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. Refer to "Instrument Cluster Display" in
"Getting to Know Your Instrument Panel" for
further information.
If the "SERVICE STOP/START SYSTEM"
message appears in the instrument cluster
display, have the system checked by an
authorized dealer.
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.
