THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol 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 compo-
nents.
. 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. 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
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
you visit an INFINITI retailer for this
service.
. 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
inflated to the inflation pressure recom-
mended 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 Mon-
itoring 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 significantly under-inflated tire causes
the tire to overheat 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 sub-
stitute 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 malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions in-
terfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.)
4. Push the ignition switch while depressing the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears on the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Intelligent Key
battery replacement” (P.8-25).)
. Make sure the area around the vehicle is
clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window washer
fluid as frequently as possible, or at least
whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat and adjust head restraints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passengers
to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to the
ON position. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-10).)

PRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The SET
indicator on the vehicle information dis-
play will then blink to warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the SET indicator blinks, turn the cruise
control main switch off and have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
. The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the COAST/
SET, ACCELERATE/RESUME or CAN-
CEL switch. To properly set the cruise
control system, perform the steps below
in the order indicated.
WARNING
Do not use the cruise control when
driving under the following conditions:
. when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of vehicle
control and result in an accident.
