Resetting the sunroof
Whenever the vehicle battery is discon-
nected or discharged, or you use the
emergency handle to operate the sun-
roof, you have to reset your sunroof sys-
tem as follows:
1. Turn the ignition key to the ON posi-tion.
2. According to the position of the sun- roof, do as follows.
1) in case that the sunroof has closedcompletely or been tilted
: Press the TILT UP button for 1 second.
2) in case that the sunroof has slide- opened
: Press and hold the CLOSE button for more than 5 seconds until the
sunroof has closed completely.
And then press the TILT UP but-
ton for 1 second
3. Then, release it.
4. Press and hold the TILT UP button once again until the sunroof has
returned to the original position of
TILT UP after it is raised a little higher
than the maximum TILT UP position.
When this is complete, the sunroof sys-
tem is reset.
Glass antenna (if equipped)
When the radio power switch is turned on
while the ignition key is in either the “ON”
or “ACC” position, your car will receive
both AM and FM broadcast signals
through the antenna in the rear window
glass.

CAUTION
• Do not clean the in side of the rear
window gla ss with a cleaner or
s craper to remove the foreign
deposits a s this may cause dam-
age to the antenna element s.
• Avoid adding metallic coating such as Ni, Cd, and so on. Thesecan disturb receiving AM and FMbroadcast signals.

How car audio works
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your car. This signal is
then received by the radio and sent to
your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area.AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.
FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build-
ings, mountains, or other obstructions.
These can result in certain listening con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:

Knowing your vehicle
• Fading - As your car moves away fromthe radio station, the signal will weaken
and sound will begin to fade. When this
occurs, we suggest that you select
another stronger station.
• Flutter/Static - Weak FM signals or large obstructions between the trans-
mitter and your radio can disturb the
signal causing static or fluttering nois-
es to occur. Reducing the treble level
may lessen this effect until the distur-
bance clears.
• Station Swapping - As a FM signal weakens, another more powerful sig-
nal near the same frequency may
begin to play. This is because your
radio is designed to lock onto the clear-
est signal. If this occurs, select anoth-
er station with a stronger signal. • Multi-Path Cancellation - Radio signals
being received from several directions
can cause distortion or fluttering. This
can be caused by a direct and reflect-
ed signal from the same station, or by
signals from two stations with close
frequencies. If this occurs, select
another station until the condition has
passed.
Using a cellular phone or a two-
way radio
When a cellular phone is used inside the
vehicle, noise may be produced from the
audio equipment. This does not mean
that something is wrong with the audio
equipment. In such a case, use the cellu-
lar phone at a place as far as possible
from the audio equipment.

CAUTION
When using a communication sys-tem such a cellular phone or a radio
set inside the vehicle, a separate external antenna mus t be fitted.
When a cellular phone or a radio set is u sed with an internal antenna
alone, it may interfere with the vehi- cle's electrical system and adver se-
ly affect safe operation of the vehi- cle.
WARNING
Don’t use a cellular phone when
you are driving. The driver should
stop at a safe place to use a cellular
phone.
