 In map-matching, alternative routes are prepared and prioritized in addition to the road judged currently driven. Due to the distance
and/or direction error, the incorrect road may be prioritized and
current-location mark may be repositioned to the wrong road.
When two roads are running in parallel, they are judged to the
same priority. Therefore, the current-location mark may appear on
either of them alternately, depending on maneuvering of the steer-
ing wheel and configuration of the road.
 Map-matching does not function correctly when a road on which the vehicle is driving is new and not recorded in the DVD-ROM, or
when road pattern stored in the map data and the actual road pat-
tern are different due to repair.
When driving on a road not present in the map, the map-matching
function may find another road and position the current-location
mark on it. Then, when the correc t road is detected, the current-
location mark may change to it.
 Effective range for comparing the vehicle position and travel direc-
tion calculated by the distance and direction with the road data
read from the 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.
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) ac cording to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver ca lculates the vehicle's position in
two dimensions (latitude/longitude) , and utilize the altitude data cal-
culated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
 In two-dimensional positioning, GPS accuracy will deter iorate when altitude of the vehicle position changes.
 The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
 Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do not
reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from the
GPS satellites may not be received when so me object is located over the GPS antenna.
NOTE:
 Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).
 Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

A mark has been placed on each body panel to indicate the parts matching positions. When repairing parts
damaged by an accident which might affect the vehicle stru cture (members, pillars, etc.), more accurate and
effective repair will be possible by using these ma rks together with body alignment specifications.
DESCRIPTION
 All dimensions indicated in the figures are actual.
 When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge itself
to make sure there is no free play.
 When a measuring tape is used, check to be su re there is no elongation, twisting or bending.
 Measurements should be taken at the center of the mounting holes.
 An asterisk (*) following the value at the measuring poi nt indicates that the measuring point on the other side
is symmetrically the same value.
 The coordinates of the measurement points are the distances measured from the standard line of ″X ″, ″Y ″
and ″Z ″.

4. Heat cylinder head to 110 to 130
°C (230 to 266 °F) by soaking in
heated oil.
5. Using the valve guide drift (commercial service tool), press valve guide from camshaft side to the dimensions as in the figure.
WARNING:
Cylinder head contains heat . When working, wear protec-
tive equipment to avo id getting burned.
6. Using the valve guide reamer (commercial service tool), apply reamer finish to valve guide.
VALVE SEAT CONTACT
 After confirming that the dimensions of valve guides and valves arewithin the specifications, perform this procedure.
 Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the valve contact on the surface.
 Check if the contact area band is continuous all around the circum-
ference.
 If not, grind to adjust valve fitting and check again. If the contacting surface still has “NG” conditions even after the re-check, replace
valve seat. Refer to "VALVE SEAT REPLACEMENT".
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-149, "
Standard and Limit".
CAUTION:
Prevent to scratch cylinder head by excessive boring.

2. Ream cylinder head recess diameter for service valve seat.
 Be sure to ream in circles concentric to valve guide center.This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. WARNING:
Cylinder head contains heat. When working, wear protecti ve equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.
5. Using the valve seat cutter set (commercial service tool) or valve
seat grinder, finish seat to the specified dimensions. Refer to
EM-149, "
Standard and Limit".
CAUTION:
When using the valve seat cutter, firmly grip cutter handle
with both hands. Then, pr ess on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to "VALVE SEAT CONTACT".
VALVE SPRING SQUARENESS
 Set a try square along the side of valve spring and rotate spring. Measure the maximum clearance between the top of spring and try
square.
 If it exceeds the limit, replace valve spring.
