Instruments and controls2-21

Malfunction Indicator Light(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the fuel-filler
cap is loose or missing, or if the vehicle runs out
of fuel. Check to make sure the fuel-filler cap is
installed and closed tightly, and that the vehicle
has at least 3 gal (11.4 L) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 sec-
onds and then blinks for 10 seconds when the
engine is not running, it indicates that the vehicle
is not ready for an emission control system
inspection/maintenance test. For additional infor-
mation, refer to “Readiness for
inspection/maintenance (I/M) test” in the “Tech-
nical and consumer information” section of this
manual.
Operation
The MIL will come on in one of two ways: ●
MIL on steady — An emission control system
malfunction has been detected. Check the
fuel-filler cap if the LOOSE FUEL CAP
warning appears in the trip computer. 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 the
light does not
turn off after a few driving trips, have the
vehicle inspected. It is recommended that
you visit a NISSAN dealer for this service.
You do not need to have your vehicle towed
to the dealer.
● MIL blinking — An engine misfire has been
detected which may damage the emission
control system. To reduce or avoid emission
control system damage:
– 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 MIL may stop blinking and come on steady.
Have the vehicle inspected. It is recommended
that you visit a NISSAN dealer for this service.
You do not need to have your vehicle towed to the
dealer.
CAUTION

FUEL-FILLER CAP
WARNING
●Gasoline 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. ●
Do 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.
● Use 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
(MIL) to come on.
● Never pour fuel into the throttle body to
attempt to start your vehicle.
● Do 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
●The LOOSE FUEL CAP warning mes-
sage will be displayed if the fuel-filler
cap is not properly tightened. It may
take a few driving trips for the message
to be displayed. Failure to tighten the
fuel-filler cap properly after the LOOSE
FUEL CAP warning message is dis-
played may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate.
● Failure to tighten the fuel-filler cap
properly may cause the
Malfunc-
tion Indicator Light (MIL) to illuminate.
If the
light illuminates because
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 the
light does not turn off after a
few driving trips, have the vehicle in-
spected. It is recommended that you
visit a NISSAN dealer for this service.

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. It is recommended that you
visit a NISSAN dealer 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 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 1 minute and then remain continuously
illuminated. This sequence will continue upon
Starting and driving5-3

●To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so equipped)
and evenly distribute the load. Secure
heavy loads in the cargo area as far
forward and as low as possible. Do not
equip the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to roll over.
● Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
● Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
● Always drive with the floor mats in place
as the floor may become hot.
● Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more affected
by strong side winds. Slower speeds
ensure better vehicle control.
● Do not drive beyond the performance
capability of the tires, even with 4WD
engaged (if so equipped) . ●
For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
● Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control. ●
If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same speeds
as passenger cars. Failure to operate
this vehicle correctly could result in loss
of control and/or a rollover accident.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
● Be sure to check the brakes immedi-
ately after driving in mud or water. For
additional information, refer to “Wet
brakes” in this section.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
