turn signal Lexus IS250 2010 Navigation Manual

Introduction
This manual explains the operation of the Navigation System.
Please read this manual carefully to ensure proper use. Keep this
manual in your vehicle at all times.
The Navigation System is one of the most technologically advanced
vehicle accessories ever developed. The system receives satellite sig-
nals from the Global Positioning System (GPS) operated by the U.S.
Department of Defense. Using these signals and other vehicle sen-
sors, the system indicates your present position and assists in locating
a desired destination.
The navigation system is designed to select efficient routes from your
present starting location to your destination. The system is also designed
to direct you to a destination that is unfamiliar to you in an efficient manner.
The system uses DENSO maps. The calculated routes may not be the
shortest nor the least traffic congested. Your own personal local knowl-
edge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes Point of Interest categories to
allow you to easily select destinations such as restaurants and hotels. If
a destination is not in the database, you can enter the street address or
a major intersection close to it and the system will guide you there.
The system will provide both a visual map and audio instructions. The au-
dio instructions will announce the distance remaining and the direction to
turn in approaching an intersection. These voice instructions will help you
keep your eyes on the road and are timed to provide enough time to allow
you to maneuver, change lanes or slow down.

shows your current position at any time
from any screen by pushing the “MAP/
VOICE” button.
While driving, the current vehicle position
mark is fixed on the screen and the map
moves.
The current position is automatically set as
the vehicle receives signals from the GPS
(Global Positioning System). If the current
position is not correct, it is automatically
corrected after the vehicle receives sig-
nals from the GPS.
INFORMATION
D After battery disconnection, or on
a new vehicle, the current position
may not be correct. As soon as the
system receives signals from the
GPS, the correct current position
is displayed.
D To correct the current position
manually, see page 311.

The system announces the approach to
the final destination.
1“Your destination is ahead.”
2“You have arrived at your des-
tination. The route guidance is
now finished.”

(in cases of poor GPS signal recep-
tion), the voice guidance may be
made early or delayed.

AUDIO/VIDEO SYSTEM
194
Turn the knob clockwise to step up the
station band or counterclockwise to
step down.
Your radio automatically changes to stereo
reception when a stereo broadcast is re-
ceived. “ST” appears on the screen. If the
signal becomes weak, the radio reduces
the amount of channel separation to pre-
vent the weak signal from creating noise.
If the signal becomes extremely weak, the
radio switches from stereo to mono recep-
tion. In this case, “ST” disappears from the
screen.(b) Presetting a station
1. Tune in the desired station.
2. Touch one of the buttons (1 — 6) you
want and hold it until a beep is heard.
This sets the station to the button and
the frequency appears on the button.
Each radio mode (AM, FM1 or FM2) can
store up to 6 stations. To change the pre-
set station to a different one, follow the
same procedure.
The preset station memory is cancelled
when the power source is interrupted by
battery disconnection or a blown fuse.
