Display Item List
Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“-1”“-2”“OFF” can be selected by pressing the “UP”“DOWN” on CONSULT-III screen.
However, do not select mode other th an “0” and “OFF”. If the “+1” or “-1” or “-2” is selected, that
might cause the irregular driveability.
Check CVT Fluid Deterioration Date
CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.
SELF-DIAGNOSTIC RESULT MODE
After performing self-diagnosis, place check marks for results on the CVT-31, "How to Perform Trouble Diag-
nosis for Quick and Accurate Repair" . Reference pages are provided following the items.

ENGINE BRAKE ADJ. The engine brake level setting can be canceled.
CONFORM CVTF DETERIORTN The CVT fluid deterioration level can be checked.
“ENGINE BRAKE LEVEL”
0: Initial set value (Engine brake level control is ac-
tivated)
OFF: Engine brake level control is deactivated.
