If you plan to travel in another country,
you should first find out if the fuel
available is suitable for your vehicle

’s

engine.

Using fuel with too low an octane rating
may cause engine damage. All gasoline
vehicles must be operated with unleaded
gasoline. Therefore, avoid taking your
vehicle to areas where appropriate fuel is
not available.

When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify
the vehicle to meet local laws and regula-
tions.

The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications
may differ.

When any vehicle is to be taken into
another country, state, province or district
and registered, its modifications, trans-
portation, and registration are the respon-
sibility of the user. INFINITI is not
responsible for any inconvenience that
may result.

WARNING

.

It is extremely dangerous to ride
in a cargo area inside the vehicle.
In a collision, people riding in
these areas are more likely to be
seriously injured or killed.

.

Do not allow people to ride in any
area of 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
loading your vehicle:

.

Curb Weight (actual weight of your

vehicle) - vehicle weight includ-
ing: standard and optional equip-
ment, 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 informa-
tion is located on the F.M.V.S.S./
C.M.V.S.S. label.

.

GAWR (Gross Axle Weight Rating) -

maximum weight (load) limit spe-
cified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. 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 - max-
imum total weight limit specified

VEHICLE LOADING INFORMATION

of the load (passengers and car-
go) for the vehicle. 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
included 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 weight of
total occupants weight subtracted
from the load limit.

STI0365

VEHICLE LOAD CAPACITY

Do not exceed the load limit of your
vehicle 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 Capa-

city

” on the Tire and Loading In-

formation label.

To get

“the combined weight of

occupants and cargo

”, add the

weight of all occupants, then add

the total luggage weight. Examples
are shown in the illustration.

Steps for determining correct load
limit

1.

Locate the statement

“The com-

bined 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.

Technical and consumer information

9-21

9-22

Technical and consumer information

3.

Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.

4.

The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehi-
cle, 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 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,
confirm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. (See

“Mea-

surement of weights

” (P.9-23).)

Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.

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 label.

.

Do not load the front and rear axle

to the GAWR. Doing so will exceed
the GVWR.

WARNING

.

Properly secure all cargo to help
prevent it from sliding or shifting.
Do not place cargo higher than the

seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal 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 result in loss
of control and cause personal
injury.

.

Overloading could not only short-
en the life of your vehicle and the
tires, but also could lead to
hazardous vehicle handling and
long braking distance. This may
cause a premature tire malfunc-
tion, which could result in a
serious accident and personal in-
jury. Failures caused by overload-
ing 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 sepa-
rately to determine axle loads. In-
dividual 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 ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings.

Your vehicle was designed to be used to
carry passengers and cargo. INFINITI does
not recommend trailer towing, because it
places additional loads on your vehicle

’s

engine, drivetrain, steering, braking, 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 capability and
the special equipment required for proper
towing.

CAUTION

Vehicle damage resulting from towing a
trailer is not covered by INFINITI warranties.

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.

. 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.6-12) of this manual.

All-Wheel Drive (AWD) models:

Do not tow an AWD vehicle with any of the
wheels on the ground.
