OK >> Check fuel level sensor unit installation, and check whether the float arm interferes or binds with
any of the internal components in the fuel tank. Repair or replace malfunctioning part, if neces-
sary.

Fuel Gauge Fluctuates, Indicates Wrong Value, or VariesINFOID:0000000001704505
1.CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Move to Full-positionINFOID:0000000001704506
1.OBSERVE FUEL GAUGE
Does it take a long time for the pointer to move to FULL position?
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2.IDENTIFY FUELING CONDITION
Was the vehicle fueled with the ignition switch ON?
YES or NO
YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO >> GO TO 3.
3.OBSERVE VEHICLE POSITION
Is the vehicle parked on an incline?
YES or NO
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4.OBSERVE FUEL GAUGE POINTER
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES or NO
YES >> Check the components. Refer to DI-19, "Electrical Component Inspection" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
DTC [U1000] CAN Communication CircuitINFOID:0000000001704507
Symptom: Display CAN COMM CIRC [U1000] at the result of self-diagnosis for combination meter.
1.CHECK CAN COMMUNICATION
1. Select "SELF-DIAG RESULTS" mode for "METER/M&A" with CONSULT-III.

Tow Truck TowingINFOID:0000000001702452
CAUTION:
• All applicable local laws regarding the towing operation must be obeyed.
• It is necessary to use proper towing equipment to avoid possible damage to the vehicle during tow-
ing operation. Towing is in accordance with Towing Procedure Manual at dealer.
• Always attach safety chains before towing.
• When towing, make sure that the transmission, steering system and power train are in good order. If
any unit is damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving (front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
CAUTION:
Never tow an automatic transaxle model with four wheels on the ground as this may cause serious
and expensive damage to the transaxle.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000001702453
• Tow chains or cables must be attached only to the main structural members of the vehicle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cooling
systems.
• Always pull the cable straight out from the front or rear of the vehicle. Never pull on the vehicle at an angle.
• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.
WARNING:
• Do not spin the tires at high speed. This could cause them to explode and result in serious injury.
Parts of the vehicle could also overheat and be damaged.
• Install removable recovery hook securely using wheel nut wrench.
