Jeep Wrangler: STARTING AND OPERATING / STOP/START SYSTEM — MANUAL TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is developed to reduce fuel consumption. The system will stop the engine automatically during a vehicle stop if the required conditions are met. Pressing the clutch pedal will automatically restart the vehicle.
ESS vehicles have been upgraded with a heavy duty starter, enhanced battery, and other upgraded engine parts, to handle the additional engine starts. Vehicles equipped with eTorque contain a heavy duty motor generator and an additional hybrid electric battery to store energy from vehicle deceleration for use on engine startup after a stop as well as providing launch torque assist.
NOTE:
It is recommended that Stop/Start be disabled during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary battery used to power the Stop/Start system and the 12 Volt vehicle electrical system. The secondary battery is located behind the wheel well for the front passenger wheel.
