2006 NISSAN X-TRAIL service

E-85 fuelE-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square, or-
ange and black label with the common abbre-
viation or the appropriate percentage for that
region.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knockwhile holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oilIt is essential to choose the correct quality, and
viscosity oil to ensure satisfactory engine life and
performance. NISSAN recommends the use of a
low friction oil (energy conserving oil) in order to
improve fuel economy and conserve energy. Oils
which do not have the specified quality labelshould not be used as they could cause engine
damage.
Only those engine oils with the American Petro-
leum Institute (API) certification mark on the front
of the container should be used. This type of oil
supersedes the existing API SG, SH, or SJ and
Energy ConservingI&IIcategories.
If you cannot find engine oil with the API certifi-
cation mark, use an API grade SG, Energy
Conserving II or API grade SH, SJ or SL, Energy
conserving oil. An oil with a single designation
SG or SH, or in combination with other catego-
ries (for example, SG/CC or SG/CD) may also
be used if one with the API certification markcannot be found. An ILSAC grade, GF-II or
GF-III oil can also be used.
NISSAN recommends mineral based oils. These
oils must however, meet the API quality and SAE
viscosity ratings specified for your vehicle.
Oil additivesNISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.Oil viscosityThe engine oil viscosity or thickness changes
with temperature. Because of this, it is important
that the engine oil viscosity be selected based
on the temperatures at which the vehicle will be
operated before the next oil change. The recom-
mended SAE viscosity number chart shows the
recommended oil viscosities for the expected
ambient temperatures. Choosing an oil viscosity
other than that recommended could cause seri-
ous engine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-quality
genuine NISSAN oil filter. When replacing, use

the genuine oil filter or its equivalent for the
reason described in change intervals.Change intervalsThe oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than the
specified quality, or oil and filter change intervals
longer than recommended could reduce engine
life. Damage to engines caused by improper
maintenance or use of incorrect oil and filter
quality and/or viscosity is not covered by the
new NISSAN vehicle warranties.
Your engine was filled with a high quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle. Operation under
the following conditions may require more fre-
quent oil and filter changes.

repeated short distance driving at cold out-
side temperatures,

driving in dusty conditions,

extensive idling,

towing a trailer,

stop and go “rush hour” traffic,

aggressive driving.
RECOMMENDED SAE VISCOSITY
NUMBERSAE 5W-30 viscosity oil is preferred for all
ambient temperatures. SAE 10W-30,
10W-40 viscosity oil may be used if the
ambient temperature is above −18°C (0°F).
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
NISSAN A/C System Oil Type S or the
exact equivalents.
CAUTION
The use of any other refrigerant or lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner sys-
tem components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling of
any refrigerant during automotive air condition-
ing system service. Your NISSAN dealer has the
trained technicians and equipment needed to
recover and recycle your air conditioning system
refrigerant.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 805 km
(500 miles).

Have your vehicle serviced more often than at
intervals specified in the recommended main-
tenance schedule.

When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this, make
a larger than normal turning radius during the
turn.

Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help stabi-
lize the vehicle. Never increase speed.

Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal passing.Remember the length of the trailer must also
pass the other vehicle before you can safely
change lanes.

Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking ef-
ficiency.

Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.

Do not use cruise control while towing a
trailer.

Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 80
km (50 miles) of travel and at every break.

When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, the transmission
oil/fluid should be changed more fre-
quently. For additional information, see
the “8. Maintenance and do-it-yourself”
section earlier in this manual.
FLAT TOWINGTowing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a ve-hicle behind a recreational vehicle, such as a
motor home.
CAUTION

Failure to follow these guidelines
can result in severe transmission
damage.

Whenever flat towing your vehicle,
always tow forward, never backward.

DO NOT tow any automatic transmis-
sion vehicle with all four wheels on
the ground (flat towing). Doing so
WILL DAMAGE internal transmission
parts due to lack of transmission lu-
brication.

For emergency towing procedures re-
fer to “Towing Recommended by
NISSAN” in the “6. In case of emer-
gency” section of this manual.Automatic transmissionTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’sTechnical and consumer information

recommendations when using their product.Manual transmissionAll mode 4WD (four-wheel drive) models:
Never tow All mode 4WD models with any of the
wheels on the ground.DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.Traction AA, A, B and CThe traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.Temperature A, B and CTemperature grades are A (the highest), B, and
C. They represent a tire’s resistance to heat
build-up, and its ability to dissipate heat when
tested under controlled conditions on a speci-
fied indoor laboratory test wheel. Sustained high
temperature can cause tire material to degener-
ate, reducing tire life. Excessive temperatures
can lead to sudden tire failure. Grade C corre-
sponds to a performance level which all passen-
ger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A and
B represent higher levels of performance on
laboratory test wheels than the minimum re-
quired by law.

event, there is some important information you
should know. Many insurance companies rou-
tinely authorize the use of non-genuine collision
parts in order to cut costs, among other reasons.Insist on the use of Genuine NISSAN
Collision Parts!If you want your vehicle to be restored using
parts made to NISSAN’s original exacting speci-
fications — if you want to help it to last and holdits resale value, the solution is simple.Tell your
insurance agent and your repair shop to
only use Genuine NISSAN Collision Parts.
NISSAN does not warrant non-NISSAN parts,
nor does NISSAN’s warranty apply to damage
caused by a non-genuine part.
Using Genuine NISSAN Parts can help protect
your personal safety, preserve your warranty
protection and maintain the resale value of your
vehicle. And if your vehicle was leased, using
Genuine NISSAN Parts may prevent or limit
unnecessary excess wear and tear expenses at
the end of your lease.
NISSAN designs its hoods with crumple zones
to minimize the risk that the hood will penetrate
the windshield of your vehicle in an accident.
Non-genuine (imitation) parts may not provide
such built in safeguards. Also, non-genuine
parts often show premature wear, rust and cor-
rosion.
Why should you take a chance?In over 40 states and certain territories/
provinces, the law says you must be advised if
non-genuine parts are used to repair your ve-
hicle. And some states and provinces have
enacted laws that restrict insurance companies
from authorizing the use of non-genuine collision
parts during the new vehicle warranty. Theselaws help protect you, so you can take action to
protect yourself.
