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"
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, a significant loss in power
and engine performance will be
noticed. The coolant temperature
gauge will indicate an overheat
condition exists. Driving
extended km (mi) 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 10‑8.
Power Steering Fluid
The power steering fluid reservoir
is located toward the rear of the
engine compartment on the
passenger side of the vehicle.
See Engine Compartment Overview
on page 10‑6 for reservoir location.
When to Check Power
Steering Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected 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
To check the power steering fluid,
do the following:
1. Turn the key off and let the
engine compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the
dipstick with a clean rag.
4. Replace the cap and completely
tighten it.
5. Remove the cap again and look
at the fluid level on the dipstick.
