AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFC-134a (R-134a) and the oil, Genuine
NISSAN A/C System Oil Type ND-OIL8 or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle does not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive air conditioner system service. An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner
system.

WARNING
∙ It is extremely dangerous to ride in a cargo area inside a vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
∙ Do not allow people to ride in any area of your vehicle that is not
equipped with seats and seat
belts.
∙ Be sure everyone in your vehicle is in a seat and using a seat belt
properly.
TERMS
It is important to familiarize yourself
with the following terms before load-
ing your vehicle:
∙ Curb Weight (actual weight of your vehicle) - vehicle weight in-
cluding: standard and optional
equipment, fluids, emergency
tools, and spare tire assembly. This
weight does not include passen-
gers and cargo. ∙ GVW (Gross Vehicle Weight) -
curb weight plus the combined
weight of passengers and cargo.
∙ GVWR (Gross Vehicle Weight Rat- ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label.
∙ GAWR (Gross Axle Weight Rating) - maximum weight (load) limit
specified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label.
∙ GCWR (Gross Combined Weight rating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer. ∙ Vehicle Capacity Weight, Load
limit, Total load capacity - maxi-
mum total weight limit specified of
the load (passengers and cargo)
for the vehicle. This is the maxi-
mum combined weight of occu-
pants and cargo that can be
loaded into the vehicle. If the ve-
hicle is used to tow a trailer, the
trailer tongue weight must be in-
cluded as part of the cargo load.
This information is located on the
Tire and Loading Information la-
bel.
∙ Cargo capacity - permissible weight of cargo, the subtracted
weight of occupants from the load
limit.
VEHICLE LOADING INFORMATION
10-14Technical and consumer information

Steps for determining correct load
limit
1. Locate the statement “The com-bined weight of occupants and
cargo should never exceed XXX
lbs. or XXX kg” on your vehicle’s
Tire and Loading Information la-
bel.
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 lbs. or XXX kg.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For ex-
ample, if the XXX amount equals
1,400 lbs. and there will be five
150 lbs. passengers in your ve-
hicle, the amount of available
cargo and luggage load capacity
is 650 lbs. (1,400-750 (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 transferred 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, con-
firm that you do not exceed the GVWR
or the GAWR for your vehicle. For ad-
ditional information, refer to “Mea-
surement of weights” in this section.
Also check tires for proper inflation
pressures. For additional information,
refer to “Tire and Loading Information
label” in the “Do-it-yourself” section of
this manual.
SECURING THE LOAD
There are luggage hooks located in the cargo
area as shown. The hooks can be used to
secure cargo with ropes or other types of
straps.
When securing items using luggage hooks
located on the side finisher do not apply a
load over more than 6.5 lbs. (29 N) to a single
hook.
The luggage hooks that are located on the
floor should have loads less than 110 lbs.
(490 N) to a single hook.

Tow Hitch Receiver (with Tow Package)
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 loadfor the first 500 miles (805 km). Your
engine, axle or other parts could be
damaged. ∙ For the first 500 miles (805 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 vehicle 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 addi-
tional loads on your vehicle’s engine, drive
train, steering, braking and other systems.
An INFINITI Towing Guide (U.S. only) is avail-
able on the website at www.InfinitiUSA.com.
This guide includes information on trailer
towing capability and the special equipment
required for proper towing. Lifestyle Receiver (without Tow Package)
WARNING
The Lifestyle Receiver cannot be used for
towing a trailer. Only use the Lifestyle Re-
ceiver for receiver mounted accessories
that meet the below requirements.
∙ The maximum allowable load is 300 lbs.
(136 kg) including the weight of the in-
stalled accessory carrier.
∙ Do not exceed allowable cargo weight capacity of your vehicle.
Failure to use the Lifestyle Receiver as in-
tended can result in serious injury or death.

TOWING A TRAILER
10-18Technical and consumer information

CAUTION
If your vehicle is equipped with the Lifestyle
Receiver to avoid damage to your vehicle
do not tow a trailer with your vehicle.
Do not tow a trailer with your vehicle with the
Lifestyle Receiver (if so equipped). The Life-
style Receiver should be used for receiver-
mounted accessories only. The Lifestyle Re-
ceiver is designed for carrying bikes, snow
boards/skis, camping gear and various other
bulky items.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart found in this sec-
tion. The total trailer load equals trailer
weight plus its cargo weight.
The maximum Gross Combined Weight Rat-
ing (GCWR) should not exceed the value
specified in the following Towing
Load/Specification Chart. 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 adversely affect ve-
hicle 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 for low traction situ-
ations (for example, on slippery boat ramps).
Temperature conditions can also affect tow-
ing. For example, towing a heavy trailer in
high outside temperatures on graded roadscan affect engine performance and cause
overheating. The engine protection mode,
which helps reduce the chance of engine
damage, could activate and automatically
decrease engine power. Vehicle speed may
decrease under high load. Plan your trip care-
fully 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 colli-
sion. 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. For additional informa-
tion, refer to “If your vehicle overheats” in
the “In case of emergency” section of this
manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
INFINITI warranties.

Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 - 15% of the total trailer load or use
the trailer tongue load specified by the trailer
manufacturer. The tongue load must be
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 com-
bined weight of the unloaded vehicle, pas-
sengers, luggage, hitch, trailer tongue load
and any other optional equipment. In addi-
tion, 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 re-
quired to achieve the rating. Additional pas-
sengers, cargo and/or optional equipment,
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 mea-
sured using platform type scales commonly
found at truck stops, highway weigh stations,
building supply centers or salvage yards.
To determine the available payload capacity
for tongue/king pin 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
available maximum tongue/king pin
load.
WTI0160LTI2031
10-20Technical and consumer information

To determine the available towing capacity,
use the following procedure.1. Find the GCWR for your vehicle on the "Towing Load/Specification" chart
found 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 tow-
ing capacity.
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 rat-
ings.
Example: ∙ Gross Vehicle Weight (GVW) as weighed
on a scale - including passengers, cargo
and hitch - 4,650 lbs. (2,109 kg).
∙ Gross Vehicle Weight Rating (GVWR) from F.M.V.S.S./C.M.V.S.S. certification
label - 4,916 lbs. (2,230 kg).
∙ Gross Combined Weight Rating (GCWR) from “Towing Load/Specification" chart
- 7,320 lbs. (3,320 kg).
∙ Maximum Trailer towing capacity from “Towing Load/Specification" chart -
3,000 lbs. (1,361 kg).4,916 lbs. (2,230 kg) GVWR

266 lbs. (121 kg) Available tongue weight
= 2,670 lbs. (1,211 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 be-
tween 10 - 15% of the trailer weight or within
the trailer tongue load specification recom-
mended by the trailer manufacturer. If the
tongue load becomes excessive, rearrange
the cargo to obtain the proper tongue load.
Do not exceed the maximum tongue weight
specification shown in the “Towing
Load/Specification” chart even if the calcu-
Technical and consumer information10-21

lated 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 LOAD/SPECIFICATION
WARNING
The towing capacities provided in this
manual are for general reference only. The
safe towing capacity of your vehicle is af-
fected by dealer and factory installed op-
tions and passenger and cargo loads. You
must weigh the vehicle and trailer as de-
scribed in this manual to determine the ac-
tual vehicle towing capacity. Do not exceed
the published maximum towing capacity or
the GCWR or the GVWR shown on the

TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an op-
tional trailer tow package. The trailer tow
package includes a receiver-type frame
mounted hitch. This hitch is rated for the
maximum towing capacity of this vehicle
when the proper towing equipment is used.
Choose a proper ball mount and hitch ball
that is rated for the trailer to be towed. Genu-
ine INFINITI ball mounts and hitch balls are
available from an INFINITI retailer.
If your vehicle is not equipped with the op-
tional trailer tow package, check the towing
capacity of your bumper hitch or receiver-
type frame mounted 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 sur-
faces 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 ex-
ceed the weight rating of the hitch compo-
nents. 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 the top 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.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the hitch
receiver. Choose a proper class ball mount
based on the trailer weight. Additionally, the
ball mount should be chosen to keep the
trailer tongue level with the ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on the
receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer to
distribute the tongue weight (hitch weight) of
your trailer. Many vehicles can’t carry the full
tongue weight of a given trailer, and need
some of the tongue weight transferred
through the frame and pushing down on the
front wheels. This gives stability to the tow
vehicle.
A weight-distributing hitch system (Class IV)
is recommended if you plan to tow trailers
with a maximum weight over 5,000 lbs.
Technical and consumer information10-23

(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the surge
brake, hitch or trailer manufacturer to de-
termine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:1. Park unloaded vehicle on a level surface. With the ignition on and the doors
closed, allow the vehicle to stand for
several minutes so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea- sured in step 2. The rear bumper should
be no higher than the reference height
measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no higher
than the measured reference height when
the trailer is attached. If the rear bumper is
higher than the measured reference height
when loaded, the vehicle may handle unpre-
dictably which could cause a loss of vehicle
control and cause serious personal injury or
property damage.
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 sup-
plier 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 lbs.
(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 lbs.
(1,587 kg).
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, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer’s
specifications.
