TOWING A TRAILER

Do not tow a trailer with your vehicle.

FLAT TOWING

UNIFORM TIRE QUALITY GRADING

Towing your vehicle with all four wheels on the

ground is sometimes called flat towing. This

method is typically used when towing a vehicle

behind a recreational vehicle, such as a motor

home.

DOT (Department Of Transportation) Quality

Grades: All passenger car tires must conform to

federal safety requirements in addition to these

grades.

Quality grades can be found where applicable on

the tire sidewall between tread shoulder and

maximum section width. For example:

CAUTION

•

Failure to follow these guidelines can

result in severe reduction gear dam-

age.

Treadwear 200 Traction AA Temperature A

TREADWEAR

•

DO NOT tow this vehicle with all four

wheels on the ground (flat towing).

For emergency towing procedures re-

fer to “Towing your vehicle” in the “In

case of emergency” section of this

manual.

The treadwear grade is a comparative rating

based on the wear rate of the tire when tested

under controlled conditions on a specified gov-

ernment 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 however, 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 lowest, are

AA, A, B and C. Those grades represent the tire’s

ability to stop on wet pavement as measured

9-14 Technical and consumer information

REPORTING SAFETY DEFECTS

For USA

under controlled conditions on specified govern-

ment test surfaces of asphalt and concrete. A tire

marked C may have poor traction performance.

WARNING

If you believe that your vehicle has a de-

fect which could cause a crash or could

cause injury or death, you should immedi-

ately inform the National Highway Traffic

Safety Administration (NHTSA) in addi-

tion to notifying NISSAN.

The temperature grade for this tire is es-

tablished for a tire that is properly in-

flated and not overloaded. Excessive

speed, under-inflation, or excessive load-

ing, either separately or in combination,

can cause heat build-up and possible tire

failure.

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.

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. However, NHTSA cannot be-

come involved in individual problems be-

tween you, your dealer, or NISSAN.

TEMPERATURE A, B AND C

The temperature grades A (the highest), B, and

C, representing the tire’s resistance to the gen-

eration of heat and its ability to dissipate heat

when tested under controlled 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 exces-

sive temperature can lead to sudden tire failure.

The grade C corresponds to a level of perfor-

mance 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.

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;

write

to:

Administrator, NHTSA, 400 Seventh Street,

SW., Washington, D.C. 20590. You can

vehicle safety from http://www.safercar.gov.
