2006 NISSAN X-TRAIL ECU

Keep the battery surface clean and dry. Any
corrosion should be washed off with a solu-
tion of baking soda and water.

Make certain the terminal connections are
clean and securely tightened.

If the vehicle is not to be used for 30 days or
longer, disconnect the (—) negative battery
terminal cable to prevent discharging it.
WARNING

Do not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15 min-
utes and seek medical attention.

Battery posts, terminals and related
accessories contain lead and leadcompounds. Wash hands after han-
dling.

Do not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-
tery which can generate heat, reduce
battery life, and in some cases lead
to an explosion.

When working on or near a battery,
always wear suitable eye protection
and remove all jewelry.

Keep the battery out of the reach of
children.
Check the fluid level in each cell. It should be
between the UPPER LEVEL
1
and LOWER
LEVEL
2
lines.
If the side of the battery is not visible, the
electrolyte level can be checked through each
filler opening as illustrated.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.

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.

HEADLIGHT AIMThe aim of the headlights may require adjust-
ment when replacing the headlight assembly or
when the vehicle’s front body has been repaired.
When the adjustment is required, follow these
procedures, or have them adjusted by a NISSAN
dealer.
Before performing the headlight aim adjustment:

Check the pressure of all tires for the correct
inflation pressure.

Check that the tools and spare tire are
stowed securely.
Check that the fuel and lubricants levels are
filled to correct capacities.

Unload all luggage and other items, which
may influence the vehicle’s height level.

Load a weight on the driver’s seat that is
equivalent to the weight of a driver.
Stopping the vehicle1. Park the vehicle on a level surface vertical to
the wall or screen to which the headlights will
be projected.
2. Move the vehicle close to the wall to deter-
mine the point P as shown in the illustration.The point P must be:
“H” is the distance between the headlight
center point to the level surface.
“W
L” is the distance between the left and
right headlight centers.
3. Mark point P on the wall or screen.
4. Back up the vehicle 5,000 mm (197.0 in,
16.4 ft) straight away from the wall or screen.
“L” is the distance between the wall or screen
to the vehicle’s front bumper.
5. Apply the parking brake.

between tires on the front and rear
axles which will cause excessive tire
wear and may damage the transmis-
sion, transfer case and differential
gears.

ONLY use spare tires specified for
each 4-wheel drive model.
If excessive tire wear is found, it is recommended
that all four tires be replaced with tires of the
same size, brand, construction and tread pat-
tern. The tire pressure and wheel alignment
should also be checked and corrected as nec-
essary. Contact a NISSAN dealer.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to some
overstress.
TIRE CHAINSUse 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 of proper size for the tires on yourvehicle 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
designed to meet the SAE standard 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 recom-
mended by the tire chain manufacturer 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
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.

Do not use the chains on dry roads.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to someoverstress.8-40

the vehicle. That weight may not safely
exceed the available cargo and lug-
gage 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 reduces
the available cargo and luggage 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.
LOADING TIPSThere are luggage hooks located in the
cargo area. The luggage hooks can beused to secure cargo with ropes or other
types of straps.

The GVW must not exceed GVWR or
GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification la-
bel.

Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
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
collision, unsecured cargo
could cause personal injury.

Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of yourvehicle can break, tire damage
could occur, or it can change
the way your vehicle handles.
This could result in loss of con-
trol and cause personal injury.

Overloading not only can
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
longer braking distances. This
may cause a premature tire fail-
ure which could result in a seri-
ous accident and personal in-
jury. Failures caused by
overloading are not covered by
the vehicle’s warranty.
PAYLOAD WEIGHT CAPACITYThe payload weight capacity is the maxi-
mum total weight of passengers, optional
equipment (air conditioning, trailer hitch,
etc.) and cargo that your vehicle is de-
signed to carry.

(1,040)MEASUREMENT OF WEIGHTSSecure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is loaded,
drive to a scale and weigh the front and
the rear wheels separately to determine
axle loads. Individual axle loads should
not exceed either of the gross axle weightratings (GAWR). The total of the axle
loads should not exceed the gross ve-
hicle weight rating (GVWR). These rat-
ings are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION

Do not tow a trailer or haul a heavy
load for the first 800 km (500 miles).
