TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling and performance may be adversely af-
fected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 5,000 miles (8,000 km).
(See
“Flat tire” (P.6-3) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque:80 ft-lb (108 N·m)

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.9-17).)
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 axleto 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.Do not tow a trailer with your
vehicle.
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).
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.

For Canada
If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform Transport
Canada in addition to notifying
INFINITI.
If Transport Canada receives com-
plaints, it may open an investigation,
and if it finds that a safety defect
exists in a group of vehicles, it may
request that INFINITI conduct a recall
campaign. However, Transport Cana-
da cannot become involved in indivi-
dual problems between you, your
retailer, or INFINITI.

361-4792.WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dynam-
ometers used by some states for emissions
testing), or similar equipment. Make sure
you inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the wrong
test equipment may result in transmission
damage or unexpected vehicle movement
which could result in serious vehicle da-
mage or personal injury.
Due to legal requirements in some states/
areas or provinces, your vehicle may be
required to be in what is called the
“ready
condition” for an Inspection/Maintenance
(I/M) test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
the vehicle may be reset to a “not ready
