Keys and doors
to your vehicle.Security system (if equipped)
The security system helps to protect your vehicle and
valuables from theft. The horn sounds and the turn
signal lights flash if someone attempts to break into
your vehicle. The starter motor is also interrupted to
prevent starting the vehicle without a key.
The system can be armed and disarmed with the re-
mote transmitter.
The system does not operate when the key is inserted
into the ignition switch. !
System operation
The security system will give the following alarm indi-
cations when triggered:" The turn signal lights will flash and the horn will
sound intermittently. In addition, the starter motor will
not operate." The alarm automatically resets after 30 seconds;
however, the alarm will reactivate if the vehicle is tam-
pered with again. The alarm will continue for six times
if any sensor continues to be activated.
The alarm is triggered by: " Opening a door, the rear gate or trunk lid.
" Application of physical shock to the vehicle (e.g.

Keys and doors
In passive mode, the system will automatically
activate the alarm but WILL NOT automatically
lock the doors. In order to lock the doors you
must either lock them as indicated in step 4
above or with the key once they have been
closed. Failure to lock the doors manually will
result in a higher security risk.
! Disarming the system
To disarm the system, briefly press the “UNLOCK/
DISARM” button on the transmitter. " Tripped sensor identification
If an electronic chirp sounds four times and the turn
signal lights flash four times when you disarm the sys-
tem, this indicates that the alarm was triggered. The
number of times the indicator light flashes indicates
what sensor caused the alarm condition.
To enter identification mode:
1. Open the driver’s door and leave it open.
2. Turn the ignition switch to the “ON” position twotimes. (“LOCK” → “ON” → “LOCK” → “ON” →
“LOCK”)
3. The indicator light will start flashing. The indicator light provides the following indications.
Flashing one time:
Any door, the rear gate or the
trunk lid has been opened.
Flashing three times: The impact sensor in the sys-
tem’s unit has been activated. This may indicate that
your vehicle has been shocked or tampered with by
some outside force and/or unauthorized person.
Flashing four times: The ignition switch has been
turned on or the battery has been disconnected.
NOTE
The battery must be reconnected before the indi-
cator light will flash.
To exit this mode, close the door and turn the ignition
switch to the “ON” position.

!Auto-dimming mirror/compass (if equipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The inside electronic compass mirror has an anti-glare
feature which automatically reduces glare coming
from headlights of vehicles behind you. It also con-
tains a built-in compass." By pressing and releasing the left button, the auto-
matic dimming function is toggled on or off. When the
automatic dimming function is on, the auto dimming in-
dicator light (green) located to the right of the button will illuminate. "
By pressing and releasing the right button, the com-
pass display is toggled on or off. When the compass is
on, an illuminated compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode, the mirror sur-
face turns bright if the transmission is shifted into re-
verse. This is to ensure good rearward visibility during reversing. " Photosensors
The mirror has a photosensor attached on both the
front and back sides. If the glare from the headlights of
vehicles behind you strikes the mirror, these sensors

detect it and make the reflection surface of the mirror
dimmer to help prevent you from being blinded. For
this reason, use care not to cover the sensors with
stickers, or other similar items. Periodically wipe the
sensors clean using a piece of dry soft cotton cloth or
an applicator. "
Compass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger, heater/
air conditioning system, spotlight, etc.) and ensure all
doors are shut.
2. Drive to an open, level area away from large metal-
lic objects or structures and make certain the ignition
switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then re-
lease, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears from
the display (about two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurately.
You will know that this has occurred if your compass
begins to read in only limited directions. Should you
encounter this situation, return to step one of the
above procedure and recalibrate the mirror. "
Compass zone adjustment
Compass calibration zones
1. The zone setting is factory preset to Zone 8. Refer
to the “Compass calibration zone” map shown above
or one attached to the end of this manual to verify that
the compass zone setting is correct for your geograph-ical location.
2. Press and hold the right button for 3 seconds then
release, and the word “ZONE” will briefly appear and
then the zone number will be displayed.
3. Press the right hand button repeatedly to cycle the
display through all possible zone settings. Stop cycling
when the correct zone setting for your location is dis-

Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The semi-automatic climate control system employs
several sensors. These sensors are delicate. If they
are not treated properly and become damaged, the
system may not be able to control the interior temper-
ature correctly. To avoid damaging the sensors, ob-
serve the following precautions:
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors. The sensors are located as follows:
– Solar sensor: beside windshield defroster grille
– Interior air temperature sensor: beside the fan
speed control dial
– Ambient temperature sensor: behind front grille.
