Jeep Wrangler: NORMAL OPERATION — DIESEL ENGINE / Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission overheating in high ambient temperature conditions, take the following actions:

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
