engine NISSAN X-TRAIL 2006 Manual PDF

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
NISSAN’s good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make sure that
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 the proper
maintenance care. You are a vital link in the
maintenance chain.SCHEDULED MAINTENANCEFor your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “Service and Mainte-
nance Guide”. You must refer to that guide to
ensure that necessary maintenance is performed
on your NISSAN at regular intervals.GENERAL MAINTENANCEGeneral maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for proper
vehicle operation. It is your responsibility toperform these procedures regularly as pre-
scribed.
Performing general maintenance checks require
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer, a
NISSAN dealer.
WHERE TO GO FOR SERVICEIf maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and tuned by a NISSAN dealer.
NISSAN technicians are well-trained specialists
and 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
vehiclesbeforethey 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 of your ve-
hicle — 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
smell, be sure to check for the cause or have a
NISSAN dealer check 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 ITEMSAdditional information on the following
items with “*” is found later in this section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors and the engine hood oper-
ate smoothly. Also make sure that all latches lock
securely. Lubricate if necessary. Make sure that
the secondary latch keeps the hood from open-
ing when the primary latch is released.
When driving in areas using road salt or other

the locks hold securely in all latched positions.
Steering wheel:
Check for changes in the steering conditions,
such as excessive free play, hard steering or
strange noises.
Warning lights and chimes:
Make sure that all warning lights and chimes are
operating properly.
Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in good quantity when
operating the heater or air conditioner.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel).
Battery*:
Check the fluid level in each cell. It should be
between the upper level and lower level lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.Brake and clutch fluid level*:
Make sure that the brake and clutch fluid level is
between the MAX and MIN lines on the reservoir.
Engine coolant level*:
Check the coolant level when the engine is cold.
Engine drive belts*:
Make sure that no belt is frayed, worn, cracked
or oily.
Engine oil level*:
Check the level on the dipstick after parking the
vehicle on a level spot and turning off the engine.
Exhaust system:
Make 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
locate the trouble and correct it. (See “Precau-
tions when starting and driving” in the “5. Start-
ing and driving” section for exhaust gas (carbon
monoxide).)
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.
Power steering fluid level* and lines:
Check the level in the reservoir tank with the
engine off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Radiator and hoses:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accumu-
lated. Make sure the hoses have no cracks,
deformation, deterioration or loose connections.
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.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.8-4

MAINTENANCE PRECAUTIONSWhen 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
the N(Neutral) position. For an auto-
matic transmission, move the selec-
tor lever to the P (Park) position.

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

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.

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 the
battery.
On gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, the fuel filter or fuel lines should
be serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is off.
CAUTION

Do not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.

Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.

Never leave any engine or automatic
transmission related component har-
ness connectors disconnected while
the ignition key is on.

Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-

The engine cooling system is filled at the factory
with a high-quality, year-round, antifreeze cool-
ant solution. The antifreeze solution contains rust
and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
WARNING

Never remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radiator.
Wait until the engine and radiator
cool down.

See “If your vehicle overheats” in the
“6. In case of emergency” section.

The radiator is equipped with a pres-
sure cap. To prevent engine damage,

WARNING

When engine is running, keep hands
and clothing away from any moving
parts such as fan drive belt.

Automatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
The fluid level should be checked using the HOT
range on the dipstick at fluid temperatures be-
tween 50 and 80°C (122 and 176°F) after the
vehicle has been driven approximately 5 minutes
in urban areas after the engine is warmed up.
The level can be checked at fluid temperatures
between 30 and 50°C (86 and 122°F) 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.If the vehicle has been driven for a long
time at high speeds, or in city traffic in hot
weather, or if it is being used to pull a
trailer, the fluid level cannot be read accu-
rately. You should wait until the fluid has
cooled down (about 30 minutes).
4. Remove the dipstick and 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.
