the vehicle attains the speed you desire, re-
lease the switch.
cPush and release the RES/ACCEL switch.
Each time you do this, the set speed increases
by about 1 MPH (1.6 km/h) .
To reset at a slower cruising speed,use one
of the following three methods.
cLightly tap the brake pedal. When the vehicle
attains the desired speed, push the
COAST/SET switch and release it.
cPush and hold the SET/COAST switch. Re-
lease the switch when the vehicle slows to the
desired speed.
cPush and release the SET/COAST switch.
Each time you do this, the set speed de-
creases by about 1 MPH (1.6 km/h) .
To resume the preset speed,push and re-
lease the RES/ACCEL switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .During the first 1,200 miles (2,000 km) , follow
these recommendations to obtain maximum en-
gine performance and ensure the future reliability
and economy of your new vehicle. Failure to
follow these recommendations may result in
shortened engine life and reduced engine perfor-
mance.
cAvoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
cDo not accelerate at full throttle in any gear.
cAvoid quick starts.
cAvoid hard braking as much as possible.
cDo not tow a trailer for the first 500 miles (800
km) .cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other vehicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high gear
as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pressure.
Low tire pressure increases tire wear and low-
ers fuel economy.
cKeep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel economy.
Use the air conditioner only when necessary.
cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.

lem, but indicates that the system is functioning
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 consists of electronic
sensors and hydraulic solenoids controlled by 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 pulsa-
tion in the brake pedal. This is normal and is not
an indication 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 on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.
If a malfunction occurs in the system, the anti-
lock function will not operate, but the standard
vehicle brake system will continue to operate
normally. The ABS brake warning light will then
come on.
If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. 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 brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to “Tire plac-
ard” in the “Technical and consumer
information” section of this manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.

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.
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze (ethylene glycol base) 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 to
provide 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.
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When install-
ing tire chains, make sure they are ofproper 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 re-
stricted wheel well clearance. Vehicles
that can use Class “S” chains are de-
signed to meet the minimum clearances
between the tire and the closest vehicle
suspension or body component required
to accommodate the use of a winter trac-
tion device (tire chains or cables) . The
minimum clearances are determined us-
ing the factory equipped tire size. 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 possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when us-
ing tire chains. In addition, drive at a re-
duced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected.
Never install tire chains on spare tires. Do
not use tire chains on dry roads.

FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
cFailure to follow these guidelines can
result in severe transmission damage.
cWhenever flat towing your vehicle, al-
ways tow forward, never backward.
Automatic Transmission
CAUTION
cDO NOT tow any automatic transmis-
sion vehicle with all four wheels on the
ground (flat towing) . Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
cFor emergency towing procedures refer
to “Towing Recommended by Nissan”
earlier in this chapter.
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s

Your new NISSAN has been designed to have
minimum maintenance requirements with longer
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your NIS-
SAN’s good mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide.” You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration of the vehicle. They are essential if your
vehicle is to continue to operate properly. It is
your responsibility to perform these maintenance
procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hiclesbeforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*Check the pressure with a gauge at least
once a month 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.
