The remote start feature on Chevy Suburban has many benefits. You can start your vehicle in advance when the weather is too hot or cold outside. The system turns on the air conditioning or heating, making inside cabin temperature more tolerable when you get to your vehicle.


Before you start your Suburban remotely, ensure that the vehicle is parked in a well ventilated area. Starting your vehicle in an enclosed space, like a closed garage, introduces risk of carbon monoxide poisoning.

Safety precautions

These are warnings against actions which may cause injury to people/vehicle if the warning is ignored.

  • Never start the engine of your Suburban in an enclosed area (such as a garage or indoor parking lot) where exhaust gases may accumulate and create a hazardous environment with potential for Carbon Monoxide (CO) poisoning.
  • Do not start the engine if a child or pet are present in or near the vehicle.
  • Always turn off vehicle systems such as the windshield wipers, headlights and radio before leaving the vehicle. If left on, such systems may be damaged or vehicle battery depleted by remote engine start in extreme cold weather.

Engine idling law

There are laws against car idling with no passenger or driver inside in many states to protect the environment.

So check with your local state laws before using the remote start feature on your Chevy Suburban.
