Jeep Wrangler: Red Warning Lights / Engine Coolant Temperature Warning Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too
high, this indicator will illuminate and
a single chime will sound. If the temperature
reaches the upper limit, a continuous chime will
sound for four minutes or until the engine is
able to cool, whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/
C) system is on, turn it off. Also, shift the
transmission into NEUTRAL (N) and idle the vehicle. If the temperature reading
does not
return to normal, turn the engine off
immediately and call for service.
This warning light will
illuminate to
indicate a problem with the ETC
system. If a problem is detected while
the vehicle is running, the light will
either stay on or flash depending on the nature
of the problem...
This indicator will illuminate
when the
hood is ajar/open and not fully
closed.
NOTE:
If the vehicle is moving, there will also be a
single chime...
Other information:
Diesel Exhaust Fluid (DEF) is considered a very
stable product with a long shelf life. If DEF is kept
in temperatures between 10° and 90°F (-12°
and 32°C), it will last a minimum of one year.
DEF is subject to freezing at the lowest
temperatures...
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than
15 seconds...
