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.
. For emergency towing procedures refer
to“Towing recommended by INFINITI”
(P.6-18) of this manual.
Automatic transmission
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.
Manual transmission
. Always tow with the manual transmis-
sion in Neutral.
. Your vehicle speed should never exceed
70 MPH (112 km/h) when flat towing
your vehicle.
. After towing 500 miles, start and idle
the engine with the transmission in
Neutral for two minutes. Failure to idle
the engine after every 500 miles of
towing may cause damage to the
transmission’s internal parts.
TOWING A TRAILER
Page 452 of 466

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course. For
example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to suddentire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading,
either separately or in combination, can
cause heat build-up and possible tire failure.

If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform the Na-
tional Highway Traffic Safety Admin-
istration (NHTSA) in addition to
notifying INFINITI.
If NHTSA receives similar complaints,
it may open an investigation, and if it
finds that a safety defect exists in a
group of vehicles, it may order a
recall and remedy campaign. How-
ever, NHTSA cannot become involved
in individual problems between you,
your retailer, or INFINITI.
To contact NHTSA, you may call the
Vehicle Safety Hotline toll-free at 1-
888- 327-4236 (TTY: 1-800-424-
9153); go to http://www.safercar.
gov; or write to: Administrator,

You may notify INFINITI by contacting
our Consumer Affairs Department,
toll-free, at 1-800-662-6200.
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.
You may contact Transport Canada’s
Defect Investigations and Recalls
Division toll free at 1-800-333-0510.

Additional information concerning
motor vehicle safety may be obtained

safety (English speakers) or www.tc.
gc.ca/securiteroutiere (French speak-
ers).
To notify INFINITI of any safety con-
cerns please contact our Consumer
Information Centre toll free at 1-800-
361-4792.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
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.
