Overheated Engine Protection Operating Mode; Power Steering Fluid - Chevrolet 2010 Impala Owner's Manual

Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle
to be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates firing groups of
cylinders helps prevent engine damage. In this mode,
you will notice a significant loss in power and engine
performance. The coolant temperature gage will indicate
an overheat condition exists. 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, change the oil
and reset the oil life system. See Engine Oil
on page 6-15.

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.
The power steering fluid
reservoir is located toward
the rear of the engine
compartment on the
passenger's side of the
vehicle. See Engine
Compartment Overview on
page 6-14 for reservoir
location.
