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 transmis-

sion 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 NISSAN”

in the “In case of emergency” section of

this manual.

Automatic Transmission

To tow a vehicle equipped with an automatic

transmission, an appropriate vehicle dolly MUST

be placed under the towed vehicle’s drive

wheels. Always follow the dolly manufacturer’s

recommendations when using their product.

WARNING

Do not use this vehicle for snowplowing.

Installing a snowplow may affect vehicle

handling. This may cause the driver to lose

control of the vehicle and could result in

serious vehicle damage or personal injury.

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:
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 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 the 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 mea-

sured under controlled conditions on specified

government test surfaces of asphalt and con-

crete. A tire marked C may have poor traction

performance.
