Air Flow ControlINFOID:0000000009463196
DESCRIPTION
• Front air control changes duty ratio of front blower mo tor control signal to control air flow continuously. When
air flow is increased, duty ratio of front blower mo tor control signal gradually increases to prevent a sudden
increase in air flow.
• In addition to manual control, air flow control is composed of fan speed control at door motor operation.
FAN SPEED CONTROL AT DOOR MOTOR OPERATION
When mode door motor is activated while air flow is more than the specified value, front air control temporarily
reduces fan speed so that mode door moves smoothly.
Air Inlet ControlINFOID:0000000009463197
The intake door position is automatically controlled in MAX A/C and DEF modes. The intake door is controlled
by customer input in the other modes.
Air Outlet ControlINFOID:0000000009463198
Air outlet control is controlled by customer input. When t he A/C is turned off by turning the blower control dial
fully counterclockwise, the front air control retains the current selections and returns to these selections the
next time the blower control dial is turned to any fan position.
NOTE:
If ambient temperature is excessively low, D/F is se lected to prevent windshield fogging when air outlet is set
to FOOT.
Compressor ControlINFOID:0000000009463199
DESCRIPTION
In order for the IPDM E/R to complete a compress or ON request, the following conditions must be met:
1. The BCM detects a Fan ON signal from the front air control. The front air control grounds the fan ON sig-
nal monitored by the BCM when the blower speed dial is in any of the fan speed positions.
2. The BCM detects an A/C ON signal from the front air control. The front air control grounds the A/C ON sig-
nal monitored by the BCM when:
- The A/C switch is pressed. The A/C switch LED ill uminates and the front air control grounds the A/C ON
signal monitored by the BCM. Any mode c ontrol button except D/F may be selected.
- The A/C switch is OFF, and the MAX A/C button is pr essed. The A/C switch LED will automatically illumi-
nate and the front air control grounds the A/C ON signal monitored by the BCM.
- The A/C switch is OFF, and the mode button for either D/F or DEF is selected. The front air control
grounds the A/C ON signal monitored by the BCM, but it does not illuminate the A/C switch LED
NOTE:
If the compressor was engaged by pressing the D/F or DE F mode buttons, and the time spent in either mode
exceeds 1 minute, then the compressor stays reques ted, even when modes other than D/F or DEF are
selected, until either:
1. The ignition switch is turned OFF.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the pos ition the seat is in and the load placed on the seat when
the noise is present. These conditions should be dupl icated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of thes e incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component installed to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator installation pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine rpm or
load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

General maintenance includes those items which shoul d 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 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.
Item Reference page
Tires Check the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear. MA-39
Wheel nuts
When checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary. MA-39
Tire rotation
Tires should be rotated every 5,000 miles (8,000 km). MA-39

nents Replace the TPMS transmitter grommet seal, valve core and cap when the tires
are replaced due to wear or age. WT-57
Wheel alignment and
balance If the vehicle should pull to either side while driving on a straight and level road,
or if you detect uneven or abnormal tire wear, there may be a need for wheel
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed. For additional information regarding tires, refer
to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada)
in the NISSAN Warranty Information Booklet. FSU-25
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. —
Windshield wiper
blades Check for cracks or wear if they do not wipe properly. —
Doors and engine
hood Check that all doors and the engine hood operate properly. Also make sure that
all latches lock securely. Lubricate if necessary. Make sure that the secondary
latch keeps the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lu-
brication frequently. MA-45, "LOCKS, HING-
ES AND HOOD LATCH :

Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and oth-
er lamps are all operating properly and installed securely. Also check headlamp
aim. Clean the headlamps on a regular basis. EXL-122

Warning lamps and
chimes Make sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washer Check that the wipers and washer operate properly and that the wipers do not
streak. —
Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner. —
Steering wheel Check that it has the specified play. Check for changes in the steering condition,
such as excessive play, hard steering or strange noises.
