Chevrolet Silverado: Starting and Operating / Stop/Start System

Chevrolet Silverado 2019-2025 Owners Manual / Driving and Operating / Starting and Operating / Stop/Start System

If equipped, the Stop/Start system will shut off the engine to help conserve fuel. It has components designed for the increased number of starts.

Warning

The automatic engine Stop/Start feature causes the engine to shut off while the vehicle is still on. Do not exit the vehicle before shifting to P (Park). The vehicle may restart and move unexpectedly. Always shift to P (Park), and then turn the ignition off before exiting the vehicle.

Auto Engine Stop/Start

When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displays AUTO STOP. See Tachometer. When the brake pedal is released or the accelerator pedal is pressed, the engine will restart.

To maintain vehicle performance, other conditions may cause the engine to automatically restart before the brake pedal is released.

Auto Stops may not occur and/or Auto Starts may occur because:

  • The climate control settings require the engine to be running to cool or heat the vehicle interior.
  • The vehicle battery charge is low.
  • The vehicle battery has recently been disconnected.
  • Minimum vehicle speed has not been reached since the last Auto Stop.
