Start/Stop System - Operation

STOP/START

The START/STOP feature operation works in part like a non-STOP/START system.

To Start The Engine While In The STOP/START AUTO STOP ACTIVE Mode -

When the shift lever is in NEUTRAL, the engine will start when the accelerator pedal is pressed. The vehicle will go into STOP/START SYSTEM NOT READY mode until the vehicle speed is greater than 3 mph (5 km/h).

Conditions that force a manual key cycle start while in STOP/START AUTO STOP ACTIVE mode:

The engine will not start automatically if:

- The driver's seatbelt was unbuckled.

- The engine hood has been opened.

- A STOP/START system error occurs.

The engine may then only be restarted with an ignition key cycle. The STOP/START KEY START REQUIRED message will appear in the Electronic Vehicle Information Center (EVIC) under these conditions.

To Manually Turn Off The Start Stop System:

- Press the STOP/START Off switch (located on the Integrated Center Stack Switch Bank otherwise known as the ICS)

- The STOP/START OFF message will appear in the EVIC.

- At the next vehicle stop (after turning off the STOP/START system) the engine will not be stopped.

- If the STOP/START system is manually turned off, the engine can only be started and stopped by cycling the ignition switch.

- The STOP/START system will reset itself back to an ON condition every time the ignition is turned off and back on.

To manually turn on the STOP/START system:

1. Press the STOP/START off switch (located on the ICS.

2. The light on the switch will turn off.
