into the tire sidewall. Recommended tire pressures can be found

the front and rear tires. While checking the tire
pressures—including the spare—drivers also should inspect the
tire treads for adequate depth and any signs of uneven wear that

Fluids during Extreme Heat Too Engine fluids are essential to
keeping a vehicle running smoothly. Most fluids not only
lubricate, they also serve as coolants by helping carry heat
away from critical components. When fluid levels are low, this
cooling effect is reduced, and the possibility of overheating
increases. Drivers to should check all vehicle fluids including
motor oil, transmission fluid, power steering fluid an
