SWITCHES
33
To turn the lights on, twist the knob on the end of the lever.
FIRST CLICKSTOP: Only the parking, tail, license plate,
side marker and instrument panel lights turn on.
SECOND CLICKSTOP: Headlights also turn on.
THIRD CLICKSTOP (ºAUTOº): The headlights and all
other lights automatically turn on depending on the darkness
of the surroundings.
When the headlights are on, the headlight indicator lights up
in the instrument cluster.
Manually twist the knob to the second clickstop to turn on
the headlights if they are needed immediately when
entering a dark tunnel, parking structure, etc.

SWITCHES
34
The automatic light control sensor is on top of the driver's
side instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.
The lights automatically turn off when the driver's door is
opened with the ignition key turned to the ºACCº or ºLOCKº
position. To turn them on again, turn the ignition key to the
ºONº position or turn the headlight switch off and then twist
the knob until the first or second clickstop. If you are going
to park for over one week, make sure the headlight switch is
off.
When the headlight switch is turned to the first or second
clickstop, the brightness of the instrument cluster will be
reduced slightly unless the instrument panel light control
knob is turned fully on.

SWITCHES
35
Daytime Running Light System
The headlights turn on at reduced intensity when the parking
brake is released with the engine started, even with the light
switch in the ºOFFº position. They will not go off until the
ignition switch is turned off.
To turn on the other exterior lights and instrument panel
lights, twist the knob to the first clickstop.
Twist the knob to the second clickstop to turn on the
headlights to full intensity for driving at night.
When setting the knob to the third clickstop (ºAUTOº), the
headlights will automatically adjust to full intensity and/or
turn on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become
brighter, the headlights will turn to reduced intensity,
ultimately turning off the other lights.
NOTICE
To prevent the battery from being discharged, do not leave
the lights on longer than necessary when the engine is not
running.
HEADLIGHT DIMMER AND
TURN SIGNAL SWITCH

SWITCHES
36
For high beam, push the lever forward. Pull it back for
low beam. For the headlight flasher, pull it further back.
A blue light in the instrument cluster indicates high beam or
headlight flasher is on.
The headlight flasher works even when the headlight switch
is off.

SWITCHES
37
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ºONº position.
The turn signal is self±cancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also
signal a lane change by moving the turn signal lever partway
and holding it there.
If the green light in the instrument cluster flashes faster than
normal, it indicates that the front or rear turn signal bulb has
burned out. If this indicator light does not come on,
the fuse
or the indicator light itself has probably failed.
FOG LIGHT SWITCH
To turn on the fog lights, turn the switch to the ºONº
position. The fog lights come on only when the headlights
are on low beam.

SWITCHES
38
WINDSHIELD WIPER ANDWASHER SWITCH
To turn the wipers on, move the lever down. To make the
washer squirt, push the button on the end of the lever.
The ignition key must be in the ºONº position.
For mist wiper operation (a single wipe), pull the lever toward
you and release it.
The interval adjuster lets you adjust the wiping time interval
between wiper sweeps if the wiper lever is in the ºINTº
position. Tw ist the lever upward to increase the time between
sweeps, and downward to decrease it.
Also, the wipers will automatically operate a couple of times
after the washer squirts even with the lever in the ºOFFº
position. The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes nearly
empty. For information on adding washer fluid, see ºAdding
washer fluidº on page 396.
In cold weather, warm the windshield with the defroster
before using the washer. This will help prevent icing, which
could block your vision.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.

SWITCHES
39
REAR WINDOW AND OUTSIDEREAR VIEW MIRRORDEFOGGER SWITCH
To turn the electric rear window defogger on, push the
switch.
The ignition key must be in the ºONº position.
The thin heater wires on the inside of the rear window and the
heater panels in the outside rear view mirrors will quickly
clear the surface. An indicator light is on when the defogger
is operating.
The system will automatically shut off when the defogger has
operated about 15 minutes.

SWITCHES
40
CAUTION
Since the mirror surfaces can get hot, keep your hands off
them when the switch is on.
If further defrosting or defogging is desired, simply actuate
the switch again. When the surface has cleared, push the
switch once again to turn the defogger off. Continuous use
may cause the battery to discharge, especially during
stop±and±go driving. The defogger is not designed to dry rain
water or to melt snow.
If the outside rear view mirrors are heavily coated with ice,
use a spray de±icer before operating the switch.
NOTICE

When cleaning the inside of the rear window, be
careful not to scratch or damage the heater wires.

To prevent the battery from being discharged, do not
operate the defogger continuously longer than
necessary.

switch on the driver's door.
The power windows work when the ignition key is in the
ºONº position.
Key off operation: Even if the ignition key is turned to the
ºACCº or ºLOCKº position, the window can be operated
until any of the doors is opened (or for about 60 seconds).

SWITCHES

To raise or lower the windows, pull the switch halfway up
or push it halfway down.
Automatic operation: To fully lower the window
