SYSTEM DESCRIPTION
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:
TheroadmapdataisbasedondatastoredinthemapDVD-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.
lIn 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.
lMap-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the
actual road pattern are different due to repair.
When driving on a road not present in the map, the map-match-
ing function may find another road and position the vehicle mark
on it. Then, when the correct road is detected, the vehicle mark
may change to it.
lEffective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between current vehicle position and
the position on the map, correction by map-matching is not possible.

TROUBLE DIAGNOSIS
PlaceIn a parking lotWhen driving in a parking lot, or
other location 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 deviated from the correct loca-
tion.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, and the vehicle
mark may deviate from the correct
location.
If after traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction. TurntableWhentheignitionswitchisOFF,the
navigation system cannot receive
the signal from the gyroscope
(angular speed sensor). Therefore,
the displayed direction may be
incorrect and the correct road may
not be easily returned to after rotat-
ing the vehicle on a turntable with
the ignition OFF.
Slippery roadsOn 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.
SlopesWhen 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 dataRoads not displayed on the map
screenWhen 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 devi-
ate 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 vehi-
cle mark may deviate from the cor-
rect road. Cause (condition) Driving condition Remarks (correction, etc.)

TROUBLE DIAGNOSIS
–Because calculation of the current location cannot be done when traveling with the ignition OFF, for exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tioncanbedetectedwithGPS,thelocationwillbecorrected.
THE CURRENT POSITION MARK JUMPS.
In the following cases, the current location mark may appear to jump as a result of automatic correction of the
current location.
lWhen map matching has been done
–If current location and the current location mark are different when map matching is done, the current
location mark may seem to jump. At this time, the location may be “corrected” to the incorrect road or to a
location which is not on a road.
lWhen GPS location correction has been done
–If current location and the current location mark are different when location is corrected using GPS mea-
surements, the current location mark may seem to jump. At this time, the location may be “corrected” to a
location which is not on a road.
THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA.
The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
CURRENT LOCATION MARK ROTATES WITHOUT OPERATION
If the ignition switch is turned ON with the turntable rotating, the rotating condition is recorded as the stop con-
dition. Therefore, the current location mark might rotate when actually stopping.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE CORRECT PLACE AND SOMETIMES IT IS IN THE INCORRECT PLACE.
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and operation of the steering wheel, the location detection results will be dif-
ferent. Therefore, even on a road on which the location has never been incorrect, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW.
lThe map matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.
lBecause of the way map matching operates, when there are many roads running in similar directions in
the surrounding area a matching determination may be impossible. The location will remain uncorrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.
lGPS accuracy has a malfunction range of about 10 m. In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
lThe navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one that is determined to have higher accuracy is used.
lPosition correction by GPS is not available while the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.
The current place name might not be displayed when there is no name of place information in the map screen.
THE DISPLAY IS DIFFERENT BETWEEN BIRDVIEW®AND (FLAT) MAP DISPLAY.
The following is different at birdview®.
lThe current place name displays names that are primarily in the direction of vehicle travel.
lThe amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
lThe conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
lSome trimming of the character data is done to prevent the display from becoming too complex. In some
cases and in some locations, the display contents may differ.
lThe same place name, street name, etc. may be displayed multiple times.

(except trip A and DTE).
NOTE:
lAfter the display changes automatically, the indication can be
changed to the next mode by pressing the odo/trip meter switch.
lThe record of the odometer is kept even if the battery cable is disconnected.
TRIP COMPUTER
Function
The trip computer can indicate the following items.
lDTE (distance to empty)
lAverage fuel economy
lAverage vehicle speed
lRunning time
DTE (Distance to Empty) Indication
The DTE indication provides the driver with the distance estimation that can be driven before refueling. The
DTE is calculated by signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption) and ABS
actuator and electric unit (control unit) (vehicle speed). The indication is refreshed every 30 seconds. When
fuel remaining is less than approximately 11.6 (2 1/2 Imp gal), the indication blinks as a warning. If the fuel
remaining is less than approximately 9.6 (2 1/8 Imp gal), the indication shows “---”. In this case, the display
changes to the DTE mode from the different mode. When the battery cable is disconnected and reconnected,
DTE mode displays “---” until the vehicle is driven 0.5 km.
Average Vehicle Speed Indication
Average vehicle speed indication is calculated by running distance and running time. The indication is
refreshed every 30 seconds. If average vehicle speed is reset, average fuel consumption is reset at the same
time. At about 0.5 km and for 30 seconds after resetting, the display shows “- ”®“- ”®“-”®“ -”.
Average Fuel Economy Indication
Average fuel consumption indication is calculated by signals from ABS actuator and electric unit (vehicle
speed) and the ECM (fuel consumption). The indication is refreshed every 30 seconds. At about 0.5 km and
for 30 seconds after resetting, the display shows “- ”®“- ”®“-”®“ -”.
Running Time Indication
Trip time displays ignition switch ON time cumulatively. If trip time is reset, trip distance is reset at the same
time.

EC
When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed, engine
coolant temperature and fuel rail pressure.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal or idle
control.
IDLE CONTROL
Input/Output Signal Chart
*: The input signal is sent to the ECM through CAN communication line.
When the ECM determines that the engine speed is at idle, the fuel injection system is adapted for the idle
control. The ECM regulates the amount of fuel injected corresponding to changes in load applied to the engine
to keep engine speed constant. The ECM also provides the system with a fast idle control in response to the
engine coolant temperature signal.
NORMAL CONTROL
Input/Output Signal Chart
The amount of fuel injected under normal driving conditions is deter-
mined according to sensor signals. The crankshaft position sensor
detects engine speed, the accelerator pedal position sensor detects
accelerator pedal position and fuel rail pressure sensor detects fuel
rail pressure. These sensors send signals to the ECM.
The fuel injection data, predetermined by correlation between vari-
ous engine speeds, accelerator pedal positions and fuel rail pres-
sure are stored in the ECM memory, forming a map. The ECM
determines the optimal amount of fuel to be injected using the sen-
sor signals in comparison with the map.
