indicated on the screen as a vehicle mark. More accurate data is judged and used by comparing vehicle posi-
tion detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.
Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.
Map-Matching
Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from Map
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In this case, the vehicle mark on the display must be cor-
rected manually.
In map-matching, alternative routes to reach the destination will
be shown and prioritized, after the road on which the vehicle is
currently driven has been judged and the vehicle mark has been
repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in different order of priority, and the incorrect road
can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and
configuration of the road.

Gyroscope
(angular velocity sensor)Can detect the vehicle's turning angle quite
accurately.Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna
(GPS information)Can detect the vehicle's travel direction
(North/South/East/West).Correct direction cannot be detected when vehi-
cle speed is low.

Steering Angle Adjustment
The steering angle output value detected with the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed etc., perform this procedure.
ERROR HISTORY
The diagnostic results of “Self-diagnosis” determine if any malfunction occurred between selecting “Self-diag-
nosis” and displaying “Self-diagnostic Results”.
If an error occurred before the ignition switch was turned ON and does not occur again until “Self-diagnosis” is
completed, the trouble diagnosis result will be judged normal. Therefore, errors in the past which cannot be
found by “Self-diagnosis”, must be found by checking the “Error record”.
The error history shows the error occurrence frequency in past. The frequency of occurrence is displayed by 2
types: the count down type and the count up type. Select either type according to the error item.
In “Error History” of models with NAVI, time and place that the selected error last occurred are displayed. Be
careful about the following.
If there is a malfunction with the GPS antenna circuit board in the NAVI control unit, the correct date of
occurrence may not be able to be displayed.
Place of the error occurrence is represented by the position of the current location mark at the time an
error occurred. If current location mark has deviated from the correct position, then the place of the error
occurrence cannot be located correctly.

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions for Brake ControlNFS000Q1
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is normal condition.
When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and oil leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
ABS might be out of order or malfunctions by putting a radio (wiring inclusive), an antenna and a lead-in
wire near the control unit.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
VDC system may not operate normally or a VDC OFF indicator lamp or SLIP indicator lamp may light.
–When replacing the following parts with parts other than genuine parts or making modifications: Suspen-
sion-related parts (shock absorber, spring, bushing, etc.), tires, wheels (other than specified sizes), brake-
related parts (pad, rotor, caliper, etc.), engine-related parts (muffler, ECM, etc.) and body reinforcement-
related parts (roll bar, tower bar, etc.).
–When driving with worn or deteriorated suspension, tires and brake-related parts.

On-Vehicle Inspection and ServiceNES000IA
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IB
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .

6. Each mounting part of axle and suspension for looseness and deformation.
7. Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and
other damage.
8. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.
Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
