2003 NISSAN PATHFINDER automatic transmission

CAUTION

Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground,
as this may cause serious and expen-
sive damage to the transmission. If it
is necessary to tow the vehicle with
the front wheels raised, always use
towing dollies under the rear wheels.

When towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:

Move the transfer case shift lever
to the 2H position.

Turn the ignition key to the OFF
position, and secure the steering
wheel in a straight ahead position
with a rope or similar device. Never
secure the steering wheel by turn-
ing the ignition key to the LOCK
position. This may damage the
steering lock mechanism.
If you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the ground:

Move the transfer case shift lever
to the 2H position.

Move the transmission shift lever
to the N(Neutral) position.

Always release the parking brake.

Observe the following restricted tow-
ing speeds and distances manual
transmission models only:

Speed: Below 60 MPH (95 km/h)

Distance: Less than 500 miles (800
km)
If the speed or distance must necessarily be
greater, remove the front and rear propeller
shafts before towing to prevent damage to the
transmission.

confirm that your vehicle is held securely on a
fairly steep hill with only the parking brake ap-
plied.Automatic transmission P (Park) position
mechanism:
On a fairly steep hill check that your vehicle is
held securely with the selector lever in the P
position without applying any brakes.
Under the hood and vehicleThe maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. (Be sure to
wait a few minutes to allow the oil to drain back
into the sump.)
Brake and clutch fluid levels*:
Make sure that the brake and clutch fluid level is
between the MAX and MIN lines on the reservoir.
Power steering fluid level* and lines:
Check the level when the fluid is cold and the
engine is turned off. Check the lines for proper

ing and driving” section for exhaust gas (carbon
monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
Fluid leaks:
Check 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.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

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.

Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.

If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.

It is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.

Always wear eye protection when-
ever you work on your vehicle.

If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.

Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.

Keep smoking materials, flame and
sparks away from fuel and battery.

Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable be-
fore working near the fan.

TEMPERATURE CONDITIONS FOR
CHECKINGThe fluid level should be checked using the HOT
range (L & H marks) on the dipstick at fluid
temperatures between 122 and 176°F (50 and
80°C) after the vehicle has been driven approxi-
mately 5 minutes in urban areas after the engine
is warmed up. The level can be checked at fluid
temperatures between 86 and 122°F (30 and
50°C) using the COLD range on the dipstick for
reference, after the engine is warmed up but
before driving. However, the fluid level must be
rechecked using the HOT range.1. Park the vehicle on a level surface and set the
parking brake.
2. Start the engine and then move the selector
lever through each gear range, ending in P.
3. Check the fluid level with the engine idling.
4. Expand the spring stopper and remove the
dipstick. Wipe it clean with lint-free paper.
5. Re-insert the dipstick into the charging pipe
as far as it will go.
6. Remove the dipstick and note the reading.
If the level is on the low side of either range, add
fluid to the charging pipe.
7. When inserting the dipstick, set it so that the
spring stopper presses the upper part of the
dipstick rubber to lock the dipstick.
CAUTION

Do not overfill.

After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check all hitch mounting
bolts are securely mounted.

To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.

Never connect a trailer brake system
directly to the vehicle brake system.Tire pressures
When towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard (affixed to the glove
box lid).

Trailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturers’
specifications.Safety chains
Always use a suitable chain between your ve-
hicle and the trailer. The chain should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chain to permit turning
corners.Trailer lightsTrailer lights should comply with Federal and/or
local regulations.
When wiring vehicle for towing connection,
connect stop and tail light pickup into the
vehicle electrical circuit at point between
the sensor and stop light switch or light
switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to Federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Trailer towing tipsIn order to gain skill and an understanding of thevehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with automatic
transmission, first block the wheels and apply
the parking brake, and then move the trans-
mission selector lever into the P position. If
you move the selector lever to the P position
before blocking the wheels and applying the
parking brake, transmission damage could
occur.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.
