Driving To start the vehicle: 1. Make sure the parking brake is fully set. 2. Press the clutch pedal to the floor, then put the gearshift lever in the neutral position. 3. Start the engine. 4. Press the brake pedal and move the gearshift lever to the desired gear; 1 (First) or R (Reverse). 5. Release the parking brake, then slowly release the clutch pedal while slowly pressing on the accelerator. During each shift, the clutch pedal must be fully depressed to the floor. Failure to fully depress the clutch pedal to the floor may cause increased shift efforts, prematurely wear transmission components or damage the transmission. Make sure the floor mat is properly positioned so it doesn't interfere with the full extension of the clutch pedal. Do not drive with your foot resting on the clutch pedal or use the clutch pedal to hold your vehicle at a standstill while waiting on a hill. These actions will reduce the life of the clutch. Recommended shift speeds Do not overspeed the engine when going downhill or steep grades. If equipped, use the tachometer and do not allow engine speed to exceed the redline area. Operating the engine beyond the recommended speeds can cause severe engine damage.
