ORLANDO, Fla., (October 27, 2014) – Worn tires can send a car into dangerous skids and spins on wet and icy winter roads. Checking tire pressure and tread depth monthly can help motorists keep tires in optimal condition, according to AAA.

“The two most important tire safety checks – a pressure reading and tread depth measurement – are very simple to do,” according to Greg Brannon, AAA’s director of Automotive Engineering. “If motorists spend about two minutes on each tire, they will keep their tires at peak performance.”

Monthly tire checks take two steps:

  • Measure tread depth with a quarter rather than a penny. When the top of Washington’s head is exposed, the tread depth is 4/32″ or less and it’s time to start shopping for new tires.
  • Use a quality gauge to check tire pressure. For proper results, make sure tires are cold. Look for the recommended air pressure in the vehicle’s owner’s manual the tire information decal located inside the driver’s side door or in the glove compartment. The number molded into the tire sidewall is not recommended for normal operating condition; this specification is for a tire that is carrying its maximum rated payload.

“Worn tires should be replaced immediately because they significantly impact safety,” says Brannon. “Testing has shown that tires with only half of their tread depth can take up 6 feet longer to stop from 40 miles-per-hour on a wet surface, even with the antilock braking system engaged.”

Heather HunterAAA suggests motorists mark November 2 for key winter car care checks

ORLANDO, Fla., (October 20, 2014) – Consumers have leveraged the changing of the clocks to remember important but infrequent tasks like replacing smoke alarm batteries. AAA suggests motorists also use this event as a reminder to check their vehicle for winter readiness.

“The end of daylight savings time means that winter weather is on the way, which can be rough on your car,” says AAA’s director of Automotive Engineering, Greg Brannon. “This is a good time to have vehicle systems checked and perform important maintenance to ensure your car is in peak condition.”

Harsh winter conditions make your vehicle work harder, particularly the charging and starting system, headlights, tires and windshield wipers. AAA recommends that motorists:

  • Clean any corrosion from battery posts and cable connections and wash all surfaces with battery terminal cleaner or a solution of baking soda and water. Have the battery checked by a professional to ensure it is strong enough to face cold weather.
  • Have any engine drivability problems corrected at a good repair shop. Symptoms like hard starts, rough idling, stalling or diminished power could signal a problem that would be exacerbated by cold weather.
  • Replace worn windshield-wiper blades. If your climate is harsh, purchase one-piece beam-type or rubber-clad “winter” blades to fight snow and ice build-up. Use cold-weather windshield washer solvent and carry an ice-scraper.
  • Inspect all lights and bulbs and replace burned out bulbs. Clean road grime or clouding from all lenses.
  • Have your mechanic check the exhaust system for leaks and look for any holes in the trunk and floorboards.
  • Examine tires for tread depth, uneven wearing and cupping. Check tire pressures once a month when tires are cold, before driving for any distance. In extreme climates, a set of winter snow tires may be a wise investment.

  • Service intervals for oil changes, brake, transmission and power steering fluids and coolant have increased with advances in technology.
  • Monthly safety checks are critical for detecting issues that could lead to a hazardous situation or major repair.

Additional Materials

ORLANDO, Fla., (October 14, 2014) – New fluid technologies and engine designs have combined to reduce the burden of properly maintaining today’s vehicles. Fewer trips to the repair facility, however, may put motorists at risk of missing clues that could head off safety issues or expensive repairs.

“Every vehicle has a unique maintenance schedule, but many automakers are extending service intervals for vehicle fluids,” says John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “Less maintenance improves the cost of vehicle ownership, but fewer visits to the repair facility means the technician will have fewer opportunities to check your vehicle for signs of wear. It’s important for motorists to conduct monthly safety inspections to identify issues before they escalate.”

Examples of new fluid service intervals include:

  • Oil: Cars today are designed to travel at least 5,000 miles between oil changes, and many newer models can be driven up to 7,500 miles or more before an oil change is necessary. Some vehicles that use full-synthetic engine oils have service intervals approaching 15,000 miles.  Be sure to check your oil level, either under the hood or through the vehicle’s onboard computer system.
  • Coolant: Requirements for flushing the coolant can vary from every two years to more than 100,000 miles, depending on the coolant type used. However, be sure coolant levels are correct as leaks in the system could cause major issues.
  • Brake fluid:  Most vehicle manufacturers recommend that brake fluid be replaced periodically to flush moisture and contaminants from the system. Check your vehicle owner’s manual for specific recommendations. If not specified, AAA recommends flushing the brake system and replacing with new fluid every two years.
  • Transmission fluid: Modern automatic transmissions are increasingly being filled with “lifetime” fluids that do not need to be changed until the vehicle has traveled 100,000 miles or more. The owner’s manual or maintenance booklet is the definitive source for specific transmission fluid requirements.

A monthly, 10-minute vehicle inspection can highlight issues that need attention. Motorists should check the level of the engine oil, brake fluid, engine coolant, washer fluid and power steering fluid.  In addition, a check of the tire pressure and tread depth will help ensure safety on the road.

Heather HunterNew study reveals that lack of experience with advanced systems could put motorists at risk.

ORLANDO, Fla., (May 2, 2014) – Advanced driver assistance systems (ADAS) offer a significant opportunity to reduce collisions, improve traffic flow and enhance driver convenience. However, motorists may not fully understand the operation and limitations of these technologies. AAA’s research found that the assumptive gap poses a risk for distracted drivers. Although the adaptive cruise control and autonomous braking systems performed as described in the owner’s manuals, motorists unfamiliar with these devices may not be prepared for instances when the technology does not engage. The AAA research was conducted with the Automotive Research Center of the Auto Club of Southern California.

“There are significant benefits to this technology, but these systems have limitations, and multi-tasking drivers could be caught off guard by relying too heavily on safety features,” says John Nielsen, managing director, AAA Automotive Engineering and Repair. “The benefits of these systems could easily be outweighed if motorists are not familiar with their operation or lessen focus behind the wheel. Technology is not a substitute for an alert, engaged driver.”

The National Highway Traffic Safety Administration’s New Car Assessment Program highlights crash-avoidance technologies “to help consumers buy a safer car.” These systems can alert a driver to a potential crash, adjust the vehicle’s pace to maintain a pre-set speed, and even brake independently to avoid a collision. Automakers are ramping up ADAS deployment to maximize safety benefits, increasing motorist exposure to autonomous systems.

To better understand how adaptive cruise control and autonomous braking function, AAA conducted test-track simulations consisting of a variety of typical commuting scenarios. Overall, the simulations demonstrated that adaptive cruise control did a good job of maintaining a specified following distance when traveling behind slower-moving vehicles in a highway setting. However, autonomous braking systems did not always recognize obstacles, provide a warning signal or engage the brakes to slow or stop the vehicle.  AAA’s research team also observed that:

  • Adaptive cruise control systems performed best when following more closely than AAA’s recommended three-second rule.
  • Tracking a vehicle at highway speeds while navigating a mild curve was unexpectedly difficult, but improved when following distance was reduced.
  • The ability to recognize obstacles varied between vehicles. The owner’s manuals for these vehicles warn that the systems may not recognize or react to motorcycles, a stopped vehicle, traffic cones or other obstructions.

Automakers have noted system limitations in owner’s manuals; but there are many indications that motorists often do not fully read the manual. Television commercials highlight capabilities without any indication of system limitations, and that input is the primary source of motorist knowledge about what these systems can do. AAA suggests safety gaps could be reduced if:

  • Automakers enhance communication to make clear and obvious the limitations of these systems.
  • Motorists become thoroughly familiar with all the technology in their car including advanced driver assistance systems before operating the vehicle.
