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:

  • City Driving — When stopped, shift the transmission into NEUTRAL (N) and increase engine idle speed.
  • Highway Driving — Reduce your speed.
  • Up Steep Hills — Select a lower transmission gear.
  • Air Conditioning — Turn it off temporarily.

NOTE:

If the coolant temperature is too high, the A/C will automatically turn off.

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...
