DESCRIPTION
OutlineINFOID:0000000001328805
The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle
ahead according to that vehicle's speed, or at the set speed, if the road ahead is clear.
The ICC function has two cruise control modes and brake assist (with preview function).
VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
With vehicle-to-vehicle distance control mode, the driver can maintain the same speed as other vehicles with-
out the constant need to adjust the set speed as the driver would with a normal cruise control system.
The system is intended to enhance the operation of the vehicle when following the vehicle traveling in the
same lane and direction.
If the distance sensor detects a sl ower moving vehicle ahead, the system wil l reduce speed so that the vehicle
ahead can be followed at the selected distance.
The system automatically controls the throttle and applie s the brakes (up to 25% of vehicle braking power) if
necessary.
The detection range of the sensor is approximately 120 m (390 ft) ahead.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE
Conventional (fixed speed) cruise contro l mode is cruising at preset speeds.
Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.
BRAKE ASSIST (WITH PREVIEW FUNCTION)
When the force applied to brake pedal exceeds a certain level, the Brake Assist is activated and generates a
greater braking force than that of a convent ional brake booster even with light pedal force.
When the Preview Function identifies the need to apply the sudden brake by sensing the vehicle ahead in the
same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver depress
the brake pedal and improves brake re sponse by reducing its free play.
Refer to Owner's Manual for BRAKE ASSIST (W ITH PREVIEW FUNCTION) operating instructions.

DESCRIPTION
 Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.
 Self Diagnosis mode checks for connections between the uni ts constituting this system, analyzes each indi-
vidual unit at the same time, and displays the results on the display.
 Confirmation/Adjustment mode displays trouble diagnos is that require an operation and a judgment by a
human (auto-decision cannot be performed by the system) , confirmation of preset value, and an error his-
tory.

The steering angle output value detected by 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 adjus tment is necessary when the tire
chains are installed, et c., perform this procedure.
Error History
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting “Self Diag-
nosis” until self-diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “Sel f Diagnosis”, and if an error does not occur until self-
diagnosis results is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with “Error His tory” for the past error that is not available
with self-diagnosis.
“Error History” displays the time and place of the most re cent occurrence of that error. However, take note of
the following points.
 Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the NAVI
control unit has malfunctioned.
 Place of the error occurrence is represented by the pos ition of the vehicle mark at the time when the error
occurred. If the vehicle mark has deviated from the co rrect position, then the place of the error occurrence
may not be located correctly.
 When the ignition switch is turned ON if the error is det ected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON t he next time, the counter does not decrease.
 The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log” switch.

Symptom Possible cause Possible solution
The message “Error” appears. The DVD-ROM is dirty or partially damaged. Check the DVD-ROM and wipe it clean with a
soft cloth.
If any damage, replace the DVD-ROM.
Symptom Possible cause Possible solution
In the auto re-route calculation,
waypoints are not included. Waypoints that you have already passed are not
included in the auto re-route calculation. To go to that waypoint again, it is necessary to
edit the route.
Route information is not displayed. Route calculation has not yet been performed.
Set the destination and perform route calcula-
tion.
Vehicle is not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on the route guidance.
The auto re-route calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculations took priority conditions into
consideration, but the same route was calculat-
ed.
This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route, in-
cluding the ones that you have already passed. A maximum of 5 waypoints can be set on the
route. If you want to go to 6 or more waypoints,
perform route calculations several times, as
necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculat-
ed.
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 your trip by selecting one or two interme-
diate destinations, and perform a global route
calculation based on multiple route calcula-
tions.
There are time restricted roads (day of week,
time) near the current vehicle location or desti-
nation. Set [Use Time Restricted Roads] to off.
The part of the route already
passed is deleted. A route is managed by sections between way-
points. If passing 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.
An indirect route is suggested. If there are restrictions (such as one-way
streets) on roads close to the starting point or
destination, the system may suggest an indirect
route.
Adjust the location of the starting point or desti-
nation.
The system may suggest an indirect route be-
cause route calculation does not take into con-
sideration some areas such as narrow streets
(grey roads). Reset the destination to a main or ordinary
road, and recalculate the route.
The landmark information does not
correspond to the actual informa-
tion. This may be caused by insufficient or incorrect
data on the DVD-ROM.
Updated information will be included in the next
version of the DVD-ROM.
The suggested route does not ex-
actly connect with the starting
point, waypoints, or destination. There is no data for route calculation closer to
these locations. Set the starting point, waypoints and destina-
tion on a main road, and perform route calcula-
tion.
