The fuel-saving Engine Stop/Start system automatically turns off the engine, referred to as an Auto Stop, when the brake pedal is pressed and the vehicle is at a complete stop, if certain operating conditions are met. In Auto Stop mode, the tachometer will read AUTO STOP. When the brake pedal is released or the accelerator pedal is pressed, the engine will restart. After parking the vehicle and turning off the engine, the tachometer will read OFF.
The engine may remain running or restart when the vehicle is stopped if:
• A minimum vehicle speed was not reached prior to stopping.
• The engine or transmission is not at the required operating temperature.
• The outside temperature is not in the required operating range.
• The shift lever is in any gear other than Drive (D).
• The battery charge is low.
• The climate control system requires the engine to run based on the current settings.
• The Auto Stop has reached the maximum allowed time.
AUTO ENGINE STOP/START DISABLE
Press the $ button on the left side of the instrument panel to turn off the system. The button indicator turns off when the system is disabled.
