Vehicle Care 9-23

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 the

instrument panel, to indicate the

vehicle has entered overheated

engine protection operating mode.

The temperature gauge also

indicates an overheat condition

exists. Driving extended km (miles)

and/or towing a trailer in the

overheat protection mode should

be avoided.

Power Steering Fluid

See Engine Compartment Overview

on page 9‑6

for information on the

location of the power steering fluid

reservoir.

When to Check Power Steering

Fluid

It is not necessary to regularly

check power steering fluid unless a

leak is 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

Check the level after the vehicle

has been driven for at least

twenty minutes so the fluid is warm.

To check the power steering fluid:

1. Turn the ignition to LOCK/OFF

and let the engine compartment

cool down.

2. Wipe the cap and the top of the

reservoir clean.

3. Unscrew the cap and pull it

straight up.

4. Wipe the dipstick with a

clean rag.

5. Replace the cap and completely

tighten it.

6. Remove the cap again and look

at the fluid level on the dipstick.
