REMEDY FOR A DISCHARGED BATTERY

M1272005100023

Battery cable
for AYC

Battery fuse assembly

When the engine is started using a booster cable 
where the battery has completely run down and you 
attempt to start the vehicle without waiting for the 
battery to recover a certain charge, the engine can 
misfire and you just cannot start to move it. In such 
cases, charge the battery sufficiently; or, remove the 
AYC battery cable from the battery fuse assembly to 
make AYC inactive before attempting to start the 
vehicles. When the battery cable is removed, the 
ACD mode indicator lamp lights up. After the battery 
has been recharged, fit the battery cable back again 
and start the engine to ensure that the ACD mode 
indicator lamp is off.
