c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
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
O
The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
O
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
O
Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
O
Keep your engine tuned up. Malfunc-
tions 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 no-
ticeable loss of performance or other un-
usual operating conditions are detected.
Have the vehicle inspected promptly by
an INFINITI dealer.
O
Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
O
Do not race the engine while warming it
up.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has
tires of a different size than the size indi-
cated on the vehicle placard or tire infla-
tion pressure label, you should determine
the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when
one or more of your tires is significantly
under-inflated. Accordingly, when the low
tire pressure telltale illuminates, you
should stop and check your tires as soon
as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substi-
