DISCHARGED BATTERY
M1352003500064
The ABS system consumes a large amount of battery current
for its self-check function. If the battery is completely
discharged and booster cables are used to start the engine, the
engine must be allowed to idle for a few minutes to recharge. If
the battery does not recharge, the engine may misfire or stall.
To prevent this condition,
•
allow the engine to idle for a few minutes before driving the
vehicle, or
NO.
