TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, 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 more details, refer to “Low tire pressure
warning light” in the “2. Instruments and con-
trols” section, “Tire pressure monitoring system
(TPMS)” in the “5. Starting and driving” section,
and “Flat tire” in the “6. In case of emergency”
section.
Tire inflation pressureCheck the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on 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 objects
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 after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.

Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING

Improperly inflated tires can fail
suddenly and cause an acci-
dent.

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. Overloading
your vehicle may result in re-
duced tire life, unsafe operating
conditions due to premature
tire failure, or unfavorable han-
dling characteristics and could
also lead to a serious accident.
Loading beyond the specifiedcapacity may also result in fail-
ure of other vehicle compo-
nents.

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.

Do not drive your vehicle over
85 MPH (137 km/h) unless it is
equipped with high speed rated
tires. Driving faster than 85
MPH (137 km/h) may result in
tire failure, loss of control and
possible injury.

Checking the tire pressure1. Remove the valve stem cap from the
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 escape. If the hissing sound
of air escaping from the tire is heard
while checking the pressure, reposi-
tion the gauge to eliminate this leak-
age.3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare it to the specifica-
tion 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. Re-
check 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.

WARNING

When changing or replacing tires, be
sure all four tires are of the same
type (i.e., Summer, All Season or
Snow) and construction. A NISSAN
dealer may be able to help you with
information about tire type, size,
speed rating and availability.

Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.

Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the tirepressure monitoring system (TPMS).

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tiresNISSAN specifies all season tires on some
models to provide good performance for use all
year round, including snowy and icy road condi-
tions. All season tires are identified by ALL
SEASON and/or M&S on the tire sidewall. Snow
tires have better snow traction than all season
tires and may be more appropriate in some
areas.Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.
Snow tiresIf snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some provinces and
states prohibit their use. Check local, state and
provincial laws before installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.

Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See “Specifications” in the “9. Tech-
nical and consumer information” section for rec-
ommended types and sizes of tires and wheels.
WARNING

The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.

If the wheels are changed for anyreason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
possibly degraded vehicle handling
characteristics and/or interference
with the brake discs/drums. Such in-
terference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear.

When a spare tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on after 1 minute. Contact your
NISSAN dealer as soon as possible
for tire replacement and/or system
resetting.

Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.

Do not install a deformed wheel or
tire even if it has been repaired. Suchwheels or tires could have structural
damage and could fail without warn-
ing.

The use of retread tire is not recom-
mended.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Wheel balanceUnbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.
