WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, see “Changing wheels and tires” (P. 8-39). 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.

•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
reduce the three-way catalyst's abil-
ity 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
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. 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, damag-
ing the three-way catalyst.
• Do not race the engine while warm-
ing 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
inflated to the inflation pressure recom-
mended 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 pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly under-
inflated tire causes the tire to overheat 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 substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation 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 malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion 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, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing 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.
Starting and driving5-5

Additional information:
• When using a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af ter
all four tires are inflated to the recom-
mended pressure, 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 in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure is
detected. The “Tire Pressure Low - Add
Air” warning turns off when the low tire
pressure warning light turns off. • 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.
• The “Tire Pressure Low - Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the tire pressure of all tires (except the spare) on the vehicle in-
formation display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position. For additional information, see “Low tire
pressure warning light” (P. 2-13), “Tire Pres-
sure Monitoring System (TPMS)” (P. 6-3) and
“Tire pressure” (P. 8-29).

TPMS with Easy-Fill Tire Alert
When adding air to an under-inflated tire,
the TPMS with Easy-Fill Tire Alert provides
visual and audible signals outside the ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place theshif t lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not
operating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following
conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
• If the Easy-Fill Tire Alert does not oper- ate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low - Add Air” warning
appears in the vehicle information
display, one or more of your tires is
significantly under-inflated. The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-13),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5), and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
"Cold Tire Pressure" heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
• Most tires naturally lose air over
time.
• Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with Easy-Fill Tire Alert”
(P. 5-8).
WHEELS AND TIRES
Do-it-yourself8-29

If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
tional information, see “Checking tire
pressure” (P. 8-32).
Set the tire pressure to the normal
cold tire inflation pressure when the
vehicle speed or load is reduced.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.
WARNING
• Improperly inflated tires can
fail suddenly and cause an
accident. •
The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label.
Do not load your vehicle be-
yond this capacity. Overload-
ing your vehicle may result in
reduced tire life, unsafe operat-
ing conditions due to prema-
ture tire failure, or unfavorable
handling characteristics and
could also lead to a serious ac-
cident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components.
• Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level. •
Increase the cold tire inflation
pressure as indicated in
"Checking tire pressure"
(P. 8-32) when using the tires
specified by NISSAN above 100
mph (162 km/h) where it is le-
gal to do so (on a race track for
example). Failure to increase
the cold tire inflation pressure
may result in tire failure, loss of
control and possible injury. Af-
ter such use, readjust tire
pressure.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty

Checking tire pressure
1. Remove the valve stem cap fromthe tire.
2. Press the pressure gauge squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will es-
cape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage. 3. Remove the gauge.
4. Read the tire pressure on the
gauge stem and compare to the
specification shown on the Tire
and Loading Information label.
5. Add air to the tire as needed. If too much air is added, press the core
of the valve stem briefly with the
tip of the gauge stem to release
pressure. Recheck the pressure
and add or release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.
