orBrake warning light
This light functions for both the parking
brake and the foot brake systems.
When the ignition key is in the ON position,
the light comes on when the parking brake
is applied, and also warns of a low brake
fluid level. If the light comes on while the
engine is running with the parking brake not
applied, stop the vehicle and perform the
following:
1.
Check the brake fluid level. Add brake fluid
as necessary. See ``Brake fluid'' in the
``Maintenance and do-it-yourself'' section
of this manual.
2. If the brake fluid level is correct, have the
warning system checked by an autho-
rized NISSAN dealer.
WARNING
cIf the level is below the MINIMUM or
MIN mark on the brake fluid reser-
voir, do not drive until the brake
system has been checked at an au-
thorized NISSAN dealer.cYour brake system may not be work-
ing properly if the warning light is
on. Driving could be dangerous. If
you judge it to be safe, drive care-
fully to the nearest service station
for repairs. Otherwise, have your ve-
hicle towed.
cPressing the brake pedal with the
engine stopped and/or a low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort as well as
pedal travel.
Charge warning light
If the light comes on while the engine is
running, it may indicate the charging system
is not functioning properly. Turn the engine
off and check the generator belt. If the belt is
loose, broken, or missing, or if the light
remains on, see an authorized NISSAN
dealer immediately.
CAUTION
Do not continue driving if the generator
belt is loose, broken or missing.
Door open warning light
This light comes on when any of the doors
are not closed securely while the ignition
key is ON.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop
the engineimmediatelyand call an autho-
rized NISSAN dealer.
The engine oil pressure warning light is
not designed to indicate a low oil level.
Use the dipstick to check the oil level.
See ``Engine oil'' in the ``Maintenance and
do-it-yourself'' section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine
as soon as it is safe to do so.

START: (4)
This position activates the starter motor,
which starts the engine.
NISSAN VEHICLE IMMOBILIZER
SYSTEM (NVIS) (if so equipped)
The Nissan Vehicle Immobilizer System
(NVIS) will not allow the engine to start
without the use of a registered NVIS key.
If the engine fails to start using a 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 start,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.
c
Check the operation of warning lights
when key is turned to the ON (3) position.

Installing the spare tire
The TEMPORARY USE ONLY spare tire
is designed for emergency use. See spe-
cific instructions under the heading
``Wheels and tires'' in the ``Maintenance
and do-it- yourself'' section of this own-
er's manual.
1. Clean any mud or dirt from the surface
between 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 wheelnuts alternately and evenly until they are
tight.
4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of flat tire,
etc.).
As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.
Wheel nut tightening torque:
80 ft-lb (108 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 lubrication interval.
Adjust tire pressure to the COLD
pressure.
COLD pressure:
After vehicle has been parked for three
hours or more or driven less than 1 mile
(1.6 km).
COLD tire pressures are shown on the
tire placard affixed to the driver's door
center pillar.
5.
With the spare tire installed on the vehicle,
place the damaged tire in the spare tire
storage area. Put the jack rod and wheel
nut wrench in the tool bag and place the
tool bag in the spare tire storage area.
6. Place the spare tire cover and the trunk
floor carpeting over the damaged tire.

you in choosing the proper product.
cWax your vehicle only after a thorough
washing. Follow the instructions supplied
with the wax.
cDo not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
cIf the surface does not polish easily, use
a ªroad tarº remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
Only use black wax or black shoe polish on
black urethane or polypropylene bumpers.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the surface of the paint to avoid lasting
damage or staining. Special cleaning prod-
ucts are available at an authorized NISSAN
dealer or any automotive accessory store.
UNDERBODY
In areas where road salt is used in winter,
the underbody must be cleaned regularly.
This prevents dirt and salt from building upand causing the acceleration of underbody
and suspension corrosion. Before winter
and again in the spring, the underseal must
be checked and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to become coated with a film
after the vehicle is parked in the hot sun.
Glass cleaner and a soft cloth easily remove
this film.
CAUTION
When cleaning the inside of the win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine based
disinfectant cleaners. They could dam-
age the electrical conductors, radio an-
tenna elements or rear window defog-
ger elements.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly, especially dur-
ing winter months in areas where road salt
is used. If not removed, road salt could
discolor the wheels.
CHROME PARTS
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain the
finish.

8-4Maintenance and do-it-yourself
ZX

Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rustmay form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift se-
lector lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cYour vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
