If No Steam
l i s Csrning 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.
2.
In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn't come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over,
stop,
and park your vehicle right away.
If there's still no sign of steam, you can idle the engine
for three minutes while you're parked. If you still
have the warning, turn off the engine and get everyone
out of the vehicle until it cools down.
