Myth: The start/stop button on the dash will not turn off my Prius while it’s running.
Fact: On early to 2010 models with a push-button smart key system, pushing and holding the button on the dash for about three seconds will shut off the ignition system on the vehicle – even if it’s in gear and moving along the roadway. Newer models may have different control logic – you only have to press the button briefly to shut down the vehicle. Check your Owner’s Manual for details on your vehicle’s system.
Myth: The brake system on my Toyota Prius is not able to stop the car at speed with a wide-open throttle condition.
Fact: The brake system on each Toyota model is capable of overpowering the driveline to stop the vehicle – even with the throttle in a wide-open condition. Apply firm, steady pressure on the brake pedal – use two feet if needed, to bring the vehicle to a halt. Do not pump the brakes in these conditions, as this may overheat the system, causing a reduction in brake performance. Prius is equipped with a combination of hydraulic and electric regenerative brake systems. All Prius vehicles have a brake system program that reduces gasoline engine power if both the throttle and brake pedals are depressed at the same time. This feature helps reduce the chance of damage to the hybrid system transmission in the event of simultaneous brake and throttle pedal application by the driver, and also helps to slow the vehicle under these circumstances. The regenerative braking via the main electric motor will continue to function to help slow the vehicle
Myth: In the event you encounter a runaway vehicle, the first thing you should do is to turn off the ignition.
Fact: Although turning off the ignition is a possible course of action, the first thing a driver should do is to put the transmission in Neutral. This separates the driveline from the wheels, and gives the driver instant speed control over the vehicle, and allows the driver time to assess what is happening. This also allows continued use of the power steering and brake systems for an easier stopping operation. Pressing the start/stop button to turn off the ignition can be done as a next step. This will shut down power assist to the brakes and steering system – reducing their performance, but the driver can still brake and steer the vehicle manually in this condition. The steering column on Prius will not lock up when the ignition is turned off while the vehicle is moving – allowing the driver steering control. Traditional key type ignitions systems can be turned off while the vehicle is moving without locking the steering column – as long as the key is left in the ignition. Removal of the key may result in a locked steering column, and hamper driver steering control. After placing the transmission in Neutral, and the vehicle is brought to a stop at the side of the road, the final step should be to turn of the ignition.
Myth: The parking brake is effective in stopping a vehicle at speed.
Fact: The parking brake may be helpful in that it can provide some additional brakeforce. However, the amount of brakeforce the parking brake applies will be negligible in a vehicle that is running at anything over paring lot speeds. Placing the transmission in Neutral and using firm steady pressure on the brake pedal will be the best way to bring the vehicle to a stop.
Myth: The transmission would not go into Neutral when an attempt was made to put it in Neutral.
Fact: Prius does have an electronic link between the shift lever and the transmission. The driver should place the Prius in Neutral by moving the shift lever to the “N” position – to the left side of the shift gate, and hold it there for a second – this will put the Prius transmission in Neutral. Firm application of the brakes will slow the vehicle down. Pressing and holding the start/stop button can be used as a final action to stop the vehicle if needed.
