AUTO STOP START

• Engine: After warming up, run en-

gine at idle.

• Selector lever position: P or N 

(CVT)

• Gear position: Neutral (M/T)
• Stop/Start OFF switch: ON (indi-

cator lamp is ON)

CAUTION:

Be careful so that a hood opera-
tions in the opened state when 
carry out the work.
NOTE:
Before performing this test, be sure 
to check that OK is displayed on 
BATTERY STATUS in DATA MONI-
TOR of IPDM E/R because this func-
tion may not be operate when the 
battery condition is not satisfied.

Stop/Start system operates nor-
mally. (Engine stop/Restart)
