the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the light does not illuminate with
the ignition switch placed in the ON
position, have the vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
• If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle
speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as
possible. Driving with under-inflated
tires may permanently damage the
tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter adjusting the tire
pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a spare
tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service.
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
2-14Instruments and controls

CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
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
gallons (11.4 liters) of fuel in the fuel tank.
Af ter a few driving trips, the
light
should turn off if no other potential emis-
sion control system malfunction exists. 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 system inspection/maintenance
test. For additional information, see “Readi-
ness for Inspection/Maintenance (I/M) test”
(P. 10-24).
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-
tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. 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 af ter a few driving
trips. If thelight does not turn off
af ter 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 emis-
sion 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 rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
