Jeep Wrangler: STARTING AND OPERATING / NORMAL OPERATION — DIESEL ENGINE
Observe the following when the diesel engine is
operating:
- All message center lights are off.
- Malfunction Indicator Light (MIL) is off.
- Engine Oil Pressure telltale is not illuminated.

complete, the voltmeter needle will stabilize.
The engine is equipped with a glow plug
preheating system. If the instructions in this
manual are followed, the engine should start in
all conditions and no type of starting fluid
should be used...
