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 sys-

tem 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 re-

duce the three-way catalyst’s ability to

help reduce exhaust pollutants.

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 driv-

ing if the engine misfires, or if notice-

able loss of performance or other un-

usual

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.

TIRE PRESSURE MONITORING

SYSTEM (TPMS)

Each tire, including the spare (if provided),

should be checked monthly when cold and in-

flated to the inflation pressure recommended by

the vehicle manufacturer on the vehicle placard

or tire inflation pressure label. (If your vehicle has

tires of a different size than the size indicated on

the vehicle placard or tire inflation 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 illuminates 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 signifi-

cantly 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 substitute for

proper tire maintenance, and it is the driver’s

responsibility to maintain correct tire pressure,

even if under-inflation has not reached the level to

trigger illumination of the TPMS low tire pressure

telltale.
Your vehicle has also been equipped with a

TPMS malfunction indicator to indicate when the

system is not operating properly. The TPMS mal-

function indicator is combined with the low tire

pressure telltale. When the system detects a

malfunction, the telltale will flash for approxi-

mately one minute and then remain continuously

illuminated. This sequence will continue upon

Starting and driving
