Jeep Wrangler: Cooling System Tips — Automatic Transmission / Do Not Operate The Engine With Low Oil Pressure
If the low oil pressure warning light turns on
while driving, stop the vehicle and shut down
the engine as soon as possible. A chime will
sound when the light turns on.
NOTE:
Do not operate the vehicle until the cause is
corrected. This light does not show how much
oil is in the engine. The engine oil level must be
checked under the hood.
CAUTION!
If oil pressure falls to less than normal
readings, shut the engine off immediately.
Failure to do so could result in immediate and
severe engine damage.
To reduce the potential for engine and
transmission overheating in high ambient
temperature conditions, take the following
actions:
City Driving — When stopped, shift the transmission
into NEUTRAL (N) and increase
engine idle speed...
All engine failures give some warning before the
parts fail. Be on the alert for changes in
performance, sounds, and visual evidence that
the engine requires service...
Other information:
Prior to engine shut down, the system will check
many safety and comfort conditions to see if
they are fulfilled. Situations when the engine
will not stop include (but not limited to):
Driver’s seat belt is not buckled.
Outside temperature is less than 10°F
(–12°C) or greater than 109°F (43°C)...
This indicator light will
illuminate for
approximately two seconds when the
ignition is turned to the ON/RUN
position. Its duration may be longer
based on colder operating conditions. Vehicle
will not initiate start until telltale is no longer
displayed...
