If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual.
Operation
The malfunction indicator light will come on in
one of two ways:
cMalfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap. If
the fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive the
vehicle. The
light should turn off after
a few driving trips. If thelight does not
turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.
cMalfunction indicator light blinking — An en-
gine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:– do not drive at speeds above 45 MPH
(72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator light may stop blinking
and come on steady. Have the vehicle inspected
by a NISSAN dealer. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Overdrive off indicator light
(automatic transmission
models only)
This light comes on when the overdrive function
is OFF.
The automatic transmission overdrive function is
controlled by the overdrive switch.See “Driving the vehicle” in the “Starting and
driving” section of this manual.

FUEL-FILLER CAP
The fuel-filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten, turn
the cap clockwise until ratcheting clicks are
heard.
Put the fuel-filler cap on the cap holder
s1while
refueling.
WARNING
cGasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
cFuel may be under pressure. Turn the
cap a third of a turn, and wait for any
“hissing” sound to stop to prevent fuel
from spraying out and possibly causing
personal injury. Then remove the cap.
cDo not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
cUse only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
cNever pour fuel into the throttle body to
attempt to start your vehicle.cDo not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices when
filling.
– Keep the pump nozzle in contact
with the container while you are fill-
ing it.
– Use only approved portable fuel con-
tainers for flammable liquid.

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep 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.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo 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
underinflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and check
your tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly un-
derinflated tire causes the tire to overheat and can
lead to tire failure. Underinflation 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 underinflation 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
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:
cThis system does not monitor the tire pres-
sure of the spare tire.
cThe low tire pressure warning system will
activate only when the vehicle is driven at
speeds above 16 MPH (26 km/h) . Also, this
system may not detect a sudden drop in tire
pressure (for example a flat tire while driving) .
