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 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 an INFINITI retailer.
► 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.
