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 all your tires as soon as
possible, and inflate them to the proper
pressure. 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 of all your tires is adjusted. Af ter
the 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
message is displayed in the odometer
when the low tire pressure warning light
is illuminated and low tire pressure is de-
tected. The “Tire Pressure Low - Add Air”
warning message turns off when the low
tire pressure warning light turns off. The
low tire pressure warning light remains
illuminated until the tires are inflated to
the recommended COLD tire pressure.
The “Tire Pressure Low - Add Air” warning
message is displayed each time the igni-
tion 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 is not displayed 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.
For additional information, see “Tire Pres-
sure Low - Add Air ” (P. 2-29) or “Low tire
pressure warning light” (P. 2-13) “Tire Pres-
sure Monitoring System (TPMS)” (P. 6-3).

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 (if so
equipped).
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 condi-
tions:
– If there is interference from an ex- ternal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire’s pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor 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.

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
warning is displayed in the odom-
eter, or the “Tire Pressure Low — Add
Air” appears in the vehicle informa- tion 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 af-
fixed to the driver side center pillar.

Tire pressures should be checked
regularly because:
• Most tires naturally lose air overtime.
• 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 tires
to the recommended COLD tire
pressure. For additional information,
see “TPMS with Easy-Fill Tire Alert”
(P. 5-8). 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 result 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.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Spare tire (TEMPORARY USE ONLY
spare tire)
When using a wheel without the TPMS such
as the spare tire, the TPMS will not function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
WARNING
• The spare tire should be used for
emergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
• Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
• Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY spare
tire at 420 kPa, 4.2 bar (60 psi).
• With the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle
at speeds faster than 50 mph (80
km/h). •
When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used
on the front wheels (drive wheels).
• Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
• Do not use the spare tire on other
vehicles.
• Do not use more than one spare tire
at the same time.
• Do not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
• Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not
drive the vehicle through an auto-
matic car wash since it may get
caught.
