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 and clutch fluid” in
the “Maintenance and do-it-yourself” sec-
tion of this manual.
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) .

moved out of P (Park) and into any of
the other gear positions if the ignition
key is turned to the OFF position or if
the key is removed from the ignition
switch.
The starter is designed not to operate if
the shift selector lever is in any of the
driving positions.
Manual transmission:

(approximately 1/5 to the floor) and hold it
and then crank the engine. Release the
key and the accelerator pedal when the
engine starts.
cWhen the engine is very hard to start
because it is flooded, depress the accel-
erator pedal all the way to the floor and

Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft brush. Wipe the vinyl and leather
surfaces with a clean, soft cloth dampened in
mild soap solution, then wipe clean with a dry,
soft cloth. Before using any fabric protector, read
the manufacturer’s recommendations. Some fab-
ric protectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
CAUTION
cNever use benzine, thinner or any simi-
lar material.
cSmall dirt particles can be abrasive and
damaging to leather surfaces and
should be removed promptly. Do not
use saddle soap, polishes, oils, clean-
ing fluids, solvents, detergents or
ammonia-based cleaners as they may
damage the leather’s natural finish.
cNever use fabric protectors unless rec-
ommended by the manufacturer.
cDo not use glass or plastic cleaner on
meter or gauge lens covers. It may dam-
age the lens cover.
FLOOR MATS
The use of genuine NISSAN floor mats can ex-
tend the life of your vehicle carpet and make it
easier to clean the interior.No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation.Mats should be maintained
with regular cleaning and replaced if they be-
come excessively worn.
Floor mat positioning aid (driver’s side
only)
This vehicle includes a front floor mat bracket to
act as a floor mat positioning aid. NISSAN floor
mats have been specially designed for your ve-
hicle model. The driver’s side floor mat has a
grommet hole incorporated in it. Position the mat
by placing the floor mat bracket hook through the
floor mat grommet hole while centering the mat in
the footwell.
Periodically check to make certain the mats are
properly positioned.

Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Automatic transmission fluid level*Check
the level after putting the selector lever in P with
the engine idling at operating temperature.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
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 a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” 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 imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
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, deformation, rot or loose
connections.
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.

heater performance and engine overheat-
ing.

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.
