equipped)
1. Automatic Transmission fluid tempera-ture gauge
2. Voltmeter
3. Engine oil pressure gauge
4. Engine oil temperature gauge
Automatic Transmission fluid
temperature gauge
This gauge indicates the temperature of
the automatic transmission fluid.
CAUTION
• This gauge is not designed to indi-
cate low automatic transmission
fluid level. Use the dipstick to check
the fluid level. For additional infor-
mation, see “Automatic Transmis-
sion Fluid (ATF)” (P. 8-13).

transmission fluid temperature over
the normal range, stop the vehicle as
soon as safely possible. It is recom-
mended that you have the vehicle
checked by a NISSAN dealer. Contin-
ued operation of the vehicle may se-
riously damage the transmission.
Voltmeter
When the ignition switch is placed in the ON
position, the voltmeter indicates the bat-
tery voltage. When the engine is running, it
indicates the generator voltage.
While cranking the engine, the volts drop
below the normal range. If the range is not
within the normal range (11 – 15 volts) while
the engine is running, it may indicate that
the charging system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Engine oil pressure gauge
The gauge indicates the engine lubrication
system oil pressure while the engine is run-
ning. The bar should be in the middle of the
gauge when the engine is running.
CAUTION
• This gauge is not designed to indi-
cate low engine oil level. Use the dip-
stick to check the oil level. For addi-
tional information, see “Engine oil”
(P. 8-8).
• If the gauge needle does not move
with the proper amount of engine oil,
it is recommended that you have the
vehicle checked by a NISSAN dealer.
Continued vehicle operation in such
a condition could cause serious dam-
age to the engine.
Engine oil temperature gauge
This gauge measures the temperature of
the engine oil.

Maintenance
The maintenance menu allows the user to set reminders for various vehicle maintenance items.
Some menu items shown below may not be equipped on your vehicle.
WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, see “Changing wheels and tires” (P. 8-41). Many factors including tire inflation, alignment, driving habits and road conditions
affect tire wear and when tires should be replaced. Setting the tire replacement indicator for a certain driving distance does not
mean your tires will last that long. Use the tire replacement indicator as a guide only and always perform regular tire checks.
Failure to perform regular tire checks, including tire pressure checks could result in tire failure. Serious vehicle damage could
occur and may lead to a collision, which could result in serious personal injury or death.

spected soon. It is recommended that you
visit a NISSAN dealer for this service. For
additional information, see “Malfunction In-
dicator Light (MIL)” (P. 2-19).
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-13).

AUTOMATIC TRANSMISSION (A/T)
WARNING
• Do not depress the accelerator pedal
while shif ting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive). Always
depress the brake pedal until shif ting
is completed. Failure to do so could
cause you to lose control and have an
accident.
• Cold engine idle speed is high, so use
caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
• Never shif t to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
reversing. This could cause an acci-
dent or damage the transmission. •
Do not downshif t abruptly on slip-
pery roads. This may cause a loss of
control.
• Except in an emergency, do not shif t
to the N (Neutral) position while driv-
ing. Coasting with the transmission
in the N (Neutral) position may cause
serious damage to the transmission.CAUTION
• To avoid possible damage to your ve-
hicle, when stopping the vehicle on
an uphill grade, do not hold the ve-
hicle by depressing the accelerator
pedal. The foot brake should be used
for this purpose.
The A/T in your vehicle is electronically con-
trolled to produce maximum power and
smooth operation.
The recommended operating procedures
for this transmission are shown on the fol-
lowing pages. Follow these procedures for
maximum vehicle performance and driv-
ing enjoyment.
Starting and driving5-19

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• For vehicles equipped with
, use 4H
or 4L position only when necessary.
4-Wheel Drive operation lowers fuel
economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine
oil and oil filter recommendations”
(P. 10-7).
WARNING
• For 4WD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.
• Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing), or similar equipment
even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with 4WD
before it is placed on a dynamom-
eter. Using the wrong test equipment
may result in drivetrain damage or
unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.CAUTION
• Do not drive the vehicle in the 4H or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in
4H or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD vehicle information dis-
play warning message turns on
when you are driving on dry hard sur-
face roads:
– In the 4H position, shif t the 4WD
shif t switch to 2WD.
– In the 4LO position, stop the ve-
hicle, move the shif t lever to the N
(Neutral) position with the brake
pedal depressed, and shif t the
4WD shif t switch to 2WD.
• If the vehicle information display
warning message is still on af ter the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended that you visit a NISSAN
dealer for this service.

tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
