2. If the brake fluid level is correct, have the
brake system checked by a NISSAN dealer.
WARNING
cYour brake system may not be working
properly if the warning light is on. Driv-
ing could be dangerous. If you judge it
to be safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because driv-
ing it could be dangerous.
cPressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
cIf the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at a
NISSAN dealer.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see a 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 in the ON
position.
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 engine
immediatelyand call a 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” sec-
tion of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
Low fuel warning light
This light comes on when the fuel level in the fuel
tank is getting low. Refuel as soon as it is conve-
nient, preferably before the fuel gauge reaches E
(Empty) .There will be a small reserve of fuel
in the tank when the fuel gauge needle
reaches E (Empty) .
Low tire pressure warning light
(if so equipped)
This light warns of low tire pressure.
Flat tire warning
If the vehicle is being driven with very low tire
pressure (lower than 27 psi, 190 kPa) , the light
will illuminate and the chime will sound for about
10 seconds.
For additional information, see “Low tire pressure
warning system” in the “Starting and driving”
section and “Flat tire” in the “In case of emer-
gency” section.
WARNING
cIf the light does not come on with the
key switch turned ON, have the vehicle
checked by a NISSAN dealer as soon as
possible.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For automatic transmission mod-
els, move the selector lever to P (Park) .
cBe sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
cNever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage.If in doubt about any servicing,
have it done by a NISSAN dealer.

CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
cNever remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
cAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
cKeep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Start the engine and let it idle until it reaches
operating temperature.3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re-
insert it all the way.
5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marks. This is the normal operating
oil level range. If the oil level is below the L
(Low) mark, remove the oil filler cap and pour
recommended oil through the opening.Do
not overfill.

cavoid full throttle driving and abrupt accelera-
tion
However, for maximum vehicle perfo-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION
cUsing a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
cUnder no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
For additional information, see “Capacities and
recommended fuel/lubricants in the “Technical
and consumer information” section.
RECOMMENDED ENGINE OIL:
cAPI Certification Mark
cAPI grade SG/SH Energy ConservingI&IIor
API grade SJ or SL Energy Conserving
cILSAC grade GF-1, GF-II & GF-III
c5W-30 Viscosity preferred
