If equipped, memory seats allow two drivers to save and recall their unique seat positions for driving the vehicle, and a shared exit position for getting out of the vehicle. Other feature positions may also be saved, such as power mirrors,

if equipped. Memory positions are linked to RKE transmitter 1 or 2 for automatic memory recalls.

Before saving, adjust all available memory feature positions. Turn the ignition on and then press and release SET; a beep will sound.

Then immediately press and hold 1,

2, or B (Exit) until two beeps sound. To manually recall these positions, press and hold 1, 2, or B until the saved position is reached. Follow the instructions under “Saving Memory Positions.”

The vehicle identifies the current driver’s RKE transmitter number (1–8). See Remote Keyless Entry (RKE) System Operation (Keyless Access) 0 34 or

42. Only RKE transmitters 1 and 2 can be used for automatic memory recalls. A Driver Information Center (DIC) welcome message indicating the transmitter number may display for the first few ignition cycles following a transmitter change. For Seat Entry Memory to work properly, save the positions to the memory button (1 or 2) matching the RKE transmitter number displayed in the DIC welcome message. Carry the linked RKE transmitter when entering the vehicle.

Memory adjustments may not be available upon delivery or after service until steps in “Saving Memory Positions” section are performed.

Identifying Driver Number

To identify the driver number:

Start the vehicle with a different key or RKE transmitter. The DIC should display the driver number; 1 or 2. Turn the ignition off and remove the key or RKE transmitter from the vehicle.

Start the vehicle with the initial key or RKE transmitter. The DIC should display the other driver number not shown in Step 1.

Saving Memory Positions

To save preferred driving positions 1 and 2:

Turn the ignition on or to ACC/ ACCESSORY.

Adjust all available memory features to the desired driving position.

Press and release SET; a beep will sound.

Immediately press and hold the 1 or 2 memory button matching the above DIC welcome message until two beeps sound.

If too much time passes between releasing SET and pressing 1, the memory position will not be saved and two beeps will not sound.

Repeat Steps 3 and 4.

1 or 2 corresponds to the driver number. See “Identifying Driver Number” previously in this section.

Repeat Steps 1–4 for a second driver using 1 or 2.

To save the position for B and Seat Exit Memory, repeat Steps 1–4 using B. This saves the position for getting out of the vehicle.
