If Steam Is Coming From The
Engine Compartment
{
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. 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.
If you keep driving when the
vehicles engine is overheated, the
liquids in it can catch fire. You or
others could be badly burned.
Stop the engine if it overheats,
and get out of the vehicle until the
engine is cool.
See Overheated Engine
Protection Operating Mode on
page 5-24 for information on
driving to a safe place in an
emergency.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the
engine can get a little too hot when
the vehicle:
•
Climbs a long hill on a hot day.
•
Stops after high-speed driving.
•
Idles for long periods in traffic.
•
Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to
N (Neutral), otherwise, shift
to the highest gear while
driving — D (Drive) or L (Low).
Service and Appearance Care
If the temperature overheat gage is
no longer in the overheat zone
or an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle
slow for about 10 minutes. Keep a
safe vehicle distance from the car in
front of you. If the warning does
not come back on, continue to drive
normally.
If the warning continues, pull
over, stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see "Overheated
Engine Protection Operating
Mode" next in this section.
