Owner’s Manuals 2023 Stop/Start System — If Equipped

Stop/Start System — If Equipped

The Stop/Start function is designed to reduce fuel consumption. The system will stop the engine automatically during a vehicle stop if the required conditions are met. Releasing the brake pedal, pressing the accelerator pedal or shifting out of DRIVE (D) will automatically re-start the engine.

This vehicle has been upgraded with a heavy-duty starter, enhanced battery, and other upgraded engine parts to handle the additional engine starts.

AUTOSTOP MODE

The Stop/Start feature is enabled after every driver key start. At that time, the system will go into STOP/START READY and if all other conditions are met, can go into a STOP/START AUTOSTOP ACTIVE.

To Activate Auto STOP/START, The Following Must Occur:

  • The system must be in STOP/START READY state. A STOP/START READY message will be displayed in the instrument cluster within the Stop/Start section "⇨WARNING LIGHTS AND MESSAGES".

  • The vehicle must be completely stopped.

  • The gear selector must be in a forward gear and the brake pedal pressed.

The engine will shut down, the tachometer will move to the zero position and the Stop/Start telltale will illuminate indicating you are in Autostop. Customer settings will be maintained throughout the Auto Stop/Start process.

POSSIBLE REASONS THE ENGINE DOES NOT AUTOSTOP

Prior to engine shut down, the system will check many safety and comfort conditions for Stop/Start and ensure they are fulfilled. Detailed information about the operation of the Stop/Start system may be viewed in the instrument cluster display Stop/Start screen. Situations when the engine will not stop include (but not limited to):

  • If Stop/Start is manually disabled by the Stop/Start OFF button.

  • Driver’s seat belt is not buckled.

  • Driver’s door is not closed.

  • Battery temperature is too warm or cold.

  • Battery charge is low. During this time a message will display “Stop/Start Not Ready Battery Charging”.

  • The vehicle is on a steep grade.

  • Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved.

  • HVAC is set to full defrost mode at a high blower speed.

  • HVAC is set to MAX A/C.

  • Engine has not reached normal operating temperature.

  • The transmission is not in a forward gear.

  • Hood is open.

  • Brake pedal is not pressed with sufficient pressure.

  • Accelerator pedal input.

  • Engine temperature is too high.

  • 5 mph (8 km/h) threshold has not been achieved from previous Autostop.

  • Steering angle is beyond threshold.

  • Vehicle is at too high of an altitude.

  • Ambient temperature is beyond operating range.

  • Stop/Start related system malfunction.

  • Adaptive Cruise Control (ACC) is on and speed is set.

It may be possible for the vehicle to be driven several times without the Stop/Start system going into a STOP/START READY state under more extreme conditions of the items listed.

TO START THE ENGINE WHILE IN AUTOSTOP

While in a forward gear, the engine will start when the brake pedal is released or the accelerator pedal is pressed. The transmission will automatically re-engage upon engine restart.

Conditions That Will Cause The Engine To Start Automatically While In Autostop:

  • The transmission selector is moved out of DRIVE.

  • To maintain cabin temperature comfort.

  • HVAC is set to full defrost mode.

  • HVAC system temperature or fan speed is manually adjusted.

  • Battery voltage drops too low. During this time a message will display “Stop/Start Not Ready Battery Charging”.

  • Stop/Start OFF switch is pushed.

  • Stop/Start related system malfunction.

  • Steering wheel is turned beyond threshold.
