Panel" for further information.
If the "POWER STEERING HOT" message and an
icon are displayed on the instrument cluster
screen, it indicates that extreme steering
maneuvers may have occurred, which caused
an over temperature condition in the power
steering system. You will lose power steering
assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to "Instrument Cluster Display"
in "Getting To Know Your Instrument Panel" for
further information.
NOTE:
Even if power steering assistance is no longer

operational, 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 your 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. 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.
