Low tire pressure warning lightGUID-198D6DCF-E9F3-4FE1-8C20-8D8063552643Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors 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.
After the ignition switch is pushed ON, this light
illuminates for about 1 second and turns off.
Low tire pressure warning:
GUID-D73A39BF-43C8-459F-9C24-47B7F579C407If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A CHECK TIRE PRESSURE warning also
appears in the vehicle information display.
When the low tire pressure warning light
illuminates, you should stop and adjust the tire
pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label. The low tire pressure warning
light does not automatically turn off when the tire
pressure is adjusted. After the tire is inflated to
the recommended 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 CHECK TIRE PRESSURE warning appearseach time the ignition switch is placed in the ON
position as long as the low tire pressure warning
light remains illuminated.

WARNING
.
If the light does not illuminate with
the ignition switch pushed ON, have
the vehicle checked by a NISSAN
dealer as soon as possible.
. If the light illuminates while driving,
avoid sudden steering maneuvers or abrupt braking, reduce vehicle
speed, pull off the road to a safe
location and stop the vehicle as
soon as possible. Driving with un-
der-inflated tires may permanently
damage the tires and increase the
likelihood of tire failure. Serious
vehicle damage could occur and
may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low
tire pressure warning light OFF. If
the light still illuminates while driv-
ing after adjusting the tire pressure,
a tire may be flat. If you have a flat
tire, replace it with a spare tire as
soon as possible.
. 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 the 1 minute. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.

5-4Starting and driving
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 combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indi-
cator 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, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale
after 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.
Additional informationGUID-F08D0811-1070-4649-89CE-0F3AF1BDE3F8.The TPMS does not monitor the tire
pressure of the spare tire.
. 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) .
. The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended 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 CHECK TIRE PRESSURE warning also
appears on the vehicle information display
when the low tire pressure warning light is
illuminated and low tire pressure is detected.
The CHECK TIRE PRESSURE warning
turns off when the low tire pressure warning
light turns off.
The CHECK TIRE PRESSURE warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains illumi-
nated.
The CHECK TIRE PRESSURE 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 operation
and the outside temperature. 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 in
low ambient temperature, check the tire
pressure for all four tires.
For additional information, see ªLow tire pres-
sure warning lightº (P.2-13) and ªTire Pressure
Monitoring System (TPMS)º (P.6-3) .
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possi-
ble. 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
accident and could result in serious
personal injury. Check the tire pres-
sure for all four tires. Adjust the tire

exceeds a certain level, the Brake Assist is
activated generating greater braking force than a
conventional brake booster even with light pedal
force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver's responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM (ABS)GUID-B7350BDF-8854-429A-B2F3-935BFC82FFF3
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness.
Ð When replacing tires, install the
specified size of tires on all four
wheels.
Ð When installing a spare tire, make sure that it is the proper
size and type as specified on the
Tire and Loading Information
label. See ªTire and Loading
Information labelº (P.9-13) of
this manual.
Ð For detailed information, see ªWheels and tiresº (P.8-30) of
this manual.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the systemGUID-5F8F3DF3-1213-44B2-819C-394D031FC9DBDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test featureGUID-7E716B57-87FA-4414-818C-3D591D470B85The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a ªclunkº noise and/or feel a pulsation in the
brake pedal. This is normal and does not

the engine block. Refill before operating the
vehicle. For details, see ªEngine cooling systemº
(P.8-8) .
TIRE EQUIPMENTGUID-ED78C8A3-07DD-4857-A808-AB61C42A0B88SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or icy
roads, NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four wheels.
Consult a NISSAN dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces 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.
Tire chains may be used. For details, see ªTire
chainsº (P.8-36) of this manual.
SPECIAL WINTER EQUIPMENTGUID-FFCFD728-8757-4ED4-B2B8-5725E4F7B286It is recommended that the following items be
carried in the vehicle during winter:
.A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades. .
A sturdy, flat board to be placed under the
jack to give it firm support.
. A shovel to dig the vehicle out of snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICEGUID-32C999F5-3E37-4462-A88C-8A1D1D2A89DA
WARNING
.Wet ice (328F, 08C and freezing rain) ,
very cold snow or ice can be slick
and very hard to drive on. The
vehicle will have much less traction
or ªgripº under these conditions. Try
to avoid driving on wet ice until the
road is salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.

TEM (TPMS)
GUID-798990E0-F0C8-4003-8F39-B9227314C28FThis 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
CHECK TIRE PRESSURE warning appears on
the vehicle information display, one or more of
your tires is significantly under-inflated. If the
vehicle is being driven with low tire pressure, the
TPMS will activate and warn you of it by the low
tire pressure warning light. This system will
activate only when the vehicle is driven at
speeds above 16 MPH (25 km/h) . For more
details, see ªWarning/indicator lights and audi-
ble remindersº (P.2-10) and ªTire Pressure
Monitoring System (TPMS)º (P.5-3) .
WARNING
.If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possi-
ble. 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
accident and could result in serious
personal injury. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD
tire pressure shown on the Tire and
Loading Information label to turn
the low tire pressure warning light
OFF. If the light still illuminates
while driving after adjusting the tire
pressure, a tire may be flat. If you
have a flat tire, replace it with a
spare tire as soon as possible.
. 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 ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. NISSAN recommends using only
NISSAN Genuine Emergency Tire Sealant provided with your vehicle
(for models equipped with the emer-
gency tire puncture repair kit) . Other
tire sealants may damage the valve
stem seal which can cause the tire
to lose air pressure. However, in-
jecting any tire liquid or aerosol tire
sealant, including the NISSAN
Emergency Tire Sealant, requires
the replacement of the TPMS sen-
sor in addition to repairing or repla-
cing the tire.

TOWING RECOMMENDED BY
NISSAN (except for NISMO models)
GUID-65B2F390-EBB8-4FBF-8FD4-945BDB884083NISSAN recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed truck as
illustrated.
CAUTION
.Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the
ground (forward or backward) , as
this may cause serious and expen- sive damage to the drivetrain. If it is
necessary to tow the vehicle with
the front wheels raised, always use
towing dollies under the rear
wheels.
. When towing rear wheel drive mod-
els with the front wheels on the
ground or on towing dollies: Push
the ignition switch to the ACC or ON
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device.
. If you have to tow manual transmis-
sion models with the rear wheels on the ground (if you do not use towing
dollies) or four wheels on the
ground:
Ð Push the ignition switch to the
ON position and turn off all
accessories.
Ð Always release the parking brake.
Ð Move the transmission shift le- ver to the N (Neutral) position.
Ð Observe the following restricted towing speeds and distances for
manual transmission models
only:
.Rear wheels on the ground:

All season tiresGUID-B2669784-76C5-43E8-8E16-E7F77F372F57NISSAN specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S (Mud and Snow) on the tire
sidewall. Snow tires have better snow traction
than All Season tires and may be more appro-
priate in some areas.
Summer tiresGUID-F3ED94EB-3952-42A0-831A-DC9822960777NISSAN specifies summer tires on some
models to provide superior performance on dry
roads. Summer tire performance is substantially
reduced in snow and ice. Summer tires do not
have the tire traction rating M&S on the tire
sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, NISSAN recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tiresGUID-4ABDD5F0-221F-4250-B31A-457D3FD59024If 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 notmatch the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you install snow tires, they must be the same
brand, construction and tread pattern on all four
wheels, and the same sizes as the original tires.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires. Skid and traction cap-
abilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires.
TIRE CHAINSGUID-B7455203-4D74-496B-95E8-37BFF7A69A2B
CAUTION
Tire chains/cables should not be in-
stalled on 19-inch size tires. Doing so
will cause damage to the vehicle. If you
plan to use tire chains/cables, you
should install 18-inch size tires on your
vehicle.
Use of tire chains may be prohibited according
to location. Check the local laws before instal-
ling tire chains. When installing tire chains, make sure they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer's suggestions.
Use only SAE
Class S chains. Class ªSº chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class ªSº chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component required
to accommodate the use of a winter traction
device (tire chains or cables) . The minimum
clearances are determined using the factory
equipped tire size. Other types may damage
your vehicle. Use chain tensioners when re-
commended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully
loading your vehicle when using tire chains. In
addition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with

GUID-81BCA095-E7D3-4CE2-A684-123FD1E1D09ATowing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle behind a recreational vehicle, such as a
motor home.
CAUTION
.Failure to follow these guidelines
can result in severe transmission
damage.
. Whenever flat towing your vehicle,
always tow forward, never back-
ward.
. DO NOT tow any automatic trans-
mission vehicle with all four wheels
on the ground (flat towing) . Doing
so WILL DAMAGE internal transmis-
sion parts due to lack of transmis-
sion lubrication.
. For emergency towing procedures
refer to ªTowing recommended by
NISSAN (except for NISMO mod-
els)º (P.6-19) of this manual.
AUTOMATIC TRANSMISSIONGUID-21032A3C-932E-4072-9667-FA2CAD191E8CTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly MUST
be placed under the towed vehicle's drive
wheels. Always follow the dolly manufacturer's
recommendations when using their product.
MANUAL TRANSMISSIONGUID-8F862C4B-4E77-46AF-A267-BB3D3E9E681A. Always tow with the manual transmission in
Neutral.
. Your vehicle speed should never exceed 70
MPH (112 km/h) when flat towing your
vehicle.
. After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause
damage to the transmission's internal parts.
GUID-847767A6-AC43-4068-BDF0-695D11D7EE17DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEARGUID-EBD3F3AF-74FA-4332-AA15-3B9E01A51FFFThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half (1
1/2) times as well on the government course as
a tire graded 100. The relative performance of
tires depends upon actual conditions of their
use, however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road char-
acteristics and climate.
TRACTION AA, A, B AND CGUID-77FAD5AD-8EC3-4E81-978B-00D40AD98203The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on spe-
cified government test surfaces of asphalt and
