TO DEFOG YOUR WINDSHIELD

A fogged-up windshield is easy to correct with the proper settings. For best results, clear all snow and ice from the windshield and rear window. 
  1. Press the Defog/Defrost button. Or, if equipped, press the Max Defrost button. 
  2. Turn off the Recirculation button if it’s on. 
  3. Press the Sync button (if equipped). 
  4. Set the fan to the highest setting. 
  5. If defrosting, set the temperature to High (automatic system) or Full Hot (manual system). 
  6. If defogging, turn the A/C to On. 
  7. Once the windshield is clear, revert to your desired settings. 

To maintain a clear windshield, turn off the Recirculation button, select Airflow Distribution to the windshield and floor, set the Fan to a medium setting and the Temperature to a warmer setting.

Q&As

WHEN SHOULD I HAVE MY TIRES ROTATED?

As part of a newly revised maintenance schedule, owners of 2011 model year or newer GM vehicles are advised to see their dealer for a tire rotation every 7,500 miles.

HOW DO I PROPERLY STORE TIRES?

Tires age when the vehicle remains parked for extended periods of time. If a vehicle will be stored for a month or more, park it in a cool, dry and clean area away from direct sunlight to slow the aging process. The area should be free of grease, gasoline or other substances that can deteriorate rubber. This also applies to unmounted tires.

Parking for an extended period can also cause flat spots that may result in vibrations while driving. When storing a vehicle for more than a month, remove the tires or raise the vehicle to reduce the weight from the tires.

DO I NEED A WHEEL ALIGNMENT?

Proper wheel alignment is key to the life of your tires. If your vehicle is misaligned, it can cause your tires to wear unevenly, and you may experience handling problems such as pulling or abnormal vibration.

Tires and wheels are aligned and balanced at the factory to help provide best overall performance. Adjustments to wheel alignment and tire balancing are not necessary on a regular basis. Consider a wheel alignment check if there is unusual tire wear or if your GMC vehicle is significantly pulling to one side or the other.

A tire that is out of balance often affects ride quality and can shorten the life of tires, bearings, shocks and other suspension components. If the vehicle is vibrating when driving on a smooth road, the tires and wheels may need to be rebalanced.
