10-22 Vehicle Care

Overheated Engine

Protection

Operating Mode

If an overheated engine condition

exists and the ENGINE POWER IS

REDUCED message is displayed,

an overheat protection mode which

alternates firing groups of cylinders

helps prevent engine damage. In

this mode, a loss in power and

engine performance will be noticed.

This operating mode allows the

vehicle to be driven to a safe place

in an emergency. Driving extended

distances 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 10‑7.

Engine Fan

The vehicle has electric cooling

fans. The fans spinning at low

speed during most everyday driving

might be heard. The fans can turn

off if no cooling is required. Under

heavy vehicle loading, trailer towing,

and/or high outside temperatures,

or if operating the air conditioning

system, the fans can change to high

speed and an increase in fan noise

might be heard. This is normal and

indicates that the cooling system is

functioning properly. The fans

change to low speed when

additional cooling is no longer

required.

Power Steering Fluid

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.
