STOP/START SYSTEM — MANUAL
TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start 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.
