Jeep Wrangler: NORMAL OPERATION — DIESEL ENGINE / Engine Idling
Avoid prolonged idling, long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel may not burn completely. Incomplete combustion allows carbon and varnish to form on piston rings, cylinder head valves, and injector nozzles. Also, the unburned fuel can enter the crankcase, diluting the oil and causing rapid wear to the engine.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may require special
considerations. The following charts suggest these options:
Fuel Operating Range
NOTE:
Use “Ultra Low Sulfur Diesel Fuels (ULSD)” ONLY...
Stopping The Engine
After full load operation, idle the engine for a
few minutes before shutting it down. This idle
period will allow the lubricating oil and coolant
to carry excess heat away from the
turbocharger...

Manual Front Seat Forward/Rearward Adjustment
The seat can be adjusted forward or rearward by using a bar located by the front of the seat cushion, near the floor. While sitting in the seat, lift up on the bar located under the seat cushion and move the seat forward or rearward. Release the bar once you have reached the desired position. Then, using body pressure, move forward and rearward on the seat to be sure that the seat adjusters have latched.
