Overheated Engine Protection Operating Mode; Power Steering Fluid - Cadillac 2009 CTS Owner's Manual

Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven
to a safe place in an emergency. Should a hot engine
condition exist, an overheat protection mode which
alternates firing groups of cylinders helps prevent engine
damage. In this mode, there is a loss in power and engine
performance. Driving extended miles (km) and/or towing
a trailer in the overheat protection mode should be
avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss and change the oil. See Engine
Oil on page 5-18.

Power Steering Fluid

When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or you
hear an unusual noise. A fluid loss in this system could
indicate a problem. Have the system inspected and
repaired.
See Engine Compartment
Overview on page 5-14 for
the location of the power
steering fluid reservoir.
