STARTING AND OPERATING 169
NOTE:
Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
If the condition persists, see an authorized dealer for
service.
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 re-start 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.

AUTOMATIC MODE
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY and if
all other conditions are met, can go into a
STOP/START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must Occur:
The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start
section. Refer to “Instrument Cluster” in “Getting To
Know Your Instrument Panel” for further information.
The vehicle must be completely stopped.
The gear selector must be in a forward gear and the
brake pedal depressed.
The engine will shut down, the tachometer will move to the
zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine running condition.

WARNING!
Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple-
mental 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.
