2006 NISSAN X-TRAIL service

requires coolant, have it checked by a
NISSAN dealer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.

Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

To avoid being scalded, never change
the coolant when the engine is hot.
Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.
1. Open radiator drain valve
Aat the bottom of
radiator, and remove radiator filler cap
B.

Be careful not to allow coolant to con-
tact drive belts.

Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain valve securely after
the coolant is drained.
3. Fill the radiator slowly with the proper mixture
of antifreeze solution and demineralized
water/distilled water. Fill the reservoir tank up
to the MAX level. Then install the radiator filler
cap.

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGSIf replacement is required, see a NISSAN dealer
for servicing.Platinum-tipped spark plugsIt is not necessary to replace the platinum-tippedAspark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance schedule, but do not
reuse them by cleaning or regapping.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the separate Service and Mainte-
nance Guide. When replacing the filter, wipe the
inside of the air cleaner housing and the cover
with a damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame

be followed.For additional information, see the
separate Service and Maintenance Guide.BRAKE BOOSTERCheck the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake pedal
movement (distance of travel) remains the
same from one pedal application to the next,
continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, see a
NISSAN dealer.Some vehicles are equipped with engine com-
partment and passenger compartment fuse
boxes that use only type
A
fuses. Other ve-
hicles are equipped with typeA
fuses in the
engine compartment fuse box and type
Bfuses
in the passenger compartment fuse box.
Type
Afuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type
A
fuses can be installed in the engine
compartment and passenger compartment fuse
boxes.If a type
A
fuse is used to replace a type
B
fuse, the type
A
fuse will not be level with the
fuse pocket as shown in the illustration. This will
not affect the performance of the fuse. Make
sure the fuse is installed in the fuse box securely.
Type
B
fuses cannot be installed in the under-
hood fuse boxes. Only use type
A
fuses in the
underhood fuse boxes.

the tire(s) should be replaced.

The original tires have a built-in
tread wear indicator. When the
wear indicators are visible, the
tire(s) should be replaced.

Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.

Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, contact a
NISSAN dealer.

For additional information re-
garding tires, refer to “Tire
Safety Information” in the War-
ranty Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING

The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.

If the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offsetcould cause premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to “Wheels and
Tires” in the “Technical and con-
sumer information” section of this
manual for wheel offset dimensions.

Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.

The use of retread tire is not recom-
mended.

For additional information regarding
tires, refer to “Tire Safety Informa-
tion” in the Warranty Information
Booklet.
Wheel balanceUnbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can

get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires, refer to
“Tire Safety Information” in the Warranty Infor-
mation Booklet.Care of wheels
Wash the wheels when washing the vehicle
to maintain their appearance.

Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.

Do not use abrasive cleaners when washing
the wheels.

Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.

NISSAN recommends waxing the road wheel
sidewalls to protect against road salt in areas
where it is used during winter.

FUEL RECOMMENDATIONUse unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION

Using a fuel other than that specified
could adversely affect the emission
control devices and systems, and
could also affect the warranty cover-
age.

Under no circumstances should a
leaded gasoline be used, since this
will damage the three-way catalyst.

Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run
on E-85 fuel. Using E-85 fuel can
damage the fuel system components
and is not covered by the NISSAN
vehicle limited warranty.Gasoline specificationsNISSAN recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-cations where it is available. Many of the auto-
mobile manufacturers developed this specifica-
tion to improve the emission control system and
vehicle performance. Ask your service station
manager if the gasoline meets the WWFC
specifications.
Reformulated gasolineSome fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.Gasoline containing oxygenatesSome fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your NISSAN cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please take
the following precautions as the usage of such
fuels may cause vehicle performance problems
and/or fuel system damage.

The fuel should be unleaded and have
an octane rating no lower than thatrecommended for unleaded gasoline.

If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are
suitable for use in NISSAN vehicles.
If any undesirable driveability problems such as
engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
