AIR CONDITIONER SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioner system in this NIS-
SAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system lubricant
Type R or the exact equivalents.
CAUTION
Use of any other refrigerant or lubricant
will cause severe damage and you will
need to replace your vehicle's entire air
conditioner system.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth's
ozone layer. Although this refrigerant does
not affect the earth's atmosphere, certain
government regulations require the recov-
ery and recycling of any refrigerant during
automotive air conditioner system service.
An authorized NISSAN dealer has the
trained technicians and equipment needed
to recover and recycle your air conditioner
system refrigerant.
Contact an authorized NISSAN dealer when
servicing your air conditioner system.

prevent load shift while driving.
IBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
IAlways secure items in the trailer to
prevent load shift while driving.
I
Avoid abrupt starts, acceleration or
stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,first block the wheels and apply the
parking brake, and then move the trans-
mission shift selector lever into the P
(Park) position. If you move the shift
lever to the P (Park) position before
blocking the wheels and applying the
parking brake, transmission damage
could occur.
IWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
IIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
ITrailer towing requires more fuel than
normal circumstances.
IAvoid towing a trailer for your vehicle'sfirst 500 miles (805 km).
IHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
IWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
ICrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
IBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.

ITo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
IAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change oil in the
transmission more frequently. For addi-
tional information see the ``Maintenance''
section earlier in this manual.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However, rela-
tive tire performance depends on actual
driving conditions, and may vary signifi-
cantly 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 repre-
sent the tire's ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
