6■Points to note before useStarting the engine before using the system
The navigation system can be used with the ignition key in
either the ON position or the ACC position. To preserve the
battery, however, it should be used with the engine running
whenever possible. Using the system for a long time with
the engine off can cause the battery to run down.Delay before display of current position
The system will not immediately display a correct indication
of your vehicle’s current position after being switched on for
the first time or after the battery has been disconnected for
a long time. It will display a correct current position
indication as soon as it receives Global Positioning System
(GPS) signals.Program reloading after battery disconnection
The navigation program will be erased from the system’s
memory if the battery is disconnected. If this happens, load
the provided DVD-ROM disc in the system’s main unit and
turn the ignition switch to the ON or ACC position. The
system will automatically reload the program and start
operating normally again.Incorrect operation on rough roads
The system may operate incorrectly or be unable to read the
data on the DVD-ROM disc when subjected to severe
vibration caused by driving on rough roads.
Handling the GPS antenna
Do not paint the antenna. Doing so could impair or prevent
signal reception.Disabled switches
Some switches are disabled during operation of the system.
These switches are displayed in fainter colors and no
messages are displayed for them.Risk of damage to the main unit
Be mindful of the occupant compartment temperature.
Using the system when the occupant compartment
temperature is extremely high or low can damage it or cause
it to malfunction. Also, note that the system’s main unit can
be damaged by strong vibration and by any metallic object or
water that gets inside.Condensation
Condensation can form on the lens inside the main unit
when there is a rapid change in occupant compartment
temperature (for example, when the heater is switched on in
cold weather). Such condensation can cause the system to
operate abnormally. If you wait an hour or so for the
condensation to disappear, the system should start working
normally again. If normal operation is still not restored after
several hours, we recommend that you contact the nearest
SUBARU dealer.

■Accuracy of vehicle positionArea in which GPS signals cannot be received
Because the radiowave signals from the GPS satellites travel
primarily by line of sight, the navigation system might not be
able to receive the signals in the areas described below.
(If the GPS mark does not appear on the map screen, it
means that the GPS radiowave signals are not being
properly received.)
(1) Inside a tunnel
(2) Inside a building
(3) Under a three-dimensional road system such as for high-
speed roads
(4) On boulevards lined with trees
(5) Between buildings
(6) Under a cliff or in a cave
• If the GPS antenna or its surroundings are blocked by an
obstacle (including cargo), it might not be possible for the
system to receive the GPS radiowave signals.
• If multiple paths are created due to the reflection from
buildings, a large measurement error could occur, causing
the vehicle’s mark to deviate from its actual position.Deviation of the vehicle’s position mark
The vehicle’s position mark could deviate from its actual
position when the vehicle is being driven under the
conditions listed below or due to conditions of the GPS
satellites.If the vehicle travels on a road whose actual shape differs
from that in the map data, the vehicle’s mark could deviate
from the actual position. The correct position will eventually
appear on the screen through the correction function. If the
screen does not show the correct position for an excessively
long time, correct the current position or make an automatic
correction.
(1) The vehicle’s mark could appear on a parallel road.
(2) When the road splits into a narrow Y, the vehicle’s mark
could appear on the other fork of the Y.
(3) When the vehicle makes a right or left turn, the vehicle’s
mark could appear on one street ahead or behind.
(4) If the vehicle is transported by means other than the
vehicle’s own power, such as on a ferryboat, the
vehicle’s mark will remain in the position it was before
the transport until the system can calculate the position
through the GPS.
(5) When the vehicle is driven on a steep incline, the
vehicle’s mark could deviate from its actual position.
(6) If there are continuous gradual curves in the same
direction, the vehicle’s mark could deviate from its
actual position.
(7) If the vehicle is driven in a zigzag pattern, such as
through frequent lane changes, the vehicle’s mark could
deviate from its actual position.
(8) If the vehicle is placed on a turntable, such as in a
parking area, and turned with the ignition OFF, the
vehicle’s mark could deviate from its actual orientation.General Information
