Engine Overheating
There is an engine coolant
temperature warning light on your
vehicle’s instrument panel. See
Engine Coolant Temperature Gage
on page 4-17.
If Steam Is Coming From Your
Engine
{ CAUTION
Steam from an overheated
engine can burn you badly,
even if you just open the hood.
Stay away from the engine if
you see or hear steam coming
from it. Just turn it off and get
everyone away from the vehicle
until it cools down. Wait until
there is no sign of steam or
coolant before you open
the hood.

CAUTION (Continued)
If you keep driving when your
engine is overheated, the
liquids in it can catch fire. You
or others could be badly
burned. Stop your engine if it
overheats, and get out of the
vehicle until the engine is cool.
Notice: If the engine catches fire
because of being driven with
no coolant, your vehicle can be
badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
If No Steam Is Coming From
Your Engine
An engine coolant temperature
warning can indicate a serious
problem. See Engine Coolant
Temperature Gage on page 4-17.
If you get an engine coolant
temperature 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.
If you get the engine coolant
temperature warning with no sign of
steam, try this for a minute or so:
1. If your air conditioner is on, turn
it off.
2. In heavy traffic, let the engine idle
in N (Neutral) while stopped. If it
is safe to do so, pull off the road,
shift to P (Park) or N (Neutral) and
let the engine idle.
3. Turn on your heater to full hot at
the highest fan speed and open
the windows as necessary.
