SYSTEM MALFUNCTION
If there is a malfunction in the Stop/Start
system, the system will not shut down the
engine. A “SERVICE STOP/START SYSTEM”
message will appear in the instrument cluster
display Ú page 111.
If the “SERVICE STOP/START SYSTEM”
message appears in the instrument cluster
display, have the system checked by an
authorized dealer.
If a malfunction occurs during an autostop, the
vehicle may not auto start and will need a key
start.
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.

WARNING!
Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 Volt electrical system.
Serious injury or death could result if you do
not disconnect both batteries. To learn how
to properly disconnect, see an authorized
dealer.
