Problems on the Road
. . . 370
If you get the overheat warning
with no sign of steam:
1. Turn off your air conditioner
and turn the heater on to
maximum heat and maximum
fan speed.
Open the windows, if neces-
sary.
2. If you're in a traffic jam, shift
to
N
(Neutral).
3. Pull over and stop the vehicle
as soon as it is safe to do so.
Allow the engine to idle for a
few minutes.
If the coolant temperature
gage still shows an overheated
condition, pull over, stop and park
your vehicle right away.
If there is still no sign of steam, run
the engine at idle speed for about
five minutes while you are parked.
If the overheat warning continues,
turn off the engine and get every-
one out of the vehicle right away.
See "Overheat Protection
Mode" later in this section for
information.
CAUTION
An electric cooling fan can start
even if the engine is not
running. Be careful around any
underhood electric fan.
If the coolant in the surge tank has
been boiling, do not touch it until
it has cooled down.
The vehicle should be parked on a
level surface.
The coolant level can be checked
by looking at the see-through
surge tank without having to
remove the cap.
