Vehicle equipment
Please note that this manual contains all
the standard equipment, country-specific
equipment and special equipment for this
model series. Thus, some equipment or
features described in this manual may not
be installed onto your vehicle or are only
available in some markets. For the further
configuration information, please refer to
relevant sales information or consult with
your distributor selling the vehicle to you.
Tips for safety
The emission control system may vary
with different engine models. For the par-
ticular equipment, please refer to the ac-
tual vehicle.
Do not modify any part of the engine or
emission control system.
Oxygen sensor
The oxygen sensor measures the concen-
tration of oxygen in the exhaust gases and
reports that information to the ECU in or-
der to regulate the engine's fuel-air ratio
for optimum combustion efficiency and to
reduce the amount of carbon monoxide,
hydrocarbons, and nitrogen oxides con-
tained in the exhaust.
Catalytic converter
Catalytic converter is the most important
external purifier installed in vehicle's ex-
haust system. The catalytic converter con-
tains metallic catalysts that convert harm-
ful gases such as carbon monoxide,
hydrocarbons, and nitrogen oxides into
harmless carbon dioxide, water, and nitro-
gen gas through oxidation and reduction
reactions.
The catalytic converter only needs to be
used correctly and generally does not re-
quire maintenance. Thus, it should not be
disassembled without cause. If it needs to
be replaced, it must match the engine.
Caution
To avoid damaging the catalytic converter,
please pay attention to the following items:
〉
Do not use leaded gasoline or gasoline
with more than the standard amount of
manganese or sulfur.
〉
Do not drive the vehicle when the fuel
level is extremely low. If the fuel is ex-
hausted, it will cause the engine to mis-
fire (this may be confirmed by unstable
engine operation or a loss of power),
damaging the catalytic converter.
〉
Do not idle the engine at high speed for
an extended time (5 minutes or longer).
〉
When a problem with the engine is indi-
cated (such as shutdown or perform-
ance degradation), please do not contin-
ue driving the vehicle.
〉
Do not operate the engine with the spark
plugs removed.
〉
Do not start the vehicle by pushing or
pulling it.
〉
Do not add too much engine oil.
