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.
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...
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...
Other information:
To raise the head restraint, pull upward on the
head restraint. To lower the head restraint,
push the adjustment button located on the
base of the head restraint, and push downward on the head restraint. The release
button does
not need to be pushed to adjust the head
restraint...
Head restraints are designed to reduce the risk
of injury by restricting head movement in the
event of a rear impact. Head restraints should
be adjusted so that the top of the head restraint
is located above the top of your ear.
WARNING!
All occupants, including the driver, should
not operate a vehicle or sit in a vehicle’s
seat until the head restraints are placed in
their proper positions in order to minimize
the risk of neck injury in the event of a
crash...
