10-16 Vehicle Care
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the 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, there is significant loss in
power and engine performance. The engine coolant temperature
warning light comes on in the
instrument cluster, to indicate the
vehicle has entered overheated
engine protection operating mode.
The temperature gauge also
indicates an overheat condition
exists. Driving extended distances
and/or towing a trailer in the
overheat protection mode should be
avoided.
Power Steering Fluid
The power steering fluid reservoir is
located under the engine cover on
the passenger side toward the rear
of the engine compartment. See
Engine Compartment Overview on
page 10‑5.
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 an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
Check the level after the vehicle has
been driven for at least 20 minutes
so the fluid is warm.
To check the power steering fluid:
1. Set the ignition to OFF and let
the engine compartment
cool down.
2. Remove the engine cover. Refer toEngine Cover on page 10‑6.
3. Wipe the cap and the top of the reservoir clean.
4. Turn the cap counterclockwise and pull it straight up.
