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, you will notice a loss in power and engine performance. This operating mode allows the vehicle to be driven to a safe place in an emergency. 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 6‑17. Engine Fan Noise If the vehicle has a clutched engine cooling fan, when the clutch is engaged, the fan spins faster to provide more air to cool the engine. In most everyday driving conditions, the fan is spinning slower and the clutch is not fully engaged. This improves fuel economy and reduces fan noise. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, the fan speed increases as the clutch more fully engages, so you may hear an increase in fan noise. This is normal and should not be mistaken as the transmission slipping or making extra shifts. It is merely the cooling system functioning properly. The fan will slow down when additional cooling is not required and the clutch disengages. You may also hear this fan noise when you start the engine. It will go away as the fan clutch partially disengages. If the vehicle has electric cooling fans, you may hear the fans spinning at low speed during most everyday driving. The fans may turn off if no cooling is required. Under heavy vehicle loading, trailer towing, and/or high outside temperatures, or if you are operating the air conditioning system, the fans may change to high speed and you may hear an increase in fan noise. This is normal and indicates that the cooling system is functioning properly. The fans will change to low speed when additional cooling is no longer required. 6-39

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, you will notice a loss in power and engine

performance. This operating mode allows the vehicle to

be driven to a safe place in an emergency. 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

Engine Fan Noise

If the vehicle has a clutched engine cooling fan, when

the clutch is engaged, the fan spins faster to provide

more air to cool the engine. In most everyday driving

conditions, the fan is spinning slower and the clutch is

not fully engaged. This improves fuel economy and

reduces fan noise. Under heavy vehicle loading, trailer

towing, and/or high outside temperatures, the fan speed

increases as the clutch more fully engages, so you may

hear an increase in fan noise. This is normal and should

not be mistaken as the transmission slipping or making

extra shifts. It is merely the cooling system functioning

properly. The fan will slow down when additional cooling

is not required and the clutch disengages.

You may also hear this fan noise when you start the

engine. It will go away as the fan clutch partially

disengages.

If the vehicle has electric cooling fans, you may hear

the fans spinning at low speed during most everyday

driving. The fans may turn off if no cooling is required.

Under heavy vehicle loading, trailer towing, and/or high

outside temperatures, or if you are operating the air

conditioning system, the fans may change to high

speed and you may hear an increase in fan noise. This

is normal and indicates that the cooling system is

functioning properly. The fans will change to low speed

when additional cooling is no longer required.
