Always observe the following:
WARNING - Tire Inflation
Overinflation or underinflation can reduce tire life, adversely affect vehicle handling, and lead to sudden tire failure. This could result in loss of vehicle control and potential injury.
Tire care For proper maintenance, safety, and maximum fuel economy, you must always maintain recommended tire inflation pressures and stay within the load limits and weight distribution recommended for your vehicle.
Check your tires once a month or more. Also, check the tire pressure of the spare tire. How to check Use a good quality gauge to check tire pressure.
Park your car at the side of the road so that you can work with the Tire Mobility Kit away from moving traffic. To be sure your vehicle will not move, even when you're on fairly level ground, always set your parking brake. Only use the Tire Mobility Kit for sealing/inflation passenger car tires.
Turn the ignition switch to ACC so the steering wheel isn’t locked. Place the transmission shift lever in N (Neutral). Release the parking bake. Press the brake pedal with more force than normal since you will have reduced brake performance.
