and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-
tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion from the actuator under the hood. This
is normal and indicates that the anti-lock
system is working properly. However, the
pulsation may indicate that road conditions
are hazardous and extra care is required
while driving.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic 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 is not an indica-
tion of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the
ABS brake warning light in the dashboard.
The brake system then operates normally,
but without anti-lock assistance.
If the light comes on during the self check orwhile driving, take your vehicle to your NIS-
SAN dealer for repair at your earliest con-
venience.
WARNING
cThe anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces, but remember that the
stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock
system. 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 respon-
sibility for safety of self and others
rests in the hands of the driver.
cTire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.c
When installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the Owner's Manual
index.
cRefer to ``Wheels and tires'' in the
``Do-it-yourself operations'' section
of this manual.

Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole.
If the lock becomes frozen, heat the key
before inserting it into the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself operations'' section.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself
operations'' section.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself
operations'' section.
Tire equipment
1. SUMMER tires are of a tread design to
provide 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. Please consult your NIS-
SAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
provinces and states 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 if desired. Make
sure they are of proper size for the tires
on your vehicle and are installed accord-ing to the chain manufacturer's sugges-
tions.
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
of proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions.Use only
SAE Class ªSº chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility 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.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance in
snow and ice is substantially reduced. Sum-
mer 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'' 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 han-
dling of your vehicle.
Generally, snow tires have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-stalling studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Tire chains
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ªSº chains.
Other types may damage your vehicle. Use
chain tensioners when recommended 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 possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km).
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
As soon as possible, tighten the wheel
nuts to the specified torque with a nut
tightening torque:
72 to 87 ft-lb (98 to 118 Nzm)
The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation inter-
val.

cIf the wheels are changed for any
reason, always replace with
wheelswhich have the same offset
dimension. Wheels of a different off-
set could cause early tire wear, poor
vehicle handling characteristics
and/or interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
Care of wheels
cWash the wheels when washing the
vehicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
cInspect wheel rims regularly for dents or
corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (T-type spare tire)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident:
CAUTION
cThe T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the
first opportunity.cDrive carefully while the T-type
spare tire is installed. Avoid sharp
turns and abrupt braking while
driving.
cPeriodically check tire inflation pres-
sure, and always keep it at 60 psi
(420 kPa, 4.2 bar).
cDo not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
cDo not use tire chains on a T-type
spare tire. Tire chains will not fit
properly on the T-type spare tire and
may cause damage to the vehicle.
cWhen driving on roads covered with
snow or ice, the T-type spare tire
should be used on the rear wheel
and the original tire used on the front
wheels (drive wheels). Use tire
chains only on the front two original
tires.
cTire tread of the T-type spare tire will
wear at a faster rate than the original
tire. Replace the T-type spare tire as
soon as the tread wear indicators
appear.
