light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires except the
spare.
The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
Af ter the ignition switch is placed in the ON
position, this light illuminates for about 1
second and turns off.
Low tire pressure warning
If the vehicle is being driven with low tire
pressure, the warning light will illumi-
nate. A “Tire Pressure Low - Add Air”
warning also appears in the vehicle in-
formation display.
When the low tire pressure warning light
illuminates, you should stop and adjust
the tire pressure of all four tires to the
recommended COLD tire pressure shown
on the Tire and Loading Information la-
bel located in the driver's door opening.
The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. Af ter the tire is in-
flated to the recommended pressure,
Instruments and controls2-13

the vehicle must be driven at speeds
above 16 mph (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains
illuminated.
For additional information, see “Vehicle in-
formation display — 7 inch (18 cm) Type B”
(P. 2-34), and “Tire Pressure Monitoring Sys-
tem (TPMS)” (P. 5-5) and (P. 6-3).
TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The
light will remain on af ter 1 minute. Have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
The "Tire Pressure Low — Add Air" warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P. 5-5) and
(P. 6-3).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
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.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.

dealer for this service. When the ignition switch is placed in the ON
position, the power steering warning light
illuminates. Af ter starting the engine, the
power steering warning light turns off. This
indicates the power steering is operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering is not function-
ing properly and may need servicing. Have
the power steering checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
For additional information, see “Power
steering” (P. 5-172).

unavailable. For additional information, see
“Rear Automatic Braking (RAB)” (P. 5-127).
Slip indicator light
This indicator light will blink when the Ve-
hicle Dynamic Control (VDC) system is op-
erating, thus alerting the driver to the fact
that the road surface is slippery and the
