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 addi-
tional 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.
