Engine mechanismEngine assemblyInspection1. Check coolant.
2. Check engine oil.
3. Check battery.
4. Check air filter assembly.
5. Check spark plug [4G18-3705113].
6. Check drive belt [4G18-1307107].Hint: do not check belt tension, because automatic tensioner is applied.7. Check ignition timing.(a) Warm up engine.
(b) Connect timing lamp to engine.
(c) Check ignition timing at idle speed.
Ignition timing: before top dead center Note: when checking ignition timing, place
transmission at neutral position.
Hint: After run the engine for 5 seconds with rotating
speed of 1000-1300rpm, check the engine could
recover to idle running.8. Check engine idle speed.(a) Warm up engine and run it at idle speed.
(b) Read engine rotating number in data flow with diagnostic instrument.
(c) Check idle speed.
Idle speed: about 750-850rpm
Notes:When checking idle speed, place cooling fan at OFF position.Turn off all auxiliary devices and air conditioner.Engine mechanism - Engine assemblyK-line 26

Note
1. Notes that are necessary for steering system:
(a) It is necessary to change parts correctly, for they will influence the performance of steering system to
make running danger.
2. Notes that are necessary for SRS airbag:
(a) MR7180 assembles with SRS (auxiliary protection system) such as safety airbag at the side of driver
and safety airbag at the side of passenger.
Maintenance does not accord with correct repair step, this might incur SRS explodes suddenly in
repair term to make heavy accident. Before repairing auxiliary protection system (including
disassembling, assembling, check or change parts), it is necessary to read the notes in SRS chapter
(auxiliary protection system).
