1-6Safety—Seats, seat belts and supplemental restraint system

●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 as-
sembly should be replaced. Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child.
There are three basic types of child restraint
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 children who outgrow rear-
facing child restraints 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 protec-
tion. 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 fitting seat belt
could cause serious or fatal injury. Always
use appropriate child restraints.
All U.S. states and Canadian provinces or terri-
tories require the use of approved child restraints
for infants and small children. See “Child re-
straints” later in this section.
A child restraint may be secured in the vehicle by
using either the LATCH (Lower Anchor and Teth-
ers for CHildren) system or with the vehicle seat
belt. See the “Child restraints” section for more
information.
NISSAN recommends that all pre-teens
and children be restrained in the rear seat.
Studies show that children are safer when
properly restrained in the rear seat than in
the front seat.
This is especially important because your
vehicle has a supplemental restraint sys-
tem (air bag system) for the front passen-
ger. See “Supplemental restraint system”
later in this section.

stop the vehicle and adjust the tire pressure to
the recommended COLD tire pressure shown on
the Tire and Loading Information label. See “Low
tire pressure warning light” earlier in this section
and “Tire Pressure Monitoring System (TPMS)”
in the “Starting and driving” section.
Your vehicle may have two types of security sys-
tems:
● Vehicle security system
● NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
or trunk lid when the system is armed. It is not,
however, a motion detection type system that
activates when a vehicle is moved or when a
vibration occurs.

To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces. Remember that stop-
ping distances on slippery surfaces will be
longer than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways 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” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section 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 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 slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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 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 not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked by a NISSAN dealer.
Starting and driving5-25

When the VDC switch is used to turn off the
system, the VDC system still operates to prevent
one drive wheel from slipping by transferring
power to a non slipping drive wheel. The
indicator flashes if this occurs. All other VDC
functions are off and the
indicator will not
flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the off
position then back to the on position.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or both the
andindi-
cator lights may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and both the
and theindicator lights may
illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, both the
andindicator lights may illuminate. ●
When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
both the
andindicator
lights 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 may flash or
both the
andindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing 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 may flash or both
the
andindicator lights 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 inserting it into the key
hole or use the remote keyless entry function on
the Intelligent Key.
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and 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 maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. 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. 3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and 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 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 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” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
COLD WEATHER DRIVING
5-28Starting and driving

Always refer to the proper illustrations for the
correct placement and jack-up points for your
specific vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.1. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground.
2. Place the jack directly under the jack-up point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
Align the jack head between the two notches in the front or the rear as shown.
Also fit the groove of the jack head between
the notches as shown.
The jack should be used on firm and
level ground.
3. To lift the vehicle, securely hold the jack lever and rod with both hands. Carefully raise the
vehicle until the tire clears the ground. Re-
move the wheel nuts, and then remove the
tire.Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of this
manual.
1. Clean any mud or dirt from the surface be- tween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly as illustrated until
they are tight.

in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”) .

Other Tire-related Terminology
In addition to the many terms that are
defined throughout this section, Intended
Outboard Sidewall is (1) the sidewall that
contains a whitewall, bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same molding on the
other sidewall of the tire, or (2) the out-
ward facing sidewall of an asymmetrical
tire that has a particular side that must
always face outward when mounted on a
vehicle.
TYPES OF TIRES
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.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
All season tires
NISSAN specifies All Season tires on some mod-
els to provide good performance all year, includ-
ing snowy and icy road conditions. 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 tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced 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 have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed the maximum speed rating of the tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
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
