ECU INFINITI FX 2010 Repair Manual

Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Antifreeze
or equivalent.
CAUTION
●Do not substitute engine anti-freeze coolant
for window washer solution. This may result
in damage to the paint.
● Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water. ●
Keep the battery surface clean and dry.
Clean the battery with a solution 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 elec-
trical sparks. Hydrogen gas generated by
the battery is explosive. 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 con-
tacts your eyes, skin or clothing, immedi-
ately flush with water for at least 15 minutes
and seek medical attention.
● Do not operate the vehicle if the fluid in the
battery is low. Low battery fluid can cause a
higher load on the battery which can gener-
ate 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. ●
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash hands after handling.
● Keep the battery out of the reach of children.

Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating to
the original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on
all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires. Skid and traction capa-
bilities 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 install-
ing 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 clear-
ance. 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 re-
quired to accommodate the use of a winter
traction device (tire chains or cables). The mini-
mum clearances are determined using the fac-
tory equipped tire size. Other types may dam-
age your vehicle. Use chain tensioners when
recommended 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 underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, 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. Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause dam-
age to the various mechanisms of the vehicle
due to some overstress.

Steps for determining correct load
limit
1.Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs” on
your vehicle’s placard.
2.Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
3.Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4.The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the XXX
amount equals 1400 lbs. and there
will be five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs. (1400 750 (5 x 150) = 650
lbs) or (640 340 (5 x 70) = 300 kg.)
5.Determine the combined weight of
luggage 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 the cargo
area as shown. The tie down hooks can be used
to secure cargo with ropes or other types of
straps.
Do not apply a total load of more than 22 lb.
(98 N) to a single hook when securing cargo.
WARNING
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or shift-
ing. Do not place cargo higher than the seat-
backs. In a sudden stop or collision, unse-
cured cargo could cause personal injury.

●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 seriously 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 per-
sonal injury.
LOADING TIPS
●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 to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
●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 re-
sult in loss of control and cause per-
sonal injury.
●Overloading could not only shorten
the life of your vehicle and the tires,
but also could lead to hazardous ve-
hicle handling and long braking dis-
tance. This may cause a premature
tire malfunction, which could result in
a serious accident and personal in-
jury. Failures caused by overloading
are not covered by the vehicle’s
warranty.

MEASUREMENT OF WEIGHTS
Secure 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
weight ratings (GAWR). The total of the
axle loads should not exceed the gross
vehicle weight rating (GVWR). These rat-
ings are given on the vehicle certifica-
tion label. If weight ratings are ex-
ceeded, 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 performance and may lead to
accidents.
CAUTION
●Do not tow a trailer or haul a heavy load for
the first 500 miles (800 km). Your engine,
axle or other parts could be damaged.
● For the first 500 miles (800 km) that you tow
a trailer, do not drive over 50 MPH (80 km/h)
and do not make starts at full throttle. This
helps the engine and other parts of your ve-
hicle wear in at the heavier loads.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places additional
loads on your vehicle’s engine, drivetrain, steer-
ing, braking and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at
www.InfinitiUSA.com. This guide includes infor-
mation on trailer towing capability and the
special equipment required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the “Towing
Load/Specification” chart. The total trailer load
equals trailer weight plus its cargo weight.
● When towing a trailer load of 1,000 lbs (454
kg) or more, trailers with a brake system
MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following “Towing Load/Specification”
chart.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine INFINITI trailer hitch is avail-
able from an INFINITI retailer. Make sure the
trailer hitch is securely attached to the vehicle
to help avoid personal injury or property dam-
age due to sway caused by crosswinds, rough
road surfaces or passing trucks.
WARNING
Trailer hitch components have specific weight
ratings. Your vehicle may be capable of towing
a trailer heavier than the weight rating of the
hitch components. Never exceed the weight
rating of the hitch components. Doing so can
cause serious personal injury or property
damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:
● The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on top of the ball.
● Choose the proper class hitch ball based on
the trailer weight.
Technical and consumer information9-23
—
—
08/03/09—pattie


●The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should
be no more than 1/16 smaller than the hole
in the ball mount.
● The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Sway control device
Sudden maneuvers, wind gusts and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to
make sure the sway control device will work
with the vehicle, hitch, trailer and the trailer’s
brake system. Follow the instructions provided
by the manufacturer for installing and using the
sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lb
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lb
(1,588 kg).
CAUTION
● Special hitches which include frame rein-
forcements are required for towing above
2,000 lb (907 kg). Suitable genuine INFINITI
hitches for pickup trucks and sport utility
vehicles are available at an INFINITI retailer.
● The hitch should not be attached to or affect
the operation of the impact-absorbing
bumper.
● Do not use axle-mounted hitches.
● Do not modify the vehicle exhaust system,
brake system, etc. to install a trailer hitch.
● To reduce the possibility of additional dam-
age if your vehicle is struck from the rear,
where practical, remove the hitch and/or re-
ceiver when not in use. After the hitch is
removed, seal the bolt holes to prevent ex-
haust fumes, water or dust from entering the
passenger compartment.
● Regularly check that all trailer hitch mount-
ing bolts are securely mounted.
Tire pressures
●When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire and
Loading Information label.
●Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturers’ specifications.
Safety chains
Always use a suitable chain between your ve-
hicle and the trailer. The safety chains should
be crossed and should be attached to the hitch,
not to the vehicle bumper or axle. The safety
chains can be attached to the bumper if the
hitch ball is mounted to the bumper. Be sure to
leave enough slack in the chains to permit
turning corners.
