NAVIGATION
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.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
MAP DVD-ROM
ROUTE CALCULATION AND VISUAL GUIDANCE
The location of vehicle icon is mis-
aligned from the actual position.When using tire chains or replacing the tires, speed
calculations based on the speed sensor may be
incorrect.Drive the vehicle for a while [at approxi-
mately 30km/h (19 MPH) for about 30
minutes] to automatically correct the vehi-
cle icon position.
If this does not correct the vehicle icon
position, contact an INFINITI dealer.
The map data has mistake or is incomplete (the
vehicle icon position is always misaligned in the
same area).Updated road information will be included
in the next version of the map DVD-ROM. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. Map DVD-ROM is dirty or partially damaged.Check the DVD-ROM and wipe it clean
with a soft cloth.
If there is any damage, replace the DVD-
ROM.
Symptom Possible cause Possible solution
In the auto reroute calculation,
waypoints are not included.Waypoints already passed are not included in the
auto reroute calculation.In case of going to that waypoints again,
edit the route.
Route information is not displayed.Route calculation has not yet been performed.Set the destination and perform route cal-
culation.
The vehicle is not driven on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculation took priority conditions into con-
sideration, but the same route was calculated. This is not a malfunction.
A waypoint cannot be added.Five waypoints are already set on the route, includ-
ing ones that already passed.A maximum of 5 waypoints can be set on
the route. In case of going to 6 or more
waypoints, perform route calculations mul-
tiple times as necessary.
The suggested route is not dis-
played.Roads near the destination cannot be calculated.Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away.Divide the way by selecting one or two
intermediate destinations, and perform
route calculations multiple times.
There are time restricted roads (by day of week, by
time) near the current vehicle location or destina-
tion.Set “Use Time Restricted Roads” to off.
A part of the route is not displayed.The suggested route includes narrow streets (roads
displayed in gray).This is not a malfunction.
The part of the route already
passed is deleted.A route is managed by sections between way-
points. If you passed the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on the
area.)This is not a malfunction.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
PlaceIn a parking lot When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction. Turntable
When the ignition switch is off, the naviga-
tion system cannot get the signal from the
gyroscope (angular speed sensor). There-
fore, the displayed direction may be wrong
and the correct road may not be easily
returned to after rotating the vehicle on a
turntable with the ignition off.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
traveling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.
Map dataRoad not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair)
If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.
Ve h ic leUse of tire chains
When tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) Driving condition Remarks (correction, etc.)
