•Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect ve-
hicle performance and vehicle emissions.
Not all fuel dispensers are labeled to in-
dicate MMT content, so you may have to
consult your gasoline retailer for more
details. Note that Federal and California
laws prohibit the use of MMT in refor-
mulated gasoline.
• U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers de-
veloped this specification to improve emis-
sion control system and vehicle performance.
Ask your service station manager if the gaso-
line meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated
gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates 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 recom-
mended for unleaded gasoline.
• If an oxygenate-blend other than metha-
nol blend is used, it should contain no more
than 15% oxygenate. •
If a methanol blend is used, it should con-
tain no more than 5% methanol (methyl
alcohol, wood alcohol). It should also con-
tain a suitable amount of appropriate co-
solvents and corrosion inhibitors. If not
properly formulated with appropriate co-
solvents and corrosion inhibitors, such
methanol blends may cause fuel system
damage and/or vehicle performance prob-
lems. 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
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a non-oxygenate fuel or
a fuel with a low blend of MTBE.
Take care not to spill gasoline during refuel-
ing. Gasoline containing oxygenates can
cause paint damage.
E–15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline.
E-15 can only be used in vehicles designed to
run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing pumps
to be identified with small, square, orange
10-4Technical and consumer information

CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the INFINITI New Vehicle Limited
Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter change
intervals depend upon how you use your
vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at cold out- side temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting
For additional information on maintenance
schedules, see “Maintenance and schedules”
(P. 9-2).AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and the oil, Genu-
ine NISSAN A/C System Oil Type ND-OIL12
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 HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive 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 including:
standard and optional equipment,
fluids, emergency tools, and spare
tire assembly. This weight does not
include 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. •
GAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified
for the front or rear axle. This infor-
mation 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.
• Cargo capacity - permissible weight of cargo, the subtracted weight of
occupants from the load limit.
VEHICLE LOADING INFORMATION
Technical and consumer information10-15

cargo should never exceed XXX lbs.
or XXX kg” 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 lbs. or XXX kg.
4. The resulting figure equals the available amount of cargo and lug-
gage load capacity. For example, if
the XXX amount equals 1,400 lbs.
and there will be five 150 lbs. pas-
sengers in your vehicle, 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 calcu-
lated 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, see “Measure-
ment of weights” (P. 10-18).
Also check tires for proper inflation
pressures. For additional information,
see “Tire and Loading Information la-
bel” (P. 8-28).
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 load
for 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.
NOTE:
Tow hitches are available as an accessory for
this vehicle. If a tow hitch is installed, the
liftgate electronic control unit (ECU) needs
to be replaced with an ECU programmed
with towing logic for the Motion-Activated
Liftgate to function properly.
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
Technical and consumer information10-19

CAUTION
If your vehicle is equipped with the Life-
style Receiver to avoid damage to your ve-
hicle 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, see “If your vehicle overheats”
(P. 6-7)
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 be-
comes 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 nor-
mally 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.
