GENERAL
1. CAUTIONS FOR DI ENGINE
This chapter describes the cautions for DI engine equipped vehicle. This includes the water
separation from engine, warning lights, symptoms when engine malfunctioning, causes and
actions.
1) DI Engine
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing
electrically, delivers high power and reduces less emission.
2) System Safety Mode
When a severe failure has been occurred in a vehicle, the system safety mode is activated to
protect the system. It reduces the driving force, restricts the engine speed (rpm) and stops
engine operation. Refer to "Diagnosis" section in this manual.
3) Water Separator Warning Light
When the water level inside water separator
in fuel filter exceeds a certain level (approx.
39 cc), this warning light comes on and
buzzer sounds.
Also, the driving force of the vehicle
decreases (torque reduction). If these
conditions occur, immediately drain the
water from fuel filter.
For the draining procedures, please refer to
"How to drain the water from fuel filter"
section.
4) Priming Pump
The priming pump installed in fuel pump is the device to fill the fuel into the fuel filter. When the
vehicle is under the conditions as below, press the priming pump until it becomes rigid before
starting the engine.
5) Conditions for Using Priming Pump
