If the shift selector lever cannot be moved out of
P (Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector lever in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts between third
gear and Overdrive repeatedly. In this case, de-
press the Overdrive switch to turn the Overdrive
off. The O/D OFF indicator light in the instrument
panel comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
MANUAL TRANSMISSION
WARNING
cDo not downshift abruptly on slippery
roads. This may cause a loss of control.
cDo not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.

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 accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size forthe tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.Use only SAE Class “S”
chains.Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a winter
traction device (tire chains or cables) . The
minimum clearances are determined using
the factory equipped tire size. Other types
may damage your vehicle. Use chain ten-
sioners 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 possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Never install tire chains on spare tires. Do
not use tire chains on dry roads.

WARNING
cIf the low tire pressure warning light
flashes while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Serious vehicle
damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pressure
for all four tires and adjust the pressure
to the COLD tire pressure shown on the
tire placard. If you have a flat tire, re-
place it with a spare tire as soon as
possible.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Shift the manual transmission into R
(Reverse) , or the automatic transmission
into P (Park) .
WARNING
cThe transfer control lever must
be in the 2H, 4H or 4L position.
cDo not leave the transfer control lever in
the N (Neutral) position. Otherwise, the
vehicle could roll unexpectedly even if
the manual transmission is in any gear
or the automatic transmission is in the
P (Park) position. This could result in
serious personal injury or property
damage.
4. Turn off the engine.5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic

WARNING
cMake sure the parking brake is securely
applied and the manual transmission is
shifted into R (Reverse) , or the auto-
matic transmission into P (Park) .
cNever change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
cNever change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
cWhen a spare tire is mounted or a wheel
is replaced, the low tire pressure warn-
ing system will not function. Contact
your NISSAN dealer as soon possible

If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc. take the following steps.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause a ve-
hicle fire.
cTo avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
cDo not open the hood if steam is com-
ing out.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.3. If engine overheating is caused by climbing a
long hill on a hot day, run the engine at a fast
idle (approximately 1,500 r/min) until the
temperature gauge indicator returns to nor-
mal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time when the coolant
temperature is high.
7. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at a
NISSAN dealer.

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.
Doors, engine hood and tailgateCheck that
the doors, engine hood and tailgate operate
properly. Also ensure that all latches lock se-
curely. Lubricate hinges, latches, latch pins, roll-
ers and links as necessary. Make sure that the
secondary latch keeps the hood from opening
when the primary latch is released.

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
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.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors; therefore, additional
engine cooling system additives are not neces-
sary.
WARNING
cNever remove the radiator cap when the
engine is hot. Wait until the engine and
radiator cool down. Serious burns
could be caused by high pressure fluid
escaping from the radiator. See precau-
tions in “If your vehicle overheats”
found in the “In case of emergency”
section of this manual.
cThe radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.
