A/T CONTROL SYSTEM
The line pressure is temporarily reduced corresponding to a change
in engine torque when shifting gears (that is, when the shift solenoid
valve is switched for clutch operation) to reduce shifting shock.
AT LOW FLUID TEMPERATURE
• A/T fluid viscosity and frictional characteristics of the clutch facing change with A/T fluid temperature. Clutch
engaging or band-contacting pressure is compensated for, according to A/T fluid temperature, to stabilize
shifting quality.
• The line pressure is reduced below 60°C (140°F) to prevent shift-
ing shock due to high viscosity of A/T fluid when temperature is
low.
• Line pressure is increased to a maximum irrespective of the throt-
tle opening when A/T fluid temperature drops to −10°C (14°F). This
pressure rise is adopted to prevent a delay in clutch and brake
operation due to extreme drop of A/T fluid viscosity at low temper-
ature.
Shift ControlINFOID:0000000001703167
The shift is regulated entirely by electronic control to accommodate vehicle speed and varying engine opera-
tions. This is accomplished by electrical signals transmitted by the revolution sensor and the ECM (accelerator
pedal position sensor). This results in improved acceleration performance and fuel economy.
CONTROL OF SHIFT SOLENOID VALVES A AND B
The TCM activates shift solenoid valves A and B according to sig-
nals from the accelerator pedal position sensor and revolution sen-
sor to select the optimum gear position on the basis of the shift
schedule memorized in the TCM.
The shift solenoid valve performs simple ON-OFF operation. When
set to “ON”, the drain circuit closes and pilot pressure is applied to
the shift valve.

DTC P0101 MAF SENSOR
Component DescriptionINFOID:0000000001702648
The mass air flow sensor (1) is placed in the stream of intake air. It
measures the intake flow rate by measuring a part of the entire
intake flow. The mass air flow sensor controls the temperature of the
hot wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.

Explanation of General MaintenanceINFOID:0000000001704720
General MaintenanceINFOID:0000000001704721
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or they can have their NISSAN dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.

PERIODIC MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary. L = Lubricate.
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil (exc. LSD) at
every 30,000 miles (48,000 km) or 24 months, and change LSD gear oil every 15,000 miles (24,000 km) or 12 months.
(2) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with CON-
SULT-II every 60,000 miles (96,000 km), then change CVT fluid NS-2 if necessary. If CONSULT-II is not available, change (not just
inspect) CVT fluid NS-2 every 60,000 miles (96,000 km). Using transmission fluid other than Genuine NISSAN CVT Fluid NS-2 will
damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
(3) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.

Checking Drive BeltsINFOID:0000000001704729
WARNING:
Be sure to perform this step when the engine is stopped.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B) in the fig-
ure.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000001704730
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Changing Engine CoolantINFOID:0000000001704731
WARNING:
• To avoid being scalded, do not change engine coolant when engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a
turn to release built-up pressure. Then turn the cap all the way.
• Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
• Vehicle front
When drain all of engine coolant in the system, open water
drain plug on cylinder block. Refer to EM-76
.
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
