First, check your vehicle’s owner’s manual to see if there are any scheduled maintenance items that need to be taken care of. Next, check all of your fluid levels, including engine oil, coolant, power steering fluid, brake fluid, and transmission fluid. If any of these are low, top them off before taking your car in. Lastly, take a look at your tires. Check the tread depth and tire pressure to make sure they are within the manufacturer’s recommendations.
