ROOF MOUNTED ANTENNA
The antenna is located on the rear part of
the vehicle roof.
CAUTION
• A build up of ice on the antenna can
affect radio performance. Remove
the ice to restore radio reception.
• When removing snow from the roof,
do not apply strong force to the an-
tenna. That might break the antenna
and dent the roof panel.
• When using a high pressure car wash,
keep the high pressure nozzle away
from the antenna. The seal may be
deformed or damaged.
• The radio performance may be af-
fected if cargo carried on the roof
blocks the radio signal. If possible, do
not put cargo near the antenna. When installing a CB, ham radio or car
phone in your vehicle, be sure to observe
the following precautions; otherwise, the
new equipment may adversely affect the
engine control system and other electronic
parts.
WARNING
• A cellular phone should not be used
for any purpose while driving so full
attention may be given to vehicle op-
eration. Some jurisdictions prohibit
the use of cellular phones while
driving.
• If you must make a call while your
vehicle is in motion, the hands free
cellular phone operational mode is
highly recommended. Exercise ex-
treme caution at all times so full at-
tention may be given to vehicle
operation.
• If you are unable to devote full atten-
tion to vehicle operation while talk-
ing on the phone, pull off the road to
a safe location and stop your vehicle.
CAUTION
• Keep the antenna as far away as pos-
sible from the electronic control
modules.
• Keep the antenna wire more than 8 in
(20 cm) away from the electronic
control system harnesses. Do not
route the antenna wire next to any
harness.
• Adjust the antenna standing-wave
ratio as recommended by the
manufacturer.
• Connect the ground wire from the CB
radio chassis to the body.
• For additional information, it is rec-
ommended that you visit a NISSAN
dealer for servicing.

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 appli-
cable 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 rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, 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 low-
est, are AA, A, B, and C. Those grades repre-
sent the tire's ability to stop on wet pave-
ment as measured under controlledconditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include ac-
celeration, cornering, hydroplaning, or
peak traction characteristics.
Temperature A, B and C
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat, and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the mini-
mum 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 combi-
nation, can cause heat build-up and
possible tire failure.
