NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS)
The Nissan Vehicle Immobilizer System
(NVIS) will not allow the engine to run
without the use of the registered NVIS key.
If the engine fails to run using the registered
NVIS key, it may be due to interference
caused by another NVIS key, an automated
toll road device or automated payment de-
vice on the key ring. Restart the engine
using the following procedures:
1. Leave the ignition switch in the ON posi-
tion for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately 5
seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while holding the de-
vice (which may have caused the inter-
ference) separate from the registered
NVIS key.If this procedure allows the engine to run,
NISSAN recommends placing the regis-
tered NVIS key on a separate key ring to
avoid interference from other devices.cMake sure the area around the vehicle is
clear.
cMaintenance items listed here should be
checked periodically, for example, each
time you check engine oil.
cCheck that all windows and lights are
clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers
to do likewise.
cCheck the operation of warning lights
when key is turned to the ON (3) position.

form the following procedure.
1. Turn the ignition key to the LOCK posi-
tion and remove the key.
2. Apply the parking brake.
3. Remove the shift lock release cover as
shown.
4. Insert a small screwdriver in the shift lock
release slot and push down.
5. Move the shift selector lever to the N
(neutral) position while holding down the
shift lock release.
6. Turn the key to the ON position to unlock
the steering wheel.
Now the vehicle may be moved to the
desired location.
If the lever cannot be moved out of P (Park),
have your authorized NISSAN dealer check
the automatic transmission system as soon
as possible.WARNING
If the selector lever cannot be moved
from the P (Park) position while the
engine is running and the brake pedal
is depressed, the stop lights may not
work. Malfunctioning stop lights could
cause an accident injuring yourself and
others.
Accelerator downshift Ð In D posi-
tion Ð
For passing or hill climbing, fully depress
the accelerator pedal to the floor. This shifts
the transmission down into second gear or
first gear, depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, the
next time the key is turned to the ON
position, the light in the instrument cluster of
the selected shift position will blink for ap-
proximately 8 seconds after the ignition is
turned ON. While the vehicle can be driven
under these circumstances, please note
that the gears in the automatic transmission
will be locked in third gear.
If the vehicle is driven under extremeconditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
This will occur even if all electrical cir-
cuits are functioning properly. In this
case, turn the ignition key OFF and wait
for 3 seconds. Then turn the key back to
the ON position. The vehicle should re-
turn to its normal operating condition. If
it does not return to its normal operating
condition, have your NISSAN retailer
check the transmission and repair if nec-
essary.
MANUAL TRANSMISSION
WARNING
cDo not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
cDo not over-rev the engine when
shifting to a lower gear. This may
cause a loss of control or engine
damage.

vehicle at a set speed.
cIn heavy traffic or in traffic that var-
ies in speed.
cOn winding or hilly roads.
c
On slippery roads (rain, snow, ice, etc.).
cIn very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
CAUTION
On manual transmission models, do
not shift into N (Neutral) without de-
pressing the clutch pedal when the
cruise control is set. Should this occur,
depress the clutch pedal and turn the-
main switch off immediately. Failure to
do so may cause engine damage.
CRUISE CONTROL OPERA-
TIONS

WARNING
cThe traction control system is de-
signed to help improve driving sta-
bility but does not prevent accidents
due to abrupt steering operation at
high speeds or by careless or dan-
gerous driving techniques. Reduce
vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always
drive carefully.
cIf suspension parts such as shock
absorbers, struts, springs and bush-
ings are not standard equipment or
are extremely deteriorated, the trac-
tion control off indicator light may
come on.
cWhen driving on extremely inclined
surfaces such as higher banked cor-
ners, the traction control system
may not operate properly or the
indicator light may come on.
Do not drive on these types of roads.cIf tires other than the recommended
ones are used, the traction control
system may not operate properly or
the
indicator light may come on.
cThe traction control 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 or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore 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'' 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 ``Maintenance
and do-it-yourself '' section.

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear, disc-type brakes self-
adjust every time the brake pedal is applied.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide.''
BRAKE BOOSTER
Check the brake booster function as fol-
lows:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedal
application to the next, continue on to the
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keep the pedal depressed for
about 30 seconds. The pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, see an
authorized NISSAN dealer.
CHECKING CLUTCH PEDAL
Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see an authorized NISSAN dealer.

ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher amperage
rating than specified on the fuse box
cover. This could damage the electrical
system or cause a fire.
If the electrical equipment does not come
on, check for an open fuse.
1. Be sure the ignition switch and the head-
light switch are OFF.
2. Open the engine hood.3. Remove the fuse box cover.
4. Remove the fuse with the fuse puller
located in the passenger compartment
fuse box.
5. If the fuse is open, replace it with a new
fuse.
6. If a new fuse also opens, have the elec-
trical system checked and repaired by an
authorized NISSAN dealer.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine NISSAN
parts.WDI0149

If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
Aftermarket fuel additives
NISSAN does not recommend the use of
any fuel additives (i.e.: fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain
active solvents or similar ingredients that
can be harmful to the fuel system and
engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index) num-
ber. However, you may use unleaded gaso-
line with an octane rating as low as 85 AKI
(Anti-Knock Index) number in high altitude
areas [over 4,000 ft (1,219 m)] such as:
Colorado, Montana, New Mexico, Utah,Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and the part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.''
(``Spark knock'' is a metallic rapping
noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy
spark knock even when using gasoline
of the stated octane rating, or if you hear
steady spark knock while holding a
steady speed on level roads, have an
authorized dealer correct the condition.
Failure to correct the condition is misuse
of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run or overheating, which may
cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle
checked at an authorized NISSAN dealer or
other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This isno cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
