1-36Safety — Seats, seat belts and supplemental restraint system
sensor to turn the air bag OFF. Always be sure
to be seated and wearing the seat belt properly
for the most effective protection by the seat belt
and supplemental air bag.
The occupant classification sensor is designed
to operate as described above to turn the front
passenger air bag OFF for specified child
restraints. Failing to properly secure child
restrains and to use the ALR mode (child
restraint mode) may allow the restraint to tip or
move in an accident or sudden stop. This can
also result in the passenger air bag inflating in a
crash instead of being OFF. (See “Child
restraints” (P.1-18) for proper use and installa-
tion.)
If the front passenger seat is not occupied, the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object being detected by the occupant
classification sensor. Other conditions could
also result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle
occupants are seated and restrained properly.
Using the passenger air bag status light, you can
monitor when the front passenger air bag is
automatically turned OFF with the seat occu-pied. The light will not illuminate when the front
passenger seat is unoccupied.
If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF) , it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may
not be illuminated, depending on the size of the
child and the type of child restraint being used. If
the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash), it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated, try
a different child restraint.
If the passenger air bag status light will not
illuminate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF). Your NISSAN dealer can check that the
system is OFF by using a special tool. However,
until you have confirmed with your dealer that
your air bag is working properly, do not transporta child in this vehicle.
The NISSAN Advanced Air Bag System and
passenger air bag status light will take a few
seconds to register a change in the passenger
seat status. However, if the seat becomes
unoccupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
will blink. Have the system checked by a
NISSAN dealer.
Other supplemental front-impact air bag
precautions
WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause
injury if the front air bag inflates.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat that

CAUTION
.The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
. If the vehicle is being driven at
speeds of less than 16 MPH (25
km/h) , the TPMS may not operate
correctly.
. Be sure to install the specified size
of tires to the four wheels correctly.
Master warning light
When the ignition switch is in the ON position,
the master warning light illuminates if any of the
following are displayed on the vehicle informa-
tion display:
.No key warning
. Low fuel warning
. Low washer fluid warning
. Parking brake release warning
. Door/rear hatch open warning
. Loose fuel cap warning
See “Vehicle information display” (P.2-17) .
Seat belt warning light and chime
The light and chime remind you to fasten seat
belts. The light illuminates whenever the ignition
switch is pushed to the ON position, and will
remain illuminated until the driver’s seat belt is
fastened. At the same time, the chime will sound
for about 6 seconds unless the driver’s seat belt
is securely fastened.
The seat belt warning light for the front
passenger will illuminate if the seat belt is not
fastened when the front passenger’s seat is
occupied. For 5 seconds after the ignition
switch is in the ON position, the system does
not activate the warning light for the front
passenger.
See “Seat belts” (P.1-9) for precautions on seat
belt usage.
Supplemental air bag warning light
After pushing the ignition switch to the ON
position, the supplemental air bag warning light
will illuminate. The air bag warning light will turn
off after about 7 seconds if the front air bag, side
air bag and curtain air bag systems and/or
pretensioner system are operational.
If any of the following conditions occur, the front
air bag, side air bag and curtain air bag systems
and/or pretensioner system need servicing, and
your vehicle must be taken to your nearest NISSAN dealer.
.
The supplemental air bag warning light
remains on after approximately 7 seconds.
. The supplemental air bag warning light
flashes intermittently.
. The supplemental air bag warning light does
not come on at all.
Unless checked and repaired, the Supplemental
Restraint Systems and/or the pretensioner seat
belt may not function properly.
For additional information, see “Supplemental
restraint system” (P.1-28) .
WARNING
If the supplemental air bag warning
light is on, it could mean that the front
air bag, side air bag and curtain air bag
systems and/or pretensioner system
will not operate in an accident. To help
avoid injury to yourself or others, have
your vehicle checked by a dealer as
soon as possible.
Instruments and controls2-13

Predicted course lines*6:
Indicate the predicted course when backing up.
The predicted course lines will be displayed on
the monitor when the selector/shift lever is in the
R (Reverse) position and the steering wheel is
turned. The predicted course lines will move
depending on how much the steering wheel is
turned and will not be displayed while the
steering wheel is in the neutral position.
HOW TO PARK WITH PREDICTED
COURSE LINES
WARNING
. Always turn and check that it is safe
to park your car before backing up.
Always back up slowly.
. Use the displayed lines as a refer-
ence. The lines are highly affected
by the number of occupants, fuel
level, vehicle position, road condi-
tion and road grade.
. If the tires are replaced with differ-
ent sized tires, the predicted course
line may not be displayed correctly.
. On a snow-covered or slippery road,
there may be a difference between
the predicted course line and the actual course line.
. If predicted course lines are dis-
played incorrectly, drive the vehicle
on a straight road for 110 yd (100 m)
at a speed of above 20 MPH (30
km/h) .
. The displayed lines will appear
slightly off to the right because the
rearview camera is not installed in
the rear center of the vehicle.
. The distance guide line and the
vehicle width guide line should be
used as a reference only when the
vehicle is on a level paved surface.
The distance viewed on the monitor
is for reference only and may be
different than the actual distance
between the vehicle and displayed
objects.
. When backing up the vehicle up a
hill, objects viewed in the monitor
are further than they appear. When
backing up the vehicle down a hill,
objects viewed in the monitor are
closer than they appear. Use the
inside mirror or glance over your
shoulder to properly judge dis-
tances to other objects. The vehicle width and predicted course
lines are wider than the actual width and
course.

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.
— When replacing tires, install the
specified size of tires on all four
wheels.
— 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 “Tire and Loading
Information label” (P.9-13) of
this manual.
— For detailed information, see “Wheels and tires” (P.8-31) 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 system
Depress 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 feature
The 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 “clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and does notindicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h).
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.
Starting and driving5-27

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F(08C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, see “Engine
cooling system” (P.8-9).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery should
be checked regularly. For additional information,
see “Battery” (P.8-16) .
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “Engine cooling system”
(P.8-9) .
TIRE EQUIPMENT
SUMMER 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 “Tire
chains” (P.8-37) of this manual.
SPECIAL WINTER EQUIPMENT
It 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 ICE
WARNING
.Wet ice (328F, 0 8C 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 “grip” 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.

2. Loosen each wheel nut one or two turns byturning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground.
3. To lift the vehicle, securely hold the jack lever and rod with both hands as shown above.
Carefully raise the vehicle until the tire clears
the ground. Remove the wheel nuts, and
then remove the tire.
SCE0661
Installing the spare tire
The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading “Wheels and tires” (P.8-
31) .)
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight. Check that all the
wheel nuts contact the wheel surface
horizontally.
Models equipped with different sized
tires in the front and rear:
When replacing a front tire, make sure that

8-4Maintenance and do-it-yourself
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*:When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated, as the
front tires are a different size from the rear tires
and the direction of wheel rotation is fixed in
each tire.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
NISSAN Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism: On a fairly steep hill, check that your
vehicle is held securely with the selector lever in
the P (Park) position without applying any
brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, see a NISSAN dealer immediately. Keep
the floor mat away from the pedal.
Brakes:
Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
adjusted, see a NISSAN dealer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.

All season tires
NISSAN 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 tires
NISSAN 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 tires
If 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 CHAINS
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 “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” 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
Maintenance and do-it-yourself8-37

8-38Maintenance and do-it-yourself
tire chains in such conditions can cause damage
to the various mechanisms of the vehicle due to
some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this vehicle
because the front tires are a different size
than the rear tires.
A pin is on the front brake rotor to prevent
the rear wheels from being installed in
place of the front wheels. The spare tire
can be installed in place of the front and
rear wheels. When installing the spare tire
in the front wheel, the hole in the spare tire
wheel must be aligned with the pin on the
brake rotor.
WARNING
.Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or “Tire Safety Information” (Cana-
da) in the Warranty Information
