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 remote transmitter.
The system does not operate when the key is inserted into the ignitionswitch.
System operation
The security system will give the following alarm indications when trig-
gered: The turn signal lights will flash and the horn will sound intermit-
tently. In addition, the starter motor will not operate. The alarm automatically resets after 30 seconds; however, the
alarm will reactivate if the vehicle is tampered with again. The alarmwill 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. breaking glass or
forced entry). Note that there are two alarm levels for shock: warning
and alarm. In warning mode, the alarm detects lower level vibrations
and triggers 2 warning chirps on the horn and two flashes on the
lights as a deterrent to would be vandals. In alarm mode, higher lev-
els of shock are detected and the system will go into full alarm. Ignition switch being turned on while in armed state.
NOTE
With the valet mode selected, the security system does not oper-
ate and the parking lights do not flash when the remote transmit-ter is used for locking and unlocking.The security system indicator light in the combination meter
flashes twice per second to show that the valet mode is selected.For details, refer to “Valet mode ” in this section.

the transmitter.
Tripped sensor identification
If an electronic chirp sounds four times and the turn signal lights flash
four times when you disarm the system, this indicates that the alarm
was triggered. The number of times the indicator light flashes indi-
cates 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 two times. ( “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 system ’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 indicator light will flash.
To exit this mode, close the door and turn the ignition switch to the
“ON” position.

Photosensors
HB6020BA
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 simi-
lar items. Periodically wipe the sensors clean using a piece of dry soft
cotton cloth or an applicator. nCompass calibration
1. For optimum calibration, switch off all nonessential electrical ac-
cessories (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 metallic 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 release, and thecompass 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).
5. The compass is now calibrated. Further calibration is not required.
The compass will automatically calibrate from this point forward.

AUTO mode operation:
The Automatic Climate Control system automatically controls the air
temperature of the passenger compartment in the AUTO mode. Whenthe “AUTO” switch is pressed, the indicator light “AUTO” on the con-
trol panel comes on. In this state, outlet air temperature, fan speed, air
flow distribution, air-inlet control, and air conditioner compressor op-
eration are automatically controlled.

NOTE The temperature setting remains even after the ignition switch is turned to the
“OFF”. However, if the battery cables are discon-
nected, the temperature will be set to 77 F (25 C) automatically.
Set desired temperature by turning the temperature control dial; turn
the dial clockwise to raise the temperature setting and turn it counter-clockwise to lower it.
The temperature can be set in increments of 1 F within a range of 65
– 85 F for US models and in increments of 0.5 C within a range of 18
– 32 C for Canadian models.
Even when quick cooling or warming is necessary, you do not have to
change the temperature setting. The Automatic Climate Control sys-
tem operates at maximum performance until the air in the passenger
compartment reaches to the specified temperature. Temperature sensors
This Automatic Climate Control system employs the several sensors.
These are very delicate parts. Therefore, if these sensors are dam-
aged, it is possible that the Automatic Climate Control system will not
properly control the air temperature in the passenger compartment.
To prevent possible damage to the sensors, please observe the fol-lowing: – Do not allow anything to impact the sensors.
– Be careful not to let water contact the sensors.
– Do not cover the sensors.
The sensors are found at the following locations: –Sun-load sensor (beside the windshield defroster grille)
– In-vehicle temperature sensor (beside the temperature control
dial.)– Ambient sensor (at the under side of the bumper)
