TIRE CHAINSY51D-V-E01-47993005-C05E-49C6-A4F7-595D3F032FD5Use 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.

Tire rotationY51D-V-E01-F7870CCD-932B-47A8-8F27-7722EA305689
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.

9-18Technical and consumer information
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.9-18).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPSY51D-V-E01-367C9547-B8F4-40A5-BCE4-39C37DBD2B67.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 WEIGHTSY51D-V-E01-626A0DEF-CEAF-4B2B-B914-1CD2D9E7382E
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.

Y51D-V-E01-1566689B-E555-4824-98F9-8466E02C8EE3A vehicle equipped with Intelligent All-
Wheel Drive (AWD) should never be tested
using a two wheel dynamometer (such as
the dynamometers used by some states for
emissions testing), or similar equipment.
Make sure you inform test facility person-
nel 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 damage or personal injury.
Due to legal requirements in some states/
areas, 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
condition”. Before taking the I/M test,
check the vehicle’s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is
“not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing.
