WARNING:
When you are doing this inspection, the vehicle
could move suddenly. If the vehicle moves, you or

Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts.
3. For automatic transmission vehicles, try to start the engine in each gear. The starter should work only in P (Park) or N (Neutral). If the starter works in any other position, your vehicle needs service.
For manual transmission vehicles, put the shift lever in Neutral, push the clutch pedal down halfway, and try to start the engine.
