178 STARTING AND OPERATING
STOP/START SYSTEM — AUTOMATIC
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. Releasing the
brake pedal or pressing the accelerator pedal will
automatically restart the engine.
ESS vehicles have been upgraded with a
heavy-duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
NOTE:
It is recommended that the Stop/Start system 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.
