If by use you mean disengage by depressing the clutch pedal , then it's because it is difficult for the starter to turn over the engine when the car is in gear. Also, it's a safety issue, because if the car is in gear when you start it, it could lurch forward, causing an accident. Either the car must be in neutral or the clutch must be disengaged. Even cars with automatic transmissions won't start unless the gear-select lever is in Park or Neutral. Some cars with automatic transmissions even require the driver's foot to be on the brake for the car to start.
A stick shift with a clutch
If it has a stick shift and clutch, it is standard. If no clutch and stick shift, it is an automatic.
Safest way: Set Parking brake Push clutch pedal to the floor Shift to neutral Turn key to start
No. You will stall(or cut-out). This means that the car shuts down and then you have to clutch in and put it into neutral. Then(still on the clutch) turn on the car again.
A clutch cable is a cable that is connected from a foot petal inside a car to the transmission. It is necessary for a person to change gears in a standred transmission car or truck.
That would be a standard transmission.
You can push start a car with a standard transmission. Place the car in neutral. Push the car to a brisk speed. Mash down the clutch pedal and place the gear selector in 2nd gear. Pop the clutch, and it should start.
Push the clutch all the way to the floor, and turn the key to start it.
Does it turn over? Does it turn over?
because you did not step on your clutch pedal
If the tracker is a "standard shift" not automatic transmission. You could pop start the engine by putting the car in 1st gear, with the clutch pedal down and the ignition on. Roll the car and once car is rolling release clutch pedal. Vehicle should start, hope this is what you ment by "manually".
