If the "SERVICE POWER STEERING" or "POWER
STEERING ASSIST OFF - SERVICE SYSTEM"
message and a steering wheel icon are
displayed on the instrument cluster screen, it
indicates that the vehicle needs to be taken to an
authorized dealer for service. It is likely the vehicle has lost
power steering assistance
page 68.
Ú
NOTE:
 Even if the power steering assistance is no longer oper-
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 The power steering system is fully electric; it requires
no power steering fluid.
 If the condition persists, see an authorized dealer for
service.
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, pressing
the accelerator pedal or shifting out of DRIVE (D) 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.
