Start motor assembly
1. SYSTEM DESCRIPTION
The starter (start motor) starts the engine with rotational power by converting the electric energy to the
mechanical energy.
When the engine is cranking, the pinion gear meshes with the ring gear. If the ring gear overruns, the
pinion gear clutch overruns to protect the pinion gear.

6) Normal Cancellation of the Cruise Control
The cruise control system will be canceled when one or more items of the following conditions are
applied;
When the brake pedal is depressed.
When the cruising speed is downed less than 38 km/h.
When pushing the ON-OFF switch of the cruise control lever.
When ESP is activated.
When applying the parking brake when driving.
When using the clutch in order to shift (M/T only).
And the cruise control system can be operated again in driving state. 1.

1) Overview
Dual mass flywheel (DMF)
- Manual transaxleDrive plate
- Automatic transaxle
Dual mass flywheel reduces the unbalanced
rotation of crankshaft in manual transaxle
equipped vehicle. The flywheel is installed on the
crankshaft and is engaged to the clutch disc to
transfer the driving torque from the engine to the
powertrain system. Additionally, DMF decreases
the rattling noise in transaxle and the vehicle
vibration by reducing the differences of torque and
rotational speed due to the combustion in engine.The drive plate initially drives the powertrain
system by using the power from the start motor
when starting the engine. The drive plate is
installed on the crankshaft and is engaged to the
torque converter of automatic transaxle to transfer
the driving torque from the engine to the powertrain
system.

2) Operation of DMF
Compensating the irregular operation of engine: The secondary flywheel operates almost evenly so
does not cause gear noises
The mass of the primary flywheel is less than conventional flywheel so the engine irregularity
increases more (less pulsation absorbing effect).
Transaxle protection function: Reduces the torsional vibration to powertrain (transaxle) by reducing
the irregularity of engine. -
