DescriptionINFOID:0000000001326766
SYSTEM DESCRIPTION
*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
This system controls flow rate of fuel vapor from
the EVAP canister. The opening of the vapor by-pass pas-
sage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/O FF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engi ne control. The optimum value stored in the ECM is
determined by considering various engine conditions. When t he engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canis-
ter. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

GENERAL MAINTENANCE
Explanation of Gene ral MaintenanceINFOID:0000000001328893
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 INFINITI 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, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if nec-
essary. Check carefully for damage, cuts or excessive wear. —
Wheel nuts When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary. —
Windshield Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. —
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-31
Transmitter compo-
nents in tire pressure
monitoring system
(TPMS)Replace grommet seal, valve core and cap of the transmitter in TPMS every tire
replacement by reaching wear limit of tire.
WT-10
Wheel alignment and
balanceIf the vehicle pulls 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 align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed. MA-30
,
FSU-5
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 smoothly as well as the trunk
lid and back hatch. 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 lubri-
cation frequently. MA-35
Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis. —
Item
Reference page
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. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in) —
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage. MA-35

AUTOMATIC DRIVE POSITIONER
AUTOMATIC DRIVE POSITIONER
System DescriptionINFOID:0000000001328097
 The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
drive positioner control unit can also store the optimum driving positions (driver seat, steering wheel position
(tilt, telescopic) and door mirror position) for 2 people. If the driver is changes, one-touch operation allows
changing to the other driving position.
 The settings (ON/OFF) of the automatic sliding s eat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display contro l unit to driver seat control unit.
 Using CONSULT-III, the seat slide and steering wheel amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position [seat position, steering wheel posit ion (tilt, telescopic) and door mirror position] can be
adjusted with the power seat switch or ADP steering switch or door mirror remote control switch.
NOTE:
 The seat can be manually operated with the ignition switch OFF.
 The door mirrors can be manually operated with the ignition switch turned ACC or ON.
AUTOMATIC OPERATION
NOTE:
 Disconnecting the battery erases the stored memory.
 After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open) →OFF (close) →ON
(open), the Entry/ Exiting operation becomes possible.
 After exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON →START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
MEMORY STORING AND KEYFOB INTERLOCK STORING
 Store the 2 driving positions and shifts to t he stored driving position with the memory switch.
Function Description
Memory switch operation The seat, steering and door mirror move to the stored driving position by pushing
memory switch (1 or 2).
Entry/Exiting function Exiting operation At exit, the seat moves backward and steering wheel moves forward/upward.
Entry operation
At entry, the seat and steering wheel returns from the exiting position to the previous
driving position.
keyfob interlock operation Perform memory operation, exiting operation and entry operation by pressing keyfob
unlock button.
Auto operation temporary stop
conditions. When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.  When the vehicle speed becomes 7 km/h (4 MPH) or higher.
 When the setting switch, memory switch 1, or 2 are pressed.
 When A/T selector lever is in any position other than P.
 When the door mirror remote control switch is operated (when ignition switch turned to
ON or ACC).
 When power seat switch turned ON.
 When ADP steering switch turned ON (telescopic operation or tilt operation).
 When door mirror operates (only memory switch operation).
 When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).
 When steering wheel tilt and telescopic Entry/Exiting setting is OFF (only entry/exiting op-
eration).
 When the tilt and telescopic sensor malfunction is detected.
