▼ Dashboard Illumination
(Without auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dashboard illumination is
dimmed.
(With auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dashboard illumination is
dimmed. However, when the light sensor
detects that the surrounding area is bright
such as when the position lights are turned
on in the daytime, the dashboard
illumination does not dim.
NOTE
(With auto-lig
ht control)
When the ignition is switched ON in the
early evening or at dusk, the dashboard
illumination is dimmed for several
seconds until the light sensor detects the
brightness of the surrounding area,
however, the dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-45.
The brightness of the instrument cluster
and dashboard illuminations can be
adjusted by rotating the knob.
The brightness decreases by rotating the
knob to the left. A beep sound will be
heard when the knob has been rotated to
the maximum dim position.
The brightness increases by rotating the
knob to the right.

Bright
Function for cancelling illumination
dimmer
The illumination dimmer can be canceled
by rotating the dashboard illumination
knob to the right until a beep sound is
heard while the instrument cluster is
dimmed with the ignition switched ON. If
the instrument cluster's visibility is
reduced due to glare from surrounding
brightness, cancel the illumination
dimmer.
NOTE
When the illumination dimmer is
canceled, the instrument cluster cannot
be dimmed even if the position lights are
turned on.
When the illumination dimmer is
canceled, the screen in the center
display switches to constant display of
the daytime screen.

CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wi per lever is in the AUTO position and the
ignition is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activa te automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely wh en it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if th e surrounding area becomes we ll-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffic ja ms inside tunnels, or in indoor parking lots.
In this case, the ligh ts turn off if the light switch is turned to the OFF position.
If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are
operated at low or high speed by the auto wi per control for several seconds, bad weather
conditions are determined and the headlights may be turned on.
The sensitivity of the auto-light control may be changed.

Auto-wiper control*
When the wiper lever is in the AUTO
position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically
(off―intermittent―low speed―high
speed).

The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch upward for higher sensitivity
(faster response) or rotate it downward for
less sensitivity (slower response).

Less sensitivitySwitch

position
CAUTION
 Do not shade the rain sensor by adhering
a sticker or a label on the windshield.
Otherwise the rain sensor will not
operate correctly.
When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
NOTE
Switching the auto-wiper lever from the
OFF to the AUTO position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
The auto-wiper control may not operate
when the rain sensor temperature is
about
－10 °C (14 °F) or lower, or
about 85 °C (185 °F) or higher.
If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.

If dirt or foreign matter (such as ice or
matter containing salt water) adheres to
the windshield above the rain sensor, or
if the windshield is iced, it could cause
the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set the wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.
If the auto-wiper lever is left in the
AUTO position, the wipers could
operate automatically from the effect of
strong light sources, electromagnetic
waves, or infrared light because the rain
sensor uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the OFF position other
than when driving the vehicle under
rainy conditions.
If the headlight switch and the
windshield wiper switch are in AUTO,
and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.
The auto-wiper control functions can be
turned off. Refer to Personalization
Features on page 9-9.
▼ Windshield Washer
