SYSTEM DESCRIPTION
1. SYSTEM NORMAL CONDITION CHECK
(a) If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.
SymptomAnswer
A longer route than expected is chosen.Depending on the road conditions, the navigation ECU may determine that a longer
route is quicker.
Even when distance priority is high, the shortest route is not
shown.Some paths may not be advised due to safety concerns.
When the vehicle is put into motion immediately after the
engine starts, the navigation system deviates from the actu-
al position.If the vehicle starts before the navigation system activates, the system may not
react.
When running on certain types of roads, especially new
roads, the vehicle position deviates from the actual position.When the vehicle is driving on new roads not available on the map disc, the system
attempts to match it to another nearby road, causing the position mark to deviate.
(b) The following symptoms are not a malfunction, but are
caused by errors inherent in the GPS, gyro sensor, speed
sensor, and navigation ECU.
(1) The current position mark may be displayed on a
nearby parallel road.
(2) Immediately after a fork in the road, the current ve-
hicle position mark may be displayed on the wrong
road.
(3) When the vehicle turns right or left at an intersec-
tion, the current vehicle position mark may be dis-
played on a nearby parallel road.

DIAGNOSIS SYSTEM
HINT:

Illustrations may differ from the actual vehicle depending on the device settings and options. There-
fore, some detailed areas may not be shown exactly the same as on the actual vehicle.

After the ignition switch is turned on, check that the map is displayed before starting the diagnostic
mode. Otherwise, some items cannot be checked.
1. There are 2 methods to start diagnostic mode. Start the mode by using one of them.
2. Method 1
(a) Start the engine.
(b) While pressing and holding ºINFOº switch, operate the
light control switch, OFF " TAIL " OFF " TAIL " OFF
" TAIL " OFF.
(c) The diagnostic mode starts and the service check screen
(ºSystem Check Modeº) will be displayed. Service inspec-
tion starts automatically and the result will be displayed.
3. Method 2
(a) Start the engine.
(b) Switch to the ºDisplay quality adjustmentº screen.
(c) From the display quality adjustment screen, touch the
corners of the screen in the following order: upper left "
lower left "upper left " lower left " upper left " lower
left.
(d) The diagnostic mode starts and ºService Checkº screen
will be displayed. Service inspection starts automatically
and the result will be displayed.
4. Diagnosis MENU
(a) Diagnostic screen will be displayed by pressing the menu
switch on the service check screen.
