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
1
and move the shoulder belt anchor to the
desired position
2, 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
shoulder belt guide with a clean, dry
cloth.
∙ 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
damage on the webbing is found, the
entire seat belt assembly should be re-
placed.
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, re-
lease 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 restraints
∙ Forward-facing child restraints
∙ Booster seats
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 improperly fit-
ting seat belt could cause serious or fa-
tal injury. Always use appropriate child
restraints.

The "CHECK TIRE PRES" warning message
”/”Tire Pressure Low— Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
For additional information, refer to “Tire
Pressure Monitoring System (TPMS)” in the
“Starting and driving” section and “Tire
pressure” in the “Do-it-yourself ” section of
this manual.
WARNING
∙ Radio waves could adversely affectelectric 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 location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal 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 Infor-
mation label located in the driver’s
door opening to turn the low tire pres-
sure warning light off. If the light still
illuminates while driving af ter adjust-
ing 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 in-
flated, have the vehicle checked. It is
recommended 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 pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main 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 affect
the proper operation of the TPMS.CAUTION
∙ The TPMS is not a substitute for theregular 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.

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously re-
duce the three-way catalyst’s ability
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 warming 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,
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 driving5-3

shoes and/or drums/rotors are replaced, in
order to assure the best braking performance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
∙ The ABS is a sophisticated device, butit 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 vehicle 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 infor-
mation” 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
distances.
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.
Starting and driving5-73

∙ When driving on extremely inclinedsurfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate. Do not drive on these
types of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or the
indicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
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 or the NISSAN
Intelligent Key®.
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
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, 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 to
provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. 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. 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.
