140 STARTING AND OPERATING
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 designed 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.
A M
UTOSTOP ODE
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.
