138 STARTING AND OPERATING
FUEL SAVER TECHNOLOGY 5.7L ONLY —
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system provides
enhanced vehicle response and increased ease of
maneuverability in tight spaces. The system
adapts to different driving conditions. If the electric
power steering system experiences a fault that
prevents it from providing assistance, you will still
have the ability to steer the vehicle manually.
NOTE:
Alternate electric power steering efforts (Normal,
Comfort and Sport) can be selected through the
Uconnect System Ú page 200. If SPORT mode is
selected, steering efforts are optimized for sporty
driving.
If the Electric Power Steering warning
icon is displayed and the “SERVICE
POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE
SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for service
Ú page 106.
NOTE:
Even if the 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, espe-
cially at low speeds and during parking maneu-
vers.
If the condition persists, see an authorized
dealer for service.
If the Steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, they
indicate that extreme steering maneuvers may
have occurred which caused an over temperature
condition in the electric power steering system.
Once driving conditions are safe, pull over and let
the vehicle idle for a few moments until the icon
and message turn off.
STOP/START SYSTEM — IF EQUIPPED
The 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. Releasing the brake pedal or
pressing the accelerator pedal will automatically
re-start the engine.
This vehicle has been upgraded with a heavy-duty
starter, enhanced battery, and other upgraded
engine parts, to handle the additional engine starts.
AUTOSTOP 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 Ú page 95.
The vehicle must be completely stopped.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
