CAUTION
Always keep the engine running while
operating the soft top. The top will also
operate when the ignition switch is in
the ONposition, but run the engine to
prevent a discharged battery.
Be sure to follow the operating instructions, and
all the warnings and cautions in this section.
Improper operation of the top could cause
a system malfunction, damage, or deterio-
ration of the top material and related parts.
WARNING

Park the vehicle in a safe and level
place and apply the parking brake.

Make sure the area is clear of ob-
stacles and there is enough clear-
ance over the top (for example, in a
garage or a covered area). More than
approximately 6.6 ft (2 m) from the
ground is required to open or close
the top safely. Otherwise, the top
may damage any objects above itwhile moving. The top operating sys-
tem could also be damaged.

Do not operate the top in a strong
wind. It could be blown by the wind,
striking someone or damage the top.

Do not allow anyone to stand up or
extend any portion of their body out
of the opening while the vehicle is in
motion or while the top is being op-
erated.

In an accident you could be thrown
from the vehicle with an open top.
Always use seat belts and proper
child restraints.
CAUTION

Do not operate the top when the
temperature is below 32°F (0°C). This
may result in damage to the top ma-
terial or operating system.

Remove water drops, snow, ice or
sand from the top, and dry the sur-face of the top completely before
opening it.

Do not open the top when it is wet or
damp. This may cause interior water
damage, stains or mildew on the top
material.

Be sure to turn off the rear window
defroster switch. Never turn it on
while the top is being operated or
fully opened. The heat may damage
the top material.

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
•The vehicle is raised for service.
•You suspect that exhaust fumes
are entering into the passenger
compartment.
•You notice a change in the sound
of the exhaust system.
•You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.THREE WAY CATALYSTThe three way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-mals or flammable materials away
from the exhaust system compo-
nents.

Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION

Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst’s ability
to help reduce exhaust pollutants.

Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.

Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system displays
pressure of all tires (except the spare tire) on the
trip computer by sending a signal from a sensor
that is installed in each wheel.
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the
tire which can cause a lower tire inflation pres-
sure. This may cause the low tire pressure
warning light to illuminate.
If the warning light illuminates in low ambient
temperatures as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown

Make sure the area around the vehicle is
clear.

Maintenance items should be checked peri-
odically, for example, each time you check
engine oil.

Check that all windows and lights are clean.

Visually inspect tires for their appearance and
condition. Also check tires for proper infla-
tion.

Lock all doors.

Position seat and adjust head restraints.

Adjust inside and outside mirrors.

Fasten seat belts and ask all passengers to
do likewise.

Check the operation of warning lights when
key is turned to the ON (3) position. See
“Warning/indicator lights and audible re-
minders” in the “2. Instruments and controls”
section.1. Apply the parking brake.
2.Automatic transmission:
Move the selector lever to P (Park) or N
(Neutral). (P preferred.)
The starter is designed not to operate if the
selector lever is in one of the driving posi-
tions.
Manual transmission:
Move the shift lever to N (Neutral) position,
and depress the clutch pedal to the floor
while cranking the engine.
The starter is designed not to operate unless
the clutch pedal is fully depressed.
3. Crank the enginewith your foot off the
accelerator pedalby turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails to
run, repeat the above procedure.

If the engine is very hard to start in extremely
cold weather or when restarting, depress the
accelerator pedal a little (approximately 1/3
to the floor) and hold it then crank the engine.
Release the key and the accelerator pedal
when the engine starts.

If the engine is very hard to start because it is
flooded, depress the accelerator pedal all theway to the floor and hold it. Crank the engine
for 5 to 6 seconds. After cranking the engine,
release the accelerator pedal. Crank the en-
ginewith your foot off the accelerator
pedalby turning the ignition key to START.
Release the key when the engine starts. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, other-
wise the starter could be damaged.
4.Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the en-
gine while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather.
In cold weather, keep the engine running for
a minimum of 2 to 3 minutes before shutting
it off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.

shift mode. Shift range can be selected manu-
ally.
In the manual shift mode, the shift range is
displayed on the position indicator in the meter.
Shift ranges up or down one by one as follows:M1→
←
M2→
←
M3→
←
M4→
←
M5
M5 (5th):
Use this position for all normal forward driving.M4 (4th):
For driving up or down long slopes where engine
braking would be advantageous.M3 (3rd) and
M2 (2nd):
Use for hill climbing or engine braking on down-
hill grades.
M1 (1st):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
sand or mud, or for maximum engine braking on
steep downhill grades.

Remember not to drive at high speeds for
extended periods of time in lower than
M4
range. This reduces fuel economy.

When shifting up, move the selector lever to
the + (up) side. (Shifts to higher range.)
When shifting down, move the selector lever
to the − (down) side. (Shifts to lower range.)

Moving the selector lever to the same side
twice will shift the ranges in succession.
However, if this motion is rapidly done, the
second shifting may not be completed prop-
erly.

In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop.
When accelerating again, it is necessary
to shift up to the desired range.

When canceling the manual shift mode, re-
turn the selector lever to the D position. The
transmission returns to the normal driving
mode.

In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age or loss of control.
Accelerator downshift
— In D position —For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear, depend-
ing on the vehicle speed.
Fail-safeWhen the fail-safe operation occurs, the next
time the key is turned to the ON position, the
warning light will blink for approximately 8
seconds after coming on for 2 seconds. While
the vehicle can be driven under these circum-
stances please note that the gears in the auto-
matic transmission will be locked in 4th gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition key
OFF and wait for 3 seconds. Then turn the
key back to the ONposition. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition, have your NISSAN
dealer check the transmission and repair if
necessary.
