Vehicle Care For additional information regarding how much weight the vehicle can carry, and an example of the Tire and Loading Information label, see Vehicle Load Limits on page 9‑20. How the vehicle is loaded affects vehicle handling and ride comfort. Never load the vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Do not forget the spare tire. If the vehicle has a compact spare tire, it should be at 60 psi (420 kPa). See Compact Spare Tire on page 10‑82 and Full-Size Spare Tire on page 10‑83 for additional information. How to Check Use a good quality pocket-type gauge to check tire pressure. Proper tire inflation cannot be determined by looking at the tire. Check the tire inflation pressure when the tires are cold, meaning the vehicle has not been driven for at least three hours or no more than 1.6 km (1 mi). Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. 10-53 If the inflation pressure is low, add air until the recommended pressure is reached. If the inflation pressure is high, press on the metal stem in the center of the tire valve to release air Re-check the tire pressure with the tire gauge. Return the valve caps on the valve stems to prevent leaks and keep out dirt and moisture.
