3. CAUTIONS FOR DI ENGINE
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.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission..
System Safety Mode 2.
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.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the
<008c0095008e00900095008c02c5009a004700970096009e008c009900470096009c009b0097009c009b00470094008800a00047008b008c008a0099008c0088009a008c0047009600990047009b008f008c0047008c0095008e00900095008c0047009400

Water Separator Warning Lamp 4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 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.

(2) Di engine and its expected problems and remedies can be caused by
water in fuel
System supplement against paraffin separation ▶
In case of Diesel fuel, paraffin, one of the elements, can be separated from fuel during winter and then
can stick on the fuel filter blocking fuel flow and causing difficult starting finally. Oil companies supply
summer fuel and winter fuel by differentiating mixing ratio of kerosene and other elements by region and
season. However, above phenomenon can be happened if stations have poor facilities or sell improper
fuel for the season. In case of DI engine, purity of fuel is very important factor to keep internal
preciseness of HP pump and injector.
Accordingly, more dense mesh than conventional fuel filter is used. To prevent fuel filter internal clogging
due to paraffin separation, SYMC is using fuel line that high pressure and temperature fuel injected by
injector returns through fuel filter to have an effect of built-in heater (see fuel system).
System supplement and remedy against water in fuel ▶
As mentioned above, some gas stations supply fuel with excessive than specified water. In the
conventional IDI engine, excessive water in the fuel only causes dropping engine power or engine
hunting. However, fuel system in the DI engine consists of precise components so water in the fuel can
cause malfunctions of HP pump due to poor lubrication of pump caused by poor coating film during high
speed pumping and bacterization (under long period parking). To prevent problems can be caused by
excessive water in fuel, water separator is installed inside of fuel filter. When fuel is passing filter, water
that has relatively bigger specific gravity is accumulated on the bottom of the filter.
Water drain from water separator ▶
If water in the separator on the fuel filter exceeds a certain level, it will be supplied to HP pump with fuel,
so the engine ECU turns on warning lamp on the meter cluster and buzzer if water level is higher than a
certain level.
Due to engine layout, a customer cannot easily drain water from fuel filter directly, so if a customer
checks in to change engine oil, be sure to perform water drain from fuel filter.
Water
separator
To separate the water from the fuel filter,
remove the fuel filter assembly first.

ABS Warning Light
This warning light comes on
when the ignition switch is turned
to "ON" position and should go
out if the system is normal.
The vehicle with ABS performs
self-diagnosis. During this
diagnosis, brake pedal vibration
and noise may be apparent
when the driving motors
discharges the hydraulic
pressure from the internal
hydraulic device.4WD IndicatorLow Fuel Level
Warnig Light
This warning light
comes on when the
fuel will soon be
exhausted. The time
it takes turn on,
however, varies
according to the
gradient of the
vehicle.
4WD HIGH Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD LOW Indicator
The lamp blinks momentarily during
the change of driving mode.
4WD CHECK Warning Light
This indicates that there is something
wrong in the transfer case system.

Auto Cruise Control
Indicator
Operating the cruise
control switch turns on
the indicator lamp to
indicate the cruise
control system is
activated.
Water Separator Warning Light
This lamp comes on to warn the driver of
water in the fuel tank which causes the loss
of engine power. When a certain amount of
water is accumulated, the lamp comes on
and a chime sounds.
Engine CHECK Warning Light
This warning light comes on when the
ignition switch is turned to "ON"
position and should go out if the
system related to engine control is
normal.
This comes on when different sensors
and devices related to engine control
are defective.
Winter Mode
Indicator
Pressing the "W" side of the
automatic transmission mode
selector switch switches the driving
mode to winter mode and turns on
the indicator lamp.
Use this mode to drive off smoothly
on icy and slippery roads.
Charge Warning Light
This warning light comes on when the
ignition switch is turned on and go off when
the engine is started.
If this light doesn't go off after engine starting,
it means there is a malfunction in the system.
Engine Hood Open Warning Light
When the engine hood is open, this light
comes on to inform the driver.
Hazard Indicator
This indicator blinks when the
hazard warning flashers are
switched on.
