tow INFINITI FX 2012 Service Manual

9-20Technical and consumer information
STI0541
The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load.
Towing loads greater than these or using
improper towing equipment could ad-
versely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced on very
steep grades or for low traction situations
(for example, on slippery boat ramps).
Temperature conditions can also affecttowing. For example, towing a heavy trailer
in high outside temperatures on graded
roads can affect engine performance and
cause overheating. The transmission high
fluid temperature protection mode, which
helps reduce the chance of transmission
damage, could activate and automatically
decrease engine power. Vehicle speed may
decrease under high load. Plan your trip
carefully to account for trailer and vehicle
load, weather and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. See
“If your vehicle over-
heats” (P.6-11) of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures are not covered by
INFINITI warranties.

Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load
between 10 to 15% of the total trailer load
within the maximum tongue load limits
shown in the following“Towing Load/
Specification” chart. If the tongue load
becomes excessive, rearrange cargo to
allow for proper tongue load.

MAXIMUM GROSS VEHICLE WEIGHT
(GVW)/MAXIMUM GROSS AXLE
WEIGHT (GAW)
The GVW of the towing vehicle must not
exceed the Gross Vehicle Weight Rating
(GVWR) shown on the F.M.V.S.S./C.M.V.S.S.
certification label. The GVW equals the
combined weight of the unloaded vehicle,
passengers, luggage, hitch, trailer tongue
load and any other optional equipment. In
addition, front or rear GAW must not
exceed the Gross Axle Weight Rating
(GAWR) shown on the F.M.V.S.S./C.M.V.S.
S. certification label. Towing capacities are calculated assuming
a base vehicle with driver and any options
required to achieve the rating. Additional
passengers, cargo and/or optional equip-
ment, such as the trailer hitch, will add
weight to the vehicle and reduce your
vehicle’s maximum towing capacity and
trailer tongue load.
The vehicle and trailer need to be weighed
to confirm the vehicle is within the GVWR,
Front GAWR, Rear GAWR, Gross Combined
Weight Rating (GCWR) and Towing capacity.
All vehicle and trailer weights can be
measured using platform type scales com-
monly found at truck stops, highway weigh
stations, building supply centers or sal-
vage yards.
To determine the available payload capa-
city for tongue load, use the following
procedure.
1. Locate the GVWR on the F.M.V.S.S./C.M.
V.S.S. certification label.
2. Weigh your vehicle on the scale with all of the passengers and cargo that are
normally in the vehicle when towing a
trailer.
3. Subtract the actual vehicle weight from the GVWR. The remaining amount is the
Technical and consumer information9-21

9-22Technical and consumer information
available maximum tongue load.
To determine the available towing capacity,
use the following procedure.
1. Find the GCWR for your vehicle on the “Towing Load/Specification” chart
found later in this section.
2. Subtract the actual vehicle weight from the GCWR. The remaining amount is the
available maximum towing capacity.
To determine the Gross Trailer Weight,
weigh your trailer on a scale with all
equipment and cargo, that are normally
in the trailer when it is towed. Make sure
the Gross trailer weight is not more than
the Gross Trailer Weight Rating shown on
the trailer and is not more than the
calculated available maximum towing ca-
pacity.
Also weigh the front and rear axles on the
scale to make sure the Front Gross Axle
Weight and Rear Gross Axle Weight are not
more than Front Gross Axle Weight and
Rear Gross Axle Weight on the F.M.V.S.S./C.
M.V.S.S. certification label. The cargo in the
trailer and vehicle may need to be moved
or removed to meet the specified ratings. Example:
.
Gross Vehicle Weight (GVW) as weighed
on a scale - including passengers,
cargo and hitch - 5,073 lb. (2,301 kg).
. Gross Vehicle Weight Rating (GVWR)
from F.M.V.S.S./C.M.V.S.S. certification
label - 5,301 lb. (2,404 kg).
. Gross Combined Weight Rating (GCWR)
from “Towing Load/Specification” chart
- 7,355 lb. (3,336 kg).
. Maximum Trailer towing capacity from
“ Towing Load/Specification” chart -
2,000 lb. (907 kg).
5,301 lb. (2,404 kg) GVWR
− 5,073 lb. (2,301 kg) GVW
= 228 lb. (103 kg) Available for tongue
weight
7,355 lb. (3,336 kg) GCWR
− 5,073 lb. (2,301 kg) GVW
= 2,282 lb. (1,035 kg) Capacity available for
towing
228 lb. (103 kg) / Available tongue weight
2,282 lb. (1,035 kg) Available capacity = 10 % tongue weight
The available towing capacity may be less
than the maximum towing capacity due to the passenger and cargo load in the
vehicle.
Remember to keep trailer tongue weight
between 10 to 15% of the trailer weight. If
the tongue load becomes excessive, re-
arrange the cargo to obtain the proper
tongue load. Do not exceed the 10 to 15%
tongue weight specification even if the
calculated available tongue weight is
greater than 15%. If the calculated tongue
weight is less than 10%, reduce the total
trailer weight to match the available
tongue weight.
Always verify that available capacities are
within the required ratings.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine INFINITI trailer hitch is
available from an INFINITI retailer. Make
sure the trailer hitch is securely attached to
the vehicle to help avoid personal injury or
property damage due to sway caused by
crosswinds, rough road surfaces or pas-
sing 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
Technical and consumer information9-23

9-24Technical and consumer information
of the ball.
. Choose the proper class hitch ball
based on the trailer weight.
. 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 buffet-
ing caused by other vehicles can affect
trailer handling. 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
reinforcements 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
damage if your vehicle is struck from the
rear, where practical, remove the hitch
and/or receiver when not in use. After
the hitch is removed, seal the bolt holes
to prevent exhaust fumes, water or dust
from entering the passenger compart-
ment.
. Regularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
.When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
.Trailer tire condition, size, loadrating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains
Always use a suitable chain between your
vehicle 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.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more than
15 milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.
See a reputable trailer retailer to obtain
the proper equipment and to have it
installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in hooking up trailer lights, contact an
INFINITI retailer or reputable trailer retailer.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is
properly installed.
WARNING
Never connect a trailer brake system directly
to the vehicle brake system.
Pre-towing tips
.
Be certain your vehicle maintains a level
position when a loaded or unloaded
trailer is hitched. Do not drive the
vehicle if it has an abnormal nose-up
or nose-down condition; check for
improper tongue load, overload, worn
suspension or other possible causes of
either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center of
gravity low. .
Load the trailer so approximately 60%
of the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every
time you attach a trailer to the vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
clearance is known.Trailer towing tips
In order to gain skill and an understanding
of the vehicle’ s behavior, you should
practice turning, stopping and backing up
in an area which is free from traffic.
Steering stability, and braking perfor-
mance will be somewhat different than
under normal driving conditions.
. Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a pin
or lock to prevent the coupler from
Technical and consumer information9-25

9-26Technical and consumer information
inadvertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moderate
speed. Some states or provinces have
specific speed limits for vehicles that
are towing trailers. Obey the local
speed limits.
. When backing up, hold the bottom of
the steering wheel with one hand.
Move your hand in the direction in
which you want the trailer to go. Make
small corrections and back up slowly. If
possible, have someone guide you
when you are backing up.
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so:
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the wheels
and applying the parking brake, transmis-
sion damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
. When going down a hill, shift into a
lower gear and use the engine braking
effect. When going up a long grade,
downshift the transmission to a lower
gear and reduce speed to reduce
chances of engine overloading and/or overheating.
. If the engine coolant rises to an
extremely high temperature when the
air conditioning system is on, turn off
the air conditioner. Coolant heat can be
additionally vented by opening the
windows, switching the fan control to
high and setting the temperature con-
trol to the HOT position.
. Trailer towing requires more fuel than
normal circumstances.
. Avoid towing a trailer for the first 500
miles (800 km).
. Have your vehicle serviced more often
than at intervals specified in the
recommended maintenance schedule
in the INFINITI Service and Maintenance
Guide.
. When making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
. Crosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be
prepared for possible changes in cross-
winds that could affect vehicle hand-

ling. If swaying does occur, firmly grip
the steering wheel, steer straight
ahead, and immediately (but gradually)
reduce vehicle speed. This combination
will help stabilize the vehicle. Never
increase speed.
Do the following if the trailer begins to
sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle.
.Do not correct trailer sway by steer-ing or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of
the road in a safe area.
3. Try to rearrange the trailer load so it is balanced as described earlier in this
section.
. Be careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than nor-
mal passing. Remember the length of
the trailer must also pass the other
vehicle before you can safely change
lanes. .
Down shift the transmission to a lower
gear for engine braking when driving
down steep or long hills. This will help
slow the vehicle without applying the
brakes.
. Avoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in
reduced braking efficiency.
. 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.
. Some states or provinces have specific
regulations and speed limits for vehi-
cles that are towing trailers. Obey the
local speed limits.
. Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
after 50 miles (80 km) 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 launching a boat, don’t allow the
water level to go over the exhaust tail
pipe or rear bumper. .
Make sure you disconnect the trailer
lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see the “8.
Maintenance and do-it-yourself” section
earlier in this manual.
FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle 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, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
Technical and consumer information9-27

9-28Technical and consumer information
.DO NOT tow an All-Wheel Drive (AWD)
vehicle with any of the wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
. For emergency towing procedures refer
to“Towing recommended by INFINITI”
(P.6-13) of this manual.
Automatic transmission
All-Wheel Drive (AWD) models:
Do not tow an AWD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an auto-
matic transmission, an appropriate vehicle
dolly MUST be placed under the towed
vehicle’s drive wheels. Alwaysfollow the
dolly manufacturer’ s recommendations
when using their product. DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature ATREADWEAR
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government 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 actual conditions of their use, how-
ever, 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 C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden
