Three-way catalyst
The three-way catalyst is an emission control device installed in the exhaust system. Exhaust gases in the three-way catalyst are burned at high temperatures to help reduce pollutants.
WARNING
● The exhaust gas and the exhaust system are very hot. Keep people, animals or flammable materials away from the exhaust system components.
● Do not stop or park the vehicle over flammable materials such as dry grass, waste paper or rags. They may ignite and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously reduce
the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driving
if the engine misfires, or if noticeable
loss of performance or other unusual
operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
