
To stop recall movement of the memory seat feature at
any time, press one of the memory buttons or power
seat controls.
