instrument panel TOYOTA PRIUS 2004 2.G Navigation Manual

10
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct the
GPS signals.
The installation of window tinting may also ob-
struct the GPS signals. Most window tinting
contains some metallic content that will inter-
fere with the GPS signal reception. We ad-
vice against the use of window tinting on ve-
hicles equipped with navigation systems.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.Even when the navigation system is receiving
clear GPS signals, the vehicle position may
not be shown accurately or inappropriate
route guidance may occur in some cases.
(a) Accurate current vehicle posi-
tion may not be shown in the fol-
lowing cases:
When driving on a small angled Y−shaped
road.
When driving on a winding road.
When driving on a slippery road such as
in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run in
parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during high
speed driving.
When driving without setting the current
position calibration correctly.
After repeating a change of direction by
going forward and backward, or turning on
a turntable in the parking lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with tire chains installed.
When the tires are worn.
After replacing a tire or tires.
When using tires that are smaller or larger
than the factory specifications.

Depending on the position of the headlight
switch, the screen changes to the day
mode or night mode.
To display the screen in the day mode even
with the headlight switch on, touch “DAY
MODE” on the adjustment screen for bright-
ness and contrast control.
However, if the instrument panel light control
switch is turned fully to the right, mode switch-
ing cannot be done. It remains in the day
mode. In this case, “DAY MODE” is not shown
on the screen.
If the screen is set in the day mode with the
headlight switch turned to on, this condition is
memorized in the system even with the en-
gine turned off.
