that the automatic transmission P
(Park) position will not function and
could result in the vehicle moving un-
expectedly, causing serious personal
injury or property damage. Always
set the parking brake. For additional
information, refer to “Using 4–wheel
drive (4WD)” in the “Starting and driv-
ing” section of this manual.

that the automatic transmission P
(Park) position will not function and
the transfer case is in neutral.
• When parking, always make sure that
the 4WD shif t indicator light illumi-
nates and the parking brake is set.
Failure to engage the transfer posi-
tion in 2WD, 4H or 4LO could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage. •
Shif t the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the
ATP warning light when the shif t le-
ver is in the P position and the ATP
warning light is on. (Before shif ting

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.
Instruments and controls2-15

•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 replacing 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.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.

WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, refer to “Changing wheels and tires” in the “Do-it-yourself ” section of this manual. Many factors including tire inflation,
alignment, driving habits and road conditions affect tire wear and when tires should be replaced. Setting the tire replacement
indicator for a certain driving distance does not mean your tires will last that long. Use the tire replacement indicator as a guide
only and always perform regular tire checks. Failure to perform regular tire checks, including tire pressure checks could result in
tire failure. Serious vehicle damage could occur and may lead to a collision, which could result in serious personal injury or death.
