Equipped
If the “POWER STEERING SYSTEM OVER
TEMP” message and a icon are displayed on

ing maneuvers may have occurred, which
caused an over temperature condition in the power

longer exists. Once driving conditions are safe, then pull
over and let vehicle idle. After five minutes, the system
will cool and return to normal operation. Refer to “Power

mation.

•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 your authorized dealer for
service.
