FUEL RECOMMENDATION
INFINITI recommends the use of premium un-
leaded gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96) . If unleaded premium gaso-
line is not available, you may use unleaded regular
gasoline with an octane rating of at least 87 AKI
number (Research octane number 91) , but you
may notice a decrease in performance.
CAUTION
●Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
● Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel can damage
the fuel system components and is not
covered by the INFINITI vehicle limited
warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. INFINITI
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates such as ethanol, MTBE and methanol with
or without advertising their presence. INFINITI
does not recommend the use of fuels of which the
oxygenate content and the fuel compatibility for
your INFINITI cannot be readily determined. If in
doubt, ask your service station manager.
If you use oxygenate-blend gasoline, please take
the following precautions as the usage of such
fuels may cause vehicle performance problems
and/or fuel system damage. ●
The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
●
If an oxygenate-blend other than metha-
nol blend is used, it should contain no
more than 10% oxygenate. (MTBE may,
however, be added up to 15%.)
●If a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol) . It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are
suitable for use in INFINITI vehicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.

AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the oil, NISSAN
A/C system oil DH-PS or the exact equiva-
lents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replace-
ment 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 regula-
tions require the recovery and recycling of any
refrigerant during automotive air conditioner sys-
tem service. An INFINITI dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.
Contact an INFINITI dealer when servicing your
air conditioner system.

TERMS
It is important to familiarize yourself with
the following terms before loading your
vehicle:
● Curb Weight (actual weight of your
vehicle) - vehicle weight including:
standard and optional equipment, flu-
ids, emergency tools, and spare tire
assembly. This weight does notin-
clude passengers 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, pas-
sengers, luggage, hitch, trailer
tongue load and any other optional
equipment. This information is lo-
cated on the F.M.V.S.S./C.M.V.S.S.
certification label.

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.
certification label.
● GCWR (Gross Combined Weight
rating) - The maximum total weight
rating of the vehicle, passengers,
cargo, and trailer.
● Vehicle Capacity Weight, Load limit,
Total load capacity - maximum total
weight limit specified of the load
(passengers and cargo) for the ve-
hicle. This is the maximum combined weight of occupants and cargo that
can be loaded into the vehicle. If the
vehicle 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 label (if so
equipped) .
● Cargo capacity - permissible weight
of cargo, the subtracted weight of
occupants from the load limit.
VEHICLE LOAD CAPACITY
Do not exceed the load limit of your ve-
hicle shown as “The combined weight of
occupants and cargo” on the Tire and
Loading Information label. Do not exceed
the number of occupants shown as
“Seating Capacity” on the Tire and Load-
ing Information label.

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 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 55
lbs. (245 N) to a single
Aplastic hook or 44
lbs. (196 N) to a single
Bplastic hook
when securing cargo.
Do not apply a total load of more than 110
lbs. (490 N) to a single metal 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.
● The child restraint top tether strap may
be damaged by contact with items in

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 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 vehicle wear in at the
heavier loads.
Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at www.InfinitiUSA.com. This
guide includes information on trailer towing ca-
pability 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 following Towing
Load/Specification Chart found later in this sec-
tion. The total trailer load equals trailer weight
plus its cargo weight.
● When towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight Rating
(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 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 appro-
priate for level highway driving may have to be
reduced for low traction situations (for example,
on slippery boat ramps) .

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outside
temperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally 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 col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing 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 overheats” in the “In case of emer-
gency” 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 distrib-
uting hitch, keep the tongue load between 10 -
15 percent of the total trailer load or use the
trailer tongue load specified by the trailer manu-
facturer. The tongue load must be within the
maximum tongue load limits shown in the follow-
ing “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

Towing capacities are calculated assuming a
base vehicle with driver and any options required
to achieve the rating. Additional passengers,
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 measured
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 proce-
dure.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 avail-
able maximum tongue/king pin load. To determine the available towing capacity, use
the following procedure.
1. Find the GCWR for your vehicle on the \bTowing Load/Specification\b chart found
later in this section.
2. Subtract the actual vehicle weight from the GCWR. The remaining amount is the avail-
able 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 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 - 6,400 lb. (2902 kg) . ●

The available towing capacity may be less than
the maximum towing capacity due to the passen-
ger 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 recommended
by the trailer manufacturer. If the tongue load
becomes excessive, rearrange the cargo to ob-
tain the proper tongue load. Do not exceed the
maximum tongue weight specification shown in
the “Towing load/specification” chart 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.
