ECU NISSAN XTERRA 2010 Owner´s Manual

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, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector to
P (Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, 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 remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● If you must run the engine in an en-
closed 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 neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because 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 the engine off and
wait until it cools down.
● Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by a NISSAN dealer.

cally. Add windshield-washer fluid when the low
windshield-washer fluid warning light comes on.
To fill the windshield-washer fluid reservoir, lift
the cap off the reservoir tank and pour the win-
dow washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio.Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●
Do not substitute engine anti-freeze
coolant for windshield-washer solution.
This may result in damage to the paint.
● Do not fill the windshield-washer reser-
voir tank with washer fluid concen-
trates at full strength. Some methyl al-
cohol based washer fluid concentrates
may permanently stain the grille if
spilled while filling the windshield-
washer reservoir tank.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer reservoir
tank. Do not use the windshield-washer

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.
TIRE CHAINS
Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions.Use only SAE
class “S” chains. Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de-
signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required 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 tensioners
when recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of the
tire chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully load-
ing 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. Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emer-
gency” section in this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

5. Determine the combined weight ofluggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage load capacity of your vehicle.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
See “Measurement of Weights” later in
this section.
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion label.
SECURING THE LOAD
There are tie down hooks located in both the
ceiling and floor of the cargo area as shown. The
tie down hooks can be used to secure cargo with
ropes or other types of straps. See “Channel tie
down hooks” in this section.
Do not apply a total load of more than 110
lbs. (490 N) to a single metal ceiling tie-
down hook when securing cargo.
Do not apply a total load of more than 110
lbs. (490 N) to a single plastic floor tie-
down hook when securing cargo.WARNING
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.

Technical and consumer information9-15

●The child restraint top tether strap may
be damaged by contact with items in
the cargo area. Secure any items in the
cargo area. Your child could be seri-
ously injured or killed in a collision if
the top tether strap is damaged.
● Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of your
vehicle can break, tire damage could
occur, or it can change the way your
vehicle handles. This could result in
loss of control and cause personal
injury.
CHANNEL TIE-DOWN HOOKS (if so
equipped)
WARNING
●Properly install and tighten the tie-
down hooks into the channel system.
Also, do not install any rope or straps
directly to the channel. Failure to prop-
erly install the tie-down hooks or in-
stalling ropes or straps directly to the
channel can cause the cargo to become
unsecured. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury. ●
Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. In a sudden stop or collision,
unsecured cargo could cause personal
injury.
The adjustable channel tie-down hook system
allows you to move tie-down hooks in the cargo
area to the best location to secure a load.
The tie-down hooks must be installed so the hook
is properly fixed to the channel. If the tie-down
hook is not fixed to the channel it cannot be
properly tightened.
Check the tightness of the tie-down hooks peri-
odically during a trip to make sure they have not
become loose.
Install the tie-down hooks as follows: 1. Assemble 4 hook loops
Ato 4 hook plates
Bby screwing the hook plate onto the hook
(5 revolutions) .
