Road or Roller Testing
			
	      
			CAUTION: If road testing, check the brake
operation while still traveling at low speed
before continuing with the test. If the
brakes pull to one side, or appear to be
otherwise faulty, do not continue with the
road test until the fault has been found and
rectified.
During the road or roller test, check:
	- that the clutch pedal operation is not stiff or
	heavy.
 
	- that the initial gear engagement is smooth and
	there is no evidence of clutch drag.
 
	- that the parking brake control operates smoothly
	and releases quickly and completely.
 
	- that the clutch takes up the drive smoothly,
	without slip or judder.
 
	- that gear changing is smooth with no abnormal
	noises or vibrations from the transmission.
 
	- the engine power output is satisfactory, full
	power is achieved, acceleration is smooth and
	pedal operation is not stiff or heavy, and engine
	speed returns to idle correctly.
 
	- there is no excessive or abnormally colored
	smoke from the engine under normal driving,
	heavy load or overrun conditions.
 
	- that steering operation, including power steering
	(if equipped), is smooth, accurate, not
	excessively heavy or with excessive free play
	or vibration.
 
	- that the steering does not pull to one side and
	self centers smoothly after cornering.
 
	- that the speedometer, coolant temperature
	gauge and tachometer (if equipped) register the
	correct readings and operate correctly.
 
	- that the switches and controls operate smoothly
	and positively, warning and indicator lamps
	operate correctly and the direction indicator
	control self cancels when the steering is
	returned to the straight ahead position.
 
	- that the heating and ventilation systems operate
	correctly and effectively.
 
	- the brake operation and efficiency.
