If No Steam Is Coming From Your

Engine

If you get an engine overheat warning but see or hear

no steam, the problem may not be too serious.

Sometimes the engine can get a little too hot when you:

• Climb a long hill on a hot day.

• Stop after high-speed driving.

• Idle for long periods in traffic.

• Tow a trailer.

If you get the overheat warning with no sign of steam,

try this for a minute or so:

1. If your air conditioner is on, turn it off.

2. Turn on your heater to full hot at the highest fan

speed and open the windows as necessary.

3. If you are in a traffic jam, shift to NEUTRAL (N);

otherwise, shift to the highest gear while

driving — DRIVE (D) or THIRD (3).

If you no longer have the overheat warning, you can

drive. Just to be safe, drive slower for about 10 minutes.

If the warning does not come back on, you can drive

normally.

If the warning continues, pull over, stop, and park your

vehicle right away.

If there is still no sign of steam, idle the engine for

three minutes while you are parked. If you still have the

warning, turn off the engine and get everyone out of

the vehicle until it cools down. Also, see “Overheated

Engine Protection Operating Mode” later in this section.

You may decide not to lift the hood but to get service

help right away.

Overheated Engine Protection

Operating Mode

This emergency operating mode lets your vehicle 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 a signiﬁcant loss in power and engine

performance. The temperature gage indicates an

overheat condition exists. 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 5-13.
