Thereare a number of precautions you can take to help minimizeheat and other factors that negatively affect clutch life, such as:START IN THE PROPER GEARThe right starting gear can change based on your load, but as a general rule: select thegear combination that lets you take up the slack and start moving out with an idlingengine, or if necessary, that creates just enough throttle to prevent stalling the engine.SHIFT TO THE RIGHT GEARFocus on vehicle speed instead of engine speed when deciding to shift gears. Skipshifting or choosing too high a gear can cause the clutch to generate excessive heat.DON’T RIDE THE CLUTCH OR COASTDon’t leave the clutch pedal engaged while at a stop and alternatively, don’t release theclutch when the transmission is in gear while coasting in traffic.
