NOTES
1. The engine speed may be 20 to 100 RPM lower than indicated above for a new vehicle [driven approximately 500 km (300 miles) or less],
but no adjustment is necessary.
2. If the engine stalls or the RPM is low even though the vehicle has been driven approximately 500 km (300 miles) or more, it is probable
that deposits are adhered to the throttle valve, so clean it.
