CAUTION
Do not use sharp instruments or window
cleaner containing abrasives to clean the in-
ner surface of the rear window. They may

Mirrors
Always check that the inside and outside mirrors are
properly adjusted before you start driving. Inside mirror
1) Tab
The inside mirror has a day and night position. Pull
the tab at the bottom of the mirror toward you for the
night position. Push it away for the day position. The
night position reduces glare from headlights.
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. Italso contains a built-in compass. By pressing and releasing the left button, the au-
tomatic dimming function is toggled on or off. When the automatic dimming function is on, the auto dim-
ming indicator light (green) located to the right of

the button will illuminate. By pressing and releasing the right button, the
compass 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
surface turns bright if the transmission is shifted into
reverse. This is to ensure good rearward visibility
during reversing.
n 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 sen- sors 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. Periodi-
cally wipe the sensors clean using a piece of dry
soft cotton cloth or an applicator.
n Compass calibration
1. For optimum calibration, switch off all nonessen-
tial 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 me-
tallic objects or structures and make certain the igni-
tion switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then
release, 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). Thecompass is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurate-
ly. You will know that this has occurred if your com-
pass begins to read in only limited directions.
Should you encounter this situation, return to step
one of the above procedure and recalibrate the
mirror.

cator light located on the switch lights up while the
outside mirror defogger is operating.
The defogger will automatically shut off after about
15 minutes. If the mirror clears before that time,
push the switch to turn it off. It also turns off when
the ignition switch is turned to the “ACC” or “LOCK”
position. If defrosting or defogging is desired when
you restart your vehicle, you have to push the switch
to turn it on again. NOTE While the outside mirror defogger is operating, the rear window defogger also operates.
CAUTION
To prevent the battery from being discharged,
do not operate the defogger continuously for
any longer than necessary. Tilt steering wheel1. Adjust the seat position. Refer to the
“Front seat ”
section (chapter 1).
2. Push the tilt lock lever down.
3. Move the steering wheel to the desired level.
4. Pull the lever up to lock the steering wheel inplace.
5. Make sure that the steering wheel is securelylocked by moving it up and down.

Defogging with the air inlet selection lever set in the “” position provides better defogging
performance than in the “” position.
When the dial is placed in the “” or
“” position, the air conditioner compressor
operates automatically regardless of the position of the air conditioner button to defog the wind-
shield quickly.However the indicator on the air conditioner but-ton will not come on.Also, you cannot stop the air conditioner com-pressor by pressing the air conditioner button.
Air conditioner button (if equipped)
