However, for long steep grades, do not stay in
1st or 2nd gear when driving above 35 MPH (56
km/h).

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
trol to the HOT position.

Trailer towing requires more fuel than normal
circumstances.

Avoid towing a trailer for the first 500 miles
(800 km).

Have your vehicle serviced more often than at
intervals specified in the recommended Main-
tenance Schedule.
When towing a trailer, change oil in the
transmission more frequently. See the
Maintenance Schedule.UNIFORM TIRE QUALITY GRADINGDOT (Department of Transportation) Quality
Grades: All passenger car tire 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 andmaximum section width. For example:
Treadwear 200 Traction AA Temperature A
TreadwearTreadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government 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. How-
ever, relative tire performance depends on actual
driving conditions, and may vary significantly due
to variations in driving habits, service practices
and differences in road characteristics and cli-
mate.Traction AA, A, B and CThe 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.
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 CTemperature 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 conditions on a speci-
fied indoor laboratory test wheel. Sustained high
temperature can cause tire material to degener-
ate, reducing tire life. Excessive temperatures
can lead to sudden tire failure. Grade C corre-
sponds to a performance level which all passen-
ger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A and
B represent higher levels of performance on
laboratory test wheels than the minimum re-
quired by law.Technical and consumer information

In Hawaii call (808) 836-0888.
Due to legal requirements in some states/
areas, your vehicle may be required to be in what
is called the ready condition for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the ready condition when it
is driven through certain driving patterns. Usu-
ally, 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, drive the vehicle through the following
pattern to set the vehicle to the ready condition.
If you cannot or do not want to perform the
driving pattern, a NISSAN dealer can conduct it
for you.
WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic
conditions, and obey all traffic laws.
1. Start the engine. Allow the engine to idle until
the engine coolant temperature gauge needle
points between the C and H (normal operat-
ing temperature).2. Accelerate the vehicle to 55 MPH (88 km/h),
then quickly release the accelerator pedal
completely and keep it released for at least 6
seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed of
53 to 60 MPH (86 to 96 km/h) for at least 5
minutes.
4. Stop the vehicle. Leave the engine running.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 and 5 at least 3 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 minutes.
8. Stop the vehicle. Place the transmission gear
shift lever in the “P” or “N” position.
9. Turn the engine off.
10.Repeat steps 1 through 8 at least one more
time.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is ac-
ceptable between steps. Do not stop the engine
until step 7 is completed.READINESS FOR INSPECTION/
