CONNECTOR SYMBOLS=NJGI0003S0201Most of connector symbols in wiring diagrams are shown from the
terminal side.
Connector symbols shown from the terminal side are enclosed
by a single line and followed by the direction mark.
Connector symbols shown from the harness side are enclosed
by a double line and followed by the direction mark.
Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connec-
tor. For description and how to disconnect, refer to EL-7, “HAR-
NESS CONNECTOR”.

Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.

ing the mixture ratio and correcting the mixture ratio if necessary) at themiddle of replacement interval.
(2) Periodic maintenance is not required. However, if valve noise increases, check valve clearance.
(3) Fuel filter is maintenance-free. For service procedures, refer to FE section.
(4) Perform only according to “Maintenance Under Severe Driving Conditions” for models without Euro-OBD system. For
models with Euro-OBD system, periodic maintenance is not required.

Maintenance Under Severe Driving Conditions
(Annual Driving Distance < 30,000 km/year)
=NJMA0043S03The maintenance intervals shown on the preceding pages are for normal operating conditions. If the vehicle
is mainly operated under severe driving conditions as shown below, more frequent maintenance must be per-
formed on the following items as shown in the table.
A — Driving under dusty conditions
B — Driving repeatedly short distances
C — Towing a trailer or caravan
D — Extensive idling
E — Driving in extremely adverse weather conditions or in areas where ambient temperatures are either
extremely low or extremely high
F — Driving in high humidity areas or in mountainous areas
G — Driving in areas using salt or other corrosive materials
H — Driving on rough and/or muddy roads or in the desert
I — Driving with frequent use of braking or in mountainous areas
J — Frequent off road use or driving in water
K — Sustained high speed driving
