Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Auto-Start-Stop System
The Auto-start-stop system helps reduce fuel consumption by automatically shutting off the vehicle's engine while the vehicle is at a complete stop and restarting the engine when the brake pedal is released. The system can be disabled through the auto-start-stop control switch on the instrument panel centerstack. The Auto-start-stop system is automatically enabled whenever the ignition is turned on.
The engine automatically restarts when:
- the brake pedal is released.
- the Auto-start-stop system is disabled through the auto-start-stop control switch on the instrument panel centerstack.
- the battery has a low state of charge.
- it is necessary to maintain interior comfort.
- the blower fan speed is increased or the climate control temperature is changed.
- an electrical accessory is turned on or plugged in.
- there is low brake vacuum.
The Auto-start-stop system may not turn the engine off under these conditions:
- the HVAC system is in A/C, heat or defrost modes.
- the defroster is on.
- the battery has a low state of charge.
- the battery temperature is below 5°C (41°F) or above 60°C (140°F).
- the engine temperature is below 46°C (115°F).
- the engine temperature is below 60°C (140°F) and the HVAC system is in heat mode.
- the gear selector is not in Drive or Sport Mode.
- the steering wheel is turned rapidly or is at a sharp angle.
- vehicle speed of greater than 4 km/h (2.5 mph) for more than 2 seconds has not occurred.
