• Perform with the vehicle in an unloaded condition (no occupants; spare tire, jack and tools are in designated positions.)
Note
• The auto leveling system initialization is implemented only on vehicles without the front auto leveling sensor.
• If the following servicing is to be done, perform the procedure for the case where system initialization has never been done. (See
Initialization Has Never Been Performed.)
― Procedure for changing vehicle height is performed such as changing suspension.
― Initialized auto leveling control module is installed
Initialization Has Never Been Performed
Caution
• Perform the procedures in Steps 3 to 5 within 30 s.
1.Turn the ignition switch to the LOCK position.
2.Set a jumper wire to the DLC-2 terminal B.

Caution
• If the terminals are mistakenly connected, vehicle damage or fire could occur. When connecting with the jumper wire, thoroughly verify what terminals are being connected to prevent a miss-connection.
3.Turn the ignition switch to the ON position.
4.Verify that the headlight auto leveling warning light flashes every 0.25 s.

5.Ground the DLC-2 terminal B 3 times or more at 1 s intervals using the jumper wire.
6.After the headlight auto leveling warning light flashes three times at 0.25 s intervals, verify that it turns off.
• If the headlight auto leveling warning light continues to flash at 0.25 s intervals, perform a DTC inspection, as there could be a malfunction in the auto leveling system. (See
DTC INSPECTION [HEADLIGHT AUTO LEVELING SYSTEM].) Repair or replace the malfunctioning area, then repeat the procedure from Step 1.
7.Verify that the motor inside the headlight leveling actuator operates and the headlight optical axis lowers from its current position and returns to its original position.
• If the motor inside the headlight leveling actuator does not operate, the headlight optical axis may be at the bottommost position, or the procedure may have been performed incorrectly. Therefore, park the vehicle on level ground and resume the procedure from Step 1.
8.Disconnect the jumper wire from DLC-2.
9.Verify that the headlight auto leveling warning light is not illuminated.

• Perform the procedures in Steps 6 to 7 within 5 s.
1.Turn the ignition switch to the LOCK position.
2.Turn on the headlights TNS position.
3.Set a jumper wire to the DLC-2 terminal B.

10.Pull out the jumper wire from DLC-2.
11.Verify that the headlight auto leveling warning light is not illuminated.
