Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. For
additional information, refer to “Precau-
tions on seat belt usage” in this section. To
adjust, pull out the adjustment button
O1
and move the shoulder belt anchor to the
desired position
O2, so the belt passes over
the center of the shoulder. The belt should
be away from your face and neck, but not
falling off your shoulder. Release the ad-
justment button to lock the shoulder belt
anchor into position.
WARNING
• Af ter adjustment, release the adjust-
ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
• The shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may re-
duce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/
shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available for purchase. The ex-
tender adds approximately 8 in (200 mm)
of length and may be used for either the
driver or front passenger seating position.
It is recommended that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
• Only NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
• Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal injury
in the event of an accident.
• Never use seat belt extenders to in-
stall child restraints. If the child re-
straint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
• To clean the seat belt webbing, apply a
mild soap solution or any solution rec-
ommended for cleaning upholstery or
carpet. Then wipe with a cloth and allow
the seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
• If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der belt guide with a clean, dry cloth.

1-24Safety-Seats, seat belts and supplemental restraint system

•Periodically check to see that the seat
belt and the metal components, such
as buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes
tight. This can occur even if the vehicle
is parked. Unbuckle the seat belt to re-
lease the child. If the seat belt cannot
be unbuckled or is already unbuckled,
release the child by cutting the seat
belt with a suitable tool (such as a knife
or scissors) to release the seat belt.
Children need adults to help protect
them. They need to be properly re-
strained.
In addition to the general information in
this manual, child safety information is
available from many other sources, includ-
ing doctors, teachers, government traffic
safety offices, and community organiza-
tions. Every child is different, so be sure to
learn the best way to transport your child. There are three basic types of child re-
straint systems:
• Rear-facing child restraint
• Forward-facing child restraint
• Booster seat
The proper restraint depends on the child's
size. Generally, infants up to about 1 year
and less than 20 lbs. (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for chil-
dren who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle
lap/shoulder belt on a child who can no
longer use a forward-facing child restraint.
WARNING
Infants and children need special pro-
tection. The vehicle's seat belts may
not fit them properly. The shoulder belt
may come too close to the face or neck.
The lap belt may not fit over their small
hip bones. In an accident, an improp-
erly fitting seat belt could cause serious
or fatal injury. Always use appropriate
child restraints.

WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the light does not illuminate with
the ignition switch placed in the ON
position, have the vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
• If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle
speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as
possible. 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 acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter adjusting the tire
pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a spare
tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service.
• When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.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.
Low windshield-washer
fluid warning light (if so
equipped)
This light comes on when the windshield-
washer fluid is at a low level. Add
windshield-washer fluid as necessary. For
additional information, refer to “Windshield-
washer fluid” in the “Do-it-yourself ” section
of this manual.

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
• 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,
Starting and driving5-3

•Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, refer to
“Wet brakes” in this section.
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
• Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, refer to “Mainte-
nance under severe operating
conditions” in the “Maintenance and
schedules” section of this manual.
WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If
the engine stops while the vehicle is
being driven, this could lead to a crash
and serious injury. When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch position will illuminate as follows:
Push center:
• Once to change to ACC.
• Two times to change to ON.
• Three times to return to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.
The shif t lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the ignition switch cannot be moved
from the LOCK position.
Some indicators and warnings for opera-
tion are displayed in the meter. For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section of
this manual.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances 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 ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect 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. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer in-
formation” section of this manual.
– For additional information, refer
to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The 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 pre-
vent 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
Anti-lock Braking System 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 Anti-lock Braking System (ABS) in-
cludes 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 not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob (if so equipped).
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during ex-
tremely 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, refer to “Battery” in the “Do-it-
yourself ” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing 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.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself ” section 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 re-move 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 snow- drif ts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C 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” un-
der 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-
shif ting too fast, the drive wheels will
lose even more traction.
