only upon replacing the multi-display, a beeping sound
can be heard for 3 seconds (while the initial screen is dis-
played) after turning the ignition switch to the ACC posi-
tion.

Perform the automatic adjustment again if a beeping
sound can be heard within 3 seconds.

SYSTEM NORMAL CONDITION CHECK
(f) 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.
(g) 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 the vehicle actually runs on.
(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.

(4) When the vehicle is carried, such as on a ferry, and
the vehicle itself is not running, the current vehicle
position mark may be displayed in the position
where the vehicle was until a measurement can be
performed by GPS.
(5) When the vehicle runs on a steep hill, the current ve-
hicle position mark may deviate from the correct
position.
(6) When the vehicle makes a continuous turn of 360,
720, 1,080, etc. degrees, the current vehicle posi-
tion mark may deviate from the correct position.
(7) When the vehicle moves erratically, such as
constant lane changes, the current vehicle position
mark may deviate from the correct position.
(8) When the ignition switch is put into the ACC/OFF
position on a turn table before parking, the current
vehicle position mark may not point in the correct
direction. The same will occur when the vehicle
comes out of parking.

(9) When the vehicle runs on the snowy road or a
mountain path with the chains installed or using a
spare tire, the current vehicle position mark may
deviate from the correct position.
(10) When a tire is changed, the current vehicle position
mark may deviate from the correct position.
HINT:

Diameter of the tire may change, causing a speed sensor
error.

Performing the ºtire changeº in calibration mode will allow
the system to correct the current vehicle position faster.
